Management of severe open tibial fractures: the need for combined orthopaedic and plastic surgical treatment in specialist centres

An evaluation of the management of severe open tibial fractures in the United Kingdom's major trauma centres

AIM

To evaluate the management of patients with severe open tibial fractures at major trauma centres (MTCs) in the UK with respect to BOAST 4 guidelines.

METHODS

Data collected by the Trauma and Audit Research Network (TARN) for all severe open tibial fractures treated at the 23 adult MTCs were evaluated. Key performance indicators (KPIs) included MTC admission under orthoplastics, administration of antibiotics within three hours of injury, initial debridement within 24 h and definitive fixation and soft tissue coverage within 72 h. Outcomes included 30-day infection rate, amputation rate and mortality rate. A score was calculated according to overall attainment of KPIs, and correlated to outcomes.

RESULTS

From 2014 to 2020, 3359 adults with Gustilo-Anderson (GA) IIIB and/or IIIC fractures were admitted to MTCs. Male to female ratio was 2:1 with a mean age of 43 and 65 years respectively. There was a negative correlation between KPI score and mortality rate (r=-0.4929, p = 0.0169). Direct admission to an MTC was positively correlated with receipt of antibiotics within three hours (r = 0.5452, p = 0.0070). Joint orthoplastic plans were documented in 89 % of patients (MTC range 30-95 %). Soft tissue cover was achieved within 72 h for 48 % (MTC range 5.23-89.39 %). Patients over 65 were significantly more likely to have a delay to MTC admission and prophylactic antibiotic administration. Mortality rate in this group was 6% vs 2 % in those under 65. The older cohort were twice as likely to require an amputation.

CONCLUSION

This is the largest cohort of open tibial injuries managed in the UK with wide variation in practice between centres demonstrated and better adherence to BOAST guidelines linked to reduced mortality in those aged 65 and over. The older cohort of patients also had higher rates of infection and amputation. It is unclear whether these poor outcomes are due to the pre-morbid physiological status of the patient or non-compliance to Standards. We present these data to highlight the need for improved adherence to Standards - the adoption of a scoring system provides a simple way to evidence this.

The integration of ortho-plastic limb salvage teams in the humanitarian response to violence-related open tibial fractures: evaluating outcomes in the Gaza Strip

BACKGROUND

Limb salvage by ortho-plastic teams is the standard protocol for treating open tibial fractures in high-income countries, but there's limited research on this in conflict settings like the Gaza Strip. This study assessed the clinical impact of gunshot-related open tibial fractures, compared patient management by orthopedic and ortho-plastic teams, and identified the risk factors for bone non-union in this context.

METHODS

A retrospective review of medical records was conducted on Gaza Strip patients with gunshot-induced-open tibial fractures from March 2018 to October 2020. Data included patient demographics, treatments, and outcomes, with at least one year of follow-up. Primary outcomes were union, non-union, infection, and amputation.

RESULTS

The study included 244 injured individuals, predominantly young adult males (99.2%) with nearly half (48.9%) having Gustilo-Anderson type IIIB fractures and more than half (66.8%) with over 1 cm of bone loss. Most patients required surgery, including rotational flaps and bone grafts with a median of 3 admissions and 9 surgeries. Ortho-plastic teams managed more severe muscle and skin injuries, cases with bone loss > 1 cm, and performed less debridement compared to other groups, though these differences were not statistically significant. Non-union occurred in 53% of the cases, with the ortho-plastic team having the highest rate at 63.6%. Infection rates were high (92.5%), but no significant differences in bone or infection outcomes were observed among the different groups. Logistic regression analysis identified bone loss > 1 cm, vascular injury, and the use of a definitive fixator at the first application as predictors of non-union.

CONCLUSIONS

This study highlights the severity and complexity of such injuries, emphasizing their significant impact on patients and the healthcare system. Ortho-plastic teams appeared to play a crucial role in managing severe cases. However, further research is still needed to enhance our understanding of how to effectively manage these injuries.

Comparing outcomes following direct admission and early transfer to specialized trauma centers in open tibial fracture treatment: a systematic review and meta-analysis

INTRODUCTION

Guidelines on the management of open tibia fractures recommend timely treatment in a limb reconstruction center which offer joint orthopedic-trauma and plastic surgery services. However, patient's transfer between centers remains inevitable. This review aims to evaluate the clinical outcomes and hospital factors for patients directly admitted and transferred patients to a limb-reconstruction center.

METHODS

A research protocol adhering to PRISMA standards was established. The search included databases like MEDLINE, EMBASE, and the Cochrane library up until March 2023. Nine articles met the inclusion criteria, focusing on open tibia fractures. Exclusion criteria were experimental studies, animal studies, and case reports. Outcomes of interest were operation and infection rates, nonunion, limb salvage, and the Enneking limb score.

RESULTS

The analysis involved data from 520 patients across nine studies published between 1990 and 2023, with the majority (83.8%) having Gustilo Anderson type III open tibia fractures. Directly admitted patients showed lower overall infection rates (RR 0.30; 95% CI 0.10-0.90; P = 0.03) and fewer deep infections (RR 0.39; 95% CI 0.22-0.68; P = 0.001) compared to transferred patients. Transferred patients experienced an average five-day delay in soft tissue closure and extended hospital stays by eight days. Patients transferred without initial surgical management underwent fewer total surgical procedures. The direct admission group displayed more favorable functional outcomes.

CONCLUSION

Low- to moderate-quality evidence indicates worse clinical outcomes for transferred patients compared to directly admitted patients. Early treatment in specialized limb reconstruction units is essential for improved results in the management of open tibia fractures.

A Prospective Comparative Study of Pre-debridement and Post-debridement Cultures in Open Fractures of the Extremities

Introduction Amputations and recurrent infections are two terrible outcomes of open fractures that can leave patients with permanent impairments. Rapid and effective treatment can protect patients from open fracture sequelae and the long-term financial burden these injuries frequently cause. Over 50% of open fractures are caused by high energy trauma, which most frequently happens in car accidents or severe falls. There hasn't been much research done on the first bacterial ecology of open fracture wounds in the Indian environment. Therefore, the need of the current assignment was to assess the effectiveness of pre-debridement and post-debridement culture in open fractures of the extremities. Methodology A prospective comparative study was carried out with 65 patients who were hospitalized from the OPD and Emergency departments at the R. L. Jalappa Hospital and Research Center. The time frame of study was between December 2020 and July 2022. Prior to the trial, each participant's written informed consent was obtained and strict protocol was followed in accordance with the Institutional Ethics Committee. Results Among the study participants, the majority of cases (26.15%) belonged to the 21-30 years of age group. A total of 14 participants belonged to the 41-50 years of age group. Out of the total, nine patients were aged less than 20 years. Out of the total, in pre-debridement culture the majority of cases had presence of growth of Staphylococcus aureus followed by Acinetobacter species, Enterobacter species and Pseudomonas species. Only six patients had growth of Klebsiella species. After debridement and treatment for bacterial infection, on subsequent culture examination, no growth was found among 61 patients. Although in four patients, there was presence of Pseudomonas species, Enterobacter species and Proteus microorganisms. Conclusion Although the validity of sequential cultures has been questioned in a number of investigations, this study has demonstrated that debridement cultures have a significant impact in postoperative infection. Debridement culture is therefore advised to offer information about the selection of antimicrobial medication, which when paired with a complete wound debridement will permit an early wound closure and better overall outcome functionally.

Bone union and mobility outcomes for reconstructed open tibial fractures: a plastic surgical experience from a major trauma center

Introduction

The goal in open tibial fracture management is to achieve a united tibia in an extremity that allows pain free mobilization. The objective of this study was to assess factors that lead to this functional outcome in lower limb reconstruction, from a plastic surgical perspective.

Materials and methods

The Plastic and Reconstructive Surgery lower limb database at a tertiary trauma hospital was searched for open tibial injuries from February 2015 to March 2020. The nature and severity of injury, timing and details of all operations including reconstructions were collected prospectively. Mobility including gait aids, pain, and complications were retrospectively collected. Union was assessed in two ways, depending on fracture location. Metaphyseal and diaphyseal tibial fractures were provided mRUST scores (union defined as RUST > 13) and epiphyseal tibial fractures were categorically classified as "united" or "non-union" by two independent radiologists.

Results

During the five-year study period there were 148 open leg injuries in the database. Twenty-one patients underwent a primary amputation due to severity of their initial injury. One hundred patients underwent primary limb salvage. Sixty-one patients in the limb salvage group achieved primary tibial union with a mean follow-up time of 19.4 months post injury. Twenty-three additional patients were confirmed to subsequently unite. Patient who achieved union were more likely to mobilise without gait aids.

Discussion

In this study definitive external fixation and soft tissue infection were both associated with higher rates of non-union. Longer times to soft tissue reconstruction was not associated with an increase in acute soft tissue complications. More importantly bone union, pain and mobility did not decline. After undertaking a primary limb salvage pathway for 100 patients, the ultimate tibial fracture union rate was 84% and the confirmed ambulation rate was 96%.

Enhanced recovery for acute open lower limb fracture 'fix and flap'

INTRODUCTION

Enhanced recovery (ER) aims to achieve earlier recovery, reduced hospital length of stay (LoS) whilst improving outcomes. Our ER protocol for acute lower-limb open fracture (ALLOFs) includes dangling at day 3 and mobilising fully weight-bearing from day 5. Our aims were to evaluate the outcomes of ALLOFs using our ER protocol for limb salvage, LoS following 'fix & flap', return to theatre, rate of successful flap salvage, flap failure and deep infection rates.

METHODS

An observational study of a prospectively maintained lower limb flap database from September 2020 to January 2023 was undertaken. Search criteria encompassed patients with a Gustilo IIIB/C injury and a free flap reconstruction. Exclusions were for local/perforator flaps, soft tissue injury only, fracture related/prosthetic joint infections, or chronic osteomyelitis cases.

RESULTS

161 patients were available for analysis, 126 male (78 %) and 35 female (22 %) with a median age of 40 years (12-79, interquartile range 30.0). 81 % of cases were high-energy injuries. For all patients, the median time to definitive fixation and soft tissue coverage from injury was 4 days (0-30, interquartile range 2). 18 cases (11.2 %) required return to theatre for flap exploration; 11 cases were successfully salvaged (61 %). Nine free flaps failed (5.4 %). The median total LoS from admission was 10 days (6 to 46, interquartile range 5), with a median LoS following definitive fixation and soft tissue coverage of 7 days (4 to 20, interquartile range 3). The median follow-up period was 18 months (12 to 38.2, interquartile range 9), with a deep infection rate of 6.5 %.

