The functional outcome of severe, open tibial fractures managed with early fixation and flap coverage

Staged wound closure using tension-reducing taping technique with negative pressure wound therapy in lower extremity open fractures: A retrospective review

BACKGROUND

In the treatment of lower extremity open fractures Gustilo-Anderson classification types IIIA/IIIB borderline cases, closing open wound under strong tension may lead to wound edge necrosis and the need for soft tissue reconstruction. The purpose of this study is to examine whether staged wound closure using tension-reducing taping with negative pressure wound therapy (NPWT) could prevent wound edge necrosis in borderline type lower extremity open fractures.

MATERIALS AND METHODS

Patients with ⅢA/ⅢB borderline type lower extremity open fractures who were treated at our institution were included. The patients were divided into two groups: those who underwent conventional wound closure (Group 1) and those who underwent staged closure using tension-reducing taping (Group 2). Characteristics of patients and their injuries were compared between the two groups. In addition, the presence or absence of wound edge necrosis after wound closure, soft tissue reconstruction, and wound infection were compared between the two groups.

RESULTS

Twenty-six patients were included in Group 1 and 21 patients were included in Group 2. There were no significant differences in characteristics of patients and their injuries between the two groups. The rate of wound edge necrosis and the need for local flaps were significantly higher in Group 1 (p = 0.002, 0.027). There was no significant difference in infection rates between the two groups (p = 0.495).

CONCLUSION

For ⅢA/ⅢB borderline type lower extremity open fractures, staged wound closure using tension-reducing taping technique with NPWT can reduce wound edge necrosis and prevent the transition to iatrogenic type ⅢB.

The trans-flap approach in secondary surgeries for severe open limb fractures

INTRODUCTION

The standard treatment for severe open limb fractures comprises fracture fixation and flap surgery. In complicated injuries, secondary surgeries are required for flap-covered fracture sites. Given the risk of flap necrosis, secondary surgery using a flap-dividing approach is generally avoided. Nonetheless, a more efficient secondary surgery can be undertaken in combination with strategies to prevent flap necrosis. We describe a "trans-flap approach" for secondary surgery and the subsequent treatment course and clinical outcomes of patients who were treated with this novel approach.

METHODS

We retrospectively identified and enrolled patients who underwent flap surgery for severe open limb fractures and subsequently received secondary surgery using the trans-flap approach between 2020 and 2023. Patient demographics and injuries, type of flap used for acute soft tissue reconstruction, indications for secondary surgery, duration from soft tissue reconstruction to secondary surgery, soft tissue healing, and postoperative complications were investigated.

RESULTS

Among the 15 study participants, the injuries involved the hand in 3 cases, lower leg in 9 cases, and foot in 3 cases. The flaps used for acute soft tissue reconstruction included a pedicled flap in 2 cases and a free flap in 13 cases. In all cases, the wounds healed without necrosis and complications, except for a deep infection in 1 patient.

CONCLUSION

Regardless of the type of flap, wound healing was achieved without necrosis in all 15 cases. Trans-flap approach can be an effective option in secondary surgery for severe open limb fractures.

The Continued Impact of Godina's Principles: Outcomes of Flap Coverage as a Function of Time After Definitive Fixation of Open Lower Extremity Fractures

BACKGROUND

 Early soft tissue coverage of open lower extremity fractures within 72 hours of injury leads to improved outcomes. Little is known about outcomes when definitive fixation is completed first. The purpose of this study is to quantify postoperative outcomes when soft tissue reconstruction is delayed until after definitive open reduction and internal fixation (ORIF) is completed.

METHODS

 An insurance claims database was queried for all patients with open lower extremity fractures between 2010 and 2020 who underwent free or axial flap reconstruction after ORIF. This cohort was stratified into three groups: reconstruction performed 0 to 3, 3 to 7, and 7+ days after ORIF. The primary outcome was 90-day complication and reoperation rates. Bivariate and multivariable regression of all-cause complications and reoperations was evaluated for time to flap as a risk factor.

RESULTS

 A total of 863 patients with open lower extremity fractures underwent ORIF prior to flap soft tissue reconstruction. In total, 145 (16.8%), 162 (18.8%), and 556 (64.4%) patients underwent soft tissue reconstruction 0 to 3 days, 4 to 7 days, and 7+ days after ORIF, respectively. The 90-day complication rate of surgical site infections ( SSI; 16.6%, 16,7%, 28.8%; p = 0.001) and acute osteomyelitis (5.5%, 6.2%, 27.7%; p < 0.001) increased with delayed soft tissue reconstruction. Irrigation and debridement rates were directly related to time from ORIF to flap (33.8%, 51.9%, 61.9%; p < 0.001). Hardware removal rates were significantly higher with delayed treatment (10.3%, 9.3%, 39.3%; p < 0.001). The 0 to 3 day (odds ratio [OR] = 0.22; 95% confidence interval [CI]: 0.15, 0.32) and 4 to 7 day (OR = 0.26; 95% CI: 0.17, 0.40) groups showed protective factors against all-cause complications after bivariate and multivariate regression.

CONCLUSION

 Early soft tissue reconstruction of open lower extremity fractures performed within 7 days of ORIF reduces complication rates and reduces the variability of complication rates including SSIs, acute osteomyelitis, and hardware failure.

Delayed Reconstruction of the Perforator Pedicle Propeller Flap after the Induced Membrane Technique for Gustilo IIIB Open Distal Tibial Fracture

This study aimed to evaluate the safety and efficacy of delayed reconstruction of the perforator pedicle propeller flap after the induced membrane technique in the treatment of Gustilo IIIB open distal tibial fracture, and to evaluate the clinical outcome and complications of two different perforator pedicle propeller flaps.Thirty-four patients with Gustilo IIIB open distal tibial fractures treated by the induced membrane technique and delayed reconstruction of two different perforator pedicle propeller flaps from May 2017 to March 2022 were retrospectively analyzed. Patients were divided into two groups according to the different kinds of perforator pedicle propeller flaps covered. The operation required two stages. The Radiographic Union Score for Tibial fractures (RUST) was used to evaluate the healing of the tibial bone defect. The American Orthopaedic Foot and Ankle Society (AOFAS) score was used to evaluate ankle function. The complications associated with the technique were recorded.The number of serial debridements, excluding those performed during emergency and final operations, was a mean of 2.28 ± 0.83 in the PAPF group. The PAPF group had a mean bone defect length of 6.76 ± 0.69 cm, the median healing time of 13.11 ± 0.96 months, RUST score 12.68 ± 1.63, and AOFAS score of 84.12 ± 6.38. On the other hand the PTAPF group's mean bone defect length was 6.73 ± 0.95 cm, the median healing time 12.63 ± 1.46 months, RUST score 13.73 ± 1.53 and AOFAS score 82.79 ± 5.49. There were no observed significant differences the two groups in the number of serial debridements, bone defect length, bone union time, RUST score, or AOFAS score (p > 0.05). Flap size ranged from 9 × 6 cm2 to 14 × 7 cm2 in the PAPF group and from 9 × 6 cm2 to 13 × 7 cm2 in the PTAPF group. There were no severe complications such as flap-related complications or amputation. The differences in complications in the two groups were not statistically significant.In cases of severe open tibial fracture, the reconstructive method is important. When delayed reconstruction is inevitable, surgeons should first perform radical debridement, followed by vacuum sealing drainage as a bridging therapy; both PAPF and PTAPF can be considered for definitive soft tissue coverage.

