Gustilo IIIC fractures in the lower limb: our 15-year experience

Prevalence of chronic pain after severe lower limb injury (SLLI): A systematic review and meta-analysis

BACKGROUND

Globally, severe lower limb injuries (SLLIs) are the predominant cause of long-term injury related disability and poor functional outcomes. Chronic pain is a major source of this morbidity, but the magnitude of the contribution is not clearly understood. The aim of this systematic review and meta-analysis was to determine the prevalence of chronic pain following SLLIs in civilian and military patients.

METHOD

This systematic review was prospectively registered with The International Prospective Register of Systematic Reviews (PROSPERO) with study ID CRD42022313615. A systematic literature search (Medline, Embase, Ovid, and Web of Science) was performed to identify original studies that reported chronic pain outcomes for adults who underwent surgical treatment for SLLIs in a civilian or military setting. Risk of bias in included studies was assessed using the ROBINS-E tool, and quality assessment was reported at study level using the Newcastle-Ottawa Scale, and at outcome-level using the GRADE framework. Absolute (proportional) and relative (odds ratio) outcome measures were calculated and pooled using a random effects model.

RESULTS

Forty-three studies reporting the outcomes of 5601 patients were included. Estimated overall prevalence of pain was 63 % (CI 55-70 %). The prevalence of chronic pain in amputees (64 % (CI 55-73 %)) was similar to those who underwent limb salvage (56 % (CI 44-67 %)). The prevalence of chronic pain in civilian populations was 70 % (CI 63-77 %) compared to military populations (51 % (CI 35-66 %)). In amputees, the prevalence of residual limb pain was similar to phantom limb pain (OR 1.06 [0.64-1.78], p = 0.81, I2 = 92 %).

CONCLUSION

Most people who sustain a SLLI will suffer from chronic pain. Healthcare systems must continue to research interventions that can reduce the incidence and severity of long-term pain and ensure adequate resources are allocated for this common and debilitating complication.

A review of 10 patients treated with the masquelet technique and microsurgical technique combined for Gustilo type III open tibial fractures

BACKGROUND

Open tibial fractures often include severe bone loss and soft tissue defects and requires complex reconstructive operations. However, the optimal treatment is unclear.

METHODS

This retrospective study enrolled patients with Gustilo type III open tibial fractures from January 2018 to January 2021 to assess the clinical utility of Masquelet technique together with microsurgical technique as a combined strategy for the treatment of open tibial fractures. The demographics and clinical outcomes including bone union time, infection, nonunion and other complications were recorded for analysis. The bone recovery quality was evaluated by the AOFAS Ankle-Hindfoot Scale score and the Paley criteria.

RESULTS

We enrolled 10 patients, the mean age of the patients and length of bone defects were 31.7 years (range, 23-45 years) and 7.5 cm (range, 4.5-10 cm) respectively. Bone union was achieved for all patients, with an average healing time of 12.2 months (range, 11-16 months). Seven patients exhibited a bone healing time of less than 12 months, whereas 3 patients exhibited a bone healing time exceeding 12 months. No significant correlation was found between the length of bone loss and healing time. In addition, no deep infection or nonunion was observed, although 2 patients experienced wound fat liquefaction with exudates and 1 patient presented with a bloated skin flap. The average AOFAS Ankle-Hindfoot Scale score was 80.5 (range, 74-85), and all patients were evaluated as good or exellent based on the Paley criteria.

CONCLUSIONS

Our study indicated that the use of the Masquelet technique and the microsurgical technique as a combined strategy is safe and effective for the treatment of Gustilo type III open tibial fractures.

Physiotherapy assessment and treatment of patients with tibial external fixator: a systematic scoping review

PURPOSE

To map evidence regarding physiotherapy assessment and treatment of patients with tibial external fixator (EF), and to point out literature gaps for further research.

METHODS

Systematic scoping review conducted in four databases. We included both experimental and non-experimental studies involving patients with tibial EF and outcomes of interest. We recorded study design, population, sample size, sample age, reason for EF use, type of surgery, type of EF used, instruments used for assessing function, pain, quality of life, satisfaction, psychosocial aspects, and physiotherapy treatment descriptions from included studies. We categorised data accordingly to outcomes assessed and physiotherapy treatments description.

RESULTS

Eighty-six studies were included involving 3070 patients. Causes of fixator use were traumatic conditions, acquired and congenital deformities, and non-traumatic conditions, like compartmental osteoarthritis. Function was assessed in about three-quarters of included studies, though other outcomes were not presented in most studies. Only one study described satisfactorily the physiotherapy treatment. Almost half of the studies did not provide any description of the rehabilitation process.

CONCLUSIONS

There is little evidence about the assessment of function, pain, quality of life, satisfaction, psychosocial aspects, and other outcomes in tibial EF patients. Physiotherapy treatment in these patients is poorly reported.Protocol registration: Open Science Framework: doi:10.17605/OSF.IO/UT2DA.

Predicting Union, Osteomyelitis, and Amputation Outcomes of Gustilo IIIC Open Tibial Fractures: A Retrospective Study

OBJECTIVE

Open tibial fractures are frequently encountered in high-energy traumas and can result in significant complications such as nonunion, osteomyelitis, and even amputation. Among open tibial fractures, Gustilo type IIIC cases are particularly challenging due to the concomitant occurrence of neurovascular injuries and soft tissue defects. This study aimed to assess factors that affect union time and complications in Gustilo IIIC tibial fractures.

METHODS

Patients who presented at our center with IIIC open tibial fractures from January 2000 to October 2020 were eligible for this retrospective analysis. Patient demographics, fracture characteristics, and the timing, number, and type of surgical intervention were documented. Outcomes of interest included union time, occurrence of osteomyelitis, and amputation. We performed univariate analyses including chi-squared test, Fischer's exact test, analysis of variance, and Kruskal-Wallis test based on the normality of the data and multivariate analyses including Cox proportional hazards model and logistic regression analyses.

