A prospective randomized control trial comparing outcomes of casting, pinning, and plating for distal end of radius fractures (AO type A2, A3, C1, or C2) in the elderly population.

PURPOSE: With this prospective randomized control trial (RCT), we aim to provide the outcome analyses of the three most used treatment modalities for distal end of radius (DER) fracture management in the elderly. METHODS: A prospective randomized control trial was performed. Fifty-two patients with DER fractures (AO A2, A3, C1, or C2) were randomized to the casting (n = 17), percutaneous pinning (n = 18), and the volar plating group (n = 17). Radiological measurements measured were radial inclination (RI), radial height (RH), volar tilt (VT), and ulnar variance (UV). The outcome was measured based on range-of-motion, grip strength, Patient-Related-Wrist-Evaluation (PRWE) score, and the Quick-Disabilities-of-the-Arm-Shoulder-Hand (QDASH) score. RESULTS: Immediate post-operative and 1-year-follow-up X-rays showed a significant difference measurement between the groups (p < 0.05). Pairwise comparisons of the casting and pinning groups (p < 0.05) and the casting and plating groups (p < 0.05) revealed significant differences at the 1-year follow-up, but not the pinning and plating groups (p > 0.05). The analysis found significant differences in clinical outcomes after 1 month of follow-up, with the plating group outperforming the other two (p > 0.05). However, after a year of follow-up, all groups had comparable outcomes; however, the plating group showed improved palmar flexion (p < 0.001), radial deviation (p < 0.001), and a lower PRWE score (p < 0.05), indicating better wrist function. Complications were more in casting group. CONCLUSION: The study found a radiologically significant difference between groups throughout the follow-up, but it did not affect functional results. Clinical outcomes were similar across the groups, with plating showing better palmar flexion and radial deviation. Grip strength was also better in the plating group, but statistically insignificant. The study suggests plating should be chosen over other treatments for high-demand patients.

Role of impaction bone grafting of allografts in the management of benign lesions of the proximal femur.

Purpose of study: The use of allografts to reconstruct benign lesions of the proximal femur after curettage has seldom been reported. We report our experience of impaction bone grafting of only allografts combined with osteosynthesis to manage benign lesions involving the proximal femur. Materials and methods: Between 2013 and 2019, 35 patients of a mean age of 23.8 years (14-41) who had a biopsy proven benign pathology and a median pre-operative Mirels' score of 9 (8-11) were managed using extended curettage, impaction bone grafting of allografts combined with osteosynthesis through a lateral approach. Radiographs were assessed to see for any recurrence at follow-ups, and functional outcomes were assessed using Musculoskeletal Tumour Society (MSTS) score and Harris hip score (HHS). Results: At a mean follow-up was 41.5 months (23-80), patients demonstrated favorable functional outcomes with a mean MSTS of 28.3 (18-30) and a mean HHS of 94.3 (66-100) at the last follow-up. Two cases (GCT = 1; fibrous dysplasia = 1) had a recurrence of disease. Allografts demonstrated a particular integration pattern on radiographs that involved an intermediate period of lucency followed by consolidation and integration with the parent bone. Conclusion: Impaction grafting of allografts in benign lesions of the proximal femur allows adequate bony consolidation of the cavity after extended curettage and can be effectively used as a permanent solution to manage such lesions in most cases. The intermediate period of lucency seen on radiographs must not be confused for recurrence, and patients must be followed up continuously. Study design: Retrospective Case Series. Level of evidence: Level IV.

How Safe is Antegrade Femoral Nailing in Ipsilateral Acetabulum Fractures Requiring Kocher-Langenbeck Approach? An Analysis of 23 Fractures.

Objective: The ipsilateral acetabulum and femur fracture (IAFF) is an uncommon entity. This combination challenges the surgeon in the optimal management of each injury component, fixation sequence, surgical approaches, implant choices and complications. Inappropriate approach for one fracture may affect the fixation of another or modify the overall outcome. In this perspective, we aim to analyze our results in patients who underwent acetabulum fixation with Kocher-Langenbeck (K-L) approach and antegrade femur nailing (AFN), emphasizing the incidence of infection, skin necrosis and heterotopic ossification (HO). Methods: During the five years, 22 patients with 23 IAFF (mean age of 36.5 years) were treated operatively. All the patients underwent K-L approach for acetabulum fixation and AFN for femur fracture. All the patients were treated under the supervision of a pelvi-acetabular trauma consultant. Demographic data, injury, surgical, and postoperative details were collected. The quality of acetabular reduction was evaluated using Matta's criteria. The radiological outcome, obtained at final follow-up, was graded according to Matta's criteria. Functional outcome was evaluated by Merle d'Aubigné and Postel system. HO was graded according to the Brooker system. Complications recorded were DVT, skin necrosis, infection, arthritis, HO, AVN and need for additional surgery. Results: Out of 23, 11 had posterior dislocation, 6 had quadrilateral plate injury with central protrusion and six without dislocation. Femur fractures include 9-midshaft, 4-proximal third, 3-distal third, 3-trochanteric fractures and 4-segmental fractures. There were 11 elementary and 12 associated acetabulum fractures. 21 fractures underwent staged-fixation. Single-stage fixation was done in 2. In all cases treated with staged-fixation, AFN was done first. The mean duration of follow-up was 28 months (16-57). All femur fractures united with a mean union time of 21.3 weeks (11-37). The radiological outcome was excellent in 13, good in 4, fair in 3 and poor in 3. The functional outcome was excellent in 3, good in 11, fair in 4 and poor in 4 patients. None had skin necrosis. Three patients had infection. 14 (60.8%) hips had HO, with clinically significant HO (grade 4) in 2(8.6%). Six (26%) patients had arthritic changes. Four (17.3%) hips had avascular necrosis. Conclusion: AFN is a viable option in IAFFs requiring a K-L approach under the supervision of a pelvi-acetabular surgeon. This combined approach per se does not demonstrate an increased risk of infection, wound healing problems or HO.