CONCLUSION

In isolated ALLOFs, our ER protocol is safe and effective in shortening the LoS. Our outcomes sit comfortably within acceptable ranges of contemporary literature for return to theatre, flap salvage/failure and deep infection. Our ER protocol actively involves our allied health professional colleagues early to facilitate discharge.

Reconstruction of soft tissue defect around knee with thoracodorsal artery perforator flap and muscle-sparing latissimus dorsi flap

INTRODUCTION

Around the knee reconstruction is challenging for reconstructive surgeons. Several methods have been proposed, including perforator and muscle flaps; however, all have advantages and disadvantages. As the success rate of free-flap surgery increases, reconstruction around the knee using this method is becoming increasingly popular. Nevertheless, there are no large-scale case reports in the previous literature using either a thoracodorsal artery perforator flap (latissimus dorsi (LD) perforator flap) or a muscle-sparing latissimus dorsi (msLD) flap for reconstruction around the knee. In this retrospective report, we describe our clinical experiences and present an algorithm regarding recipient vessel choice in free-flap reconstructive surgery of around the knee defects.

PATIENT AND METHODS

Fifty-six cases in which a flap from the lateral thoracic area was used to reconstruct an around the knee defect between January 2016 and March 2022 were reviewed. The patients were aged 18-87 years (mean, 52.13 years), and of the 56 patients, 36 were male and 20 were female. Injuries were caused by trauma, contracture, rheumatoid vasculitis, tumor, infection, burns, sunken deformity, and pressure sores. The 56 cases included 22 with a defect including the knee, 14 with a defect below the knee (7 of the primary below-knee amputation [BKA] and 7 of the secondary BKA), 9 involving the distal medial thigh, 8 involving the distal lateral thigh, 2 involving the popliteal area, and 1 involving the middle thigh. Most cases were reconstructed using a single LD perforator flap or msLD flap. Chimeric or supplementary flaps were used when extensive coverage or dead space obliteration was required. The average size of the defect area was 253.6 cm2 (range: 5 × 6-21 × 39 cm2 ).

RESULTS

In the cases, the recipient artery used included the following: descending genicular artery (23), superficial femoral artery (14), descending branch of the lateral circumflex femoral artery (14), anterior tibial artery (2), popliteal artery (2), and posterior tibial artery (1). The recipient vein included the greater saphenous vein (24), descending branch of the lateral circumflex femoral vein (14), superficial femoral vein (7), descending genicular vein (6), anterior tibial vein (2), popliteal vein (2), and posterior tibial vein (1). The average flap size was 281.8 cm2 (range: 4 × 8-35 × 19 cm2 ). All flaps survived; however, seven complications occurred, including 2 partial flap losses, 1 arterial insufficiency, 1 hematoma, 1 minor dehiscence, 1 donor-site graft loss, and 1 short BKA. Normal knee range of motion (121-140°) was observed in 34 patients and 16 showed varying degrees of limited range of motion. Motion was not observed in four patients who underwent knee fusion and could not be evaluated in two patients who underwent above-knee amputation. The mean follow-up duration was 24.6 months (range: 4-72 months).

CONCLUSION

The LD perforator flap is ideal for the reconstruction of around the knee defects because it enables a long pedicle, large flap, and chimeric design. The msLD flap is ideal because it enables strong stump support, dead-space obliteration, and infection control. Moreover, since the two flaps are distant from the knee, this method is advantageous in terms of postoperative rehabilitation and there is minimal donor-site morbidity due to the thin nature of the LD muscle. In addition, the flap can be elevated in three positions and the operation can be completed without positional changes in various recipient vessel locations. Based on our experience, we conclude that the LD flap has the potential to be used as widely as or in preference to the anterolateral thigh flap in the reconstruction of around the knee defects.

A deep surgical site infection risk score for patients with open tibial shaft fractures treated with intramedullary nail

OBJECTIVES

To identify deep infection risk factors in patients with open tibial shaft fractures and to develop a scoring algorithm to predict the baseline deep infection risk in this patient population.

METHODS

A retrospective cohort study conducted at a single academic trauma center identified patients with open tibial shaft fractures treated with intramedullary nail fixation from December 2006 to October 2020. The primary outcome was a deep surgical site infection requiring surgical debridement. The outcome was identified by Current Procedural Terminology codes and confirmed with a medical chart review documenting evidence of a tibial draining wound or sinus tract.

RESULTS

Deep surgical site infection occurred in 13% of patients (97/769). Factors that predicted deep surgical site infection were identified. Gustilo-Anderson type IIIB or IIIC was the strongest predictor with a 12-fold increase in the odds of deep infection (OR 11.8, p < 0.001). Additional factors included age >40 years (OR 1.7, p = 0.03), American Society of Anesthesiologists score ≥3 (OR 1.9, p < 0.01), Gustilo-Anderson type IIIA vs. type I or II (OR 2.8, p = 0.004), and gunshot wounds (OR 2.9, p = 0.02). The risk scoring model predicted patients who would develop an infection with an acceptable level of accuracy (AUC 0.79). The risk score categorized patients from a low probability of deep infection 2%-6% with <10 points to high risk (58%-69%) with >40 points.

CONCLUSIONS

This risk score model predicts deep postoperative infection in patients with open tibial shaft fractures treated with intramedullary nails. The ability to accurately estimate deep infection risk at the time of presentation might aid patient expectation management and allow clinicians to focus infection prevention strategies on the high-risk subset of this population.

Standardising the management of open extremity fractures: a scoping review of national guidelines

INTRODUCTION

Open extremity fractures can be life-changing events. Clinical guidelines on the management of these injuries aim to standardise the care of patients by presenting evidence-based recommendations. We performed a scoping systematic review to identify all national clinical practice guidelines published to date.

MATERIALS AND METHODS

A PRISMA-compliant scoping systematic review was designed to identify all national or federal guidelines for the management of open fractures, with no limitations for language or publication date. EMBASE and MEDLINE database were searched. Article screening and full-text review was performed in a blinded fashion in parallel by two authors.

RESULTS

Following elimination of duplicates, 376 individual publications were identified and reviewed. In total, 12 clinical guidelines were identified, authored by groups in the UK, USA, the Netherlands, Finland, and Malawi. Two of these focused exclusively on antibiotic prophylaxis and one on combat-related injuries, with the remaining nine presented wide-scope recommendations with significant content overlap.

DISCUSSION

Clinical practice guidelines serve clinicians in providing evidence-based and cost-effective care. We only identified one open fractures guideline developed in a low- or middle-income country, from Malawi. Even though the development of these guidelines can be time and resource intensive, the benefits may outweigh the costs by standardising the care offered to patients in different healthcare settings. International collaboration may be an alternative for adapting guidelines to match local resources and healthcare systems for use across national borders.

Implementing an orthoplastic treatment protocol for open tibia fractures reduces complication rates in tertiary trauma unit

INTRODUCTION

Open tibia fracture (OTF) causes a considerable increase in morbidity and risk for complications compared to closed fractures. The most significant OTF complication leading to morbidity is commonly considered to be fracture-related infection (FRI). In September 2016, Tampere University Hospital (TAUH) introduced a treatment protocol for OTFs based on the BOAST 4 guideline. The aim of this study is to investigate the outcomes before and after implementation of the OTF treatment protocol.

MATERIALS AND METHODS

A retrospective cohort study was conducted using handpicked data from the patient record databases of TAUH from May 1, 2007, to May 10, 2021. For patients with OTF, we collected descriptive information, known risk factors for FRI and nonunion, bony fixation method, possible soft tissue reconstruction method, information about the timing of internal fixation and soft tissue coverage, and timing of primary operation. As outcome measures, we collected information on FRI, reoperation due to non-union, flap failure, and secondary amputation. We then compared the incidence of complications before and after the implementation of the OTF treatment protocol at TAUH.

RESULTS

After predefined exclusions, a total of 203 patients with OTF were included. Of these, 141 were treated before and 62 after the implementation of the OTF treatment protocol. The FRI rate in the pre-protocol group was significantly higher compared to the protocol group (20.6% vs 1.6%, p = 0.0015). The incidence of reoperation due to nonunion was also significantly higher in the pre-protocol group (27.7% vs 9.7%, p = 0.0054). According to multivariable analysis, definitive fixation and soft tissue coverage performed in separate operations was an independent risk factor for both FRI and reoperation due to nonunion.

CONCLUSIONS

After implementation, the BOAST 4 based OTF treatment protocol reduced the rate of FRI and reoperation due to nonunion in patients with OTF treated at TAUH during the study period. We, therefore, recommend the implementation of such a treatment protocol in all major trauma centers treating patients with OTF. Furthermore, we also recommend the immediate referral of patients with complex OTF from hospitals lacking the preconditions to provide BOAST 4 based treatment to specialized centers.

Open fractures: Current treatment perspective

Severe open fractures present challenges to orthopaedic surgeons worldwide, with increased risks of significant complications. Although different global regions have different resources and systems, there continue to be many consistent approaches to open fracture care. Management of these complex injures continues to evolve in areas ranging from timing of initial operative debridement to the management of critical-sized bone defects. This review, compiled by representative members of the International Orthopaedic Trauma Association, focuses on several critical areas of open fracture management, including antibiotic administration, timing of debridement, bone loss, soft tissue management, and areas of need for future investigation.

Long-Term Follow-Up of Open Gustilo-Anderson IIIB Fractures Treated With an Adjuvant Local Antibiotic Hydroxyapatite Bio-Composite

Background Open fractures associated with significant tissue loss are complex and present challenges in management; they are associated with poor outcomes such as infection, non-union or amputation. This study aimed to evaluate outcomes of using an adjuvant local antibiotic hydroxyapatite bio-composite in the management of open Gustilo-Anderson IIIB fractures with up to eight years of follow-up. Methods This was a retrospective study. A total of 81 patients with Gustilo-Anderson IIIB fractures treated with "fix and flap" limb reconstruction with adjuvant local antibiotic therapy using a bio-composite carrier were reviewed. Results  The mean follow-up time for all the patients, at the time of data collection, was 55.8 months. Union was achieved in 96% with a limb salvage rate of 96.3% and a deep infection rate of 3.7%. Conclusion The use of local antibiotic therapy, together with a combined orthoplastic "fix and flap" approach for Gustilo-Anderson IIIB open fractures, was found to be associated with a very low rate of metalwork infection and high union and limb salvage rates. Future studies should include some functional and quality of life outcome measures to see the efficacy of this method.