Simultaneous internal fixation and latissimus dorsi pedicle flap coverage: A reliable regimen for open fractures with accompanying sizable soft tissue loss of the upper extremities

BACKGROUND

The optimal treatment protocol for open fractures with accompanying sizable soft tissue defect of the upper extremities has not been specifically delineated. The authors described the concurrent use of internal fixation and latissimus dorsi (LD) pedicle flap coverage in managing such complex fractures.

METHODS

Twenty patients with open fractures accompanied by large soft tissue defect of the upper extremities (8 clavicle fractures and 12 humeral fractures) were treated by fix & LD pedicle flap. The dimension of the defect, time to fix & flap, post-operative complications, time to union and clinical measurements were recorded.

RESULTS

The mean size of the defect was 132.45 cm2 (range 6-12 x 2-20 cm2). The average time to fix & flap was 9.9 days (range 7-14). Fractures union was achieved in all patients with an average duration of 18.5 weeks (range 14-28). Regarding post-operative complications, distal flap necrosis occurred in 3 patients, retained seroma in 3 and heterotopic ossification in 1. By the Mayo Elbow Performance (MEP) score, 3 cases were considered to be excellent, 6 were good, 7 were fair and 4 were poor. By the University of California-Los Angeles (UCLA) shoulder score, 2 cases were considered to be excellent, 7 were good, 7 were fair and 4 were poor. The average Disabilities of Arm, Shoulder and Hand (DASH) score was 31.29 (range 12.5-58.3).

CONCLUSION

Fix & LD pedicle flap is a reliable regimen for open fractures with sizable soft tissue defect of the clavicle and humerus.

Concurrent plate fixation and pedicled flap coverage for open fractures complicated by soft tissue loss of the tibia in pediatric cohort: a clinical series

BACKGROUND

The optimal treatment of open fractures complicated by soft tissue loss of pediatric tibial fractures remains inconclusive. The author described a protocol of concurrent plate fixation and pedicled flap coverage and retrospectively reviewed the outcomes of such injuries.

METHODS

A total of 25 pediatric cases with Gustilo lllB open tibial fracture were treated by single-stage plate fixation and pedicled flap reconstruction. The reviewed information consisted of time to fix and flap, type of plate, type of pedicled flap, fracture union time, postoperative complication and the clinical outcomes by objective scoring system.

RESULTS

Fix and flap was undergone between 7 and 12 days after injury with the average time of 8.2 days. Regarding the type of plate, narrow LCP was applied in 8, 3.5 mm precontoured LCP in 10, 5.0 mm precontoured in 2 and double LCP in 5. According to soft tissue reconstruction, the medial gastrocnemius flap was selected in 6 cases, myocutaneous medial gastrocnemius flap in 2, soleus flap in 3, hemisoleus flap in 5, reverse sural flap in 6 and combined medial gastrocnemius and hemisoleus flaps in 3. No flap-related complication was demonstrated. All cases established fracture union in between 12 and 24 weeks with an average time to union of 17.7 weeks. According to postoperative complications, infected plate occurred in 2 cases and implant irritation in 5. According to Puno functional score, excellent results were presented in 7 cases and good results in 18 cases.

CONCLUSION

Single-stage plate fixation and pedicled flap coverage are a reliable regimen for pediatric open fractures complicated by soft tissue loss of the tibia.

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.

Ankle impingement after extra-articular open fracture of the leg: Full arthroscopic treatment in the supine position

OBJECTIVE

Extra-articular open fractures of the leg often result from high energy trauma. After healing, a painful ankle impingement may occur. In the event of anterior and posterior impingements, arthroscopic treatment may require two surgical positions. We propose an operative strategy to treat anterior and posterior ankle impingement after extra-articular open fracture of the leg. Our hypothesis is that this strategy is simple, effective and with a low risk of complication.

MATERIAL AND METHOD

Anterior ankle impingements were treated by anterior arthroscopy in supine position; anterior and posterior impingements were treated by anterior and posterior arthroscopy in supine position; anterior and posterior impingements associated with retraction of gastrocnemius muscles were treated with anterior arthroscopy in supine position followed by posterior arthroscopy in prone position, and an open tendon lengthening of the calcaneal tendon in the same position. The anterior and posterior arthroscopic release was tested in the cadaver laboratory. Then, the surgical strategy was applied to our patients in our clinical practice. After, we analysed retrospectively the results of the strategy in the first patients treated for a painful ankle impingement after extra-articular open fracture of the leg. The data retrieved were the importance of pain (VAS), the presence of clinical instability, ankle mobility, gastrocnemius retraction and the AOFAS functional score and the post-operative complications. Then, these data were compared before the surgery and at last follow-up.

RESULTS

From the cadaver laboratory, anterior and posterior arthroscopic release was possible in all cases without changing position. From our clinical practice, we included 5 patients (3 women and 2 men, mean age 43 years) suffering from an ankle impingement after extra-articular open fracture of the leg (2 patients with isolated anterior impingement, 1 patient with anterior and posterior impingement, and 2 patients with anterior and posterior impingement plus a gastrocnemius retraction). All post-operative parameters (pain, range of motion and AOFAS score) at mean follow-up of 53 months were improved. No post-operative complication was reported.

CONCLUSION

We propose a surgical strategy adapted to the different clinical presentations of ankle impingement after extra-articular open fracture of the leg.

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

OBJECTIVES

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

DESIGN

International multicenter, retrospective comparative cohort study.

PATIENTS/PARTICIPANTS

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

METHODS

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

MAIN OUTCOME MEASUREMENT

Deep infection after definitive fixation and flap coverage.

RESULTS

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

CONCLUSION

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

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

BACKGROUND

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

METHODS

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

RESULTS

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

CONCLUSIONS

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

Patient-reported outcomes following free flap lower extremity reconstruction: A systematic review and meta-analysis

PURPOSE

Free flap reconstruction in the lower extremity has shown success for the management of large and complex defects, restoration of function, and favorable aesthetic outcomes. Patient-reported outcomes (PROs) have not been well explored in previous literature. This meta-analysis aimed to provide a comprehensive summary of PROs after free flap reconstruction in the lower extremity.

METHODS

We searched MEDLINE and Embase from 1946 to 2021 for studies reporting on PROs following free flap reconstruction in the lower extremity.

RESULTS

Overall, 53 studies were included, and 11 studies reported validated PRO measures for meta-analysis. A total of 1953 patients underwent reconstruction with 1958 free flaps for lower limb defects with a mean follow-up of 3.26 (0.25-7.83) months. The mean postoperative Lower Extremity Functional Scale (LEFS) scores were 60.3 (±12) out of 80 points (4 studies, 85 patients). The mean postoperative AOFAS scores were 75.1 (±15) out of 100 points (4 studies, 68 patients). The mean postoperative SF-36 scores were 88.1 (±8.0) out of 100 points; mental health component was 48.7 (±8.9), and physical component was 38.4 (±8.2), out of 50 points (4 studies, 88 patients).