RESULTS

Fifty-eight patients were enrolled and grouped by fracture healing time; eight had timely union (13.8%); 27 had late union (46.6%); eight had delayed union (13.8%); three had nonunion (5.2%); and 12 underwent amputation (20.7%). Nine fractures (15.5%) were complicated by osteomyelitis. Union time was prolonged in cases of triple arterial injury, distal third fractures, multiple trauma with injury severity score (ISS) ≥ 16 points, and increased bone defect length. Additionally, a bone gap >50 mm, diabetes mellitus, low body mass index, and triple arterial injury in the lower leg were significant risk factors for amputation. A time from injury to definitive soft tissue coverage of more than 22 days was the major risk factor for osteomyelitis. A scoring system to predict union time was devised and the predicted probability of union within 2 years was stratified based on this score.

CONCLUSION

IIIC tibial fractures involving the distal third of the tibia, fractures with bone defects, triple arterial injury, and multiple trauma with ISS ≥16 points demonstrated delayed union, and an effective prediction system for union time was introduced in this study. Early soft tissue coverage can reduce the risk of osteomyelitis. Finally, diabetes and severe bone and soft tissue defects pose a higher risk of amputation.

Concomitant Orthopedic Injury is the Strongest Predictor of Amputation in Extremity Vascular Trauma

BACKGROUND

Although the risk of extremity amputation related to an isolated vascular injury is low, it increases significantly with concomitant orthopedic injury. Our study aims to evaluate and quantify the impact of risk factors associated with trauma-related extremity amputation in patients with vascular injury. We sought to determine whether there are other potential predictors of amputation.

METHODS

A retrospective review of patients with extremity vascular injury presenting to a single level 1 academic trauma center between January 1, 2007, and December 31, 2018, was performed. All patients diagnosed with major vascular injury to the upper or lower extremity were included. Data on patient demographics, medical comorbidities, anatomic location of vascular injury, and the presence of soft tissue or orthopedic injury were collected. The main outcome measure was major amputation of the affected extremity. Major amputation included below-the-knee amputation, above-the-knee amputation, as well as any amputation of the upper extremity at or proximal to the wrist.

RESULTS

We identified 250 extremities with major vascular injury in 234 patients. Of these, 216 (86.4%) were male and 34 (13.6%) female. The mean age was 32.2 years (range 18-79 years) and mean follow-up was 6.9 (standard deviation: 3.3) years. Just over half of injuries, 130 (52.0%) involved the lower extremity. Forty extremities (29 lower and 11 upper), or 16.0%, of total injured extremities, required major amputation during the follow-up period. Concomitant orthopedic injury was present in 106 of 250 (42%) injured extremities. Using univariable logistic regression models, variables with a significant association with major amputation included older age, higher body mass index, blunt mechanism of injury, concomitant orthopedic injury, soft tissue injury, and nerve injury, and the need for fasciotomy (P < 0.05). In multivariable analyses, blunt mechanism of injury (odds ratio [OR] (confidence ratio {CI}): 6.51 (2.29, 18.46), P < 0.001) and concomitant orthopedic injury (OR [CI]: 7.23 [2.22, 23.55], P = 0.001) remained significant predictors of amputation.

CONCLUSIONS

Concomitant orthopedic injury and blunt mechanism in the setting of vascular injury are associated with a higher likelihood of amputation in patients with extremity vascular injury. Further development of a vascular extremity injury protocol may be needed to enhance limb salvage. Findings may guide patient discussion regarding limb-salvage decision-making.

Predictive factors of amputation in infra-inguinal vascular trauma: a monocentric experience

OBJECTIVES

Infra-inguinal vascular injuries (IIVI) are emergencies involving both functional and vital prognosis. The choice between saving the limb or doing a first-line amputation is difficult even for an experienced surgeon. The aims of this work are to analyze early outcomes in our center and to identify predictive factors for amputation.

M METHODS

Between 2010 and 2017, we reviewed retrospectively patients with IIVI. The main criteria for judgement were: primary, secondary and overall amputation. Two groups of potential risk factors of amputation were analyzed: Those related to the patient: age, shock, ISS score; those related to the lesion: mechanism, above or below the knee, bone lesions, venous lesions and skin decay. A univariate and multivariate analysis were performed to determine the risk factor(s) independently associated with the occurrence of amputation.

RESULTS

57 IIVI were found in 54 patients. The mean ISS was 32,3 ± 21. A primary amputation was performed in 19%, and secondary in 14% of cases. Overall amputation rate was 35% (n=19). Multivariate analysis reveals that the ISS is the only predictor of primary (p=0.009; OR:1.07; CI:1.01-1.12) and global (p=0.04; OR:1.07; IC:1.02-1.13) amputation. A threshold value of 41 was selected as a primary amputation risk factor with a negative predictive value of 97%.

CONCLUSIONS

The ISS is a good predictor of the risk of amputation in IIVI. A threshold of 41 is an objective criterion helping to decide for a first-line amputation. Advanced age and hemodynamic instability should not be important in the decision tree.

How to measure success in lower extremity reconstruction, which outcome measurements do we use a systematic review and metanalysis

Different factors have to be considered and weighted in the treatment algorithm of lower extremity reconstruction. A combination of both clinicians' and patients' perspectives is necessary to provide a conclusive picture. Currently, there aren't any standardized and validated measurement data sets for lower extremity reconstructions. This makes it necessary to identify the relevant domains. We, therefore, performed a systematic review and metanalysis of outcome measurements and evaluated their ability to measure outcomes after lower extremity reconstruction. A systematic review and metanalysis according to the 'Preferred Reporting Items for Systematic Reviews and Meta-Analyses' protocol were performed for studies reporting at least one structured outcome measurement of lower extremity reconstruction. Both Patient (PROMs)- and Clinician reported outcome measurements (CROMs)were analyzed. Of the 2827 identified articles, 102 were included in the final analysis. In total 86 outcome measurements were identified, 34 CROMs, 44 PROMs and 8 (9.3%) outcome measurements that have elements of both. Twenty-four measure functional outcome, 3 pain, 10 sensations and proprioception, 9 quality of life, 8 satisfaction with the result, 5 measure the aesthetic outcome, 6 contours and flap stability and 21 contain multidomain elements. A multitude of different outcome measurements is currently used in lower extremity reconstruction So far, no consensus has been reached on what to measure and how. Validation and standardization of both PROMs and CROMs in plastic surgery is needed to improve the outcome of our patients, better meet their needs and expectations and eventually optimize extremity reconstruction by enabling a direct comparison of studies' results.