What Is the Safe Window from Definitive Fixation to Flap Coverage in Type 3B Open Tibia Fractures? Supporting Plastics and Orthopaedics Alliance in Reducing Trauma Adverse Events (SPARTA)

OBJECTIVES

To delineate whether a "safe" window exists for timing from definitive fixation to definitive soft tissue coverage in the treatment of open tibial diaphyseal fractures requiring flap coverage.

DESIGN

International multicenter, retrospective comparative cohort study.

PATIENTS/PARTICIPANTS

Three hundred and seventy-three (n = 373) patients who sustained an open tibial shaft fracture requiring flap coverage.

METHODS

We evaluated the deep infection rates based on the timing between the definitive fixation and flap coverage. We determined several intervals of time from the day of definitive fixation (regardless of time from injury) and flap coverage. If performed on the same operative setting these were considered day 0. We evaluated coverage after 2 and 5 days from definitive fixation based on time versus infection rate curve inflection points. We adjusted for time to debridement and antibiotics within an hour.

MAIN OUTCOME MEASUREMENT

Deep infection after definitive fixation and flap coverage.

RESULTS

The mean age of the cohort was 42.4 years (SD = 18.2) and 270 were male (72.4%). The deep infection rate after flap coverage was 20.6% (77/373). Definitive fixation to flap coverage time of up to 2 days was not associated with an increased risk of infection [relative risk (RR) = 1.12; 95% confidence interval, 0.92-1.37; P = 0.26]. There was an increased risk of deep infection for more than 2 days (RR = 1.59) and >5 days (RR = 1.64).

CONCLUSION

This study observed a "safe" window of up to 2 days between definitive fixation and flap coverage in open tibial shaft fractures requiring coverage before a statistical increase in risk of deep infection rate occurred.

Clinical and Radiological Outcomes of Gustilo-Anderson Type IIIB Open Fractures in 125 Patients

INTRODUCTION

This study describes single-centre outcomes of Gustilo-Anderson type IIIB open fractures in relation to the current standards in the United Kingdom, which aim at performing skeletal fixation and soft tissue coverage at an early stage to salvage the limb and achieve bone union with a minimum infection rate.

METHODS

A total of 125 patients with 134 Gustilo-Anderson type IIIB open fractures, who had definitive skeletal fixation with soft tissue coverage between June 2013 and October 2021, were prospectively followed up and included in this study.

RESULTS

Initial debridement was performed within 12 hours from the time of injury for 62 (49.6%) patients and within 24 hours for 119 (95.2%) patients (mean= 12.4 hours). Definitive skeletal fixation and soft tissue coverage were achieved within 72 hours for 25 (20%) patients and within seven days for 71 (57%) patients (mean= 8.5 days). The mean follow-up duration was 43.3 (6-100) months, and the limb salvage rate was 97.1%. The occurrence of deep infections was associated with time from injury to initial debridement (p=0.049). Three patients (2.4%) developed deep (metalwork) infections, all three had their initial debridement performed within 12 hours from the time of injury. There was no association between time to definitive surgery and the development of deep infection (p=0.340). Bone union was achieved in 84.3% of patients following their primary surgery. Time to union was associated with fixation modality (p=0.002) and type of soft tissue coverage (p=0.028), and was negatively correlated with time to initial debridement (p=0.002, correlation coefficient -0.321). There was a 0.27-month decrease in time to union for every hour delay in time to debridement (p=0.021).

CONCLUSION

Delaying initial debridement or definitive fixation and soft tissue coverage didn't increase the rate of deep (metalwork) infections. The time to achieve bone union was negatively correlated with the time from injury to initial debridement. We advise prioritising surgical technique and availability of expertise over strict adherence to time thresholds of surgeries.

Open lower extremity fractures in the geriatric population

INTRODUCTION

Open fractures in the elderly are distinct compared to younger populations. The purpose of this study is to follow a series of open fractures of the lower extremity in the geriatric population to better prognosticate outcomes.

METHODS

We performed a retrospective chart review of patients over the age of 65 years old who were treated for an open, lower extremity fracture across two level I trauma medical systems. Patients were included if they had documented wound healing problems in the postoperative period, or 6 months of follow-up, or if they had a definitive radiographic outcome. Sixty-four patients were included of an average age of 76.23, of whom 73.4% were female.

RESULTS

The fracture types were midshaft femur in 3, distal femur in 9, patella in 2, proximal tibia in 3, proximal fibula in 1, midshaft tibia in 14, distil tibia in 8, ankle in 23, and talar neck/calcaneus in 1. Forty-two fractures were the result of low energy mechanism and 22 fractures were from high energy mechanism. Fourteen fractures were type 1, 32 were type 2, 11 were type 3A, 6 were type 3B, and 1 was type 3C. At final follow-up, 13 wounds were well healed, 39 wounds were healed following a delay of more than 6 weeks to achieve healing, 3 were infected, 3 had been treated with amputation, 2 had chronic ulceration, 2 with active draining, and 2 had draining sinuses.

DISCUSSION

Open lower extremity fractures are serious injuries with high rates of morbidity. Such risks are even higher in the geriatric population, particularly with regard to wound healing. This study provides important prognostic information in counseling geriatric patient with an open lower extremity fracture, as well as informs treatment in terms of wound surveillance and care in the postoperative period.

Orthoplastic Treatment of Open Lower-Limb Fractures Improves Outcomes: A 12-Year Review

BACKGROUND

The British Orthopaedic Association Standards for Orthopaedics and Trauma 4 (BOAST 4) inform the management of open lower-limb fractures. The authors conducted repeated reviews of performance against these standards over a 12-year period. This latest iteration has shown further improvements in outcomes concomitant with changes in service delivery.

METHODS

Data on Gustilo-Anderson grade IIIB or IIIC open lower-limb fractures were collected from a prospectively constructed departmental database and analyzed using Excel. Outcomes assessed included time to stabilization, time to definitive soft-tissue coverage, and deep infection rates.

RESULTS

A total of 69% of patients in our cohort received care that aligned with BOAST 4 guidelines. Median time to stabilization was 14.2 hours and to soft-tissue coverage was 47 hours, with 71% of cases compliant with BOAST 4 guidelines. The overall deep infection rate was 6.5% in our cohort. There was a significantly lower deep infection rate in BOAST 4-compliant cases (2%) versus noncompliant cases (16%), respectively (P = 0.05). A total of 41 of 61 patients had fixation and soft-tissue coverage in a single operation (fix and flap), eight had staged operations, and 12 required local flap closure. There was no significant difference in deep infection rates among these approaches.

CONCLUSIONS

Compliance with the BOAST 4 guidelines and time to definitive soft-tissue coverage have improved at our center since the last review. Deep infection rates were significantly lower in BOAST 4-compliant cases, further validating this approach. The fix and flap technique was introduced during the study period and reduces operative burden for patients. These results support a joint orthoplastic approach as the optimal management for these complex injuries.

Clinical effectiveness of the Ganga Hospital Open Injury Severity Score for limb salvage versus amputation in patients with complex limb injuries : a systematic review and meta-analysis

AIMS

Clinical management of open fractures is challenging and frequently requires complex reconstruction procedures. The Gustilo-Anderson classification lacks uniform interpretation, has poor interobserver reliability, and fails to account for injuries to musculotendinous units and bone. The Ganga Hospital Open Injury Severity Score (GHOISS) was designed to address these concerns. The major aim of this review was to ascertain the evidence available on accuracy of the GHOISS in predicting successful limb salvage in patients with mangled limbs.

METHODS

We searched electronic data bases including PubMed, CENTRAL, EMBASE, CINAHL, Scopus, and Web of Science to identify studies that employed the GHOISS risk tool in managing complex limb injuries published from April 2006, when the score was introduced, until April 2021. Primary outcome was the measured sensitivity and specificity of the GHOISS risk tool for predicting amputation at a specified threshold score. Secondary outcomes included length of stay, need for plastic surgery, deep infection rate, time to fracture union, and functional outcome measures. Diagnostic test accuracy meta-analysis was performed using a random effects bivariate binomial model.

RESULTS

We identified 1,304 records, of which six prospective cohort studies and two retrospective cohort studies evaluating a total of 788 patients were deemed eligible for inclusion. A diagnostic test meta-analysis conducted on five cohort studies, with 474 participants, showed that GHOISS at a threshold score of 14 has a pooled sensitivity of 93.4% (95% confidence interval (CI) 78.4 to 98.2) and a specificity of 95% (95% CI 88.7 to 97.9) for predicting primary or secondary amputations in people with complex lower limb injuries.

CONCLUSION

GHOISS is highly accurate in predicting success of limb salvage, and can inform management and predict secondary outcomes. However, there is a need for high-quality multicentre trials to confirm these findings and investigate the effectiveness of the score in children, and in predicting secondary amputations.Cite this article: Bone Joint J 2023;105-B(1):21-28.

Synchronous circular frame stabilisation and microsurgical soft tissue reconstruction for open lower limb fractures-A cost analysis and description of the surgical technique

INTRODUCTION

Current surgical paradigms for ortho-plastic management of IIIB open tibial fractures make compromises. Often, definitive circular frame stabilisation is delayed until the soft tissue envelope is secure to allow access for further soft tissue reconstruction if required. This delay has potential clinical and cost implications. A previous study showed acute circular frame stabilisation performed concurrently or before soft tissue reconstruction was feasible without additional soft tissue reconstruction problems. This study examines potential resource savings using this approach.

METHODS

All open tibial fractures managed by circular fixator and microsurgical soft tissue reconstruction between April 2015 and June 2019 were identified from a prospectively maintained database. Those receiving circular frame stabilisation with synchronous microsurgical soft tissue reconstruction were considered cases; those in whom the frame stabilisation was delayed were controls. Cost data were derived from the Patient Level Information and Costing System. Salvage cases and those with incomplete treatment were excluded.

RESULTS

Nine cases and 25 controls were evaluated. No statistically significant difference was observed between groups in terms of age, sex, injury severity score, time to debridement, time to coverage, length of follow up, or time to union. Median length of stay was 13.3 and 19.7 days for cases and controls respectively (p<0.01). Cases required fewer procedures (2.3) compared to controls (4.5) (p<0.001). The cost of care was less for cases (£25,527) than controls (£32,952) (p <0.05). No cases returned to theatre with flap failure or flap compromise. Complications were similar between groups.