CONCLUSION

Our findings demonstrated that patients report improved physical health, mental health, and function following lower extremity reconstruction with free flaps. Patients reported similar improvements in functional scores following lower extremity reconstruction regardless of their free flap type. Furthermore, patients with myocutaneous flaps may have improved mental health and worse physical health scores when compared to perforator flaps. The evidence profiles presented in this review indicate that additional research is needed to help guide future decision-making.

Current Perspectives on the Management of Bone Fragments in Open Tibial Fractures: New Developments and Future Directions

Open tibial fractures may be associated with bone loss at the time of the injury or following surgical debridement of the fracture. This article discusses the various treatment options available and the latest developments surrounding the management of free bone fragments in open tibial fractures.

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

OBJECTIVE

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

DESIGN

Consecutive cohort study.

PATIENTS/PARTICIPANTS

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

INTERVENTION

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

MAIN OUTCOME MEASUREMENTS

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

RESULTS

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

CONCLUSIONS

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

SOFT TISSUE RECONSTRUCTION IN SEVERE OPEN LEG FRACTURE

Methodology Eighteen patients who sustained severe open leg fractures (Gustilo’s III) were treated, average age of 25years. Aims of study:The project is to evaluate: the benet of early over late soft tissue reconstruction in severe open leg fractures (Gustilo type III) regarding the ap and bone healing. All patients were treated by meticulous wound excision with stabilization of fracture and then wound cover, which is done early in 6 patients (before 7 days) and late in 12 patients (after 7 days). local muscle ap was done in 9 patients (50%), local fasciocutanous ap in 6 patients (33/3%) and free ap in 3 (16.7%). CONCLUSION: primary reconstruction of Gustilo type III open tibial fractures had advantages compared with secondary reconstruction. Smoking plays an important role in increasing complication.

Timing of antibiotic administration, wound debridement, and the stages of reconstructive surgery for open long bone fractures of the upper and lower limbs

BACKGROUND

Open fractures of the major long bones are complex limb-threatening injuries that are predisposed to deep infection. Treatment includes antibiotics and surgery to debride the wound, stabilise the fracture and reconstruct any soft tissue defect to enable infection-free bone repair. There is a need to assess the effect of timing and duration of antibiotic administration and timing and staging of surgical interventions to optimise outcomes.

OBJECTIVES

To assess the effects (risks and benefits) of the timing of antibiotic administration, wound debridement and the stages of surgical interventions in managing people with open long bone fractures of the upper and lower limbs.

SEARCH METHODS

We searched the Cochrane Central Register of Controlled Trials (CENTRAL), MEDLINE, Embase and clinical trial registers in February 2021. We also searched conference proceedings and reference lists of included studies.

SELECTION CRITERIA

We included randomised controlled trials (RCTs) or quasi-RCTs that recruited adults with open fractures of the major long bones, comparing: 1) timings of prophylactic antibiotic treatment, 2) duration of prophylactic antibiotic treatment, 3) timing of wound debridement following injury or 4) timing of the stages of reconstructive surgery.

DATA COLLECTION AND ANALYSIS

We used standard methodological procedures expected by Cochrane. We aimed to collect data for the following outcomes: limb function, health-related quality of life (HRQoL), deep surgical site infection, delayed or non-union, adverse events (in the short- and long-term course of recovery), and resource-related outcomes.

MAIN RESULTS

We included three RCTs of 613 randomised participants with 617 open fractures. Studies were conducted in medical and trauma centres in the USA and Kenya. Where reported, there was a higher proportion of men and a mean age of participants between 30 and 34 years old. Fractures were in the upper and lower limbs in one study, and were tibia fractures in two studies; where reported, these were the result of high-energy trauma such as road traffic accidents. No studies compared the timing of antibiotic treatment or wound debridement. Duration of prophylactic antibiotic treatment (1 study, 77 participants available for analysis) One study compared antibiotic treatment for 24 hours with antibiotic treatment for five days. We are very uncertain about the effects of different durations of antibiotic treatment on superficial infections (risk ratio (RR) 1.19, 95% CI 0.49 to 2.87, favours 5 day treatment; 1 study, 77 participants); this was very low-certainty evidence derived from one small study with unclear and high risks of bias, and with an imprecise effect estimate. This study reported no other review outcomes. Reconstructive surgery: timing of the stages of surgery (2 studies, 458 participants available for analysis) Two studies compared the timing of wound closure, which was completed immediately or delayed. In one study, the mean time of delay was 5.9 days; in the other study, the time of delay was not reported. We are very uncertain about the effects of different timings of wound closure on deep infections (RR 0.82, 95% CI 0.37 to 1.80, favours immediate closure; 2 studies, 458 participants), delayed union or non-union (RR 1.13, 95% CI 0.83 to 1.55, favours delayed closure; 1 study, 387 participants), or superficial infections (RR 6.45, 95% CI 0.35 to 120.43, favours delayed closure; 1 study, 71 participants); this was very low-certainty evidence. We downgraded the certainty of the evidence for very serious risks of bias because both studies had unclear and high risks of bias. We also downgraded for serious imprecision because effect estimates were imprecise, including the possibility of benefits as well as harms, and very serious imprecision when the data were derived from single small study. These studies reported no other review outcomes.

AUTHORS' CONCLUSIONS

We could not determine the risks and benefits of different treatment protocols for open long bone fractures because the evidence was very uncertain for the two comparisons and we did not find any studies addressing the other possible comparisons. Well-designed randomised trials with adequate power are needed to guide surgical and antibiotic treatment of open fractures, particularly with regard to timing and duration of antibiotic administration and timing and staging of surgery.

Forecasting the flap: predictors for pediatric lower extremity trauma reconstruction

Background

Predicting the need for post-traumatic reconstruction of lower extremity injuries remains a challenge. Due to the larger volume of cases in adults than in children, the majority of the medical literature has focused on adult lower extremity reconstruction. This study evaluates predictive risk factors associated with the need for free flap reconstruction in pediatric patients following lower extremity trauma.

Methods

An IRB-approved retrospective chart analysis over a 5-year period (January 1, 2012 to December 31, 2017) was performed, including all pediatric patients (<18 years old) diagnosed with one or more lower extremity wounds. Patient demographics, trauma information, and operative information were reviewed. The statistical analysis consisted of univariate and multivariate regression models to identify predictor variables associated with free flap reconstruction.

Results

In total, 1,821 patients were identified who fit our search criteria, of whom 41 patients (2.25%) required free flap reconstruction, 65 patients (3.57%) required local flap reconstruction, and 19 patients (1.04%) required skin graft reconstruction. We determined that older age (odds ratio [OR], 1.134; P =0.002), all-terrain vehicle accidents (OR, 6.698; P<0.001), and trauma team activation (OR, 2.443; P=0.034) were associated with the need for free flap reconstruction following lower extremity trauma in our pediatric population.

Conclusions

Our study demonstrates a higher likelihood of free flap reconstruction in older pediatric patients, those involved in all-terrain vehicle accidents, and cases involving activation of the trauma team. This information can be implemented to help develop an early risk calculator that defines the need for complex lower extremity reconstruction in the pediatric population.