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.

Limb salvage results of Gustilo IIIC fractures of the lower extremity

This study aims to present our results for limb salvage in Gustilo IIIC open fractures of the femur and tibia. 92 patients with Gustilo IIIC fractures operated in our clinic between January 2000 and March 2016 were retrospectively evaluated. Demographic data, ischemia time, method of arterial repair, means of primary and secondary fixation, time to amputation, complications, and final VAS scores were recorded. The difference between the primary amputation rates of tibia and femur fractures was not statisti- cally significant (18% vs 21%, p>0.05). The difference between the secondary amputation rates of tibia and femur fractures was not significant (16% vs 27%, p>0.05). All secondary amputations were done within the first month during the initial hospital stay. Overall limb salvage rate was 69% for Gustilo IIIC fractures of the femur and 58% for Gustilo IIIC fractures of the tibia. The overall limb salvage rate was not significantly different between the two groups (p>0.05). At the final follow-up, patients in the limb salvage group had average VAS scores of 4.3 (femur) and 4.7 (tibia). The decision between amputation versus limb salvage remains a difficult decision that should be jointly made by the treating physicians and the patient.

Update in combined musculoskeletal and vascular injuries of the extremities

Combined musculoskeletal and vascular injuries of the extremities are conditions in which a multidisciplinary approach is a sine qua non to ensure life initially and limb viability secondarily. Vascular injuries as part of musculoskeletal trauma are usually the result of the release of a high energy load in the wound site so that the prognosis is determined by the degree of soft-tissue damage, duration of limb ischemia, patient’s medical status and presence of associated injuries. The management of these injuries is challenging and requires a specific algorithm of action, because they are usually characterized by increased morbidity, amputation rate, infection, neurological and functional deficits, and they could be life threatening. Although vascular injuries are rare and occur either isolated or in the context of major combined musculoskeletal trauma, the high index of suspicion, imaging control, and timely referral of the patient to organized trauma centers ensure the best functional outcome of the extremity in such challenging cases. Even after a successful initial treatment of a combined trauma pattern, long-term follow-up is crucial to prevent and detect early possible complications. The purpose of this manuscript is to provide an update on diagnosis and treatment of combined musculoskeletal and vascular injuries of the extremities, from an orthopedic point of view.

Roles of Trauma CT and CTA in Salvaging the Threatened or Mangled Extremity

Extremity arterial injuries account for up to 50% of all arterial traumas. The speed, accuracy, reproducibility, and close proximity of modern CT scanners to the trauma bay have led to the liberal use of CT angiography (CTA) when a limb is in ischemic jeopardy or is a potential source of life-threatening hemorrhage. The radiologist plays a critical role in the rapid communication of findings related to vessel transection and occlusion. Another role of CT that is often overlooked involves adding value to surgical planning. The following are some of the key questions addressed in this review: How does CTA help determine whether a limb is salvageable? How do concurrent multisystem injuries affect decision making? Which arterial injuries can be safely managed with observation alone? What damage control techniques are used to address compartment syndrome and hemorrhage? What options are available for definitive revascularization? Ideally, the radiologist should be familiar with the widely used Gustilo-Anderson open-fracture classification system, which was developed to prognosticate the likelihood of a functional limb salvage on the basis of soft-tissue and bone loss. When functional salvage is feasible or urgent hemorrhage control is required, communication with trauma surgeon colleagues is augmented by an understanding of the unique surgical, endovascular, and hybrid approaches available for each anatomic region of the upper and lower extremities. The radiologist should also be familiar with the common postoperative appearances of staged vascular, orthopedic, and plastic reconstructions for efficient clinically relevant reporting of potential down-range complications.

Tibial Shaft and Pilon Fractures With Associated Syndesmotic Injury: A Matched Cohort Assessment

OBJECTIVE

To determine the outcomes of pilon and tibial shaft fractures with syndesmotic injuries compared with similar fractures without syndesmotic injury.

DESIGN

Retrospective case-control study.

SETTING

Level 1 trauma center.

PATIENTS/PARTICIPANTS

All patients over a 5-year period (2012-2017) with tibial shaft or pilon fractures with a concomitant syndesmotic injury and a control group without a syndesmotic injury matched for age, OTA/AO fracture classification, and Gustilo-Anderson open fracture classification.

INTERVENTION

Preoperative or intraoperative diagnosis of syndesmotic injury with reduction and fixation of both fracture and syndesmosis.

MAIN OUTCOME MEASUREMENT

Rates of deep infection, nonunion, unplanned reoperation, and amputation in patients with a combined syndesmotic injury and tibial shaft or pilon fracture versus those without a syndesmotic injury.

RESULTS

A total of 30 patients, including 15 tibial shaft and 15 pilon fractures, were found to have associated syndesmotic injuries. The matched control group comprised 60 patients. The incidence of syndesmotic injury in all tibial shaft fractures was 2.3% and in all pilon fractures was 3.4%. The syndesmotic injury group had more neurologic injuries (23.3% vs. 8.3% P = 0.02), more vascular injuries not requiring repair (30% vs. 15%, P = 0.13), and a higher rate compartment syndrome (6.7% vs. 0%, P = 0.063). Segmental fibula fracture was significantly more common in patients with a syndesmotic injury (36.7% vs. 13.3%, P = 0.04). Fifty percent of the syndesmotic injury group underwent an unplanned reoperation with significantly more unplanned reoperations (50% vs. 27.5%, P = 0.04). The syndesmotic group had a significantly higher deep infection rate (26.7% vs. 8.3% P = 0.047) and higher rate of amputation (26.7% vs. 3.3% P = 0.002) while the nonunion rate was similar (17.4% vs. 16.7% P = 0.85).