CONCLUSION

In suitable patients, synchronous circular frame stabilisation and microsurgical soft tissue reconstruction is a safe, clinically effective, and cost-saving option.

Patterns of Head and Neck Injuries in Urban India: A Multicenter Study

Objective

The pattern of head and neck injuries has been well studied in high-income countries, but the data are limited in low- and middle-income countries, which are disproportionately affected by trauma. We examined a prospective multicenter database to describe patterns and outcomes of head and neck injuries in urban India.

Study Design

Retrospective review of trauma registry.

Setting

Four tertiary public hospitals in Mumbai, Delhi, Kolkata.

Methods

We identified patients with isolated head and neck injuries using International Classification of Diseases, 10th Revision (ICD-10) codes and excluded those with traumatic brain and/or ophthalmic injuries and injuries in other body regions.

Results

Our cohort included 171 patients. Most were males (80.7%) and adults aged 18 to 55 years (60.2%). Falls (36.8%) and road traffic accidents (36.3%) were the 2 predominant mechanisms of injury. Overall, 35.7% required intensive care unit (ICU) admission, and 11.7% died. More than 20% of patients were diagnosed with “unspecified injury of neck.” Those with the diagnosis had a higher ICU admission rate (51.4% vs 31.3%, P = .025) and mortality rate (27.0% vs 7.5%, P = .001) than those without the diagnosis.

Conclusion

Isolated head and neck injuries are not highly prevalent among Indian trauma patients admitted to urban tertiary hospitals but are associated with high mortality. Over a fifth of patients were diagnosed with “unspecified injury of neck,” which is associated with more severe clinical outcomes. Exactly what this diagnosis entails and encompasses remains unclear.

Increased open fracture complications following pediatric all-terrain vehicle accidents

BACKGROUND

ATV (All-Terrain Vehicle) related open fractures are often high energy and may be highly contaminated. We asked whether they were more complicated than other open fractures in pediatric patients.

METHODS

A retrospective chart review was performed comparing ATV associated open fractures to open fractures sustained in non-ATV related accidents. 97 pediatric open fractures from 2015 to 2021 were identified based on ICD-10 codes. Of these fractures, 62 were non-ATV related and 35 were ATV related. Charts were reviewed to collect basic demographics, fracture pattern, Gustilo-Anderson classification, procedures performed, operative findings, and complications.

RESULTS

Our cohort was predominantly male (71% in the ATV group and 76% in the non-ATV group). White race was more common in both the ATV (28 (80%)) and non-ATV (50(78%)) groups. The distribution of AO/OTA fractures was significantly different (p = 0.046), with humerus fractures being more common in the ATV group (8 (22%)) vs. non-ATV group (6 (9.3%)). The ATV group had a higher proportion of more severe type II and III open fractures with 77.1% (n = 27), versus 56% (n = 35) in the non-ATV group (p = 0.020).. Revision and reoperation were more likely in the ATV group (16 (23%)) vs. the non-ATV group (12 (15%)), as was malunion (ATV group 3 (4.3%) Vs. non-ATV 0 (0%)).

CONCLUSION

Open fractures resulting from ATV injuries tend to be more complex and have higher rates of revision and malunion. This information supports the large body of evidence on the dangers of ATVs to children and can help guide expectations of both clinicians and family members of patients presenting with these injuries.

The Open-Fracture Patient Evaluation Nationwide (OPEN) study : epidemiology of open fracture care in the UK

AIMS

Understanding of open fracture management is skewed due to reliance on small-number lower limb, specialist unit reports and large, unfocused registry data collections. To address this, we carried out the Open Fracture Patient Evaluation Nationwide (OPEN) study, and report the demographic details and the initial steps of care for patients admitted with open fractures in the UK.

METHODS

Any patient admitted to hospital with an open fracture between 1 June 2021 and 30 September 2021 was included, excluding phalanges and isolated hand injuries. Institutional information governance approval was obtained at the lead site and all data entered using Research Electronic Data Capture. Demographic details, injury, fracture classification, and patient dispersal were detailed.

RESULTS

In total, 1,175 patients (median age 47 years (interquartile range (IQR) 29 to 65), 61.0% male (n = 717)) were admitted across 51 sites. A total of 546 patients (47.1%) were employed, 5.4% (n = 63) were diabetic, and 28.8% (n = 335) were smokers. In total, 29.0% of patients (n = 341) had more than one injury and 4.8% (n = 56) had two or more open fractures, while 51.3% of fractures (n = 637) occurred in the lower leg. Fractures sustained in vehicle incidents and collisions are common (38.8%; n = 455) and typically seen in younger patients. A simple fall (35.0%; n = 410) is common in older people. Overall, 69.8% (n = 786) of patients were admitted directly to an orthoplastic centre, 23.0% (n = 259) were transferred to an orthoplastic centre after initial management elsewhere, and 7.2% were managed outwith specialist units (n = 81).

CONCLUSION

This study describes the epidemiology of open fractures in the UK. For a decade, orthopaedic surgeons have been practicing in a guideline-driven, network system without understanding the patient features, injury characteristics, or dispersal processes of the wider population. This work will inform care pathways as the UK looks to the future of trauma networks and guidelines, and how to optimize care for patients with open fractures.Cite this article: Bone Jt Open 2022;3(10):746-752.

Soft-Tissue Reconstruction of Complicated Total Ankle Arthroplasty

BACKGROUND

Total ankle arthroplasty (TAA) is a popular modality to treat end-stage arthritis or internal ankle derangement. Unfortunately, failure rates remain undesirably high, with severe complications, including prosthesis failure, ankle fusion, and amputation. The importance of a stable soft-tissue envelope for coverage of implant compromise has been previously described, but the predictive factors for successful salvage of complicated TAA remain poorly understood.

METHODS

A retrospective review was conducted of patients requiring soft-tissue reconstruction following TAA wound complications. Patient demographics, history, microbiological data, reconstructive approach, and outcomes data were collected. Statistical analysis was used to abstract factors associated with unsuccessful prosthetic salvage.

RESULTS

In all, 13 patients met inclusion criteria: 8 (61.5%) achieved prosthetic salvage, and 5 (38.5%) failed. The majority (90.9%) of patients presented with infected joints. Reconstructive techniques included skin grafts, dermal substitutes, locoregional flaps, and free tissue transfer. Successful prosthetic salvage was associated with shorter time intervals between wound diagnosis and index reconstructive surgical intervention (median: 20 days for salvage vs 804 days for failure; P = .014). Additionally, salvage was associated with reduced time from the index orthopaedic/podiatric surgical intervention to the index reconstructive surgery procedure (12 vs 727 days; P = .027).

CONCLUSION

The prognosis of complicated TAA requiring soft-tissue reconstruction remains poor, especially in patients who present with infected joints. Several reconstructive techniques, ranging from simple skin grafts to complex free tissue transfers, can be used successfully. Early intervention to achieve soft-tissue coverage is crucial in maximizing salvage rates in the setting of complicated and infected TAA.

External Locking Plate Fixation for Femoral Subtrochanteric Fractures

Introduction

Internal fixation is the treatment of choice for subtrochanteric fractures in most conditions. However, it may be an unsuitable procedure for patients with poor health status, osteomyelitis, and surrounding soft tissue compromise. This study aimed to ascertain the viability and reliability of using external locking plate fixation for these difficult cases.

Methods

Eleven patients with femoral subtrochanteric fractures who received external locking plate fixation in our institute from January 2014 to December 2019 were enrolled in our study. The bone union time, wound complication, alignment, and necessity for narcotic agents were evaluated.

Results

The average length of follow-up was 17.5 months (range, 14-26 months). The mean time for bone union was 17.7 weeks (range, 15-21 weeks). The indications included poor health condition, soft tissue compromise, and post-operative osteomyelitis. Pin tract infection was noted in two patients who were treated successfully with oral antibiotics administration and removal of the involved screws. Osseous union with varus deformity <10° was achieved in all patients except one. Three patients required an orally administered pain killer at the final visit. The average Harris Hip Score at one year post-operatively was 66.6 (range, 49-80).

Conclusions

Although the current study only involved 11 patients, we believe that our method may serve as a valuable alternative for the treatment of a femoral subtrochanteric fracture in selected cases.

Orthoplastic Reconstruction of Type IIIB Open Tibial Shaft Fractures Using Debrided, Devitalized Cortical Segments: Health-Related Quality-of-Life Outcomes

OBJECTIVE

To determine health-related quality of life (HRQoL) in patients who sustained type IIIB open tibial diaphyseal (OTA/AO-42) fractures and underwent orthoplastic reconstruction using mechanically relevant devitalized bone (ORDB) versus those who did not require the use of devitalized bone as part of their orthoplastic reconstruction.

DESIGN

Consecutive cohort study.

PATIENTS/PARTICIPANTS

The study included 74 patients who sustained a type IIIB open tibial diaphyseal fracture requiring orthoplastic reconstruction over a 4-year period in a major trauma center. All patients underwent a two-stage orthoplastic reconstruction protocol, with the second stage consisting of definitive fixation and flap coverage (free fascial anterolateral thigh flap) in a single sitting. Patients were contacted at a minimum of 30 months to measure HRQoL.

INTERVENTION

Patients requiring ORDB versus those who did not require the use of devitalized bone as part of their orthoplastic reconstruction.

MAIN OUTCOME MEASUREMENTS

The primary outcome measure was HRQoL ascertained using Euro-Qol (EQ)-5D and Short-Form (SF)-36 scores.

RESULTS

Thirty (n = 30) patients underwent ORDB with the remaining 44 not requiring devitalized bone as part of their reconstruction. The median age was 46.5 years [interquartile range (IQR) 29.0], with a median follow-up of 3.8 years (IQR 1.5). The median cohort EQ-5D was 0.743 (IQR 0.222), ORDB 0.743 (IQR 0.195) versus non-ORDB 0.748 (IQR 0.285), P = 0.71. The median physical component SF-36 score was 80 (IQR 50), ORDB 80 (IQR 34.5) versus non-ORDB 77.5 (IQR 58.75), P = 0.72. The median mental component SF-36 score was 80 (IQR 28), ORDB 80 (IQR 21) versus non-ORDB 80 (IQR 36), P = 0.29.