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.

Intentional Temporary Limb Deformation for Closure of Soft-Tissue Defects in Open Tibial Fractures

OBJECTIVES

(1) Evaluate intentional temporary limb deformation for closure of soft-tissue defects as a reconstruction strategy in open tibia fractures and (2) analyze the deformity parameters required for such reconstruction.

DESIGN

Multicenter retrospective cohort.

SETTING

Level I trauma center.

PATIENTS/PARTICIPANTS

Nineteen patients 18 years of age and older at the time of initial trauma, with a Gustilo-Anderson type IIIB or IIIC open tibia fracture treated with hexapod external fixation and intentional bony deformity created to facilitate soft-tissue closure.

INTERVENTION

Intentional limb deformation for soft-tissue closure, followed by gradual correction with a hexapod external fixator.

OUTCOME MEASUREMENTS

Radiographic healing, radiographic assessment of limb alignment, and functional and bony Application of the Method of Ilizarov Group score.

RESULTS

The average age was 45.3 (20-70), and 79% of patients were men. The most common mechanism of injury was motor vehicle accidents. The distal 1 of 5 of the tibia was the most common fracture location, with 37% of these involving the articular surface at the plafond. After wound closure, deformity correction was initiated after 30 days on average. Varus and apex posterior were the most common initial deformity required for primary soft-tissue closure. Bony and functional Application of the Method of Ilizarov Group outcomes were good or excellent in 94% of patients.

CONCLUSION

Intentional deformation followed by a gradual correction can be an effective strategy to obtain bone union and soft-tissue coverage in certain open fractures. This technique, in essence, converts these injuries from type IIIB to IIIA. This strategy obviates the need for flap coverage and results in satisfactory outcomes.

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

BACKGROUND

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

METHODS

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

RESULTS

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

CONCLUSION

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

A novel low-profile external skeletal fixator for type IIIB open tibial fractures: A biomechanical and clinical pilot study

BACKGROUND

Although external fixator is standard for managing staged treatment of open tibial fracture, the main disadvantage of this device is too bulky to be tolerated by most patients for longtime use. The purposes of this pilot study were to compare the biomechanical properties of a novel low-profile external fixator (LP-ESF) with a traditional ESF and also to evaluate its performance in patients with Gustilo type IIIb tibial open fractures.

METHODS

A prospective clinical pilot study started from January 2015 to December 2017, and 18 patients with Gustilo type IIIb open tibial fractures underwent the fixation with a novel LP-ESF system. The biomechanical properties of the LP-ESF were compared with the Synthes External Fixation System according to the standard ASTM F1541-02. These patients were divided into two groups according to the size of bony defect. The postoperative clinical outcomes were subsequently collected.

RESULTS

The biomechanical properties of the LP-ESF were comparable with those of Synthes External Fixation System and had an improved the axial/torsional stiffness and ultimate strength. In the clinical study, all patients with LP-ESF had fracture union. The duration of application of LP-ESF was 3.5 to 18 months until fracture union. In 10 of 18 patients, their fractures were immobilized with the LP-ESF until bone union, and no pin tract infection and no chronic osteomyelitis were recorded. The 36-Item Short Form Health Survey life quality and health survey were good to excellent in these patients. Notably, the LP-ESF allowed a patient with severe bone and soft-tissue defects to preserve the leg and joints function.

CONCLUSION

In this study, we found that the novel LP-ESFs had improved clinical outcomes. The long-term LP-ESF application seems to be tolerable in our patients. This novel approach permits better controls in deep infection and faster healing of fractures, and thus may provide a viable alternative treatment for Gustilo type IIIb open tibial fractures.

Acute limb shortening or creation of an intentional deformity to aid in soft tissue closure for IIIB/IIIC open tibia fractures

BACKGROUND

Ring fixator techniques can precisely correct complex long bone deformities. In select patients, controlled shortening or intentional fracture deformation with delayed correction can also aid in complex wound coverage and limb salvage.

METHODS

This retrospective cohort study analyzed all patients who underwent acute limb shortening or intentional temporary fracture deformation between 2005 and 2020. Patients were divided into three groups based on reason for acute shortening or intentional deformity: (1) skeletal indications alone, with traditional flap coverage; (2) skeletal and soft tissue indications, to augment traditional reconstructive measures; and (3) skeletal and soft tissue indications, to avoid microsurgery altogether. Comorbidities, orthopedic and reconstructive methods, and functional outcomes were recorded.

RESULTS

Eighteen patients were identified: six in Group 1, five in Group 2, and seven in Group 3. Fractures were primarily in the distal third of the tibia. On initial assessment, all wounds would have required free tissue transfer. Group 1 patients were reconstructed with free flaps. Among Group 2, closure was accomplished by skin grafting (N = 1), local flaps (N = 1), pedicled muscle flaps (N = 1), and free flaps (N = 2). In Group 3, five wounds were closed primarily and two were skin grafted. All limbs were shortened, averaging 25.1 mm; seven were intentionally deformed, most commonly varus (10-20°). After skeletal correction, residual leg length discrepancy averaged 5.7 mm. No patients required amputation.

CONCLUSIONS

Acute skeletal shortening with or without intentional temporary deformation in select IIIB/IIIC open tibial fractures can facilitate soft tissue coverage and limb salvage in patients who might otherwise require amputation.

Evaluation of the American Society of Anesthesiologists Physical Status Classification System in Risk Assessment for Lower Extremity Reconstruction with Free Tissue Transfer

BACKGROUND

 The applicability of free flap reconstruction for lower extremity (LE) defects in high-risk patients continues to require ongoing review. The aim of this study was to analyze the risk factors, management, and outcome of LE free flap reconstruction in high-risk (American Society of Anesthesiologists [ASA] class 3 or 4) patients.

METHODS

 A retrospective chart review was performed for all patients who underwent LE reconstruction in our Institution (Level I Trauma Center) from 2013 to 2019. Medical records and the authors' prospectively maintained database were analyzed with respect to ASA class, comorbidities, and postoperative complications. All patients were treated using the same pre-, intra-, and postoperative multidisciplinary approach.

RESULTS

 A total of 199 patients were analyzed. Sixty-six flaps were transferred in 60 patients with an ASA class 3 or higher. High-risk patients did not present a higher rate of flap loss or LE amputation. The overall flap success rate was 92%. There were five flap losses in high-risk patients. Three of these five patients underwent a successful second free flap reconstruction. The overall success rate of LE reconstruction in high-risk patients was 90%. Four patients with successful free flap ended up in LE amputation due to bone infection and two patients underwent an amputation after the first free flap failure.

CONCLUSION

 Free flap reconstruction for LE defects in high-risk patients is a safe and reliable procedure for selected patients when an experienced multidisciplinary team is involved. Bone infection was the only variable associated with LE amputation.

The esthetic outcome of lower limb reconstruction

BACKGROUND

In recent years, the progress of anatomical knowledge and microsurgical techniques, in particular the development of perforator flaps, has risen the number of flaps available for lower leg reconstruction. The esthetic consequences of flap choice and harvest do have an impact on patients' quality of life. Nowadays, more researchers evaluate the esthetic changes following lower limb reconstruction.