CONCLUSIONS

Although syndesmotic injuries with tibial shaft or pilon fractures are rare, they are a marker of a potentially limb-threatening injury. Limbs with this combined injury are at increased risk of deep infection, unplanned reoperation, and amputation. The presence of a segmental fibula fracture should raise clinical suspicion to evaluate for syndesmotic injury.

LEVEL OF EVIDENCE

Large wounds reconstruction of the lower extremity with combined latissimus dorsi musculocutaneous flap and flow-through anterolateral thigh perforator flap transfer

BACKGROUND

Management of large wounds of the lower extremities remains a challenge for plastic and reconstructive surgeons. Herein, a surgical technique and clinical algorithm using the combined transfer of a latissimus dorsi (LD) musculocutaneous flap and flow-through anterolateral thigh (ALT) perforator flap for the treatment of extensive soft-tissue defects is described.

METHODS

From January 2012 to September 2018, 12 patients (six men and six women) aged 6-37 years, sustained injuries in road traffic accidents with large soft-tissue defects in the lower extremities. Seven cases were Gustillo Anderson type IIIB open fractures and two cases were Gustillo Anderson type IIIC open fractures. Two wounds were located in the knee joint, four in the calf, and six in the ankle and foot. The skin defect size ranged from 25 × 20 cm² to 36 × 25 cm² . All patients in this series underwent reconstruction using combined transfer of the LD musculocutaneous flap and flow-through ALT perforator flap, wherein the LD was attached through its pedicle to the distal continuation of the ALT flap.

RESULTS

The size of the flow-through ALT perforator flaps ranged from 13.5 × 6.5 cm² to 31 × 8.5 cm² . The size of the LD musculocutaneous skin paddle ranged from 25 × 6 cm² to 34 × 7 cm² , and that of the muscle paddle ranged from 13 × 3.5 cm² to 30 × 11 cm² . One patient experienced postoperative thrombosis of the venous pedicle, and the flap was salvaged after emergency re-exploration and thrombectomy. No other complications were observed postoperatively. The mean follow-up period was 26.8 months. All patients were able to ambulate independently at the end of the follow-up period.

CONCLUSIONS

The combined transfer of the LD musculocutaneous flap and flow-through ALT perforator flap ensured adequate surface coverage, making it a feasible procedure for large soft-tissue defects.

A Case of Reconstruction of a Type IIIc Open Tibial Fracture with Bone Loss and Warm Ischemia Time of 13 Hours: Quality of Life and Review of the Literature

BACKGROUND The management of open Gustilo IIIC fractures can be challenging even for experienced orthopedic surgeons. The decision between limb salvage and amputation is extremely difficult and the scoring systems do not seem to affect it significantly. Although ischemic time has been proven to be a major factor, attempts at reconstruction of limbs with ischemic time over 6 hours have been made in past decades. A simultaneous management of skeletal, soft-tissues, and vascular injury should be performed. This requires an orthoplastic surgeon who is capable of doing all the necessary operations by him/herself with hand-surgery and microsurgery expertise. CASE REPORT We present a case of a 49-year-old man with a type IIIC open tibial fracture with bone loss and warm ischemia time of 13 hours, who underwent revascularization and reconstruction with good radiological and functional results after a follow-up of 3 years. A few similar cases have been presented in the literature but none of them had a combination of bone loss, severe soft tissue injury, and complete vascular disruption after a crush injury. CONCLUSIONS The treatment of type IIIC open fractures of the tibia can be a demanding and time-consuming process. Detailed information about the necessity of multiple surgical interventions must be explained and fully understood by the patient in order to have realistic expectations.

Management of Gustilo Type IIIC Injuries in the Lower Extremity

Gustilo IIIC injuries of the lower extremity pose a significant challenge to the reconstructive surgeon. Key principles include early vascular repair and serial debridement followed by definitive coverage within 10 days. Primary reconstructive options following vascular repair include the anterolateral thigh flap or the latissimus dorsi muscle flap. Complications include elevated rates of microvascular thrombosis requiring return to the operating room, partial and complete flap loss, and infection. There is also an elevated rate of secondary amputation. However, in spite of higher complication rates, when approached thoughtfully and with an experienced multidisciplinary team, patients can achieve reasonable functional outcomes.

Orthopedic injuries in patients with multiple injuries: Results of the 11th trauma update international consensus conference Milan, December 11, 2017

BACKGROUND

In blunt trauma, orthopedic injuries are often associated with cerebral and torso injuries. The optimal timing for definitive care is a concern. The aim of the study was to develop evidence-based guidelines for damage-control orthopedic (DCO) and early total care (ETC) of pelvic and long-bone fractures, closed or open, and mangled extremities in adult trauma patients with and without associated injuries.

METHODS

The literature since 2000 to 2016 was systematically screened according to Preferred Reporting Items for Systematic Reviews and meta-analyses protocol. One hundred twenty-four articles were reviewed by a panel of experts to assign grade of recommendation and level of evidence using the Grading of recommendations Assessment, Development, and Evaluation system, and an International Consensus Conference, endorsed by several scientific societies was held.

RESULTS

The choice between DCO and ETC depends on the patient's physiology, as well as associated injuries. In hemodynamically unstable pelvic fracture patient, extraperitoneal pelvic packing, angioembolization, external fixation, C-clamp, and resuscitative endovascular balloon occlusion of the aorta are not mutually exclusive. Definitive reconstruction should be deferred until recovery of physiological stability. In long bone fractures, DCO is performed by external fixation, while ETC should be preferred in fully resuscitated patients because of better outcomes. In open fractures early debridement within 24 hours should be recommended and early closure of most grade I, II, IIIa performed. In mangled extremities, limb salvage should be considered for non-life-threatening injuries, mostly of upper limb.

CONCLUSION

Orthopedic priorities may be: to save a life: control hemorrhage by stabilizing the pelvis and femur fractures; to save a limb: treat soft tissue and vascular injuries associated with fractures, stabilize fractures, recognize, and prevent compartmental syndrome; to save functionality: treat dislocations, articular fractures, distal fractures. While DCO is the best initial treatment to reduce surgical load, ETC should be applied in stable or stabilized patients to accelerate the recovery of normal functions.

