Does timing to operative debridement affect infectious complications in open long-bone fractures? A systematic review

Infection After Open Fracture in Children

Infection after open fracture is much less common in children than in adults, but it still requires special attention to help prevent, diagnose, and treat when it does occur. In this review, we examine strategies for preventing infection once open fracture is recognized, diagnostic criteria for infection, and treatment approaches for infection after open fracture in children. We highlight differences in pediatric care from adult care and discuss practice variabilities based on the lack of available data to guide certain treatment patterns.

Open fractures of the lower leg: Outcome and risk-factor analysis for fracture-related infection and nonunion in a single center analysis of 187 fractures

BACKGROUND

Open fractures of the lower extremity have a higher risk of fracture-related infections (FRI) or nonunion. The purpose of this study was to identify risk factors for complications and evaluate outcomes.

METHODS

In this retrospective, single center study, we identified and included 187 patients with extraarticular and intraarticular fractures of the tibia or fibula between 2010 and 2018. Patient characteristics, treatment protocols, and complications were assessed, with a focus on soft tissue management and timing of wound closure versus fracture fixation. To analyze risk factors for FRI and nonunion, a univariate logistic regression model was used.

RESULTS

The open fractures included were 52 Gustilo-Anderson type-I (28 %), 99 type-II (53 %), and 36 type-III (19 %) fractures. The mean time from admission to first surgical intervention was 3.47 h (SD 1.4), with 122 (60 %) patients treated within 3 h and 182 (97 %) patients, within 6 h. During primary surgery, definitive fracture fixation was carried out in 112 (60 %) patients and wound closure in 122 (65 %) patients. FRI was reported in 27 (14 %) patients with the highest prevalence in type-III fractures (31 %). Secondary wound closure was associated with a significantly higher risk for FRI than primary wound closure (odds ratio [OR] = 3.3; p = 0.004). Nonunion was reported in 37 (20 %) patients. Significant risk factors for nonunion were FRI (OR=11.9, p < 0.001) and definitive fracture fixation before wound closure compared to fracture fixation and wound closure at the same time (OR = 8.2, p < 0.001). Gustilo-Anderson type-IIIb and -IIIc fractures had a significant lower FRI-free survival compared to other fractures. No patient underwent amputation during the follow-up.

CONCLUSION

Open fractures of the tibia and fibula are associated with a high risk of FRI and nonunion. FRI is the strongest predictor of nonunion in open fractures of the lower extremity. Primary wound closure and simultaneous definitive fracture fixation are protective even in higher Gustilo-Anderson fracture types and prevent complications. Early antibiotic therapy and surgical treatment are crucial, as evidenced by all cases receiving treatment within 6 h post trauma.

Timing in orthopaedic surgery - Rethinking traditional myths with a critical perspective

PURPOSE

Standard operating procedures aim to achieve a standardized and assumedly high-quality therapy. However, in orthopaedic surgery, the aspect of temporal urgency is often based on surgical tradition and experience. At a time of evidence-based medicine, it is necessary to question these temporal guidelines. The following review will therefore address the most important temporal guidelines in orthopaedic surgery and discuss their practical relevance and potential need for optimization.

METHODS

The systematic review features a literature review by database search in "PubMed" (https://pubmed.ncbi.nlm.nih.gov) for time to surgery in terms of (1) "proximal femoral fractures", (2) "femoral neck fractures", (3) "proximal humeral fractures", (4) "ligament and tendon injuries", (5) "spinal cord injuries", (6) "open fractures" and (7) "fracture-related infections". For every diagnosis, hypotheses on timing were set up and checked for evidence.

RESULTS

There is solid clinical evidence supporting the initiation of treatment within 24 h for specific conditions like the surgical treatment of proximal femur fractures and prompt decompression of spinal cord injuries. However, for other scenarios such as the 6-hour rule for open fractures, joint-preserving femoral neck fractures, timing of ligament injuries, humeral head fractures and fracture-related infections there is currently no reliable evidence to guide prompt surgical treatment.

CONCLUSION

Based on the current data, resource-adapted surgical planning seems reasonable. Further research in these areas is necessary to determine the best timing of treatment and address existing doubts.

Severe soft tissue injuries in multiple trauma patients-a challenge we can meet? A matched-pair analysis from the TraumaRegister DGU®

Introduction

Despite tremendous clinical efforts over the past few decades, the treatment of severely injured patients remains still challenging. Concomitant soft tissue injuries represent a particular challenge, as they can lead to complications at any time of trauma care, hold a high risk of infection and often require multiple surgical interventions and interdisciplinary collaboration.

Methods

This retrospective, multicentric study used the TraumaRegister DGU® to examine the effect of open fractures and severe soft tissue injuries on outcome of multiple trauma patients. Primary admitted multiple trauma patients at the age of 16 to 70 years, treated from 2010 to 2021, were included. A Matched pair analysis was performed for better comparability of trauma patients with and without open fractures and/or severe soft tissue injuries.

Results

After applying the matching criteria, 5,795 pairs were created and analyzed. The group with sustained soft tissue injuries/open fractures was found to have a higher ISS ([mean ± SD] 22.1 ± 10.4 vs. 20.6 ± 10.2, p < 0.001). Endotracheal tube insertion (27.7% vs. 30.4%, p = 0.003), catecholamine administration (6.0% vs. 8.4%, p < 0.001) and cardio-pulmonary resuscitation (1.6% vs. 2.1%, p = 0.027) were more frequent in the group with sustained soft tissue injury. Both groups were equally frequent admitted to the intensive care unit (ICU) and length of stay (LOS) at the ICU (median (quartiles) 3 (1-9) versus 3 (1-9)) did not differ significantly. However, total LOS at the hospital was longer for the group with sustained soft tissue injury (median (quartiles) 18 (11-29) versus 17 (10-27)). Sepsis occurred more often in patients with soft tissue injury (4.3% vs. 5.2%, p = 0.034). There was no significant difference in prevalence of multi organ failure, 24 h-mortality (2.1% vs. 2.5%, p = 0.151) and overall-mortality (3.6% vs. 3.9%, p = 0.329) between both groups.

Conclusion

Due to database analysis and revision of guidelines, the treatment of severely injured patients has steadily improved in recent years. Patients with severe soft tissue injuries/open fractures required more medical interventions and length of stay at the hospital was longer. In this study, we were able to show that although concomitant severe soft tissue injuries required more ICU interventions and led to a longer length of stay, 24-h and all-cause mortality were not significantly increased.

Novel antibiotics against Staphylococcus aureus without detectable resistance by targeting proton motive force and FtsH

The increased prevalence of methicillin-resistant Staphylococcus aureus (MRSA) and its biofilms poses a great threat to human health. Especially, S. aureus-related osteomyelitis was hardly cured even by conventional antibiotics combined with surgical treatment. The development of novel structural antibiotics is urgently needed. By high-throughput screening and rational design, we identified a small molecule C218-0546 and its optimized analog STK848198 with great antimicrobial potential against MRSA avoiding resistance occurrence. And significant synergistical antimicrobial effects were found between the molecules and conventional antibiotics. Mechanisms studies by transcriptomics, fluorescent probes, molecule dynamics, and plasma surface resonance indicated that the proton motive force as well as FtsH are the main potential targets of these molecules. The compounds exhibited excellent in vivo pharmacokinetics, toxicity profiles, and antimicrobial activities in the abscess model as well as the peritonitis-sepsis model. In addition, STK848198 was found to be effective against MRSA biofilms by interacting with the quorum sensing system. STK848198 also showed in vivo efficacy in the periprosthetic joint infection model. In all, our study identified a class of antimicrobials with novel scaffolds that could be potential alternatives for the treatment of MRSA and its biofilm-related infections.

Multidisciplinary standardized protocol decreases time to antibiotic administration for open fractures

PURPOSE

Wound complications after open fracture are common, including superficial and deep infections. Many factors may contribute to outcomes after open fracture, including comorbidities, injury location and characteristics, timing and quality of surgical debridement, and soft tissue coverage. Early prophylactic antibiotic administration is one of the few modifiable factors demonstrated to reduce infection rates.

METHODS

Retrospective comparative study at a single Level 1 Trauma Center evaluated patients age > 18 who presented directly to and were admitted with open long-bone fracture. Primary outcome measure was time from arrival to antibiotic administration pre- and post-implementation of a standardized open fracture protocol. Secondary analysis evaluated percentage of patients receiving antibiotics within one hour for open long-bone fracture, injury characteristics and patient demographics influence on time to antibiotics.

RESULTS

Median time to antibiotic administration improved post-protocol (69 min vs. 39 min, p < 0.001). Patients receiving antibiotics within one hour improved after protocol implementation (42.9% vs. 79.0%, p < 0.001). Antibiotic administration was more often delayed for patients with penetrating injuries compared to blunt injuries (80 min vs. 54 min, p = 0.003). Patients with penetrating injuries were less likely to receive antibiotics within one hour (46% vs 56%, p < 0.001).

CONCLUSIONS

The implementation of a standardized protocol reduced the time to antibiotic administration and increased the percentage of patients with open fractures receiving antibiotics within one hour. Penetrating injuries were often not appreciated as open fractures during the initial evaluation, which led to a delay in antibiotic administration.