OBJECTIVES

This review aims to summarize the available evidence on the esthetic outcome of lower limb reconstruction.

DATA SOURCES

A systematic review was planned to identify the most relevant indexed articles on this subject. The search was performed on Pubmed database without date of publication limits.

STUDY ELIGIBILITY CRITERIA

All papers about reporting information about the esthetic outcome of lower limb reconstruction were selected. Case reports and the articles not including specific information about complications, secondary procedures, and outcomes were excluded. The articles were categorized according to their topic and date of publication. The full texts of all the articles were obtained and read thoroughly. The references for each article were screened to identify articles that were eventually left outside our database search.

PARTICIPANTS, AND INTERVENTIONS

One hundred and eight articles were retained for the definitive review. Eleven review articles were kept because they represented a good source of information. Thirty-three articles were added after reading the full texts. The articles appear highly heterogeneous and at, this stage, only a critical and qualitative analysis could be performed.

RESULTS

We found information about 7895 lower reconstructions, 1295 local flaps, 6546 free flaps.

LIMITATIONS

The esthetic evaluation is intrinsic subjective. Many psychological and cultural factors influence both the patient and the surgeon. There is not a validated assessment tool for the esthetic outcome of lower leg reconstruction. Therefore, no quantitative analysis was performed.

CONCLUSIONS

Some ancient techniques are today obsolete, like the rectus abdominis free muscle flaps and perhaps free forearm flap, others are always useful, like gracilis and latissimus dorsi free flap. ALT flap is the most versatile perforator flap today available, but the SCIP flap is gaining the favor of a growing number of surgeons. Local flaps will be always performed with success but their indications should not be pushed beyond the medium-size defects. The best cosmetic outcome for each patient cannot necessarily be obtained neither with the easiest techniques nor with the most technically demanding ones. It is necessary to develop validated tools to assess the cosmetic outcome of lower limb reconstruction.

Single-stage "Fix and Flap" gives Good Outcomes in Grade 3B/C Open Tibial Fractures: A Prospective Study

Introduction:

Grade 3B/C open tibial fractures with grossly contaminated degloving injuries have poor outcomes, with or without vascular injuries. Treatment decision oscillates between limb salvage and amputation. The standard protocol of repeated debridement and delayed wound cover is a challenge in developing countries due to overcrowded emergencies and limited operating room availability. We present results of our modified protocol involving primary stabilisation with external fixation and immediate wound cover as an aggressive modality of treatment.

Material and Methods:

Thirty-three patients with severe open tibial shaft fractures were managed using a standardised protocol of emergent debridement, external fixation and immediate wound cover with free distant/local rotational muscle flaps and fasciocutaneous flaps, and with vascular repair in Grade 3C fractures. Intra-articular fractures were excluded. Patients were followed for a minimum of three years, with an assessment of clinical, radiological and functional outcomes.

Results:

Wound cover was achieved with 24 distant free muscle flaps, four local rotational muscle flaps and five fasciocutaneous flaps. All fractures united with an average time to union of 40.3 weeks (16-88). Fifteen patients (45.4%) underwent only a single major surgery using primary definitive external fixation. Deep infection was seen in four patients (12.1%). Nineteen patients had excellent to good outcomes, six were fair, and eight were poor.

Conclusion:

“Fix and Flap” in the same sitting, using immediate wound cover and external fixation, has given good results in our hands despite the delayed presentation, the neurovascular deficit and the degloving injury. This may be a better management strategy in overcrowded tertiary care centres of developing countries, with a single surgical procedure in almost half the cases.

The use of the Ganga Hospital Score to predict the treatment and outcome of open fractures of the tibia

AIMS

Open fractures of the tibia are a heterogeneous group of injuries that can present a number of challenges to the treating surgeon. Consequently, few surgeons can reliably advise patients and relatives about the expected outcomes. The aim of this study was to determine whether these outcomes are predictable by using the Ganga Hospital Score (GHS). This has been shown to be a useful method of scoring open injuries to inform wound management and decide between limb salvage and amputation.

METHODS

We collected data on 182 consecutive patients with a type II, IIIA, or IIIB open fracture of the tibia who presented to our hospital between July and December 2016. For the purposes of the study, the patients were jointly treated by experienced consultant orthopaedic and plastic surgeons who determined the type of treatment. Separately, the study team (SP, HS, AD, JD) independently calculated the GHS and prospectively collected data on six outcomes for each patient. These included time to bony union, number of admissions, length of hospital stay, total length of treatment, final functional score, and number of operations. Spearman's correlation was used to compare GHS with each outcome. Forward stepwise linear regression was used to generate predictive models based on components of the GHS. Five-fold cross-validation was used to prevent models from over-fitting.

RESULTS

The mean follow-up was 11.4 months (3 to 31). The mean time to union was 9.7 months (3 to 21), the mean number of operations was 2.8 (1 to 11), the mean time in hospital was 17.7 days (5 to 84), the mean length of treatment was 92.7 days (5 to 730), the mean number of admissions was 1.7 (1 to 6), and the mean functional score (Lower Extremity Functional Score (LEFS)) was 60.13 (33 to 80). There was a significant correlation between the GHS and each of the outcome measures. A predictive model was generated from which the GHS could be used to predict the various outcome measures.

CONCLUSION

The GHS can be used to predict the outcome of patients who present with an open fracture of the tibia. Our model generates a numerical value for each outcome measure that can be used in clinical practice to inform the treating team and to advise patients.

Two-Stage Combined Ortho-Plastic Management of Type IIIB Open Diaphyseal Tibial Fractures Requiring Flap Coverage: Is the Timing of Debridement and Coverage Associated With Outcomes?

OBJECTIVE

To delineate whether timing to initial debridement and definitive treatment had an effect on patient outcomes in those undergoing 2-stage ortho-plastic management of Gustilo-Anderson type IIIB open tibial diaphyseal fractures.

DESIGN

Retrospective comparative cohort study over a 2-year period.

SETTING

Level 1 trauma center.

PATIENTS/PARTICIPANTS

A total of 148 patients were identified. After exclusion of ankle fractures, nondiaphyseal fractures and those who did not undergo 2-stage ortho-plastic management, 45 patients were eligible for final analysis.

INTERVENTION

Time to initial debridement and definitive management.

MAIN OUTCOME MEASUREMENT

Deep infection. Secondary outcomes being nonunion and flap failure. Multiple linear regression was used for outcomes. We assumed a priori that P values of less than 0.05 were significant.

RESULTS

Mean age was 54 years (SD 23.0), with 28 men and 17 women. Over a mean 2-year follow-up, there were 4 (4/45) deep infections, 2 infection-associated flap failures, and 1 vascular flap failure. All patients progressed to union. The mean time to initial debridement for the whole cohort was 19 hours (SD 12.3), and the mean time to definitive reconstruction was 65 hours (SD 51.7). Longer time to both initial debridement and definitive reconstruction was not found to be significantly associated with deep infection, infected flap failure, or nonunion.

CONCLUSIONS

Using a 2-stage ortho-plastic operative algorithm, timing to initial debridement and definitive fixation with soft-tissue coverage was not associated with negative outcomes.