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.

Masquelet technique combined with microsurgical technique for treatment of Gustilo IIIC open distal tibial fractures: a retrospective single-center cohort study

Objective

This study was performed to investigate the clinical effects of the Masquelet technique combined with a microsurgical technique for treatment of Gustilo IIIC open distal tibial fractures.

Methods

Fifteen patients with a mean age of 39.3 ± 7.9 years (range, 21–43 years) with Gustilo IIIC open distal tibial fractures were treated by the Masquelet technique combined with a microsurgical technique from May 2013 to January 2017. The mean length of the bone defect was 6.9 ±2.2 cm (range, 5.2–10.7 cm). The mean area of the wound defect was 129.3 ± 41.4 cm² (range, 83.7–180 cm²). Complications and fracture healing were recorded. At the last follow-up, the functional outcome was measured using the Iowa ankle score.

Results

All 15 patients achieved bone healing, and the median healing time was about 6.1 months (range, 5–8 months). No complications such as infection or nonunion occurred. At the last follow-up, the median Iowa ankle score was 82 (range, 68–88). The rate of an excellent and good Iowa ankle score was 86.6%.

Conclusions

Application of the Masquelet technique combined with a microsurgical technique is an effective strategy for the treatment of Gustilo IIIC open distal tibial fractures.

A Multicentre Study: The Use of Micrografts in the Reconstruction of Full-Thickness Posttraumatic Skin Defects of the Limbs-A Whole Innovative Concept in Regenerative Surgery

The skin graft is a surgical technique commonly used in the reconstructive surgery of the limbs, in order to repair skin loss, as well as to repair the donor area of the flaps and cover the dermal substitutes after engraftment. The unavoidable side effect of this technique consists of unaesthetic scars. In order to achieve the healing of posttraumatic ulcers by means of tissue regeneration and to avoid excessive scarring, a new innovative technology based on the application of autologous micrografts, obtained by Rigenera technology, was reported. This technology was able to induce tissue repair by highly viable skin micrografts of 80 micron size achieved by a mechanical disaggregation method. The specific cell population of these micrografts includes progenitor cells, which in association with the fragment of the Extracellular Matrix (ECM) and growth factors derived by patients' own tissue initiate biological processes of regeneration enhancing the wound healing process. We have used this technique in 70 cases of traumatic wounds of the lower and upper limbs, characterized by extensive loss of skin substance and soft tissue. In all cases, we have applied the Rigenera protocol using skin micrografts, achieving in 69 cases the complete healing of wounds in a period between 35 and 84 days. For each patient, the reconstructive outcome was evaluated weekly to assess the efficacy of this technique and any arising complication. A visual analogue scale (VAS) was administered to assess the amount of pain felt after the micrografts' application, whereas we evaluated the scars according to the Vancouver scale and the wound prognosis according to Wound Bed Score. We have thus been able to demonstrate that Rigenera procedure is very effective in stimulating skin regeneration, while reducing the outcome scar.

Reconstruction of Gustilo Type IIIC Injuries of the Lower Extremity

BACKGROUND

Gustilo type IIIC open tibia fractures are characterized by an ischemic limb requiring immediate arterial repair. In this patient population, the decision between primary amputation and limb salvage can be challenging. This study aims to evaluate the reconstructive outcomes of patients with Gustilo type IIIC injuries.

METHODS

A single-center retrospective review of 806 lower extremity free flaps from 1976 to 2016 was performed. Flap loss and salvage rates for patients with Gustilo type IIIC injuries were determined. To determine the utility of performing salvage in this group, outcomes of the IIIC reconstructions were compared to those of similar patients with Gustilo I type IIB injuries with only a single patent vessel.

RESULTS

A total of 32 patients with Gustilo type IIIC injuries underwent reconstruction after traumatic injury. Ten patients (31.3 percent) experienced a perioperative complication, including seven unplanned returns to the operating room (21.9 percent), three partial flap losses (9.4 percent), and five complete flap losses (15.6 percent). When type IIIC injuries were compared with single-vessel Gustilo type IIIB injuries, no statistically significant differences were noted with respect to major perioperative complications (p = 0.527), unplanned return to the operating room (p = 0.06), partial flap loss (p = 0.209), complete flap loss (p = 0.596), or salvage rate (p = 0.368). Although this result was not statistically significant, Gustilo type IIIC injuries trended toward lower take-back rates and higher salvage rates compared with single-vessel Gustilo type IIIB injuries.

CONCLUSION

Patients with Gustilo type IIIC open tibia fractures should be considered candidates for limb salvage, as flap loss and reconstruction of these injuries are comparable to those of the routinely reconstructed single-vessel runoff type IIIB injuries.

Can Three Screws and a Fibula be a Viable Treatment for Managing Neglected Femoral Neck Fracture in Trans-Femoral Amputees? - A Report of Two Cases

Management of neglected femoral neck fracture in a trans-femoral amputee is difficult and challenging. There are limited options available for management of such a fracture. While arthroplasty (hemi or total) can be offered in older individuals, young patients should be offered an attempt of salvage of their native hips. Neglected femoral neck fracture in two young male patients who were trans-femoral amputees was managed by fixation through a Watson-Jones approach. Strategically placed Schanz screws and K-wires were used as joysticks for obtaining reduction and three 6.5mm cannulated screws were placed in a triangular fashion. An augmentation of the fixation was done with free fibula autograft placed in the center of the triangle. Union was achieved in both the cases. Patients were pain-free at the latest follow-up visit. Meticulous clinical and radiological evaluation is mandatory in multiply injured patients to avoid missing fractures. Fixation of neglected femoral neck fractures in young transfemoral amputees with three screws and a fibula can be considered a viable alternative to valgus osteotomy in cases where the stump is small for successful placement of the implant and where implant availability is an issue or the surgeon is comfortable in using screws and fibula for non-unions of femoral neck.