Initial treatment of severe soft-tissue injuries in closed and open fractures to prevent fracture-related infection

The management of soft tissue damage during fracture treatment requires surgical proficiency and meticulous care adhering to established treatment protocols. This approach is paramount for minimizing the risk of potentially limb- or even life-threatening complications such as fracture-related infection (FRI) in all age groups. There is a general consensus on essential measures such as wound assessment, surgical debridement and early use of antibiotics. Treatment should always be based on the correct classification of the fracture and the corresponding soft tissue injury, but needs to be adapted to the individual patient considering general health status, secondary diagnoses and currently available treatment options.

Management of Acute Wounds-Expert Panel Consensus Statement

Significance: The Wound Healing Foundation recognized the need for consensus-based unbiased recommendations for the treatment of wounds. As a first step, a consensus on the treatment of chronic wounds was developed and published in 2022. The current publication on acute wounds represents the second step in this process. Acute wounds may result from any number of conditions, including burns, military and combat operations, and trauma to specific areas of the body. The management of acute wounds requires timely and evidence-driven intervention to achieve optimal clinical outcomes. This consensus statement provides the clinician with the necessary foundational approaches to the causes, diagnosis, and therapeutic management of acute wounds. Presented in a structured format, this is a useful guide for clinicians and learners in all patient care settings. Recent Advances: Recent advances in the management of acute wounds have centered on stabilization and treatment in the military and combat environment. Specifically, advancements in hemostasis, resuscitation, and the mitigation of infection risk through timely initiation of antibiotics and avoidance of high-pressure irrigation in contaminated soft tissue injury. Critical Issues: Critical issues include infection control, pain management, and the unique considerations for the management of acute wounds in pediatric patients. Future Directions: Future directions include new approaches to preventing the progression and conversion of burns through the use of specific gel formulations. Additionally, the use of three-dimensional bioprinting and photo-modulation for reconstruction is a promising area for continued discovery.

Risk factors for infection in severe open tibial shaft fractures

OBJECTIVE

To evaluate risk factors for infection in severe open tibial shaft fractures.

METHODS

A secondary analysis of a multicenter prospective study investigated internal versus external fixation of severe open tibia fractures at 20 US Level I trauma centers. Adult patients, aged <65 years, with a Gustilo-Anderson Type IIIB or severe IIIA metaphyseal or diaphyseal tibia fracture were included. All fractures underwent definitive fixation with either a modern ring external fixator, intramedullary device, and/or plate. Fourteen variables previously identified as risk factors for infection were included in the analysis. Deep surgical site infection was defined as an infection treated with surgical debridement within 1 year of index surgery.

RESULTS

The study cohort included 430 patients. Deep surgical site infection requiring reoperation occurred in 108 (25 %) patients. The final model identified four risk factors for infection: age >40 years (OR, 2.00; 95 % CI, 1.3-3.1), Gustilo-Anderson Type IIIB (OR, 1.80; 95 % CI, 1.1-3.0), embedded wound contamination (OR, 1.69; 95 % CI, 1.1-2.7), and wound length (OR, 1.02/cm; 95 % CI, 1.0-1.05). The model performed poorly at distinguishing infected from uninfected patients (Area Under the Curve=0.57; 95 % CI, 0.51-0.63).

CONCLUSIONS

Surgeons can now counsel patients with these risk factors that they are at a markedly higher risk of infection. The identification of these risk factors may direct future research aimed at mitigating the risk of deep surgical site infection in this patient population.

Prehospital Antibiotic Administration for Suspected Open Fractures: Joint COT/OTA/ACEP/NAEMSP/NAEMT Position Statement

One of the primary concerns associated with open fractures is the development of a fracture-related infection (FRI). To minimize the risk of developing an FRI and subsequent morbidity, prophylactic antibiotics should be administered to patients with open fractures as soon as possible. While the antibiotic recommendations for severe open fractures are somewhat debatable, the use of a cephalosporin remains a mainstay of prophylactic treatment. Though administration of prehospital antibiotics does represent an expansion of EMS responsibilities, there have been several other treatment expansions in the prehospital setting, such as the administration of tranexamic acid and the application of pelvic binders. The administration of antibiotics, specifically cefazolin, is inexpensive, technically simple, and does not require special storage. The following recommendations are supported by and represent consensus of the COT, OTA, ACEP, NAEMSP and NAEMT with regards to prehospital antibiotic prophylaxis for suspected fractures: In a responsive patient with no history of penicillin or cephalosporin allergy, the administration by EMS of a 1st generation cephalosporin should be performed after the management of life threats. This intervention should not delay transport.In an obtunded patient, the administration by EMS of a 1st generation cephalosporin should be performed after the management of life-threats. This intervention should not delay transport.In a responsive patient with a documented penicillin allergy, the administration by EMS of a 1st generation cephalosporin should be performed with close monitoring after the management of life-threats. This intervention should not delay transport.

Comparison of Early Versus Late Debridement Outcomes in the Management of Open Distal Radius Fractures

PURPOSE

The optimal timing for surgical treatment of open distal radius fractures remains an area of debate. The purpose of this study was to examine the outcomes of open distal radius fractures treated surgically before or after 24 hours.

METHODS

A multicenter retrospective review was performed on all open distal radius fractures treated over 11 years. Patient demographics, injury mechanism, and initial treatment were recorded. Fracture severity was graded by the Gustilo-Anderson classification. Comparisons were made between those treated surgically within and after 24 hours. Outcomes examined included infection, revision surgery, osteomyelitis, and nonunion.

RESULTS

A total of 230 cases met the inclusion criteria. The cohorts of early and delayed surgical intervention were similar with regard to preoperative demographics. The most common mechanism of injury was motor vehicle accident. Approximately 40% of cases were graded as type I, 40% as type II, and 20% as type III. Mean time to debridement in the group treated after 24 hours was 5 days. A mean postoperative follow-up of greater than 6 months was obtained in both cohorts. Similar outcomes were found between cohorts with respect to postoperative infection, revision surgery, osteomyelitis, and nonunion.

CONCLUSIONS

Similar outcomes with regards to infection, revision, osteomyelitis, and nonunion were found between open distal radius fractures treated emergently versus those managed in a delayed fashion. Patient- and injury-specific factors are important in dictating care.

Contemporary management of open extremity fractures: What you need to know

ABSTRACT

Open extremity fractures are high-risk injuries prone to significant complications, including soft tissue loss, bone defects, infection, infected nonunion, and the necessity for limb amputation. Large-scale multicenter prospective studies from the Lower Extremity Assessment Project and the Major Extremity Trauma Research Consortium have provided novel scientific insights pertinent to the timeliness and appropriateness of specific treatment modalities aimed at improving outcomes of patients with open extremity injuries. These include the imperative for early administration of intravenous antibiotics within 3 hours of injury, preferably within 1 hour of hospital admission. Unlike the proven value of early antibiotics, the time to initial surgical debridement does not appear to affect infection rates and patient outcomes. Recent evidence-based consensus guidelines from the American Academy of Orthopedic Surgeons provide scientific guidance for preventing surgical site infections in patients with open extremity fractures and support the decision making of limb salvage versus amputation in critical open extremity injuries. Patient survival represents the overarching priority in the management of any trauma patient with associated orthopedic injuries. Therefore, the timing and modality of managing open fractures must take into account the patient's physiology, response to resuscitation, and overall injury burden. The present review was designed to provide a state-of-the-art overview on the recommended diagnostic workup and management strategies for patients with open extremity fractures, based on the current scientific evidence.

Association of Timing With Postoperative Complications in the Management of Open Distal Radius Fractures

BACKGROUND

This study investigates whether open distal radius fractures (ODRFs) treated after 24 hours from time of injury have an increased risk of infection or overall complication profile compared with those treated within 24 hours.

METHODS

Retrospective review was performed of all patients treated for ODRF over a 6-year period at a single large academic institution. Postoperative complications included surgical site infections, need for revision irrigation and debridement, delayed soft tissue healing, loss of reduction, nonunion, and malunion.

RESULTS

One-hundred twenty patients were treated for ODRF. Mean (SD) age at time of injury was 59.92 (17.68) years. Twenty patients (16.7%) had postoperative complications. Regarding mechanism of injury, 78 (65.0%) had a low-energy and 42 (35.0%) had a high-energy injury. Age and fracture grade were not significant factors. Mean (SD) open wound size was 1.18 (1.57) cm. Mean (SD) time from injury presentation to the emergency department (ED) and first dose of intravenous antibiotics was 3.07 (4.05) hours and mean (SD) time from presentation to the ED and operative treatment was 11.90 (6.59) hours, which did not show a significant association with postoperative complications. Twenty-four patients (20.0%) were treated greater than 24 hours after presentation to the ED, which was not significantly distinct from those treated within 24 hours.

CONCLUSION

Patients with ODRFs treated after 24 hours were not associated with a greater risk of postoperative complications. Factors including age, energy and mechanism of injury, and fracture grade did not alter outcome in any statistically significant manner.