LEVEL OF EVIDENCE

Foot and ankle infections: Debridement, early fixation and rifampicin provide earlier recovery of function and quality of life

BACKGROUND

Infection after foot and ankle fractures is a major concern for orthopedic surgeons. It is widely believed that final osteosynthesis should be delayed until the infection is cured. However, there is no literature that supports this practice. In addition, the delay impairs patient function and quality of life (QoL).

METHODS

In the present study, four cases of ankle infection treated with aggressive debridement, early fixation and antibiofilm antibiotics are described. It is thought that, like other implant related infections, ankle infections can be rapidly treated with the definitive fixation and by curing the infection to make for a fast recovery of QoL and function.

RESULTS

The infections were caused by MSSA and Pseudomonas aeruginosa in case 1, MSSA in case 2 and MRSA as well as K. pneumonia in case 3. Case 4 was a culture negative infection. They were susceptible to antibiofilm antibiotics (the gram-negative bacilli susceptible to ciprofloxacin and the gram-positive cocci susceptible to rifampicin). Cases 1, 3 and 4 were treated with a tibio-talo-calcaneal arthrodesis and case 2 was treated with a de-rotational fibular osteotomy and a medial closing wedge supramalleolar osteotomy. All cases improved at a median time of 4 weeks in terms of quality of life (SF-36) and function (AOFAS). At 2-years follow-up, no recurrence of infection was observed in any of the cases. All the cases achieved fusion or osteotomy healing at final follow-up.

CONCLUSIONS

Early fixation after debridement combined with antibiofilm antibiotics can be performed in foot and ankle inflections to provide early recovery of QoL and function in patients.

Measuring outcomes following tibial fracture

AIM

The aim of this study was to determine how outcome is measured following adult tibial fracture in the modern era of functional outcome measurement and patient reported outcomes.

METHODS

A systematic review of publications since 2009 was performed, looking specifically at acute, adult tibial shaft fractures. Ovid Medline, Embase, PubMed and PsycINFO databases were searched for relevant titles which were then screened by two authors with adjudication where necessary by a third. Relevant articles were reviewed in full and data was extracted concerning the study participants, study design and any measures that were used to quantify the results following fracture. The results were collated and patient reported outcome measures were assessed using the COnsensus-based Standards for the selection of health Measurement INstruments (COSMIN) standards.

RESULTS

A total of 943 titles and articles were reviewed, with 117 included for full analysis. A wide range of clinical and radiological "outcomes" were described, along with named clinician- and patient-reported outcome measures. There was considerable heterogeneity and lack of detail in the description of the simplest outcomes, such as union, infection or reoperation. Reported clinician and patient reported outcome measures are variably used. None of the identified patient reported outcome measures have been validated for use following tibial fracture.

CONCLUSION

We recommend definition of a core outcome set for use following tibial fracture. This will standardise outcome reporting following these injuries. Furthermore, there is need for a validated patient reported outcome measure to better assess patient important outcomes in this patient group.

Knee Sepsis after Suprapatellar Nailing of an Open Tibia Fracture: Treatment with Acute Deformity and External Fixation

Case

A 31-year-old male was involved in a dirt bike accident and sustained an isolated type II open mid-distal tibia fracture. The patient underwent suprapatellar intramedullary nailing and subsequently developed knee sepsis.

Conclusion

This patient was managed with irrigation and debridements of the knee, fracture site, and intramedullary canal. A resultant soft-tissue defect over the fracture site obviated primary closure. Creation of an acute deformity stabilized by a Taylor spatial frame allowed primary wound closure. After soft tissue healing occurred, the frame was used to correct the intentional deformity and maintain reduction until full healing occurred.

Lower extremity flap coverage following trauma

Lower extremity injuries requiring soft tissue coverage comprises a significant proportion of these injuries worldwide. Reconstruction of the soft tissues overlying fractures is essential for bone union and reduction of infection thus improving function and reducing the rate of limb amputation. A systematic exploration and excision of the wound should be jointly performed by senior surgeons from Orthopaedic and Plastic Surgery. The grading of the injury and subsequent reconstruction of bone and soft tissue should only be planned once a thorough excision of all necrotic tissue has been performed. It is this thorough debridement and early flap coverage that contributes to infection-free bony union. This article explores the options for soft tissue flap coverage for the different zones in the lower limb.

Sequential management of tibial fractures using a temporary unicortical external fixator

Introduction: The development of damage control orthopedics (DCO) procedures has led to the development of temporary unicortical external fixators (TUEFs) intended to limit deep infectious complications and facilitate early conversion to internal fixation.

Methods: A retrospective study was conducted in two French military trauma centers, including on patients being treated for tibial fractures with a TUEF (UNYCO^® − Orthofix^®) followed by an early conversion to intramedullary nailing.

Results: Eleven patients with an average age of 41 were included between September 2015 and June 2017. A total of 12 TUEFs were implanted for one closed fracture and 11 open fractures, including one type I, eight types II, and two Gustilo types IIIB. The indication of DCO was related to hemodynamic instability in three cases, to the severity of soft tissue lesions in eight cases, and to the context of treatment in one case. The conversion to IM nailing was made after an average of 7.6 days. No significant loss of reduction was observed until internal osteosynthesis, which was performed with “fixator in place” in ten cases. The coverage of Gustilo type III injuries was performed by free flap transfers at the same time as IM nailing. All the patients were reviewed with an average follow-up of 16.5 months. Bone union was achieved in all cases. Two IM nailing dynamizations were carried out, but no bone grafting was required. Two cases of pandiaphysitis were observed and treated without functional complications.

Discussion: Despite a limited number of patients, this study demonstrates the reliability of the TUEF to maintain the reduction of tibial fractures and facilitate early conversion to IM nailing. Unicortical fixation does not prevent septic complications related to the severity of soft tissue injuries.

The tibial bayonet method of wound closure

Management of open lower limb fractures with soft tissue defects can be a technically challenging orthopaedic problem. Limited availability of orthoplastic services means that alternatives to the fix and flap concept are required in order to prevent infected non-unions from developing. The proposed 'bayonet apposition' allows the surgeon to temporarily shorten the limb without angulating the limb or creating a bone defect and removing viable bone. The viable bone edges are overlapped in a bayonet-like manner in order to appose the wound and skin edges. The limb length is restored by gradually distracting the bone segments once the soft tissues have healed. This is facilitated with a hexapod fixator for stabilization of the fracture and distraction. Prerequisites for utilizing this method are circumferential soft tissue damage to the lower limb with viable distal tissue. The bayonet method allows primary closure of a wound and rapid restoration of the native length of the limb.

Clinical and Research Approaches to Treat Non-union Fracture

PURPOSE OF REVIEW

Impaired healing outcomes or even non-unions after bone injury are still a highly relevant problem in the daily clinical life. Especially within an aging population, the occurrence of bone fractures increases and thus novel treatment approaches to overcome compromised bone regeneration are needed.