Pin Leverage Technique: A Simple Percutaneous Technique for Elevation of Posterolateral Tibial Plateau Fractures.

Depressed lateral tibial plateau fractures with a large central or posterior fragment can be seen in isolation or association with complex proximal tibia fractures. Conventionally elevation of the large depressed fragment is done by bone tamp through a medial metaphyseal window in isolated fractures, or the fractured window in associated complex fracture scenarios. Though various instruments have been devised for this purpose, reaching the posterior aspect of lateral condyle through the medial metaphyseal window is not always easy, considering the difficulty in aiming and trajectory. Excessive maneuvering can result in the widening of the medial metaphyseal window, leaves a large metaphyseal void, intraarticular penetration of elevating device, and comminution of the depressed fragment. Described herein is an alternate percutaneous technique for effective reduction of selected lateral tibial plateau depression fractures using Steinmann pin. Twenty- one patients with at least 1-year follow-up with successful outcomes have benefitted from this reduction technical tip thus far.

Management of pelvic injuries in hemodynamically unstable polytrauma patients - Challenges and current updates.

Pelvic injuries are notorious for causing rapid exsanguination, and also due to concomitant injuries and complications, they have a relatively higher mortality rate. Management of pelvic fractures in hemodynamically unstable patients is a challenging task and has been variably approached. Over the years, various concepts have evolved, and different guidelines and protocols were established in regional trauma care centers based mainly on their previous experience, outcomes, and availability of resources. More recently, damage control resuscitation, pelvic angioembolization, and acute definitive internal fixation are being employed in the management of these unstable injuries, without clear consensus or guidelines. In this background, we have performed a computerized search using the Cochrane Database of Systematic Reviews, Scopus, Embase, Web of Science, and PubMed databases on studies published over the past 30 years. This comprehensive review aims to consolidate available literature on the current epidemiology, diagnostics, resuscitation, and management options of pelvic fractures in polytraumatized patients with hemodynamic instability with particular focus on damage control resuscitation, pelvic angioembolization, and acute definitive internal fixation.

Uncommon Pattern of Anterior Compression Fractures of the Tibial Plateau: A Report of 7 Cases and Review of Literature.

Introduction: Anterior fractures of the tibial plateau are either compression or avulsion injuries. Anterior compression fractures of the tibial plateau (ACFT) are rare being traditionally described as involving the rim and often associated with ligament injuries. We have presented 7seven cases of the "large'' type of ACFT, an uncommon pattern of ACFT. Materials and Methods: 7Seven cases of large type ACFTs were identified on retrospectively analyzing the institutional database from 2014 to 2019. The bony and ligamentous injury patterns, fixation, and functional outcomes of these cases have been analyzed. Results: All were males with a mean age of 40 years. Along with the bony injury, we had posterior cruciate ligament (PCL) injuries in three cases and anterior cruciate ligament ACL with medial collateral ligament (MCL) injury in two cases. Our protocol was bony fixation first and later ligament reconstruction based upon knee instability pattern. The locking plates were used in 4 cases and screw fixation in three cases. One patient underwent PCL and MCL reconstruction and another patient underwent PCL reconstruction. The mean union time was 13 weeks. The mean ROM was 128° degrees. Rasmussen's clinical and radiological scores showed good to an excellent outcome (Mean scores: 28.42, 8.7). No patients had apparent instability at follow-up on clinical examination and stress X-rays. Conclusion: Large ACFTs are rare and associated with anterior joint depression and ligament injuries. Their management significantly differs from that of small type ACFTs (Rim compression injuries) where only ligament reconstruction is needed. Recognition of this pattern is essential for the appropriate management and good functional outcome.

The role of a trauma review system and development of intra-operative checklists in improving the quality of fracture fixations in a high volume tertiary centre.