CONCLUSIONS

In patients who sustained a type IIIB open tibial shaft fracture and who underwent a 2-stage orthoplastic reconstruction, ORDB does not seem to be associated with inferior health-related quality of life based on EQ-5D or SF-36 scores. The results of this approach should be considered within the strict combined orthoplastic approach in the study unit.

Management of soft-tissue coverage of open tibia fractures in Latin America: Techniques, timing, and resources

PURPOSE

This study examined soft-tissue coverage techniques of open tibia fractures, described soft-tissue treatment patterns across income groups, and determined resource accessibility and availability in Latin America.

METHODS

A 36-question survey was distributed to orthopaedic surgeons in Latin America through two networks: national orthopaedic societies and the Asociación de Cirujanos Traumatólogos de las Américas (ACTUAR). Demographic information was collected, and responses were stratified by income groups: high-income countries (HICs) and middle-income countries (MICs).

RESULTS

The survey was completed by 469 orthopaedic surgeons, representing 19 countries in Latin America (2 HICs and 17 MICs). Most respondents were male (89%), completed residency training (96%), and were fellowship-trained (71%). Only 44% of the respondents had received soft-tissue training. Respondents (77%) reported a strong interest in attending a soft-tissue training course. Plastic surgeons were more commonly the primary providers for Gustilo Anderson (GA) Type IIIB injuries in HICs than in MICs (100% vs. 47%, p<0.01) and plastic surgeons were more available (<24 h of patient presentation to the hospital) in HICs than MICs (63% vs. 26%, p = 0.05), demonstrating statistically significant differences. In addition, respondents in HICs performed free flaps more commonly than in MICs for proximal third (55% vs. 10%, p<0.01), middle third (36% vs. 9%, p = 0.02), and distal third (55% vs. 10%, p<0.01) lower extremity wounds. Negative Pressure Wound Therapy (NPWT or Wound VAC) was the only resource available to more than half of the respondents. Though not statistically significant, surgeons reported having more access to plastic surgeons at their institutions in HICs than MICs (91% vs. 62%, p = 0.12) and performed microsurgical flaps more commonly at their respective institutions (73% vs. 42%, p = 0.06).

CONCLUSIONS

The study demonstrated that most orthopaedic surgeons in Latin America have received no soft-tissue training, HICs and MICs have differences in access to plastic surgeons and expectations for flap type and timing to definitive coverage, and most respondents had limited access to necessary soft-tissue surgical resources. Further investigation into differences in the clinical outcomes related to soft-tissue coverage methods and protocols can provide additional insight into the importance of timing and access to specialists.

Management of open elbow fractures: experiences and outcomes from a UK major trauma center

HYPOTHESIS AND BACKGROUND

Open fractures about the elbow are an infrequent but complex injury with limited existing literature. The aims of the study were to review the treatment strategies of open elbows fractures, functional outcome and complication rates associated with the injury, and correlate the outcome with the topography of the fracture.

METHODS

Patients (n = 21) with open elbow fractures injuries over a 2-year period were analyzed. They were assessed regarding the orthoplastic characteristics of their injury as well any other associated injuries. Outcomes were assessed objectively (achievement of bony union, range of movement, infection status, need for further procedures) and subjectively (Oxford Elbow Score, EQ-5D, EQ-VAS).

RESULTS

The commonest grade of open injury was grade 3 (43%). Associated orthopedic injuries were present in 62% and associated system injuries in 57%. Almost half of the patients were noted to have had a significantly increased presenting mortality risk as per Injury Severity Score assessment. Mean time to first wound débridement was 31 hours. There were no cases of deep or chronic infection. Complete bony union was noted in 85% of patients, and 48% of patients required removal of metalwork. Subgroup analysis of the cohort by fracture topography (single unipolar elbow bone injury vs. multiple elbow bony injuries) demonstrated no significant difference (P > .05) regarding rate of complication or final Oxford Elbow Score, EQ-5D or EQ-VAS. Patients with injuries that involved the distal humerus had the highest rate for further procedures (P < .05). The average Oxford Elbow Score, EQ-5D, and EQ-VAS scores for the whole cohort at final follow-up were 37.4, 0.54, and 62.18, respectively.

DISCUSSION

Open elbow injuries are usually from high-energy trauma and often combined with other significant injuries. As a result, the timelines to elbow surgery were often delayed. However, this did not impact the local infection rates nor did it necessitate further surgery, but made achieving all British Orthopaedic Association Standards for Trauma targets difficult. Chronic infection was not an issue in this cohort. Subgroup analysis indicates open distal humerus fractures carry the highest risk for further procedures. This is most commonly in the form of removal of metalwork and fibrinolysis. End outcomes for patients with open elbow fractures can be positive, despite the notable presenting Injury Severity Score. A subspecialist elbow and orthoplastic approach whenever possible is advocated.

One-stage combined "fix and flap" approach for complex open Gustilo-Anderson IIIB lower limbs fractures: a prospective review of 102 cases

BACKGROUND

Management of open fractures is challenging and requires a multidisciplinary team approach. This study aims to evaluate outcomes of open Gustilo-Anderson IIIB fractures managed at a single Ortho-Plastic centre following One-stage "Fix and Flap" approach.

METHODS

Prospective data review for patients presenting with Gustilo-Anderson IIIB Fractures to our centre and managed with one-stage "Fix and Flap" approach. Postoperative outcomes are presented only for the patients who had a minimum of 12 months postoperative follow-up.

RESULTS

120 patients were included (83 males and 37 females). Mean age was 43 years (10-96). Tibia diaphysis was the most common site of injury (60%). 55.9% of injuries were road traffic accidents (RTA). 102 out of 120 patients had a minimum of 12 months follow-up (mean follow-up duration 25 months). Meantime from injury until definitive surgery was 7.71 days. Primary union achieved in 86.73%. Delayed union was encountered in 10.20%. 3.06% of patients had non-union. Limb salvage rate was 97.05% and Deep infection rate was only 0.98%.

CONCLUSION

Our results showed that low infection rate, high limb salvage rate, and high union rate can be achieved in these complex injuries with meticulous technique, combined Ortho-Plastic (Fix and Flap) approach, and MDT input.

A Case of Reconstruction of an Open Tibial Fracture (Gustilo-Anderson Type IIIB) With Severe Skin and Bone Loss Using Corticocancellous Bone Plugs From the Iliac Crest and an Ilizarov Frame

Gustilo-Anderson type IIIB fractures include open fractures with extensive soft tissue injury with periosteal stripping and bony exposure. They are usually associated with massive contamination and can be challenging even for experienced surgeons. A multidisciplinary approach among plastic and trauma surgeons is often required. We present a case of a 58-year-old man with a type IIIB open tibial fracture initially managed with a bridging external fixation and primary skin closure using a fasciocutaneous sural flap. Two months later, there was no evidence of fracture healing and an Ilizarov device was applied with corticotomy at the proximal tibial metaphysis, which was modified five months later without changing the frame, placing autogenous iliac bone plugs at the fracture site using the mosaicplasty harvesting technique. Seven months after its initial placement, the Ilizarov device was removed allowing full weight-bearing, with callus formation present at 10-month follow-up. Finally, the patient showed acceptable radiological and functional outcomes after a follow-up of two years. The Ilizarov method should be considered as a therapeutic option for complicated open fractures with severe bone and skin loss. The patient should be fully informed about the complexity of these fractures and the necessity of multiple surgical interventions in order to have realistic expectations.

Gastrocnemius pedicled muscle flap for knee and upper tibia soft tissue reconstruction. A useful tool for the orthopaedic surgeon

Soft tissue defect coverage has always been a challenge for the orthopaedic surgeon. Over the last decades the surgery of flaps has completely changed the prognosis for large defects. The purpose of this study is to retrospectively review our experience with the gastrocnemius muscle as pedicled local flaps for reconstruction of knee and upper third of the tibia soft tissue defects. Twenty-seven patients underwent reconstruction of soft tissue defects around the knee using pedicled gastrocnemius muscle flaps. There were eighteen men and nine women ranged in with a mean age of 50.3 years. Medial gastrocnemius was used in 21 cases, and lateral gastrocnemius in 5 cases. In one patient, soleus and medial gastrocnemius were transferred simultaneously. All but one had at the same time split thickness skin graft for coverage of the muscle. All muscle flaps transferred were successful. There were no complications and all flaps survived completely without vascular compromise, satisfactory coverage of the defect, and good primary wound healing. There has been no recurrence of osteomyelitis. The donor sites healed perfectly with no remarkable resultant functional disability. A mean follow-up of 4.4 years revealed acceptable cosmetic results with high patient satisfaction. Our results indicate that the gastrocnemius muscle transfer is a useful technique for coverage of soft tissue defects in the upper tibia and around the knee in our orthopaedic practice. It is a reliable option for the coverage of exposed bone, the filling up of deep cavities and the treatment of bone infection. The principal advantage of a muscle flap is to bring a real blood supply to the recipient site and to improve the trophicity of the surrounding tissues. The pedicled muscle flap is our preference for the management of soft tissue defects around the knee, when no other procedure, apart from free flap is suitable. The pedicle flap is easier, quicker and with less complications than a free flap. Orthopaedic surgery has gained much from the use of island flap, however, it requires knowledge of the vascular anatomy and its variations promoted through cadaveric dissections and flap dissection courses.

Open tibia/fibula in the elderly: A retrospective cohort study

The incidence of open tibia/fibula fractures in the elderly is increasing, but current national guidelines focus on the aggressive treatment of high-energy injuries in younger patients. There is conflicting evidence regarding whether older age affects treatment provision and outcomes in open fractures. The aim of this study was to determine if elderly patients are sustaining a different injury to younger patients and how their treatment and outcomes differ. This may have implications for future guidelines and verify their application in the elderly. In this retrospective single centre cohort study (December 2015-July 2018), we compared the injury characteristics, operative management and outcomes of elderly (≥65 years) and younger (18-65 years) patients with open tibia/fibula fractures. An extended cohort examined free flap reconstruction. In total, 157 patients were included. High-energy injuries were commoner in younger patients (88% vs 37%; p<0.001). Most were Gustilo-Anderson IIIb in both age groups. Elderly patients waited longer until debridement (21:19 vs 19:00 h) and had longer inpatient stays (23 vs 15 days). There was no difference in time to antibiotics, operative approach or post-operative complications. Despite the low-energy nature of elderly patients' injuries, the severity of soft tissue insult was equivalent to younger patients with high-energy injuries. Our data suggest that age and co-morbidities should not prohibit lower limb reconstruction. The current application of generic guidelines appears suitable in the elderly, particularly in the acute management. We suggest current management pathways and targets be reviewed to reflect the greater need for peri-operative optimisation and rehabilitation in elderly patients.