Lower Extremity Open Fractures Fix and Flap: Does Initial Management in Non-specialized Hospitals Really Compromise its Outcome?

Introduction Managing open lower extremity fractures is challenging, with potential complications such as amputation and infection. The aim of the study was to determine whether the time delay and initial treatment of the patients treated in a non-specialized hospital before being transferred to a dedicated level I trauma center led to a worse outcome. Methods Retrospective data from 44 patients (37 males and seven females) undergoing free tissue transfer for lower extremity open fractures from January 2017 to December 2022 were analyzed. Group A received primary care externally and was later transferred for definitive treatment (n=17, 38.6%), while group B received initial care at a level I trauma center (n=27, 61.4%). Surgical outcomes, complications, the duration of the hospital stay, and assessment times were compared. Various demographic variables, co-morbidities, prior interventions, and flap types were analyzed.  Results Average age (A: 55.1±16.7; B: 38.7±19.8 years; p=0.041), overall hospitalization (A: 55.7±22.8; B: 42.8±21.3 days; p=0.041), and time to soft tissue reconstruction differed significantly between groups (A: 30.7±12.2; B: 18.9±9.3 days; p=0.013). Overall, 31.8% had multiple injuries without statistical differences between groups A and B (29.4% vs. 33.3%; p>0.05). There were no statistical differences between the groups in terms of major and minor complications and bone healing characteristics. Limb salvage was successful overall in 93.2% (A: 94.1%; B: 92.6%; P>0.05). Major complications occurred in 9.1%; three patients underwent major amputation (A: n=2; B: n=1). Minor complications were observed in 43.2% of patients (partial flap necrosis, wound dehiscence and non-union; A: 41.2%; B: 44.4%; p>0.05). Overall, 65.9% of patients (A: 64.7%; B: 66.7%; p>0.05) experienced uneventful bone healing, while 18.2% of patients (A: 23.5%; B: 14.8%; p>0.05) experienced delayed healing. Flaps used were mostly musculocutaneous (71.7%). Various assessed demographic characteristics, including age and presence of polytrauma, showed no significant influence on complications (p>0.05). Conclusion  Although there is a significant difference in the time course of externally treated patients with open fractures, prolonged treatment is not associated with a higher complication rate or compromised bone healing outcome. Despite the findings, it is important to avoid delays and strive for interdisciplinary collaboration.

Risk Factors for Wound Failure After Primary Closure of Type IIIA Open Tibia Fractures

The objective of our investigation was to explore risk factors associated with primary closure of type IIIA tibial fractures resulting in subsequent flap coverage. A retrospective study identified 278 patients with acute type IIIA open tibial fractures who underwent primary closure at a single center during an 8-year period. Treatment factors, including the number of debridements before closure, duration of external fixation, and timing of wound closure, were reported. The primary outcome was complication requiring unplanned operation of the study injury resulting in flap coverage. Fifty-five (20%) patients underwent flap coverage following complication after attempted primary closure. Patients who required a flap experienced a 42% complication rate after delayed flap coverage. The limb salvage rate was 95% for the study population. Three significant complication predictors were identified: 3 or more debridements before closure (odds ratio [OR], 29.8; 95% CI, 5.9-150.1; P<.001), wound closure more than 2 days after injury (OR, 9.8; 95% CI, 1.6-60.2; P=.01), and external fixation more than 14 days (OR, 7.3; 95% CI, 1.6-34.6; P=.01). Patients who had 3 or more debridements before closure had a 70.7% chance of having a complication resulting in a flap (29 of 41) compared with only a 6.8% chance of complication for those who had 2 or fewer debridements (14 of 205; P<.001). Risk factors for complication after primary closure of type IIIA open tibial fractures include number of debridements, wound closure after 2 days, and external fixation use for more than 14 days. Wounds requiring 3 or more debridements failed 70.7% after closure, suggesting alternative approaches should be considered in more severe cases. [Orthopedics. 2024;47(2):108-112.].

The Effect of Topical Antibiotic Powder Application in the Emergency Department on Deep Fracture-Related Infection in Type III Open Lower Extremity Fractures

OBJECTIVE

Despite advances in management, open fractures are at an elevated risk for deep fracture-related infection (FRI). Time to systemic antibiotic (ABX) administration and intraoperative topical administration of ABX powder have been used to decrease FRI risk. The purpose of this study was to determine whether topical application of antibiotic powder to type III open lower extremity fractures immediately on presentation to the emergency department (ED) reduces the rate of FRI.

METHODS

DESIGN

Prospective cohort compared with retrospective historical control.

SETTING

Level I trauma center.

INTERVENTION

Application of 1 g of vancomycin and 1.2 g of tobramycin powder directly to open fracture wounds on presentation to the ED.

PATIENT SELECTION CRITERIA

Patients with type III open lower extremity fractures treated from July 1, 2019, to September 17, 2022, who received topical ABX powder in the ED were compared with patients from a 4-year historical cohort from July 1, 2015, to June 30, 2019, who were treated without topical ABX powder.

OUTCOME MEASURES AND COMPARISONS

Development of a FRI within 6 months of follow-up. Patient demographics, injury characteristics, and postoperative data were analyzed as risk factors for FRI.

RESULTS

Sixty-six patients received topical ABX powder in the ED and were compared with 129 patients who were treated without topical ABX powder. The rate of FRI in the trial group was 6/66 (9.09%) versus 22/129 (17.05%) in the control cohort ( P = 0.133). Multivariate analysis demonstrated higher body mass index as a risk factor for development of FRI ( P = 0.036).

CONCLUSION

No statistically significant difference in rates of FRI in open lower extremity fractures treated with immediate topical ABX administration in the ED versus standard-of-care treatment without topical ABX was found. These findings may have been limited by insufficient power. Further large-scale study is warranted to determine the significance of topical antibiotic powder application in the ED.

A novel primary antibiotic cement-coated locking plate as a temporary fixation for the treatment of open tibial fracture

Complex lower extremity trauma reconstruction remains a challenge. This study used an internal fixation composite structure of antibiotic cement plates as a temporary fixation to treat lower extremity Grade III open fractures; thus, reducing the treatment period and complications of external fixation. We aimed to assess the safety and efficacy of this technique in the initial surgery stage. Between January 2018 and March 2021, 20 patients with Gustilo grade IIIB/C open fractures received an antibiotic cement-coated locking plate as a temporary internal fixator during initial surgery. Thorough debridement and temporary internal fixation were performed with a 3.5-mm system antibiotic cement-coated locking plate. Ten patients required free bone fragment removal, followed by bone cement packing. The final stage involved internal fixation and wound repair with a free anterolateral thigh flap. Clinical and imaging results were retrospectively analysed. The repair time ranged 1-7 days. All flaps survived. Two patients experienced wound infection, and one developed severe bone infection 3 months after three-stage bone graft surgery. Autologous cancellous bone grafting was performed on 10 patients with bone defects 6 weeks after surgery. Bone union was universally achieved after 1 year. This method proved safe and effective, successfully repairing Grade III open fractures of the lower extremity 1-7 days post-treatment.

Immediate Soft Tissue Reconstruction in Lower Limb Traumas Using Propeller Perforator Flaps

BACKGROUND

Open bone fractures represent a demanding clinical condition that can be life- or limb-threatening. For small- to medium-size soft tissue defects of the lower extremity, propeller perforator flaps are a viable option for reconstruction. We report our experience in Gustilo IIIB open fractures treatment with immediate coverage through propeller-based perforator flaps performed in acute setting.

METHODS

Between 2019 and 2022, 94 Gustilo III fractures were admitted to our trauma center, and 28 were Gustilo IIIB fractures. Five patients were eligible for an immediate perforator-based propeller flaps reconstruction. The mean age of the patients was 33.8 years. All of them were male. One of them was a heavy smoker (15 cigarettes per day). No other comorbidities were present.

RESULTS

The mean operating time, including fracture reduction and fixation time, was 106 minutes. The length of the defect varied between 5 and 7 cm and the width between 3 and 4 cm. We reported no major complications, and none of the patients required a surgical revision of the flap. A patient with smoking habit reported a superficial flap necrosis. The mean follow-up was 5.5 months. No cases of nonunion or osteomyelitis have developed so far.

CONCLUSIONS

The use of perforator-based propeller flaps, in acute trauma setting, has not been reported in literature so far. In our experience, propeller perforator flaps are a viable reconstructive option in immediate reconstruction during the acute management of open fractures.

Composition of pathogenic microorganism in chronic osteomyelitis based on metagenomic sequencing and its application value in etiological diagnosis

BACKGROUND

Traditionally, conventional microbiological culture methods have been used to detect pathogenic microorganisms in chronic osteomyelitis. However, these methods have been found to have a low detection rate, complicating the precise guidance of infection treatment. This study employed metagenomic next-generation sequencing (mNGS) to detect these microorganisms in chronic osteomyelitis with three main objectives: 1). Gain a deeper understanding of the composition of pathogenic microorganisms in chronic osteomyelitis. 2). Compare the microbial detection rates between mNGS and the standard culture methods used in laboratories to enhance the effectiveness of the traditional culture methods. 3). Explore the potential of mNGS in etiological diagnosis.