RECENT FINDINGS

The gold standard to treat delayed or non-healing bone injuries is still the use of autologous bone grafts to foster regeneration. Besides its successful treatment outcome, it also has disadvantages: a second surgery is needed in order to harvest the bone material and the material is highly limited. Looking into the recent literature, a multitude of different research approaches were already conducted to identify new possible strategies to treat impaired bone regeneration: application of mesenchymal stromal cells, platelet lysates, growth factors, interference in the immune system, or bone formation stimulation by ultrasound. This review gives an overview of the treatment approaches actually performed in the clinic as well as at the bench in the context of compromised bone healing. It clearly highlights the complexity of the nature of non-healing bone fractures as well as patient-dependent factors influencing the healing process.

Wound irrigation does not affect health-related quality of life after open fractures: results of a randomized controlled trial

AIMS

The Fluid Lavage in Open Fracture Wounds (FLOW) trial was a multicentre, blinded, randomized controlled trial that used a 2 × 3 factorial design to evaluate the effect of irrigation solution (soap versus normal saline) and irrigation pressure (very low versus low versus high) on health-related quality of life (HRQL) in patients with open fractures. In this study, we used this dataset to ascertain whether these factors affect whether HRQL returns to pre-injury levels at 12-months post-injury.

PATIENTS AND METHODS

Participants completed the Short Form-12 (SF-12) and the EuroQol-5 Dimensions (EQ-5D) at baseline (pre-injury recall), at two and six weeks, and at three, six, nine and 12-months post-fracture. We calculated the Physical Component Score (PCS) and the Mental Component Score (MCS) of the SF-12 and the EQ-5D utility score, conducted an analysis using a multi-level generalized linear model, and compared differences between the baseline and 12-month scores.

RESULTS

We found no clinically important differences between irrigating solutions or pressures for the SF-12 PCS, SF-12 MCS and EQ-5D. Irrespective of treatment, participants had not returned to their pre-injury function at 12-months for any of the three outcomes (p < 0.001).

CONCLUSION

Neither the composition of the irrigation solution nor irrigation pressure applied had an effect on HRQL. Irrespective of treatment, patients had not returned to their pre-injury HRQL at 12 months post-fracture. Cite this article: Bone Joint J 2018;100-B:88-94.

Hospital Transfer of Open Tibial Fractures Requiring Microsurgical Reconstruction Negatively Impacts Clinical Outcomes

INTRODUCTION

Open tibial fractures are orthopedic emergencies that may present with severe soft tissue damage. Free tissue transfer is often required when local tissues are insufficient and patients may require hospital transfer to tertiary care centers for this purpose. Although the negative impact of inter-facility transfer has been well demonstrated in trauma patients, less is known regarding transfers for lower extremity injury patients. This study investigates differences in outcomes based on transfer status after open tibial fracture.

METHODS

Thirty-four consecutive open tibial fractures requiring free tissue transfer over a 13-year period (2001-2014) were retrospectively reviewed. Patients transferred from outside facilities were compared to non-transferred patients in regards to demographics, injury, surgical characteristics, and outcomes (mean follow-up of 2.5 years). Student t tests and chi square analysis were used to compare means and proportions, respectively.

RESULTS

One-half of patients were transferred from an outside hospital. Transferred and nontransferred patients were not significantly different in regard to age, sex, comorbidities, mechanism of injury, and Gustilo grade. There was no significant difference in the method of bony fixation or free flap used for soft tissue coverage. The time to wound vacuum-assisted closure placement was longer in transferred patients, though this difference was not found to be significant (2.4 vs 3.3 days, P = 0.55). Time to definitive bony fixation was delayed in the transfer group by 9 days (5.2 vs 14.1 days, P = 0.05) and to tissue coverage by 7 days (14.2 vs 20.9 days, P = 0.13). Rates of flap loss and amputation did not differ between the groups. However, transferred patients were more likely to develop osteomyelitis (risk ratio [RR], 3.0; P = 0.03), nonunion (RR, 5.0; P = 0.09), and require hardware removal (RR, 3.3; P = 0.01).

CONCLUSIONS

Transferred and nontransferred patients were not significantly different in their demographics or presentation. However, an analysis of clinical outcomes showed that transfer was associated with increased rates of osteomyelitis, nonunion, and hardware removal. Although likely multifactorial, this study suggests that a delay to definitive fixation and soft tissue coverage contributes to the increased rate of complications and poorer prognosis.

Reconstruction of large diaphyseal bone defect by simplified bone transport over nail technique: A 7-case series

Reconstruction of large diaphyseal bone defect is complex and the complications rate is high. This study aimed to assess a simplified technique of segmental bone transport by monorail external fixator over an intramedullary nail.A prospective study included 7 patients: 2 femoral and 5 tibial defects. Mean age was 31years (range: 16-61years). Mean follow-up was 62 months (range: 46-84months). Defects were post-traumatic, with a mean length of 7.2cm (range: 4 to 9.5cm). For 3 patients, reconstruction followed primary failure. In 4 cases, a covering flap was necessary. Transport used an external fixator guided by an intramedullary nail, at a rate of 1mm per day. One pin was implanted on either side of the distraction zone. The external fixator was removed 1 month after bone contact at the docking site. Mean bone transport time was 11 weeks (range: 7-15 weeks). Mean external fixation time was 5.1months (range: 3.5 to 8months). Full weight-bearing was allowed 5.7months (range: 3.5-13months) after initiation of transport. In one patient, a pin had to be repositioned. In 3 patients, the transported segment re-ascended after external fixatorablation, requiring repeat external fixation and resumption of transport. There was just 1 case of superficial pin infection. Reconstruction quality was considered "excellent" on the Paley-Marr criteria in 6 cases. The present technique provided excellent reconstruction quality in 6 of the 7 cases. External fixation time was shorter and resumption of weight-bearing earlier than with other reconstruction techniques, notably including bone autograft, vascularized bone graft or the induced membrane technique. Nailing facilitated control of limb axis and length. The complications rate was 50%, comparable to other techniques. This study raises the question of systematic internal fixation of the docking site, to avoid any mobilization of the transported segment. The bone quality, axial control and rapidity shown by the present technique make it well-adapted to reconstruction of diaphyseal bone defect.

LEVEL OF EVIDENCE

Four-case series.

The Anconeus Muscle Free Flap: Clinical Application to Lesions on the Hand

BACKGROUND

It can be difficult to select an appropriate flap for various defects on the hand. Although defects of the hand usually must be covered with a skin flap, some defects require a flap with rich blood supply and adequate additive soft tissue volume. The authors present their experience with the anconeus muscle free flap in the reconstruction of various defects and the release of scar contractures of the hand.

METHODS

Ten patients underwent reconstruction of the finger or release of the first web space using the anconeus muscle free flap from May 1998 to October 2013. Adequate bed preparations with thorough debridement or contracture release were performed. The entire anconeus muscle, located at the elbow superficially, was harvested, with the posterior recurrent interosseous artery as a pedicle. The defects were covered with a uniformly trimmed anconeus muscle free flap. Additional debulking of the flap and skin coverage using a split-thickness skin graft were performed 3 weeks after the first operation.

RESULTS

The average flap size was 18.7 cm2 (range, 13.5-30 cm2). All flaps survived without significant complications. Vein grafts for overcoming a short pedicle were necessary in 4 cases.