Prediction of tibial nonunion at the 6-week time point

INTRODUCTION

Intramedullary (IM) nail fixation is a common operative treatment, yet concerns regarding the frequency of complications, such as nonunion, remain. Treatment of tibial shaft fractures remains a challenge, and little evidence of prognostic factors that increase risk of nonunion is available. The aim of this study was to develop a predictive model of tibial shaft fracture nonunion 6 weeks after reamed intramedullary (IM) nail fixation based on commonly collected clinical variables and the radiographic union score for tibial fractures (RUST).

METHODS

A retrospective case-control study was conducted. All tibial shaft fractures treated at our level I trauma center from 2007 to 2014 were retrospectively reviewed. Only patients with follow-up until fracture healing or secondary operation for nonunion were included. Fracture gaps ≥3 mm were excluded. A total of 323 patients were included for study.

RESULTS

Infection within 6 weeks of operation, standard RUST, and the Nonunion Risk Determination (NURD) score had statistically significant associations with nonunion (odds ratio > or < 1.0; p < 0.01). The NURD score was increasingly predictive of nonunion with decreasing RUST. All patients in the high RUST group (RUST ≥ 10), achieved union regardless of NURD score. In the medium RUST group (RUST 6-9), 25% of patients with a NURD score ≥7 experienced nonunion. In the low RUST group (RUST <6 or infection within 6 weeks), 69% of patients with a NURD score ≥7 experienced nonunion.

CONCLUSION

Three variables predicted nonunion. Based on these variables, we created a clinical prediction tool of nonunion that could aid in clinical decision making and discussing prognosis with patients.

Treatment of tibial nonunion with bone defect using a heterotopic ossification as autologous bone graft: literature overview and case report

INTRODUCTION

Nonunion after open fracture of the lower leg is a frequent complication with a prevalence of up to 40%. In cases with major bone defects, revision of the osteosynthesis with bone grafting is commonly performed. Until today, there is no report on treatment of a tibial nonunion with transplantation of a heterotopic ossification.

PRESENTATION OF CASE

We present a case of a 27-year-old male patient, who suffered from a paragliding accident with major injuries. An open fracture of the lower leg (Gustilo-Anderson IIIB) was initially treated with external fixation and vacuum-assisted closure, followed by reamed intramedullary nailing. The tibia resulted in a bone defect situation with nonunion. It was successfully treated with revision, fibular osteotomy and transplantation of a heterotopic ossification, harvested from the ipsilateral hip.

CONCLUSION

In special cases, autologous transplantation of a mature heterotopic ossification is an attractive bone graft option in treating nonunion defects.

Open Fractures of the Hand: Review of Pathogenesis and Introduction of a New Classification System

Open fractures of the hand are a common and varied group of injuries. Although at increased risk for infection, open fractures of the hand are more resistant to infection than other open fractures. Numerous unique factors in the hand may play a role in the altered risk of postinjury infection. Current systems for the classification of open fractures fail to address the unique qualities of the hand. This article proposes a novel classification system for open fractures of the hand, taking into account the factors unique to the hand that affect its risk for developing infection after an open fracture.

Gustilo IIIB Open Tibial Fractures: An Analysis of Infection and Nonunion Rates

BACKGROUND

Gustilo IIIB tibial fractures are associated with high rates of infection and nonunion. This study evaluates the impact of factors such as patient demographics, mechanism of injury, time to the first debridement, and time to flap coverage on the union and infection rates.

MATERIALS AND METHODS

A retrospective analysis was performed on all patients with open tibial fractures who presented to our tertiary trauma center over 13 years from April 2000 to August 2013. All patients were followed for at least 6 months and continued till radiographic evidence of union (maximum 72 months). Time to fracture union was based on radiological evidence of callus bridging at least three cortices. Information on infection rates and the presence of microbes were evaluated.

RESULTS

A total of 120 patients were analyzed. The mean time to fracture union was 33.8 weeks. Younger age was associated with a lower risk of nonunion with the mean age being 30.4 years in union group compared to 38.2 in the delayed-union group. Smoking was associated with an increased risk of delayed union with revision surgery being needed in 61.5% of smokers compared to 36.4% in nonsmokers. Rates of infection were high at 30.3%. Smoking was associated with an increased risk of infection (65.4% vs. 24.7%).

CONCLUSION

High-energy open tibia fractures required an average of 8.5 months to heal and delayed or nonunion at an earlier juncture cannot be assumed.

Is amputation a viable treatment option in lower extremity trauma?

INTRODUCTION

There is currently no consensus on how to treat patients with lower extremity trauma. Should amputation be performed early on to avoid complications or should the limb be saved at any price? The goal of this study was to show that early amputation is a viable treatment option in lower extremity trauma cases.

MATERIAL AND METHODS

Twenty patients who underwent early amputation and 16 patients who underwent limb-salvage were included with a minimum follow-up of 1year. The main endpoints were the Mangled Extremity Severity Score (MESS) used to predict amputation, complications, sequelae, bone union and functional outcomes.

RESULTS

The amputees had a higher MESS score than those treated conservatively (7.8 vs. 4.9, P<0.00001), had a shorter hospital stay (P<0.022) and had fewer postoperative complications (P<0.003), especially infection-related (P<0.001). The prevalence of infection in limb-salvage patients was 61%. There was no significant difference between the two groups in terms of quality of life.

DISCUSSION

In cases of lower extremity trauma, early amputation and limb-sparing treatment each have their advantages and disadvantages. Early amputation seems to be better in cases of complications, despite similar quality of life in the two groups in the long-term. It is a viable treatment option in cases of lower extremity trauma. Amputation must not be considered as a failure, but a deliberate choice due to the functional impact of complications that occur after limb-salvage.

Management of Gustilo Anderson III B open tibial fractures by primary fascio-septo-cutaneous local flap and primary fixation: The 'fix and shift' technique

BACKGROUND

Open fractures of tibia have posed great difficulty in managing both the soft tissue and the skeletal components of the injured limb. Gustilo Anderson III B open tibial fractures are more difficult to manage than I, II, and III A fractures. Stable skeletal fixation with immediate soft tissue cover has been the key to the successful outcome in treating open tibial fractures, in particular, Gustilo Anderson III B types. If the length of the open wound is larger and if the exposed surface of tibial fracture and tibial shaft is greater, then the management becomes still more difficult.