METHODS

Fifty clinically confirmed intraoperative bone tissue samples of chronic osteomyelitis from January 2021 to December 2021 were collected and subjected to mNGS and microbiological testing, respectively. The orthopaedic surgeon combined clinical manifestations and related examinations to determine the causative pathogens.

RESULTS

The culture method obtained 29 aerobic and parthenogenic anaerobic bacteria, 3 specific anaerobic bacteria, and 1 yeast-like fungus. Thirty-six aerobic and parthenogenic anaerobic bacteria, 11 specific anaerobic bacteria, and 1 yeast-like fungus were obtained by mNGS, and 2 Mycobacterium tuberculosis(MTB) strains were detected. However, there was no significant difference in the overall positive detection rate between mNGS and the culture method (P = 0.07), and the two were not statistically significant in detecting aerobic and partly anaerobic bacteria (P = 0.625). But, mNGS was significantly superior to culture in detecting anaerobic bacteria and Mycobacterium tuberculosis (P<0.05).

CONCLUSIONS

The mNGS method has enhanced our understanding of the distribution of pathogenic microorganisms in chronic osteomyelitis. Traditional culture methods help isolate and cultivate aerobic and facultative anaerobic bacteria, and fungi, and are also utilized for antibacterial drug sensitivity tests. However, mNGS has shown superior capabilities in detecting anaerobic bacteria, MTB, and mixed infection bacteria. This finding offers invaluable guidance for improving laboratory microbial culture and detection conditions. Hence, mNGS should be judiciously used for chronic osteomyelitis, and PCR can be implemented for certain difficult-to-culture microorganisms, such as MTB.

Delays in Debridement of Open Femoral and Tibial Fractures Increase Risk of Infection

BACKGROUND

Infection remains a costly, devastating complication following the treatment of open fractures. The appropriate timing of debridement is controversial, and available evidence has been conflicting.

METHODS

This study is a retrospective analysis of the SIGN (Surgical Implant Generation Network) Surgical Database (SSDB), a prospective registry of fracture cases in predominantly low-resource settings. Skeletally mature patients (≥16 years of age) who returned for follow-up at any time point after intramedullary nailing of an open femoral or tibial fracture were included. Patients were excluded if they had delays in debridement exceeding 7 days after the injury. Utilizing a model adjusting for potential confounders, including patient demographic characteristics, injury characteristics, country income level, and hospital type and resources, local logistic regression analysis was performed to evaluate the probability of infection with increasing time to debridement in 6-hour increments.

RESULTS

In this study, 27.3% of patients met the eligibility criteria and returned for follow-up, with a total of 10,651 fractures from 61 countries included. Overall, the probability of infection increased by 0.17% for every 6-hour delay in debridement. On subgroup analysis, the probability of infection increased by 0.23% every 6 hours for Gustilo-Anderson type-III injuries compared with 0.13% for Gustilo-Anderson type-I or II injuries. The infection risk increased every 6 hours by 0.18% for tibial fractures compared with 0.13% for femoral fractures.

CONCLUSIONS

There was a linear and cumulative increased risk of infection with delays in debridement for open femoral and tibial fractures. Such injuries should be debrided promptly and expeditiously. The size and international nature of this cohort make these findings uniquely generalizable to nearly all environments where such injuries are treated.

Comparative Study of Linezolid and Vancomycin Regimens in One-Stage Surgery for Treating Limb Traumatic Osteomyelitis Caused by Methicillin-Resistant Staphylococcus aureus

To compare the clinical outcomes of linezolid and vancomycin regimens combined with one-stage surgery in treating traumatic osteomyelitis of the limbs caused by methicillin-resistant Staphylococcus aureus (MRSA) infection. A retrospective study was performed to analyze patients with traumatic osteomyelitis of the limbs attributable to MRSA infection. All of these patients received one-stage surgery to debride their wounds, with subsequent implantation of a vancomycin-loaded calcium sulfate artificial bone. Patients received either intravenous linezolid (study group) or vancomycin (control group) during the perioperative period. The postoperative inflammatory markers, renal function, duration of drainage catheter placement, duration of antibiotic administration, length of hospital stay, adverse events, and recurrence of osteomyelitis in these two groups were compared. The study group had a shorter duration of antibiotic administration and length of hospital stay (p < 0.05). There was a significant difference in the incidences of adverse events between the two groups (5.88% and 17.65% in the study and control groups, respectively, p < 0.05). There was no recurrence in either group during the three-year follow-up period. As of year, five after the surgery, one patient in the control group had a recurrence of osteomyelitis. The linezolid regimen should be preferred to the vancomycin regimen in patients with traumatic osteomyelitis of the extremities caused by MRSA infection because the linezolid regimen showed fewer adverse events, shorter periods of antibiotic use, and shorter hospital stay. However, both treatment regimens achieved satisfactory outcomes and warranted further investigations.

Modified Masquelet Technique and Primary Tibial Metaphyseal Shortening for the Management of Proximal Tibial-infected Non-union in a Patient with Alcohol-induced Neuropathy: A Case Study

Aim

To highlight the role of the Masquelet technique as a limb salvage procedure for a neuropathic patient presenting with infected non-union of proximal tibia.

Background

The management of an infected non-union in neuropathic patients is most challenging; with various treatment options available, the prognosis is often guarded.

Case description

A 37-year-old male with chronic polyneuropathy, also possessing a contralateral midfoot Charcot arthropathy secondary to a history of alcohol abuse, developed infection after a proximal tibial osteotomy for a preceding mal-non-union of a proximal tibia fracture. The management included hardware removal, excision of necrotic bone, interim insertion of antibiotic-loaded bone cement followed by an acute shortening and revision of the internal fixation utilising a second surgical incision. Successful bone union and eradication of infection was achieved and maintained after 13 months follow-up.

Conclusion

A successful outcome was achieved for an infected non-union of a long bone in a neuropathic patient using the Masquelet technique which was then followed with a second-stage removal of the spacer and shortening. By performing the revision ORIF surgery utilising a different skin incision in the setting of complicated previous surgical scars proved to be a viable technique towards reducing risk of recurrence of infection and a good outcome.

Clinical significance

Utilisation of the Masquelet technique and limb shortening in a staged manner for the management of long bone infections in neuropathic patients has not been reported before and may be valuable in such demanding clinical situations.

Clinical effectiveness of early internal fixation combined with free flap technique in the treatment of Gustilo IIIB open forearm fracture

INTRODUCTION

Gustilo IIIB open forearm fractures are severe injuries often associated with extensive bone and soft tissue injuries. The treatment of Gustilo IIIB open forearm fractures remains a challenging problem, with a high morbidity rate such as infection, nonunion, even amputation. External fixation is preferred for open lower limb fractures. However, there are significant differences between open bone injuries of the upper and lower extremity in terms of treatment plans. Use of internal fixation methods for open fractures is a controversial issue, as it requires early coverage of skin and soft tissue defects after radical debridement and irrigation. The optimal approach for open forearm fractures remains to be determined. The present study evaluated whether early internal fixation combined with free flap placement is effective for the treatment of Gustilo IIIB open forearm fracture.

HYPOTHESIS

Early internal fixation combined with the free flap technique in the treatment of Gustilo IIIB open forearm fracture provides good consolidation results.

MATERIAL AND METHODS

From January 2015 to January 2020, 20 patients with Gustilo IIIB open forearm fracture treated with early internal fixation combined with free skin flap placement were retrospectively analyzed. There were 9 males and 11 females, with an average age of 40 years. In all cases, the injuries were classified as Gustilo type IIIB. The area of the wounds ranged from 9×3cm to 27×10cm. Fist-stage plate fixation was adopted in 16 cases. Four patients presenting with major contamination received first-stage fixation with Kirschner wires and external fixation, and the second-stage surgery of surgical treatment included flap placement and internal fixation within 10 days. The rates of limb salvage and complications were recorded. The Anderson scoring system was utilized to assess limb function.

RESULTS

Limb salvage was successful in all 20 cases. The average length of hospital was 19 days (range, 7-28 days). Four patients developed superficial infections. After debridement, the wounds were covered with skin grafts. No deep infections or osteomyelitis occurred. Three patients developed nonunion, and bone grafts achieved bone healing later. The donor skin flaps healed well, with partial pigmentation. No complete necrosis of the flaps occurred. Only the distal part of flaps became necrotic in two cases, which were then successfully treated by debridement and skin grafting. The average follow-up duration was 14.7 months (range, 8-24 months). According to the Anderson scoring system, 7 cases were graded as excellent, 6 cases as good, 5 cases as fair, and 2 cases as poor.

CONCLUSION

For Gustilo IIIB type injuries, early and thorough debridement along with early internal fixation and skin flap coverage of the wound can achieve satisfactory clinical results, shorten the treatment cycle, and maximize limb function recovery.