CONCLUSIONS

The anconeus muscle free flap can be considered a reliable reconstructive option for small defects on the hand or contracture release of the web space, because it has relatively consistent anatomy, provides robust blood supply within the same operative field, and leads to no functional loss at the donor site.

The Management of Soft Tissue and Bone Loss in Type IIIB and IIIC Pediatric Open Tibia Fractures

PURPOSE

Type III B and C open tibia fractures in children pose a challenge to the orthopaedic surgeon. Limb salvage is the initial goal for the majority of patients, but managing soft-tissue defects and bone loss can be a challenge. The purpose of this study was to evaluate the use of circular external fixation in the management of these injuries.

METHODS

In this retrospective review, we examined children with type IIIB and IIIC open tibial fractures treated with circular external fixation and soft-tissue coverage between 1990 and 2010. Chart review included: mechanism and severity of injury, degree of bone and soft-tissue loss, technique and duration of external fixation, additional procedures, clinical and radiographic outcomes, and complications.

RESULTS

Eight patients were identified whose average age at the time of injury was 10.4 years (range, 3.8 to 15.3 y). There were 7 type IIIB and 1 type IIIC fractures. All patients received free or rotational soft-tissue flaps. Average bone loss was 5.4 cm (range, 0 to 12 cm). Three techniques of circular external fixation were used, including: (1) static stabilization to allow for soft-tissue coverage and fracture healing, (2) acute shortening with plan for later limb lengthening, and (3) stabilization of the extremity for soft-tissue coverage and intended bone transport. Seven of 8 limbs were salvaged. Of those 7, all were followed to skeletal maturity and ambulating without assistive devices at final follow-up. Three patients had a clinically relevant leg-length discrepancy (≥2 cm). Four of 8 patients required secondary or contralateral procedures.

CONCLUSIONS

Pediatric type IIIB and IIIC tibia fractures are limb-threatening injuries that require dynamic thinking and management as the bone and soft-tissue injuries evolve. We have proposed a general algorithm to guide the treatment of these severe injuries. In our experience, circular external fixation, in conjunction with this algorithm, provides the appropriate stability and environment for managing soft tissue and bone loss and can facilitate limb salvage.

Single stage management of Gustilo type III A/B tibia fractures: Fixed with nail & covered with fasciocutaneous flap

PURPOSE

To evaluate the role of immediate and definitive management of Gustilo type III A/B tibia fractures with intramedullary nailing and fasciocutaneous flap.

METHODS

From August 2010 to July 2012, 22 patients with Gustilo Grade III A/B tibia fractures were managed with a single stage treatment of ipsilateral fasciocutaneous flap & reamed intramedullary nailing and were included in the study. The severity of the injury was calculated with Ganga Hospital injury severity score.

RESULTS

The mean age of patients was 41 years and the follow-up time ranged from six months to one year. Among the 22 patients, 73% were type III B fractures with upper leg involved in 55% of them. The time interval from injury to completion of surgery was 8-14 h. The incidence of bone infection requiring secondary procedure was 9%; the major and minor soft tissue complication rate was 9% and 14% respectively. The limb salvage rate was 100%.

CONCLUSION

Multidisciplinary management of severe lower limb trauma is important and provides good outcomes. Intramedullary nailing and immediate flap fixation can achieve early bone union and good soft tissue coverage, leading to good outcomes in patient with Grade III A & B tibia fractures.

Negative pressure wound therapy for Gustilo Anderson grade IIIb open tibial fractures

BACKGROUND

Traditionally, Gustilo Anderson grade IIIb open tibial fractures have been treated by initial wide wound debridement, stabilization of fracture with external fixation, and delayed wound closure. The purpose of this study is to evaluate the clinical and radiological results of staged treatment using negative pressure wound therapy (NPWT) for Gustilo Anderson grade IIIb open tibial fractures.

MATERIALS AND METHODS

15 patients with Gustilo Anderson grade IIIb open tibial fractures, treated using staged protocol by a single surgeon between January 2007 and December 2011 were reviewed in this retrospective study. The clinical results were assessed using a Puno scoring system for severe open fractures of the tibia at the last followup. The range of motion (ROM) of the knee and ankle joints and postoperative complication were evaluated at the last followup. The radiographic results were assessed using time to bone union, coronal and sagittal angulations and a shortening at the last followup.

RESULTS

The mean score of Puno scoring system was 87.4 (range 67-94). The mean ROM of the knee and ankle joints was 121.3° (range 90°-130°) and 37.7° (range 15°-50°), respectively. Bone union developed in all patients and the mean time to union was 25.3 weeks (range 16-42 weeks). The mean coronal angulation was 2.1° (range 0-4°) and sagittal was 2.7° (range 1-4°). The mean shortening was 4.1 mm (range 0-8 mm). Three patients had partial flap necrosis and 1 patient had total flap necrosis. There was no superficial and deep wound infection.

CONCLUSION

Staged treatment using NPWT decreased the risks of infection and requirement of flap surgeries in Gustilo Anderson grade IIIb open tibial fractures. Therefore, staged treatment using NPWT could be a useful treatment option for Gustilo Anderson grade IIIb open tibial fractures.

Emergency Soft Tissue Reconstruction Algorithm in Patients With Open Tibia Fractures

Introduction:

Tactic of emergency closing of soft tissue defect allows to significantly improve the treatment results concerning patients with severe open fractures. However, a number of certain factors make the implementation of this tactic rather difficult. Injured people’s unstable conditions are mong these crucial factors which include, polytrauma in lots of cases, absence of exact recommendations for recovery terms, choice of definite tissue flaps and a type of circulation.

The Aim of Study:

is to develop exact, usable and in practice algorithm of emergency reconstruction of leg soft tissues in patients with severe open tibia fractures, based on the usage of the most foolproof and simple methods.

Data (Patients) and Methods:

85 patients with open tibia fractures complicated by soft tissue defects were included in our study. Patients were divided into two groups. The control group consisted of 56 patients. Soft tissue reconstruction in this group was provided without an exact algorithm, after continuous attempts on local healing. After analyzing the treatment process and the treatment results we have developed the algorithm of emergency soft tissue reconstruction. It was used in 29 patients (the study group). This algorithm allows choosing optimal timing for tissue reconstruction and appropriate method to be applied, depending on the patient’s condition, the mechanism of soft tissue defect formation, and its square and localization.

Results:

We observed a statistical decrease in deep wound infection frequency, partial tibia necrosis frequency, chronic osteomyelitis frequency, duration of hospitalization in patients with severe open tibia fractures because of using our algorithm.

A Role for Vacuum-Assisted Closure in Lower Limb Trauma: A Proposed Algorithm

The British Association of Plastic Surgeons and British Orthopaedic Association estimate that 70% of Gustilo 3b tibial fractures require flap coverage. Prior to the introduction of vacuum-assisted closure (V.A.C.®) in the late 1990s, options were limited for the treatment of such injuries in selected individuals with medical comorbidity or complex wounds. VAC has now become an important part of our algorithm for soft tissue reconstruction with excellent results, but its role has not yet been defined in common management pathways. The authors present 3 cases, all different in their mechanism of injury, type of injury, and subsequent management, but all had a successful outcome with VAC.