MATERIALS AND METHODS

Thirty six Gustilo Anderson III B open tibial fractures managed between June 2002 and December 2013 with "fix and shift" technique were retrospectively reviewed. All the 36 patients managed by this technique had open wounds measuring >5 cm (post debridement). Under fix and shift technique, stable fixation involved primary external fixator application or primary intramedullary nailing of the tibial fracture and immediate soft tissue cover involved septocutaneous shift, i.e., shifting of fasciocutaneous segments based on septocutaneous perforators.

RESULTS

Primary fracture union rate was 50% and reoperation rate (bone stimulating procedures) was 50%. Overall fracture union rate was 100%. The rate of malunion was 14% and deep infection was 16%. Failure of septocutaneous shift was 2.7%. There was no incidence of amputation.

CONCLUSION

Management of Gustilo Anderson III B open tibial fractures with "fix and shift" technique has resulted in better outcome in terms of skeletal factors (primary fracture union, overall union, and time for union and malunion) and soft tissue factors (wound healing, flap failure, access to secondary procedures, and esthetic appearance) when compared to standard methods adopted earlier. Hence, "fix and shift" could be recommended as one of the treatment modalities for open III B tibial fractures.

Will My Tibial Fracture Heal? Predicting Nonunion at the Time of Definitive Fixation Based on Commonly Available Variables

BACKGROUND

Accurate prediction of tibial nonunions has eluded researchers. Reliably predicting tibial nonunions at the time of fixation could change management strategies and stimulate further research.

QUESTIONS/PURPOSES

We asked (1) whether data from medical records, fracture characteristics, and radiographs obtained at the time of fixation would identify features predictive of tibial fracture nonunion; and (2) whether this information could be used to create a model to assess the chance of nonunion at the time of intramedullary (IM) nail fixation of the tibia.

METHODS

We retrospectively reviewed all tibial shaft fractures treated at our center from 2007 to 2014. We conducted a literature review and collected data on 35 factors theorized to contribute to delayed bone healing. Patients were followed to fracture healing or surgery for nonunion. Patients with planned prophylactic nonunion surgery were excluded because their nonunions were anticipated and our focus was on unanticipated nonunions. Our cohort consisted of 382 patients treated with IM nails for tibial shaft fractures (nonunion, 56; healed, 326). Bivariate and multivariate regression techniques and stepwise modeling approaches examined the relationship between variables available at definitive fixation. Factors were included in our model if they were identified as having a modest to large effect size (odds ratio > 2) at the p < 0.05 level.

RESULTS

A multiple variable logistic regression model was developed, including seven factors (p < 0.05; odds ratio > 2.0). With these factors, we created the Nonunion Risk Determination (NURD) score. The NURD score assigns 5 points for flaps, 4 points for compartment syndrome, 3 points for chronic condition(s), 2 points for open fractures, 1 point for male gender, and 1 point per grade of American Society of Anesthesiologists Physical Status and percent cortical contact. One point each is subtracted for spiral fractures and for low-energy injuries, which were found to be predictive of union. A NURD score of 0 to 5 had a 2% chance of nonunion; 6 to 8, 22%; 9 to 11, 42%; and > 12, 61%.

CONCLUSIONS

The proposed nonunion prediction model (NURDS) seems to have potential to allow clinicians to better determine which patients have a higher risk of nonunion. Future work should be directed at prospectively validating and enhancing this model.

Factors affecting clinical outcomes after treatment of extra-articular open tibial fractures

BACKGROUND

Tibial fractures are the most common long bone fracture and are often associated with severe soft tissue and bone defects. The objectives of our study were to describe the management and clinical results of patients with extra-articular open tibial fractures and to identify factors associated with a poor functional outcome.

METHODS

This study included 82 adults available for follow-up for over 1 year after surgery. According to the AO Foundation/Orthopedic Trauma Association fracture classification, 26 fractures were type 41 A, 34 were type 42, and 22 were type 43 A. In accordance with the Gustilo-Anderson classification system, 31 were type I, 19 were type II, and 32 were type III. Initial nerve injury was confirmed in 18 cases.

RESULTS

Definitive fixation occurred at a mean of 6.73 days (range, 0-16 days) after the injury. Soft tissue reconstruction was as follows: primary closure with debridement, 50 patients; split-thickness skin graft, 5; perforator based rotational flaps, 10; and free flaps, 17. Complications occurred in 29 cases (35.4%): superficial infection, 5 patients; deep infection, 3; primary suture site skin necrosis, 7; partial flap necrosis, 4; malalignment, 7; joint stiffness, 2; and hardware breakage, 1. Thirty additional operations (36.6%) were performed during the hospital stay. Mean bone union time was 20.4 weeks (range, 13-63 weeks) and the mean Lower Extremity Functional Scale score (LEFS) was 70.93 (range, 36-79). Multiple linear regression analysis indicated that skin defect size (p = 0.002), and occurrence of complications (p < 0.001) correlated with the LEFS score.

CONCLUSION

Functional outcome after treatment of extra-articular open tibial fractures was influenced by the skin defect size and the presence of any complications. This suggests that good clinical results can be expected if complications are prevented through proper reduction, firm fixation, early soft tissue reconstruction, and early rehabilitation.

Total and subtotal amputation of lower limbs treated by acute shortening, revascularization and early limb lengthening with ilizarov ring fixation - a retrospective study

We present the results of 15 patients who sustained total or subtotal traumatic amputation of the lower limbs who were treated by acute limb shortening and stabilisation with external fixator, revascularization and early lengthening with Ilizarov ring fixator. The mean age of the patients was 28 years [5-38]. There were three females and 12 males. The mean Mangled Extremity Severity Score was 8.5 [range 6-11]. The mean amount of shortening done was 6.9cm [range 3-12.5] to enable revascularization and soft tissue repair. Three cases had to be amputated early because of failure of vascular repair. In the remaining 12 patients who were followed up the mean interval between revascularization and application of Ilizarov ring fixator was 4.7 weeks [range 3-10]. The mean follow up was 6.5 years [3-16 years]. Union occurred in all patients. Ten of the 12 patients returned to work and residual shortening was present in two cases. We conclude that whenever possible lower limb salvage should be undertaken.