New insights in lower limb reconstruction strategies

High Energy Musculoskeletal Traumas (HEMTs) represent a relevant problem for healthcare systems, considering the high social costs, and both the high morbidity and mortality. The poor outcomes associated with HEMT are related to the high incidence of complications, including bone infection, fracture malunion and non-union. The treatment of each of these complications could be extremely difficult. Limb reconstruction often needs multiple procedures, rising some questions on the opportunity in perseverate to try to save the affected limb. In fact, theoretically, amputation may guarantee better function and lower complications. However, amputation is not free of complication, and a high long-term social cost has been reported. A comprehensive literature review was performed to suggest possible ways to optimize the limb preservation surgeries of HEMT's complications in order to ameliorate their management.

Predictive factors for fracture-related infection in open tibial fractures in a Sub-Saharan African setting

INTRODUCTION

The management of open tibial fractures (OTF) is challenging in low and middle-income countries (LMICs) where appropriate human resources and infrastructure (including equipment, implants and surgical supplies) are not readily available and medical care is not readily accessible. OTF are not rarely associated with a subsequent fracture-related infection (FRI), which is one of the most devastating and difficult to cure complications in orthopaedic trauma care. The aim of this study was to determine the rate and the predictive factors of FRI in OTF in a limited-resource setting of sub-Saharan Africa.

METHODS

Patients with OTF who underwent surgery from July 2015 to December 2020 and followed-up for at least 12 months in a tertiary care teaching hospital in Yaoundé (Cameroon) were retrospectively investigated. Diagnosis of FRI was based on the confirmatory criteria of the International FRI Consensus definition. All patients with bone infections, occurring at any time point during follow-up, were included. Logistic regression was used to determine the predictive factors for FRI.

RESULTS

One hundred and five patients with OTF were studied. With a mean follow-up period of 29.5 ± 16.6 months, 33 patients (31.4%) presented with FRI. Gustilo-Anderson type of OTF, compliance with antibiotics, blood transfusion, time to first washing of the wounds and method of bone fixation were factors associated with the occurrence of FRI. In multivariable logistic regression, 6-hours delay to first washing of the wounds (OR=8.07, 95% CI: 1.43-45.31, p = 0.01), and compliance with antibiotics (OR=11.33, 95%CI: 1.11-115.6, p = 0.04) were the only independent predictors of FRI.

CONCLUSION

The overall rate of FRI in open tibial fracture is still high in the sub-Saharan African context. For similar low-resources settings, this study supports the recommendations (1) to perform a very early washing-dressing-splinting of OTF on admission of the patient, (2) to administer antibiotics early, and (3) to perform surgery as soon as reasonably possible, once appropriate personnel, equipment, implants and surgical supplies are available.

The Effect of Timing of Debridement and Surgical Intervention in Open Fractures on the Rate of Infection and Surgical Outcomes: A Prospective Study in a Tertiary Care Setup

Introduction Open fractures remain one of the true orthopedic emergencies. Despite recent advances in orthopedic surgery, the management of compound fractures is still a challenge to an orthopedic surgeon. Open fractures are a result of high-speed injuries and are associated with several complications such as infections, non-unions, or sometimes an eventual amputation. Infection is the major problem associated with open fractures due to soft tissue damage, contamination, and neurovascular compromise. Presently, management of open fractures requires early aggressive debridement followed by limb salvage by definitive reconstruction or amputation, depending upon the extent and location of the injury. Early aggressive debridement of open fractures has always been the rule. However, it has been observed that open fractures managed even after six hours of injury fare well, and there are no definite guidelines available to decide the safe period of debridement following open fractures so as to prevent infection. The "six-hour rule" is a hotly debated topic with fervent perseverance of this dogma despite a gross lack of support from the literature. Objective The objective of this study was to analyze the relationship between the timing of operation/debridement on infection rates in open fractures, particularly if surgery is performed after six hours. Methods This is a prospective study of 124 patients (R=5-75 years) presenting with open fractures to the outpatient department (OPD) and emergency section of a tertiary care hospital from January 2019 to November 2020. Patients were divided into four groups based on the time to operation/debridement: groups A, B, C, and D, with patients operated within six hours, six to 12 hours, 12-24 hours, and 24-72 hours after injury, respectively. Infection rates were obtained based on the above data. ANOVA was applied using SPSS 20 software (IBM Inc., Armonk, New York). Results This study concludes that the infection rate for fractures treated in less than six hours was 18.75%; in the six to 12 hours group, it was 18.50%, and in the 12-24 hours group, it was 14.28%. The infection rate increased to 38.8% if surgery was performed after 24 hours of injury. On statistical analysis, the time to debridement was not found to be a significant factor. The infection rate in Gustilo-Anderson classification compound grade I was 2.7%, grade II 9.8%, grade IIIA 45%, and grade IIIB 61%. Also, in this study, the union rate in grade I was 97.22%, grade II 96.07%, grade IIIA 85%, and grade IIIB 66.66%. Thus, the degree of wound contamination and compounding gives a prognostic indication regarding the final outcome of the compound fracture. Conclusion Time to debridement is not a significant factor in the management of compound fractures, and these fractures can be safely debrided up to 24 hours after injury. Gustilo and Anderson's classification provides a prognostic indicator of the outcome of a compound fracture. Infection rates and non-union rates increase with increasing grades of compound fractures.

Infection after surgical implant generation network (SIGN) nailing in treatment of long bone shaft fractures in Ethiopia: analysis of a 4-year results

BACKGROUND

One of the challenge to manage long bone fracture is the risk of infection. Intramedullary nailing is the standard treatment of long bone shaft fractures. Infection from the surgical site during orthopedic management is posing postoperative burdens in different perspectives like patient perspectives and healthcare facilities. However, there is limited information on the magnitude of infection in Ethiopia after surgical implant generation network (SIGN) nailing in the treatment of long bone shaft fractures. Therefore, the current study aimed to assess the prevalence of infection in patients with long bone shaft fractures treated with surgical implant generation network (SIGN) nailing.

OBJECTIVE

To assess prevalence of infection in patients with long bone shaft fractures treated with SIGN nailing at Felege Hiwot Referral Hospital from January 1, 2015, to December 31, 2018, Bahir Dar, Northwest, Ethiopia.

METHODS

This was a retrospective study over a period of 4 years. SIGN surgical-related data, presence or absence of infection from the documented information were collected from the chart/the source. The types of infection were also collected with the standard classification as superficial, deep and deep with osteomyelitis. Age, sex, fracture pattern, nature of fracture, mechanism of injury, prophylaxis antibiotics, nail type, follow-up in weeks and other factors were also extracted from the patients' charts with structured checklist. Data were analyzed with statistical package for social sciences (SPSS) version 23. The analyzed data were presented with texts, tables and a graph.

RESULTS

Three hundred and eighty-two long bone fractures were treated by locked SIGN intramedullary nailing during the study period. After screening the inclusion criteria, a total of 311 cases were included in this study. A total of 13 (4.2%) patients who treated with SIGN intramedullary nailing developed infection.

CONCLUSIONS

We conclude that the overall prevalence of infection with SIGN intramedullary nailing is almost similar with the surgeries done in the developed countries.

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.

Complex Orthopaedic Trauma Is Shifting Away From Level I to Non-Level I Trauma Centers: An Analysis of the National Trauma Data Bank

INTRODUCTION

An increasing number of fellowship-trained orthopaedic trauma surgeons are working in non-Level I centers. This study aimed to examine trends of management of complex orthopaedic trauma in Level I centers versus non-Level I centers and its potential effect on patient outcomes.

METHODS

Data from the National Trauma Data Bank from 2008 to 2017 were analyzed. Non-Level I to Level I center ratios for complex fractures and complication rates, median hours to procedure for time-sensitive fractures, and uninsured/underinsured rates of Level I and non-Level I centers were recorded.

RESULTS

Three hundred one thousand patients were included. A statistically significant downward trend was identified in the percent of all complex orthopaedic trauma at Level I centers and per-hospital likelihood of seeing a complex orthopaedic fracture in a Level I versus non-Level I hospital. Per-hospital complication rates were consistently lower in non-Level I hospitals after controlling for injury severity and payer mix. Time-sensitive fractures were treated earlier in non-Level I centers.

DISCUSSION

This study demonstrates a reduction of complex trauma treatment in Level I centers that did not translate to adverse effects on patient outcomes. Policymakers should notice this trend to ensure the continued quality of orthopaedic trauma training and maintenance of expertise in complex fracture management.

Evidence for Local Antibiotics in the Prevention of Infection in Orthopaedic Trauma

Prevention of fracture-related infection (FRI) remains a substantial challenge in orthopaedic trauma care. There is evolving evidence to support the use of local antibiotics for both the prevention and treatment of musculoskeletal infection. Local antibiotics can achieve higher local tissue concentrations with a lower risk of systemic complications compared to intravenously administered antibiotics. These antibiotics may be administered in powder or liquid form without carrier, or if sustained release is desired, using a carrier. Polymethylmethacrylate (PMMA), ceramics, and hydrogels are examples of antibiotic carriers. Unlike PMMA, ceramics and hydrogels have the advantage of not requiring a second surgery for removal. The VANCO trial supported the use of powdered vancomycin in high-risk fracture cases for the reduction of Gram-positive infections; although, data is limited. Future studies will evaluate the use of aminoglycoside antibiotics to address Gram-negative infection prevention. While theoretical concerns exist with the use of local antibiotics, available studies suggest local antibiotics are safe with a low-risk of adverse effects.