High-Grade Limbs Open Fractures: Time to Find Milestones in the Emergency Setting

(1) Background: The Gustilo–Anderson (G/A) grading system is a universally accepted tool used to classify high-grade limb open fractures. The purpose of this study is to find early independent predictors of amputation in emergency settings. (2) Methods: A retrospective analysis involving patients treated at our center between 2010 and 2016 was conducted. Patients with at least one G/A grade III fracture or post-traumatic amputation were included. Three groups were identified: G/A IIIA (A group), G/A IIIB-C (BC group), and Amputation group (AMP group). Each group was further divided into two subgroups considering timing of coverage (early vs. delayed). Univariate and multivariate logistic regression models were developed to identify independent predictors of the limb’s outcome. (3) Results: One-hundred-six patients with G/A III A-B-C fractures or amputation of the affected limb were selected from the Niguarda Hospital Trauma Registry. The patients were divided into the A group (26), BC group (66), and AMP group (14). The rate of infectious complications following early or delayed coverage was evaluated: A group, 9.1% vs. 66.7% (p > 0.05); BC group, 32% vs. 63.6% (p = 0.03); and AMP group, 22% vs. 18.5% (p > 0.05). After further recategorization, the BC subgroups were analyzed: multivariate logistic regression model identified systolic blood pressure (SBP) <90 mmHg (p = 0.03) and Mangled Extremity Severity Score MESS ≥ 7 (p = 0.001) were determined to be independent predictors of limb amputation. (4) Conclusion: MESS and SBP serve as predictors of amputation. Based on the results, we propose a new management algorithm for mangled extremities. Early coverage is related to lower rates of infectious complications. Referral to high-volume centers with specific expertise is mandatory to guarantee the best results.

Institutional Experience and Orthoplastic Collaboration Associated with Improved Flap-based Limb Salvage Outcomes

BACKGROUND

Flap-based limb salvage surgery balances the morbidity and complexity of soft tissue transfer against the potential benefit of preserving a functional limb when faced with a traumatized extremity with composite tissue injury. These composite tissue injuries are well suited for multidisciplinary management between orthopaedic and plastic surgeons. Thus, it makes intuitive sense that a collaborative, orthoplastic approach to flap-based limb salvage surgery can result in improved outcomes with decreased risk of flap failure and other complications, raising the question of whether this orthoplastic team approach should be the new standard of care in limb salvage surgery.

QUESTIONS/PURPOSES

(1) Is there an association between increased annual institutional volume and perioperative complications to include free and local flap failure (substantial flap viability loss necessitating return to the operating room for debridement of a major portion or all of the flap or amputation)? (2) Is an integrated orthoplastic collaborative approach to managing combat-related traumatic injuries of the extremities individually associated with a decreased risk of flap failure and overall flap-related complications? (3) What other factors, such as location of injury, injury severity score, and initial inpatient length of stay, were associated with flap necrosis and flap-related complications?

METHODS

We performed a retrospective review of the electronic medical records of all patients who underwent flap-based limb salvage for combat-related extremity trauma in the United States Military Health System's National Capital Region between January 1, 2003 and December 31, 2012. In total, 307 patients underwent 330 flap procedures. Of the 330 flaps, 59% (195) were local or pedicled flaps and 41% (135) were free flaps. Patients were primarily male (99% [303]), with a median (interquartile range) age of 24 years old (IQR 21 to 29), and 87% (267 of 307) of injuries were sustained from a blast mechanism. We collected data on patient demographics, annual case volume involving flap coverage of extremities, mechanism of injury, flap characteristics, perioperative complications, flap failure, flap revision, isolated orthopaedic management versus an integrated orthoplastic approach, and other salvage procedures. For the purposes of this study, orthoplastic management refers to operative management of flap coverage with microvascular surgeons present for soft tissue transfer after initial debridement and fixation by orthopaedic surgery. The orthoplastic management was implemented on a case-by-case basis based on individual injury characteristics and the surgeon's discretion with no formal starting point. When implemented, the orthoplastic team consisted of an orthopaedic surgeon and microvascular-trained hand surgeons and/or plastic surgeons. In all, 77% (254 of 330) of flaps were performed using this model. We considered perioperative flap complications as any complication (such as infection, hematoma, dehiscence, congestion, or necrosis) resulting in return to the operating room for re-evaluation, correction, or partial debridement of the flap. We defined flap failure as a return to the operating room for debridement of a major portion of the flap or amputation secondary to complete or near-complete loss of flap viability. Of the flap procedures, 12% (40 of 330) were classified as a failure and 14% (46 of 330) experienced complications necessitating return to the operating room. Over the study period, free flaps were not more likely to fail than pedicled flaps (11% versus 13%; p = 0.52) or have complications necessitating additional procedures (14% versus 16%; p = 0.65).

RESULTS

Our multiple linear regression model demonstrated that an increased number of free flaps performed in our institution annually in any given year was associated with a lower likelihood of failure per case (r = -0.17; p = 0.03) and lower likelihood of reoperation for each flap (r = -0.34; p < 0.001), after adjusting for injury severity and team type (orthoplastic or orthopaedic only). We observed a similar relationship for pedicled flaps, with increased annual case volume associated with a decreased risk of flap failure and reoperation per case after adjusting for injury severity and team type (r = -0.21; p = 0.003 and r = -0.22; p < 0.001, respectively). Employment of a collaborative orthoplastic team approach was associated with decreased flap failures (odds ratio 0.4 [95% confidence interval 0.2 to 0.9]; p = 0.02). Factors associated with flap failure included a lower extremity flap (OR 2.7 [95% CI 1.3 to 6.2]; p = 0.01) and use of muscle flaps (OR 2.3 [95% CI 1.1 to 5.3]; p = 0.02).

CONCLUSION

Although prior reports of combat-related extremity trauma have described greater salvage success with the use of pedicled flaps, these reports are biased by institutional inexperience with free tissue transfer, the lack of a coordinated multiservice effort, and severity of injury bias (the most severe injuries often result in free tissue transfer). Our institutional experience, alongside a growing body of literature regarding complex extremity trauma in the civilian setting, suggest a benefit to free tissue coverage to treat complex extremity trauma with adequate practice volume and collaboration. We demonstrated that flap failure and flap-related complications are inversely associated with institutional experience regardless of flap type. Additionally, a collaborative orthoplastic approach was associated with decreased flap failures. However, these results must be interpreted with consideration for potential confounding between the increased case volume coinciding with more frequent collaboration between orthopaedic and plastic surgeons. Given these findings, consideration of an orthoplastic approach at high-volume institutions to address soft tissue coverage in complex extremity trauma may lead to decreased flap failure rates.

Protocol for a prospective cohort study of open tibia fractures in Malawi with a nested implementation of open fracture guidelines

Background: Road traffic injury (RTI) is the largest cause of death amongst 15–39-year-old people worldwide, and the burden of injuries such as open tibia fractures are rapidly increasing in Malawi. This study aims to investigate disability and economic outcomes of people with open tibia fractures in Malawi and improve these with locally delivered implementation of open fracture guidelines. Methods: This is a prospective cohort study describing function, quality of life and economic burden of open tibia fractures in Malawi. In total, 160 participants will be recruited across six centres and will be followed-up with face-to-face interviews at six weeks, three months, six months and one year following injury. The primary outcome will be function at one year measured by the short musculoskeletal functional assessment (SMFA) score. Secondary outcomes will include quality of life measured by EuroQol EQ-5D-3L, catastrophic loss of income and implementation outcomes (acceptability, adoption, appropriateness, costs, feasibility, fidelity, penetration, and sustainability) at one year. A nested pilot pre-post implementation study of an interventional bundle for all open fractures will be developed based on other implementation studies from low- and middle-income countries (LMICs). Regression analysis will be used to model and investigate associations between SMFA score and fracture severity, infection and the pre- and post-training course period. Outcome: This prospective cohort study will report patient reported outcomes from open tibia fractures in low-resource settings. Subsequent detailed evaluation of both the clinical and implementation components of the study will promote sustainability of improved open fractures management in the study sites and further scale-up of open fracture management guidelines. Ethics: Ethics approval has been obtained from the Liverpool School of Tropical Medicine and College of Medicine Research and Ethics committee.

Three-vessel view debridement of the open tibial fracture: a surgical technique

Adequate debridement of an open fracture is a key component of successful management. Despite having set debridement principles, there is no structured technique available in the literature to guide the surgeon in achieving this. We therefore present a technical note detailing the structured approach to the debridement of any open tibial fracture. Our unit has developed a novel stepwise technique termed locally as the "three-vessel view". Identifying all three primary vessels of the leg facilitates confirmation of inspection of all lower limb compartments thus minimising the risk of missed devitalised tissue or neglected areas of contamination and the potential for consequent disastrous outcomes as a result of inadequate exposure.

Short- and Long-Term Outcomes following Severe Traumatic Lower Extremity Reconstruction: The Value of an Orthoplastic Limb Salvage Center to Racially Underserved Communities

BACKGROUND

Previous studies have demonstrated that nonwhite race and disadvantaged socioeconomic status negatively impact outcomes following lower extremity reconstruction. The authors sought to characterize differences in outcomes between racial groups in patients necessitating traumatic lower extremity reconstruction at an orthoplastic limb salvage center.

METHODS

A retrospective review between 2002 and 2019 was conducted of patients who underwent free flap lower extremity reconstruction at an orthoplastic limb salvage center. Patient demographics were identified, and permanent addresses were used to collect census data. Short-term complications and long-term functional status were recorded.

RESULTS

One hundred seventy-three patients underwent lower extremity reconstruction and met inclusion criteria. Among all three groups, African American patients were more likely to be single (80 percent African American versus 49 percent Caucasian and 29.4 percent other; p < 0.05) and had significantly lower rates of private insurance compared with Caucasian patients (25 percent versus 56.7 percent; p < 0.05). African American patients demonstrated no significant differences in total flap failure (4.9 percent versus 8 percent and 5.6 percent; p = 0.794), reoperations (10 percent versus 5.8 percent and 16.7 percent; p = 0.259), and number of readmissions (2.4 versus 2.0 and 2.1; p = 0.624). Chronic pain management (53.3 percent versus 44.2 percent and 50 percent; p = 0.82), full weight-bearing status (84.2 percent versus 92.7 percent and 100 percent; p = 0.507), and ambulation status (92.7 percent versus 100 percent and 100 percent; p = 0.352) were similar among groups.