Management of the Floating Knee in Polytrauma Patients

Ipsilateral fracture of the femur and tibia, or floating knee, is a rare injury that is found almost exclusively in polytrauma or high-energy trauma patients. It presents a combination of diaphyseal, metaphyseal and intra-articular fractures of the femur and tibia, with a high incidence of neurovascular, ligamentous and soft-tissue injuries. The functional outcome and, in some cases, the life, of such polytrauma patients depends largely on a correct therapeutic approach being taken. In general, the treatment decided upon will depend on the individual characteristics present, regarding aspects such as the patient’s general condition, the fracture line and the state of the soft tissues. The treatment provided may be the same as when single fractures are presented, but it is often necessary to consider whether certain techniques or surgical approaches may interfere with other lines of treatment. It is essential at all times to take into consideration the associated injuries and complications before deciding upon a treatment strategy. Ligamentous injuries play an important role in these injuries, much more so than when fractures occur singly. Therefore, these injuries require management by an experienced multidisciplinary team.

The use of secure anonymised data linkage to determine changes in healthcare utilisation following severe open tibial fractures

Severe open fractures of the lower limbs are complex injuries requiring expert multidisciplinary management in appropriate orthoplastic centres. This study aimed to assess the impact of open fractures on healthcare utilisation and test the null hypotheses that there is no difference in healthcare utilisation between the year before and year after injury, and that there is no difference in healthcare utilisation in the year post-injury between patients admitted directly to an orthoplastic centre in keeping with the joint BOA/BAPRAS standards and those having initial surgery elsewhere. This retrospective cohort study utilising secure anonymised information linkage (SAIL), a novel databank of anonymised nationally pooled health records, recruited patients over 18 years of age sustaining severe open lower limb fractures managed primarily or secondarily at our centre and who had data available in the SAIL databank. 101 patients met inclusion criteria and 90 of these had records in the SAIL databank. The number of days in hospital, number of primary care attendances, number of outpatient attendances and number of emergency department attendances in the years prior and subsequent to injury were recorded. Patients sustaining open fractures had significantly different healthcare utilisation in the year after injury when compared with the year before, in terms of days spent in hospital (23.42 vs. 1.70, p=0.000), outpatient attendances (11.98 vs. 1.05, p=0.000), primary care attendances (29.48 vs. 11.99, p=0.000) and emergency department presentations (0.2 vs. 0.01, p=0.025). Patients admitted directly to orthoplastic centres had significantly fewer operations (1.78 vs. 3.31) and GP attendances (23.6 vs. 33.52) than those transferred in subsequent to initial management in other units. There is a significant increase in healthcare utilisation after open tibial fracture. Adherence to national standards minimises the impact of this on both patients and health services.

Meta-analysis of prognostic factors for amputation following surgical repair of lower extremity vascular trauma

Background

Lower extremity vascular trauma (LEVT) is a major cause of amputation. A clear understanding of prognostic factors for amputation is important to inform surgical decision-making, patient counselling and risk stratification. The aim was to develop an understanding of prognostic factors for amputation following surgical repair of LEVT.

Methods

A systematic review was conducted to identify potential prognostic factors. Bayesian meta-analysis was used to calculate an absolute (pooled proportion) and relative (pooled odds ratio, OR) measure of the amputation risk for each factor.

Results

Forty-five studies, totalling 3187 discrete LEVT repairs, were included. The overall amputation rate was 10·0 (95 per cent credible interval 7·4 to 13·1) per cent. Significant prognostic factors for secondary amputation included: associated major soft tissue injury (26 versus 8 per cent for no soft tissue injury; OR 5·80), compartment syndrome (28 versus 6 per cent; OR 5·11), multiple arterial injuries (18 versus 9 per cent; OR 4·85), duration of ischaemia exceeding 6 h (24 versus 5 per cent; OR 4·40), associated fracture (14 versus 2 per cent; OR 4·30), mechanism of injury (blast 19 per cent, blunt 16 per cent, penetrating 5 per cent), anatomical site of injury (iliac 18 per cent, popliteal 14 per cent, tibial 10 per cent, femoral 4 per cent), age over 55 years (16 versus 9 per cent; OR 3·03) and sex (men 7 per cent versus women 8 per cent; OR 0·64). Shock and nerve or venous injuries were not significant prognostic factors for secondary amputation.

Conclusion

A significant proportion of patients who undergo lower extremity vascular trauma repair will require secondary amputation. This meta-analysis describes significant prognostic factors needed to inform surgical judgement, risk assessment and patient counselling.

Early versus late flap coverage for open tibial fractures

PURPOSE

To compare early versus late flap coverage for open tibial fractures.

METHODS

Medical records of 83 men and 6 women (mean age, 38 years) who underwent fixation for open tibial fractures (Gustilo grades IIIB and IIIC) followed by flap coverage within (n=30) or after (n=59) 72 hours were reviewed. All fractures were treated within 24 hours. Outcome measures included bone union, infection, flap failure, the need for secondary procedures to achieve union, and eventual amputation. The early and late flap coverage groups were compared.

RESULTS

Early flap coverage was associated with shorter length of hospitalisation (31.4 vs. 55.8 days, p<0.01), lower deep infection rates (23% vs. 54%, p<0.01), and smaller number of surgical procedures (6.4 vs. 9.2, p=0.01). The 2 groups did not differ significantly in terms of the time to bone union, flap failure, amputation, and the need of secondary procedures to facilitate bone union.

CONCLUSION

In severe open tibial fractures, early soft-tissue coverage (within 72 hours) was associated with more favourable outcomes in terms of length of hospitalisation and infection.