Short term results with the use of PLA antibiotic coated nail in open tibia fractures: A prospective study

Background

Antibiotic impregnated cement coated nails have been described in literature with promising success rates. However, they need removal at a later stage. This study focuses on use of a PLA-precoated antibiotic nail that stops eluting antibiotic after a while and can be retained later as it behaves as a standard interlocking nail in the long run.

Purpose

To study if PLA (polylactic acid) -antibiotic coated nails reduces infection and non-union rates and improve the functional outcome in open tibial shaft fracture cases.

Materials and methods

In this prospective cohort study, we included 54 patients with open tibia shaft fractures treated with wound debridement and internal fixation using a reamed PLA (polylactic acid)-antibiotic coated nail (CE-certified, OSSIPRO, MatrixTM).

Results

Forty patients with a Grade 2 and ten with grade 3A open tibial fracture, according to the Gustilo-Anderson classification, completed a minimum of six months of follow-up and were included in the analysis. At the final follow-up, four patients (all with grade 3A fracture) had an active infection, 10 (four of grade 2 and six of grade 3A) had non-union, the mean physical component score (SF-36 score) was 55.2 ± 20.10 (grade 2; 58.95 ± 9.99, grade 3A; 40.19 ± 16.37, P value 0.002), and the mean mental component score (SF-36 score) was 54.96 ± 23.5 (grade 2; 57.96 ± 16.63, grade 3A; 42.94 ± 23.75, P value 0.04). Furthermore, Multivariate analysis showed age and grade of fracture to be independently related to the development of infection and non-union.

Conclusion

Although the use PLA-antibiotic coated nail looks promising, short-term results have revealed no additional benefit in terms of reduced infection rates, improved union rates or functional outcomes. Large multicentric randomized controlled trials and a long term follow up are advised to further explore the role of PLA coated antibiotic nails in open tibial fractures.

Patient Comorbidities Associated With Acute Infection After Open Tibial Fractures

INTRODUCTION

Open tibial shaft fractures are high-risk injuries for developing acute infection. Prior research has focused on injury characteristics and treatment options associated with acute inpatient infection in these injuries without primary analysis of host factors. The purpose of this study was to determine the patient comorbidities associated with increased risk of acute infection after open tibial shaft fractures during initial hospitalization.

METHODS

A total of 147,535 open tibial shaft fractures in the National Trauma Data Bank from 2007 to 2015 were identified that underwent débridement and stabilization. Infection was defined as a superficial surgical site infection or deep infection that required subsequent treatment. The International Classification of Diseases, ninth revision codes were used to determine patient comorbidities. Comparative statistical analyses including odds ratios (ORs) for patient groups who did develop infection and those who did not were conducted for each comorbidity.

RESULTS

The rate of acute inpatient infection was 0.27% with 396 patients developing infection during hospital management of an open tibial shaft fracture. Alcohol use (OR, 2.26, 95% confidence interval [CI], 1.73-2.96, P < 0.0001), bleeding disorders (OR, 4.50, 95% CI, 3.13-6.48, P < 0.0001), congestive heart failure (OR, 3.25, 95% CI, 1.97-5.38, P < 0.0001), diabetes (OR, 1.73, 95% CI, 1.29-2.32, P = 0.0002), psychiatric illness (OR, 2.17, 95% CI, 1.30-3.63, P < 0.0001), hypertension (OR, 1.56, 95% CI, 1.23-1.95, P < 0.0001), obesity (OR, 3.05, 95% CI, 2.33-3.99, P < 0.0001), and chronic obstructive pulmonary disease (OR, 2.09, 95% CI, 1.51-2.91, P < 0.0001) were all associated with increased infection rates. Smoking (OR, 0.957, 95% CI, 0.728-1.26, P = 0.722) and drug use (OR, 1.11, 95% CI, 0.579-2.11, P = 0.7607) were not associated with any difference in infection rates.

DISCUSSION

Patients with open tibial shaft fractures who have congestive heart failure, bleeding disorders, or obesity are three to 4.5 times more likely to develop an acute inpatient infection than patients without those comorbidities during their initial hospitalization. Patients with diabetes, psychiatric illness, hypertension, or chronic obstructive pulmonary disease are 1.5 to 2 times more likely to develop subsequent infection compared with patients without those comorbidities. Patients with these comorbidities should be counseled about the increased risks. Furthermore, risk models for the infectious complications after open tibial shaft fractures can be developed to account for this more at-risk patient population to serve as modifiers when evaluating surgeon/hospital performance.

CONCLUSION

Patient comorbidities are associated with increased risk of acute inpatient infection of open tibial shaft fractures during hospitalization.

Factors associated with delays in medical and surgical open facial fracture management

Objectives

Open fractures are at risk of infection because of exposure of bone and tissue to the environment. Facial fractures are often accompanied by other severe injuries, and therefore fracture management may be delayed until after stabilization. Previous studies in this area have examined timing of multiple facets of care but have tended to report on each in isolation (eg, antibiotic initiation).

Methods

This was a retrospective study of adult patients admitted to five trauma centers from January 1, 2017 to March 31, 2021 with open facial fractures. Variables collected included demographics, injury mechanism, details on facial and non-facial injuries, facial fracture management (irrigation and debridement (I&D), irrigation without debridement, open reduction internal fixation (ORIF), antibiotics), and other hospital events. The study hypothesized that the presence of serious non-facial injuries would be associated with delays in facial fracture management. The primary aims were to describe open facial fracture management practices and examine factors associated with early versus delayed fracture management. A secondary aim was to describe infection rates. Early treatment was defined as within 24 hours of arrival for I&D, irrigation without debridement, and ORIF and within 1 hour for antibiotics.

Results

A total of 256 patients were included. Twenty-seven percent had major trauma (Injury Severity Score ≥16). The presence of serious head injury/traumatic brain injury was associated with delayed I&D (OR_early=0.04, p<0.01), irrigation without debridement (OR_early=0.09, p<0.01), and ORIF (OR_early=0.10, p<0.01). Going to the OR within 24 hours was associated with early I&D (OR_early=377.26, p<0.01), irrigation without debridement (OR_early=13.54, p<0.01), and ORIF (OR_early=154.92, p<0.01). The infection rate was 4%.

Conclusions

In this examination of multiple aspects of open facial fracture management, serious injuries to non-facial regions led to delays in surgical fracture management, consistent with the study hypothesis.

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.

Definitive fixation of open tibia fractures: Does reopening the traumatic wound increase complication rates?

BACKGROUND

It is unknown if surgical approach or use of previous traumatic wounds for open fracture instrumentation has an impact on patient complications or outcomes. This study sought to compare infection and nonunion rates in the staged treatment of open tibia fractures where the traumatic wound was reopened during definitive fixation versus when they were not.

METHODS

A retrospective review was performed on all patients at a single institution level 1 trauma center. All patients who had a minimum of 1 year clinical and radiographic outcomes were included. Primary outcome measures were incidence of infection and nonunion. Groups of patients were compared based on surgical approach for definitive fixation.

RESULTS

A total of 96 patients were included - 48 patients received definitive treatment and wound closure during initial management of the open fracture (group 1), 22 patients had staged fixation through new incisions (group 2), and 26 patients had their traumatic wound reopened during definitive fixation (group 3). Rates of infection were 10.4%, 31.8% and 11.5% respectively (p = 0.15). Rates of nonunion were 20.8%, 27.3% and 30.8% (p = 1.0). No statistically significant differences in regards to primary outcomes were found between the staged fixation groups. Multiple logistic regression also showed no difference in infection or nonunion when controlling for known risk factors.

CONCLUSION

For open tibia fractures that underwent staged fixation, no significant differences in infection or nonunion were observed between procedures that involved reopening the traumatic wound versus procedures performed through new incisions. The presence of a distal tibia periarticular fracture was found to be independently associated with infection risk.

Epidemiologic characteristics and pre-hospital care of traumatic injuries during the COVID-19 pandemic in an emerging and developing country: A single tertiary centre experience

BACKGROUND

Pre-hospital care has been shown to reduce the mortality in trauma patients. The present study is an attempt to identify the status of pre-hospital orthopaedic trauma care in developing countries during COVID-19 pandemic.

METHODS

This was a prospective observational study carried out in a tertiary care setup from March 25th^, 2020 to January 31st^, 2021. All the data pertaining to the traumatic injuries including demographic details and epidemiologic characteristics were recorded in an electronic database.

RESULTS

A total of 1044 patients were included in the study for evaluation. The mean age was 35.24 ± 19.84 years. There were 873 males and 171 females. A total of 748 presented from nearby states, with 401 being the referrals and 347 cases coming directly to hospital. A total of 141 open fractures presented directly and 269 were referred from nearby states. Out of 269 cases of open fractures, only 67 and 139 were given intravenous antibiotics and had wound dressing done respectively at the periphery site. A total of 125, 112, 92 and 84 patients were received without traction/splintage, intravenous fluids, dose of analgesics and recording of vitals respectively. Delay from injury to presentation in emergency/administration of antibiotic (Hours) was 7.06. Road side accidents were main cause comprising of 52.58% cases. Gustilo Anderson classification grade-2 comprised of majority of the open fractures (51.63%). Lower limb fractures comprised of majority of the injuries (70.59%). Majority were adults and conservative management was the most common mode of treatment. A total of 197 and 265 patients had associated head injuries and blunt trauma chest/blunt trauma abdomen respectively.