CONCLUSIONS

Outcomes are equivalent between racial groups presenting to an orthoplastic limb salvage center for lower extremity reconstruction. The postoperative rehabilitation strategies, follow-up, and overall support that an orthoplastic limb salvage center ensures may lessen the impact of socioeconomic disparities in traumatic lower extremity reconstruction.

Impact of the COVID-19 pandemic on the management of open fractures in a major trauma centre

INTRODUCTION

The Coronavrius-19 (COVID-19) pandemic has presented the biggest challenge that the National Health Service (NHS) has ever seen. As one of the worst affected regions, Orthopaedic service provision and delivery in London, changed dramatically. Our hypothesis is that these restrictions adversely impacted the care of open fractures in our major trauma unit in London.

METHODS

This is a prospective case control study comparing the management of patients presenting pre-COVID, to those presenting during the height of the COVID pandemic in London. The pre-COVID, control cohort presented between the 1st October and the November 30, 2019. The COVID cohort presented between the April 1, 2020 and the May 31, 2020. Data was collected that related to the 11 clinical domains of the British Orthopaedic Association Standards of Trauma (BOAST) 4 guidance, as well as early complications.

RESULTS

Of the 11 domains, 100 % compliance was achieved in 6 components, across both groups where applicable. During pre-COVID times, the timing to initial debridement was within 12 h for High energy trauma in 16/28 (57.1 %), dropping to 7/22 (31.8 %) during COVID, (p = 0.004). Definitive soft tissue closure within 72 h If not achievable at initial debridement dropped from 9/10 (90.0%) to 4/6 (66.7 %), (p = 0.006). There was no significant difference in early complication rates.

CONCLUSION

Coronavirus has changed the landscape of healthcare worldwide and impacted open fracture care by increasing time to theatre. This had no effect on early complication rate but longer term effects remain to be seen.

Strategies and outcomes in severe open tibial shaft fractures at a major trauma center: A large retrospective case-series

BACKGROUND

Severe open tibia fractures are challenging to treat with a lack of published clear management strategies. Our aim was to provide an overview of the largest single-center experience in the literature, with minimum 1-year follow-up, of adult type 3 open tibial shaft fractures at Cambridge University Hospitals (a United Kingdom major trauma center). We sought to define patient characteristics and our main outcome measures were infection, union and re-fracture.

AIM

To retrospectively define patient and injury characteristics, present our surgical methods and analyze our outcomes–namely infection, union and re-fracture rates.

METHODS

Consecutive series of 74 patients with 75 open tibial fractures treated between 2014 and 2020 (26 classified as Gustilo-Anderson 3A, 47 were 3B and two were 3C). Nine patients underwent intramedullary nailing (IMN), 61 underwent Taylor spatial frame (TSF) fixation and 5 were treated with Masquelet technique (IMN and subsequent bone grafting).

RESULTS

Mean follow-up was 16 mo (IMN) and 25 mo (TSF). We had an infection rate of 6.7% (5), non-union rate of 4% (3) and re-fracture rate of 2.7% (2). Average time to union was 22 wk for IMN and 38.6 wk for TSF. Thirty-three cases had a bone defect with a mean of 5.4 cm (2-11). Patient age, sex, diabetes, smoking status or injury severity did not have a significant effect on union time with either fixation method. Our limb salvage rate was 98.7%.

CONCLUSION

Grade 1 to 3A injuries can effectively be treated with reamed or unreamed IMN. Grade 3B/C injuries are best treated by circular external fixators as they provide good, reproducible outcomes and allow large bone defects to be addressed via distraction osteogenesis.

Orthoplastic Management of Open Midfoot Injuries: Is Functional Limb Salvage Possible?

High energy open midfoot injuries are uncommon but devastating injuries. A combination of complex fracture dislocations and soft tissue injury patterns render reconstruction challenging. The aim of this study was to assess the surgical and patient reported outcomes following orthoplastic management of open midfoot injuries in a Major Trauma Center. A retrospective review of all open midfoot fractures admitted to our unit between January 2015 and December 2016 was undertaken. Demographics, operative details, complications, additional surgeries, and patient reported outcomes in the form of EQ-5D and Enneking scores were collected. Fifteen patients were identified (13 male, mean age 39.2 years). One patient underwent amputation at initial debridement and 8 required additional debridement. Of these 8 patients, 3 had an amputation during their index admission. In the limb salvage group (11 patients), definitive soft tissue cover involved free flaps in 6 patients, split skin graft in 3 patients, and delayed primary closure in 2 patients. Definitive orthopedic treatment was internal fixation in 8 and external fixation in 3 patients. Two patients required a Masquelet procedure for bone loss. One patient had a toe amputation and 1 had a below knee amputation for deep infection. The median EQ-5D score was 66 (interquartile range 43), and the median Enneking score was 20.5 (interquartile range 9). Limb salvage following open midfoot fractures is technically possible in most cases, however this often involves multiple procedures and the outcomes are variable and difficult to predict. Patients should be carefully counseled, and amputation considered in all such cases.

Treatment of open tibia fractures in Sub-Saharan African countries : a systematic review

Open tibia fracture (OTF) treatment is well documented in developed countries. Yet, this fracture pattern remains challenging because it is associated with an increased risk of infection and delayed union, particularly in case of Gustilo III B and C open fractures. Since access to healthcare is limited in Sub- Saharan African countries, this paper explores the results of OTF management in this setting. A systematic review of the literature was conducted using current databases such as MEDLINE, Cochrane, EMBASE, PubMed, ScienceDirect, Scopus, and Google Scholar in order to identify prospective studies with cohorts of patients treated for OTF. Studies were included based on predefined inclusion and exclusion criteria. The quality of studies was analyzed by the Coleman Methodology Score (CMS). Eight papers met the inclusion criteria and had an average CMS of 70 (range 54-73). The most common treatment was non-operative management of the fracture with cast immobilization (67%). Gustilo Type II and III fractures were associated with a higher risk of complications. The infection rate was 30%. Malunion, chronic osteomyelitis and nonunion were observed in 14.5%, 12.3%, and 7% of the cases, respectively. More complications were observed with non-operative treatment (cast immobilization) than with surgical fixation. Although the surgical environment does not allow for internal fixation, poor results of non-operative management of open fractures should lead to the introduction of trainings on the proper use of external fixators. It is also advisable to support the development of locally produced external devices that utilize local source materials, which would make external fixation available at a reasonable cost.

The economic burden of open tibia fractures: A systematic review

BACKGROUND

Open tibia fractures are a common injury following road traffic collisions and place a large economic burden on patients and healthcare systems. Summarising their economic burden is key to inform policy and help prioritise treatment.

METHODS

All studies were identified from a systematic search of Medline, Embase and the Cochrane Central Register of Controlled Trials. We included any human with a diagnosed open tibia fracture, following any intervention. The primary outcome was any costs reported or patient return to work status. Secondary outcomes included average length of stay, wage loss, absenteeism and complications such as infection, amputation and nonunion. Data was extracted and we performed a descriptive narrative summary.

RESULTS

We reviewed 1,204 studies from our searches. A total of 34 studies were included from 14 different countries. The average age was 37.7 years old and 76% of the patients were male. 6.5% were Gustilo I, 12% Gustilo II and 82% Gustilo III. Initial direct hospitalisation costs were reported to be between £356 to £126,479 with an average length of stay of 56 days (3.1-244). 89% of participants were working pre-injury, 60% fully returned to work, 17% returned to work part time or changed profession and 22% did not return to work at one-year. The most common complications reported were 22% infection, 11% nonunion and 16% amputation. Mean follow-up duration for the studies was 25 months.

CONCLUSION

The economic burden of open tibia fractures varies greatly, but it is costly for both hospitals and patients. The current evidence is predominantly from high-income countries (HICs), especially the USA. Further research is required to investigate the costs of open tibia fractures using validated costing tools, especially in low-income countries (LICs), to help inform and direct policy.

Radical treatment of severe open fractures of extremities by orthoplastic surgery: a 10-year retrospective study

OBJECTIVE

This study aimed to retrospectively analyze clinical data of a series of patients with severe open fractures of extremities (Gustilo IIIb or IIIc), who achieved a satisfactory outcome through radical orthoplastic surgery, so as to provide a reference for determining the treatment of severe open fractures of extremities.

METHODS

The clinical data of 41 consecutive patients with severe open fracture (Gustilo IIIb or IIIc) of the limb, who underwent successful surgical debridement, fixation, and soft tissue reconstruction in one stage between January 2008 and January 2019, were retrospectively reviewed. Postoperative indicators, including infection rate and union time, were acquired by a regular follow-up and analyzed.

RESULTS

The mean (±SD) age of the patients was 38 ± 16 years. A total of 90 open fractures and severe soft tissue damages were analyzed. The soft tissue cover was achieved within 72 h. The overall rate of infection was 14.6% (6/41). Sex and the Mangled Extremity Severity Score were associated with infection. The median union time of 40 patients (one amputation) was 32 weeks.

CONCLUSION

The overall rate of infection exhibited a lower tendency in this study compared with previous studies on high-grade open fractures following a two-stage orthopedic approach. The consequence of infection rate and union time was similar to that in previous studies. These results indicated that the single-stage radical orthoplastic treatment was an effective and reliable option for reconstructing severe open fractures.

Utilizing the various forms of the gastrocnemius muscle in fix & flap protocol: a reliable remedy for open proximal tibial fractures with accompanying soft tissue defect

BACKGROUND

Open proximal tibial fractures accompanied by soft tissue loss are substantially challenging to accomplish both bony consolidation and wound healing. The authors retrospectively delineated the utility of the various forms of the gastrocnemius muscle in fix & flap regimen for management of such complicated injuries.

METHODS

Thirty-one patients with open fracture accompanied by soft tissue loss of proximal tibia were managed by the protocol of fix & gastrocnemius flap. The collected data included implant for fixation, form of the gastrocnemius flap, postoperative complications, union time, and clinical assessment.