CONCLUSION

Emphasizing on pre-hospital care measures, with special focus on co-ordination between primary, secondary and tertiary health care facilities is the need of the hour and can prevent additional morbidities, avoiding overburden of the already compromised healthcare centres.

Concepts in wound irrigation of open fractures: 'Where we came from, and where are we now?

Wound irrigation is described as the flow of a solution through an exposed fracture surface to reduce the microbial colonization, to remove apparent foreign particles and wound exudates. . While recent literature and various in-vitro and in-vivo trials have cleared some clouds of doubt from the mind, it still remains a topic of debate. Normal saline remains the standard irrigation solution as it is non tissue toxic and has the same tonicity as body fluids. The quantity and duration of washing though is not standardized and is the surgeon's choice. This adds to the dilemma in the minds of the surgeon, with the timing of the debridement and the duration of wound irrigation depending on the surgeon's discretion. Future studies should aim to regulate the duration of the wound irrigation besides guiding about the ideal fluid volume to be used for the irrigation. Further, secondary end-points like the duration of hospital stay, rate of infections and use of hospital resources, should be computed to know about the adequacy of the wound debridement and irrigation. Antimicrobial solutions can kill microorganisms in the wound but are toxic to the host tissues as well, which limits their use. In addition, pulsatile (high pressure) lavage has not been seen to increase overall effectiveness. Recent research trials have found cumulative use of innovative solutions like phenols and EDTA along with enzymes to be encouraging though large randomized controlled trials are lacking.

A Simple Initiative to Decrease Time to Antibiotic Prophylaxis for Open Fractures Is Durable After 2 Years

INTRODUCTION

A simple antibiotic prophylaxis initiative can effectively decrease the time to antibiotic administration for patients with open fractures. We aim to determine whether adherence to the protocol decreased over time without active input from the orthopaedic trauma team.

PATIENTS AND METHODS

This retrospective cohort study included adult patients with open fractures (excluding hand) presenting directly to the emergency department at one Level I trauma center. Three separate 50-patient groups were included: a preimplementation cohort, immediately postimplementation cohort, and a retention cohort 2 years later. The primary outcome was time from emergency department presentation to antibiotic administration, and secondary outcomes were the percentage of patients receiving antibiotics within 60 minutes and incidence of infection requiring revision surgery within 90 days. The χ2 and Student t-tests evaluated between-group differences, and multivariable linear or logistic regression evaluated risk factors.

RESULTS

After implementation, the time from presentation to antibiotic administration decreased markedly from 123.1 to 35.7 minutes and remained durable (50.0 minutes) at retention. The proportion of patients receiving antibiotics within 60 minutes increased markedly from 46% preimplementation to 82% postintervention and remained similar at retention (80%). The postintervention and retention groups were markedly more likely to receive antibiotics within 60 minutes than the preintervention group (odds ratio [OR], 8.4 and 4.7, respectively), as were patients with a higher Gustilo-Anderson type (OR, 2.4/unit increase), lower extremity injury (OR, 2.8), and male sex (OR, 3.1); mechanism, age, and Injury Severity Score were not associated. No difference was observed in infection.

CONCLUSIONS

Our educational initiative showed durable results in reducing the time from presentation to antibiotic administration after 2 years.

Open tibial fractures: An overview

Open tibial fractures are complex injuries with multifactorial outcomes and variable prognosis. The close proximity of the tibia to the skin makes it prone to extensive soft tissue damage and subsequent detrimental complications, such as infection and non-union. Thus, they were historically associated with high rates of amputation, sepsis, or even death. The advancement of surgical instruments and techniques, along the emergence of evidence-based guidance, have resulted in a significant reduction in complications. Peculiarly though, modern management strategies have a strong foundation in practices described in the ancient times. Nevertheless, post-operative complications are still a challenge in the management of open tibial fractures. Efforts are actively being made to refine the surgical approaches used, while noteworthy is the emergence of the Orthoplastic approach. The aim of this review is to summarise and discuss the historical perspective of the management of open tibial fractures, their epidemiology and classification, up-to-date principles of surgical management and outcomes following injury.

Evolution in the Acute Management of Open Fracture Treatment? Part 2

INTRODUCTION

In the first installment of this two-part series, we explored the history of open fracture treatment focusing primarily on bacteriology and antibiotic selection/stewardship. In this follow-up segment, we will analyze and summarize the other aspects of open fracture care such as time to debridement, pulsatile lavage, and open wound management (including time to closure)-finishing with summative statements and recommendations based on the current most up-to-date literature.

Gaps in the Care of Open Fractures: An Indian Scenario

BACKGROUND/PURPOSE

There is a distinct lack of published studies evaluating the reasons for delay in definitive treatment of open fractures. This study aimed to determine the specific factors causing delay in the timely treatment of open fractures from the time of injury and to analyse the quality of treatment performed at the pre-hospital level.

METHODS

In total, 250 consecutive patients with open fractures were assessed for time to surgery from injury and admission. The referred patients were analysed for distance of travel, level of referring hospital and appropriateness of care. The reasons for delay in terms of infrastructural- and patient-related factors were analysed individually and in combination.

RESULTS

There were 37 direct patients (Group A) and 213 referred patients (Group B). Inappropriate care was present in 172 out of 213 (80.8%) referred patients. In total, 84% patients travelled more than 50 kms. The definitive surgery in referred patients was likely to be significantly delayed with regard to time from injury (29.84 vs 44.84 h, p ≤ 0.02). After admission, the time to surgery was greater than 24 h in 102 patients. Multivariate regression analysis determined that associated injuries and lack of fitness for surgery caused greater delay than non-availability of operation theatre or intensive care unit bed.

CONCLUSION

Delayed referral, inadequate pre-hospital care and delay in surgery due to patient- and infrastructural-related issues at tertiary centre were identified as critical gaps in open fracture care in India. The importance of appropriate basic knowledge about management of open fractures should be emphasized at all structural level of care.

National Metrics Improved Timeliness of Antibiotic Administration for Open Extremity Fractures

INTRODUCTION

Antibiotics have been shown to be an essential component in the treatment of open extremity fractures. The American College of Surgeons' Trauma Quality Improvement Program, based on a committee of physician leaders including orthopaedic trauma surgeons, publishes best-practice guidelines for the management of open fractures. Accordingly, it established the tracking of antibiotic timing as a metric with a plan to use that metric before trauma center site reviews. Our hypothesis was that this physician-led effort at the national level would provide the necessary incentive to effect change within our institution.

METHODS

A retrospective review of all patients treated at our institution for open extremity fractures was performed over 3 periods separated by 2 quality initiatives. The first initiative was an institution-driven effort to increase awareness and educate specific departments about the importance of prompt antibiotic administration. The second initiative was the tracking of antibiotic order and administration times with quarterly audits following newly published guidelines.

RESULTS

Neither antibiotic order placement within 1 hour nor administration within 1 hour improved after our first institution-specific initiative. Both outcome measures significantly improved after the second quality initiative, as did median times from arrival to antibiotic order and administration.

CONCLUSIONS

Metrics developed and measured by a physician-led national organization led to practice changes at our hospital. Tracking of antibiotic timing for open fracture treatment was more effective than institutional education of healthcare providers alone. This study suggests that nationally published guidelines, developed and measured by physician leaders, will be found to be relevant by other physicians and can be a powerful tool to drive change.

Outcomes following the delayed management of open tibial fractures

AIMS

National guidelines set standards for the definitive management of open fractures within 72 h. This study aims to investigate our outcomes where this timeline was unachievable for most cases due to a split-site orthoplastic service.

PATIENTS & METHODS

116 consecutive Gustilo-Anderson grade IIIB & IIIC open tibial fractures presenting to our major trauma centre (MTC) between September 2012 and April 2018 were reviewed. The mean follow up was 46 months (17 to 88). 110 (95%) were grade IIIB and 6 (5%) grade IIIC. The most common injury mechanism included road traffic accidents (59%) and falls (28%). Primary outcomes were recorded according to; timing of initial debridement and definitive cover, rates of superficial and deep infection, non-union and amputation. Subgroups were statistically analysed according to time to initial debridement, definitive soft-tissue cover and injury severity score (ISS).

RESULTS

The mean time to initial debridement was 11.3 h (2.9 to 38.9) and definitive soft-tissue cover 9.9 days (0 to 37). We recorded rates of: superficial infection; 42 cases (36%), deep infection; 14 cases (12%) and non-union requiring revision; 19 cases (16%). There were 20 amputations (17%) with 9 (8.6%) performed early and 11 (9.5%) delayed. Subgroup analysis showed higher rates of superficial infection (50%, p = 0.002) and amputation (26.6%, p = 0.01) for those debrided <12 h. A greater presenting ISS related to a delay to definitive cover >7 days (p = 0.05). Primary outcomes trended worse for those covered >7 days but did not reach significance.