RESULTS

According to fixation devices, lateral anatomical locking compression plates were selected in 28 cases, dual plates in 1, and interlocking nails in 2. According to the forms of the gastrocnemius flap, medial gastrocnemius flap was utilized in 22 cases, medial hemigastrocnemius flap in 2, medial myocutaneous gastrocnemius flap in 2, lateral gastrocnemius flap in 3, and combined medial and lateral gastrocnemius flaps in 2. All flaps completely survived without any flap-related complications. Fracture consolidation was established in all patients with an average period of 19.9 weeks (range 16-26). Surgical site infection occurred in 3 cases, and delayed union in 1. By functional score of Puno, 3 cases were determined to be excellent, 27 to be good, and 1 to be fair.

CONCLUSION

Concurrent use of internal fixation and gastrocnemius flap reconstruction is a reliable and efficient protocol in managing open fractures with accompanying soft tissue defect of proximal tibia.

Delay in Initial Debridement for Open Tibial Fractures and Its Possible Impact on Patient Outcomes: A Single-Center Prospective Cohort Study

The current consensus regarding the management of open fracture indicates that the initial debridement should be performed within the first 6 hours after injury. Unfortunately, in Pakistan, the emergency medical services are not well-established and patient arrival at the hospital is delayed the majority of the time. In this study, we present our experience with delayed surgical management of open tibial fractures.

Standards of open lower limb fracture care in the United Kingdom

Open fractures of the lower limb remain a potentially devastating group of injuries that are challenging to manage. The primary aims of treatment are to optimise limb function and avoid serious complications such as infection and non-union, which are costly for both the patient and healthcare system. The management of these fractures has evolved significantly, and this is evident following the creation of national open fracture guidelines and a formal trauma system. These have served to standardise care for these injuries in the United Kingdom. The aim of this review is to update our colleagues on the current standard of lower limb open fracture care in the United Kingdom, and the impact this has had on patient outcomes.

The Malawi Orthopaedic Association/AO Alliance guidelines and standards for open fracture management in Malawi: a national consensus statement

Background

Open fractures are common injuries in Malawi that pose a large burden on the healthcare system and result in long-term disability.

Aim

Establishing a multiprofessional agreement on the management of open fractures in Malawi from a consensus meeting.

Methods

AO Alliance convened a consensus meeting to build an agreement on the management of open fractures in Malawi. Eighteen members from different professions and various regions of Malawi participated in a 1-day consensus meeting on 7 September 2019. Prior to the meeting the British Orthopaedic Audit Standards for Trauma (BOAST) for open fractures, as well as relevant systematic reviews and seminal literature were circulated. Panel members gave presentations on open fracture management, followed by an open discussion meeting. At the 1-day consensus meeting panel members developed statements for each standard and guideline. Panel members then voted to accept or reject the statements.

Results

Substantial agreement (no rejections) was reached for all 17 guidelines and the associated terminology was agreed on. These guidelines were then presented to the members of the Malawi Orthopaedic Association (MOA) at their annual general meeting on 28 September 2019 and all participants agreed to adopt them.

Conclusions

These MOA/AO Alliance guidelines aim to set a standard for open fracture management that can be regularly measured and audited in Malawi to improve care for these patients.

A Reevaluation of the Risk of Infection Based on Time to Debridement in Open Fractures: Results of the GOLIATH Meta-Analysis of Observational Studies and Limited Trial Data

BACKGROUND

Open fractures are one of the leading causes of disability worldwide. The threshold time to debridement that reduces the infection rate is unclear.

METHODS

We searched all available databases to identify observational studies and randomized trials related to open fracture care. We then conducted an extensive meta-analysis of the observational studies, using raw and adjusted estimates, to determine if there was an association between the timing of initial debridement and infection.

RESULTS

We identified 84 studies (18,239 patients) for the primary analysis. In unadjusted analyses comparing various "late" time thresholds for debridement versus "early" thresholds, there was an association between timing of debridement and surgical site infection (odds ratio [OR] = 1.29, 95% confidence interval [CI] = 1.11 to 1.49, p < 0.001, I2 = 30%, 84 studies, n = 18,239). For debridement performed between 12 and 24 hours versus earlier than 12 hours, the OR was higher in tibial fractures (OR = 1.37, 95% CI = 1.00 to 1.87, p = 0.05, I2 = 19%, 12 studies, n = 2,065), and even more so in Gustilo type-IIIB tibial fractures (OR = 1.46, 95% CI = 1.13 to 1.89, p = 0.004, I2 = 23%, 12 studies, n = 1,255). An analysis of Gustilo type-III fractures showed a progressive increase in the risk of infection with time. Critical time thresholds included 12 hours (OR = 1.51, 95% CI = 1.28 to 1.78, p < 0.001, I2 = 0%, 16 studies, n = 3,502) and 24 hours (OR = 2.17, 95% CI = 1.73 to 2.72, p < 0.001, I2 = 0%, 29 studies, n = 5,214).

CONCLUSIONS

High-grade open fractures demonstrated an increased risk of infection with progressive delay to debridement.

A Novel Treatment of a 65-Year-Old Woman with a Neglected Type IIIB Open Fracture of the Tibia with Inadequate Soft Tissue Coverage and Periosteal Stripping Requiring an Ilizarov Approach to Bone and Soft Tissue Lengthening and Reconstruction: A Case Report and Review of the Literature

BACKGROUND Type IIIB open bone fractures include loss of soft tissue with periosteal stripping and need rapid surgical repair. The Ilizarov method of bone lengthening and reconstruction offers limb salvage as an alternative to amputation. CASE REPORT We report a case of a neglected type IIIB open fracture of the tibia with inadequate soft tissue coverage and periosteal stripping requiring an Ilizarov approach for limb salvage in a 65-year-old woman. Surgical debridement resulted in a large bone deficit of 13 cm. Acute shortening facilitated wound closure, and the remaining skin defect was treated with skin grafting. Bone transport and limb lengthening techniques, in addition to skin expansion and support, were used to restore the length of the tibia. The regenerated bone had to be fused with the talus since the tibial plafond was excised during debridement. The external fixator was removed after 643 days of treatment. An external fixation index of 49.6 d/cm was estimated. Excellent bone and good functional results were obtained according to the criteria of the Association for the Study and Application of the Method of Ilizarov. Skin invagination, bone translocation, and pin tract infection were the major postoperative issues. CONCLUSIONS This case showed that a multidisciplinary approach may be required for the successful management of neglected open fractures of the tibia and that the Ilizarov approach to both bone and soft tissue lengthening and reconstruction should be considered to ensure limb salvage and improve the final cosmetic appearance.

Socioeconomic position is associated with surgical treatment of open fractures of the lower limb: results from a Swedish population-based study

Background and purpose - High-energy trauma to the lower limbs can result in open fractures, treated by reconstructive surgery or amputation. We examined whether socioeconomic position is associated with choice of primary treatment.Patients and methods - We performed a nationwide population-based study using the Swedish National Patient Register to identify all adult patients who between 1998 and 2013 underwent reconstruction or amputation after an open fracture below the knee. Information on socioeconomic position was collected from Statistics Sweden.Results - Of 275 individuals undergoing surgery after an open fracture below the knee during the study period, the 1st surgery was reconstructive in 58% of the patients and amputation in 42%. The chance of having an initial reconstruction was lower for women than for men (OR 0.5, 95% CI 0.3-0.9), lower with age (OR 0.97, CI 0.96-0.99), and lower for individuals without employment compared with individuals in employment (OR 0.3, CI 0.2-0.5). Primary treatment was in women associated with family composition, whereas in men it was associated with level of education.Interpretation - Choice of primary treatment after open fracture in the lower limb is affected by socioeconomic position including sex, age, employment, family composition, level of education, and income.

Identifying Factors Most Important to Lower Extremity Trauma Patients: Key Concepts from the Development of a Patient-Reported Outcome Instrument for Lower Extremity Trauma, The LIMB-Q

BACKGROUND

Severe lower extremity injuries are challenging to treat. The aspects of limb salvage and amputation most important to patients are not well-defined. This study's aim is to develop a conceptual framework for a patient-reported outcome instrument for lower extremity trauma patients, by defining issues and concepts most important to this patient population.

METHODS

This is an interpretative description of transcripts collected from semistructured qualitative interviews at a single institution. High-energy lower extremity trauma patients were recruited by means of purposeful sampling to maximize variability. Thirty-three participant interviews were needed to reach content saturation. These participants were aged 19 to 79 years; 21 were men (63.6 percent); participation was after reconstruction [n= 15 (45.5 percent)], after amputation [n = 11 (33.3 percent)], or after amputation after failed reconstruction [n = 7 (21.2 percent)]. Interviews were recorded, transcribed, and coded line-by-line. Concepts were labeled with major and minor themes and refined through a process of constant comparison. Analysis led to the development of a conceptual framework and item pool to inform the development of a patient-reported outcome measure.

RESULTS

In total, 2430 unique codes were identified and used to generate the conceptual framework covering 10 major themes: appearance, environment, finances, physical, process of care, prosthesis, psychological, sexual, social, and treatment.

CONCLUSIONS

This study establishes a comprehensive set of concepts, identifying what is most important to severe lower extremity trauma patients. These findings can be used to inform and focus research and clinical care, and provides the framework to develop a lower extremity trauma-specific patient-reported outcome instrument: the LIMB-Q.

The interest of "ortho-plastic" collaboration in management of complex limb injury

Constantly evolving knowledge on fracture management, soft tissue coverage, microsurgery and vasculo-nervous repair now permits salvage of limbs that previously would have had to be amputated. Management of complex limb injuries of which the severity inevitably entails functional and esthetic sequelae calls for mastery of the full spectrum of bone and soft tissue reconstruction. Such mastery is rarely attainable by a single surgical specialty; individually and isolatedly, an orthopedic or plastic surgeon cannot ensure optimal management of the above-mentioned patients. While the orthopedist performs a key function in provisional or definitive fixation, the plastic surgeon's expertise is essential to restoration of the cutaneous envelope. Collaboration between the two specialties from the outset and throughout treatment characterizes the modern-day concept of "ortho-plastic" surgery. Through unification of the theoretical competence and practical skills of orthopedists and plastic surgeons, it provides a patient with the best possible functional and esthetic results in a wide range of clinical situations. In this article, we present a review of the literature illustrating the interest of "ortho-plastic" collaboration in management of complex limb injury; concrete examples will be given through evocation of clinical cases encountered by the team that was put together in August 2015 at the university hospital (CHU) of Lille.