CONCLUSION

Major trauma patients are particularly vulnerable to poor outcomes resulting from the delay in definitive management of open fractures. MTC's need resources and a co-located orthoplastic service to achieve national standards and better outcomes. Current guidelines do not advise for the management of patients where a delay in definitive surgery is anticipated.

Infection after Open Long Bone Fractures: Can we Improve on Prophylaxis?

INTRODUCTION

Current standards recommend antibiotic prophylaxis administered after open fracture injury. The purpose of this study was to assess culture results in patients with open fracture-associated infections, hypothesizing that cultures obtained do not vary by Gustilo-Anderson (GA) classification.

METHODS

We examined cultured bacterial species from patients with open long bone fractures that underwent irrigation and debridement at a Level 1 trauma center (2008-2016), evaluating our current and two hypothetical antibiotic protocols to assess whether they provided appropriate coverage. The antibiotic protocols included protocols 1 (cefazolin, with gentamicin added for type III fractures), 2 (vancomycin and cefepime) and 3 (ceftriaxone).

RESULTS

GA classification was not associated with bacterial gram stain (P = 0.161), nor was it predictive of mono- versus polymicrobial infection (P = 0.094). Of 42 culture-positive infections, 31 were type III and 11 were type I or II fractures. 27% of the infections for type I or II fractures were caused by organisms targeted by protocol 1 (OR 0.18, 95% CI 0.04-0.82; P = 0.027). There was no difference in coverage by fracture type among protocol 2 (P = 0.771) or protocol 3 (P = 0.891). For type III fractures, protocol 2 provided 94% appropriate coverage compared to 68% and 61% coverage by protocols 1 and 3, respectively.

CONCLUSION

For open fractures complicated by infection, isolated bacterial organisms do not correlate with GA open fracture classification, suggesting that hypothetical protocol 2 should be used for all fracture types. Protocol 2's broad coverage, across all GA fracture types, may prevent infection by organisms not covered by current antibiotic prophylaxis.

[Open fractures]

Open fractures are associated with a higher rate of infections and delayed fracture healing; therefore, in addition to fracture fixation, infection prevention and soft tissue management are also important. Administration of antibiotics should be carried out as early as possible and over 24-72 h depending on the injury. The initial debridement and assessment of the severity of injury determine the treatment strategy. Fracture fixation follows the general traumatological principles. Simple injury patterns can be treated by primary fixation and wound closure. With substantial contamination, loss of bone or extensive soft tissue damage, temporary fixation and temporary wound closure are carried out. The definitive treatment with soft tissue coverage should be performed within 72 h in order to reduce the risk of fracture-related infections. For osseous segmental defects, different approaches are available to restore bone continuity, depending on the size and soft tissue situation.

Can Open Hand Injuries Wait for Their Surgery in a Tertiary Hospital?

Objective  Open hand injuries are routinely admitted and planned for surgery acutely, competing with other surgical emergencies. This retrospective study aims to evaluate if a delay in timing to surgery for open hand injuries led to an increased rate of infection. Materials and Methods  All patients who sustained open hand injuries and underwent semi-emergent day surgery from January 1, 2015 to December 31, 2016 were included. Outcome of postoperative infection was analyzed against demographic data, injury details, and delay from trauma to therapy. Results  There were 232 cases (91% males) included, with 92.0% performed under local anesthesia. Deep seated postoperative infection was seen in 1.3%, which was not significantly associated with delay to surgery. Conclusion  We had comparable infection rates as compared with published literature. Delayed timing of surgical treatment in open hand injuries was not associated with increased rates of deep-seated infection. Managing open hand injuries as semi-emergent surgeries may be acceptable given the low infection rates.

Delayed debridement of open tibia fractures beyond 24 and 48 h does not appear to increase infection and reoperation risk

PURPOSE

Surgical debridement is critical to the treatment of open tibia fractures, although the effects of delayed debridement have not been well-established. Other factors such as Gustilo-Anderson type, prompt initiation of antibiotics, and time to definitive closure may be more predictive of infection than time to surgery. We sought to determine the effect of a prolonged delay to surgical debridement with respect to infection and reoperation rates for open tibia fractures.

METHODS

All open diaphyseal tibia fractures with > 12-week follow-up were evaluated. Patient demographics, Gustilo-Anderson type, and rates of deep infection and all-cause reoperation were recorded. Patients were divided into 3 groups based on time to surgery: early (< 24 h), delayed (24-48 h), and late (> 48 h). Univariate and multivariate analyses were performed to evaluate the relationship between time to surgery, fracture type, infection, and reoperation.

RESULTS

In total, 96 open tibia fractures with average follow-up of 59.3 weeks and infection rate of 13.5% were included. Infection rates for the early, delayed, and late groups were 13.3%, 17.2%, and 9.1%, respectively (p = 0.70). Reoperation rates for the early, delayed, and late groups were 29.8%, 31.0%, and 22.7%, respectively (p = 0.80). The groups did not vary in proportion of Gustilo-Anderson fracture types; infection rates between Gustilo-Anderson types were similar (p = 0.57). Type IIIA-C fractures required more reoperations than other fracture types (p = 0.01).

CONCLUSION

Delayed surgical debridement of open tibia fractures did not result in greater rates of infection or reoperation. Gustilo-Anderson classification was more predictive of reoperation, with Type IIIA-C injuries having a significantly higher reoperation rate.

The effect of time to irrigation and debridement on the rate of reoperation in open fractures : a propensity score-based analysis of the Fluid Lavage of Open Wounds (FLOW) study

AIMS

Despite long-standing dogma, a clear relationship between the timing of surgical irrigation and debridement (I&D) and the development of subsequent deep infection has not been established in the literature. Traditionally, I&D of an open fracture has been recommended within six hours of injury based on animal studies from the 1970s, however the clinical basis for this remains unclear. Using data from a multicentre randomized controlled trial of 2,447 open fracture patients, the primary objective of this secondary analysis is to determine if a relationship exists between timing of wound I&D (within six hours of injury vs beyond six hours) and subsequent reoperation rate for infection or healing complications within one year for patients with open limb fractures requiring surgical treatment.

METHODS

To adjust for the influence of patient and injury characteristics on the timing of I&D, a propensity score was developed from the dataset. Propensity-adjusted regression allowed for a matched cohort analysis within the study population to determine if early irrigation put patients independently at risk for reoperation, while controlling for confounding factors. Results were reported as odds ratios (ORs), 95% confidence intervals (CIs), and p-values. All analyses were conducted using STATA 14.

RESULTS

In total, 2,286 of 2,447 patients randomized to the trial from 41 orthopaedic trauma centres across five countries had complete data regarding time to I&D. Prior to matching, the patients managed with early I&D had a higher proportion requiring reoperation for infection or healing complications (17% vs 13%; p = 0.019), however this does not account for selection bias of more severe injuries preferentially being treated earlier. When accounting for propensity matching, early irrigation was not associated with reoperation (OR 0.71 (95% CI 0.47 to 1.07); p = 0.73).

CONCLUSION

When accounting for other variables, late irrigation does not independently increase risk of reoperation. Cite this article: Bone Joint J 2021;103-B(6):1055-1062.

The Effect of Delayed Surgical Debridement in the Management of Open Tibial Fractures: A Systematic Review and Meta-Analysis

Introduction: Open tibial fractures are complex injuries with variable outcomes that significantly impact patients’ lives. Surgical debridement is paramount in preventing detrimental complications such as infection and non-union; however, the exact timing of debridement remains a topic of great controversy. The aim of this study is to evaluate the association between timing of surgical debridement and outcomes such as infection and non-union in open tibial fractures. Materials and Methods: We performed a systematic review and meta-analysis of the literature to capture studies evaluating the association between timing of initial surgical debridement and infection or non-union, or other reported outcomes. We searched the MEDLINE, PubMed Central, EMBASE, SCOPUS, Cochrane Central and Web of Science electronic databases. Our methodology was guided by the Preferred Reporting Items for Systematic Reviews and Meta-Analyses statement and the Cochrane handbook for systematic reviews of interventions. Results: The systematic review included 20 studies with 10,032 open tibial fractures. The overall infection rate was 14.3% (314 out of 2193) and the overall non-union rate 14.2% (116 out of 817). We did not find any statistically significant association between delayed debridement and infection rate (OR = 0.87; 95% CI, 0.68 to 1.11; p = 0.23) or non-union rate (OR = 0.70; 95% CI, 0.42 to 1.15; p = 0.13). These findings did not change when we accounted for the effect of different time thresholds used for defining early and late debridement, nor with the Gustilo–Anderson classification or varying study characteristics. Conclusion: The findings of this meta-analysis support that delayed surgical debridement does not increase the infection or non-union rates in open tibial fracture injuries. Consequently, we propose that a reasonable delay in the initial debridement is acceptable to ensure that optimal management conditions are in place, such that the availability of surgical expertise, skilled staff and equipment are prioritised over getting to surgery rapidly. We recommend changing the standard guidance around timing for performing surgical debridement to ‘as soon as reasonably possible, once appropriate personnel and equipment are available; ideally within 24-h’.