INTRODUCTION: In high volume centres, audits are essential to ensure good surgical techniques and fracture fixations to avoid complications, revision surgeries and poor outcomes. A method to assess fixations for fractures of different regions employing different implants and surgical demands is a challenge. We present here a simple method of review and follow-up work flow of more than 6000 fixations every year that helped in improving outcomes and also provide training for residents and junior staff. MATERIALS AND METHODS: The results of 6348 fracture fixations in 2014, led to a trauma review system in January 2015 to classify all fracture fixations by senior consultants into three categories: category A (good fixations); category B (acceptable fixations; need further follow-up); category C (poor/unacceptable fixations needing revision) combined with a teaching program. A strategy was evolved that included the following practices: (1) identifying 'red flag' fractures that led to frequent failures, (2) routine senior surgeons' involvement in such fractures, (3) evolving 'intra-operative checklists', (4) requirement of senior surgeons' intervention if there was a 'fiddle time' of more than 20 min, and (5) approval of post-fixation c-arm image by a senior person before closure. The impact of these rules on the fixations for 2015, 2016 and 2017 were prospectively analysed. RESULTS: In the years 2015, 2016 and 2017 the number of fracture fixations performed were 6579, 6978 and 7012, respectively. There was a significant increase (p < 0.001) in the number of category A fixations (87.7%, 94.6% and 96.3% in 2015, 2016 and 2017, respectively) and also a decrease in the number of category C fixations (2.23%, 0.7% and 0.2% in 2015, 2016 and 2017, respectively). The quality of fixations of the 'red flag' fractures also improved. CONCLUSION: We present here a very effective, tested, simple and easily reproducible method of audit and follow-up work flow that can be used in all high turnover trauma centres to improve outcomes and can also serve as a teaching resource for junior staff. STUDY DESIGN: Prospective study. LEVEL OF EVIDENCE: Level II.

Morphology Specific Lateral Wall Reconstruction Techniques Using Cerclage Wires in Unstable Trochanteric Fractures.

Trochanteric lateral wall fracture (LWF) indicates instability and is found to be an important predictor of reoperations following trochanteric fracture fixation. A single unified technique for lateral wall reconstruction may not adequately stabilize all the fracture patterns. We have presented morphology specific lateral wall reconstruction techniques using cerclage wire around proximal femoral nails. Various LWF patterns have been simplified into three types. Type-specific lateral wall reconstruction techniques using cerclage wire were adopted in 49 consecutive unstable trochanteric fractures presented to our institute between 2016 and 2018. We analyzed the fracture pattern, fixation method used, union time, and complications. The functional outcome was analyzed using the Harris hip score (HSS). The mean follow-up period was 13 months (range 10-36 months). The mean age of the population was 66 years (range 36-91 years). There were 15 patients with type 1 LWF pattern, 26 patients with type 2, and 8 were of type 3 pattern. The mean operating time was 66 min. The mean union time was 14 weeks (10-24 weeks). HSS was excellent in 9 patients, good in 33 patients, fair in 4 patients, and poor in 5 patients. Complications include one patient with avascular necrosis (AVN) of the femoral head, varus collapse with non-union in one patient, screws back out in one patient, superficial infection in 4 patients, and distal screw breakage in one patient. Type 2 is the most common LWF type in our study. In unstable trochanteric fractures, morphology specific lateral wall reconstruction using cerclage wire loops around the proximal femoral nail is a simple technique with promising results with minimal complications.

Megaprosthesis in distal femur nonunions in elderly patients-experience from twenty four cases.

PURPOSE OF THE STUDY: To evaluate the outcomes and complications using cemented megaprosthesis in elderly patients with distal femur nonunions (DFN). MATERIALS AND METHODS: Between 2012 and 2016, 24 patients of DFN with an average age of 71.8 years (66-83) and an average 1.9(1-3) prior surgery was managed with distal femur replacement using cemented modular endoprosthesis. Outcomes were analysed on the following criteria: implant status, complications, knee range of motion, Knee Society Score (KSS) and Musculoskeletal Tumor Society (MSTS) score. RESULTS: All patients were extremely satisfied with their outcomes. At an average 22.1 months (10-43) follow-up, patients had an average 69.5° (40°-110°) knee flexion, an average KSS of 75.7 (63-88) and an average MSTS score of 19.3 (17-25). Four patients died at an average 21.3 months after surgery due to causes unrelated to the fracture. One patient (4.1%) had implant-related complication; deep infection which required debridement and intravenous antibiotics. There were no late amputations or peri-operative deaths and no patient had aseptic loosening of components. CONCLUSION: By permitting immediate full weight-bearing ambulation and with most patients returning to an acceptable functional status, cemented megaprosthesis is a viable and useful single-stage management option in elderly patients with DFN.

Marginal impaction in complex posterior wall acetabular fractures: role of allograft and mid-term results.

OBJECTIVE: To evaluate the functional and radiological outcome of complex posterior wall acetabular fractures with marginal impaction treated with cancellous allograft and internal fixation. METHODS: A total of 16 patients with marginal impaction on pre-operative CT scan, who underwent internal fixation and allograft were analysed. Mean follow-up was 28 months (range 24-42). The mean age was 46.5 years (range 22-71). Out of 16 patients, 8 were AO A1.2- and 8 were AO A1.3-type fractures. Functional evaluation was performed using modified Merle d'Aubigné and Postel scores and radiological evaluation by Matta's criteria for quality of initial reduction and final outcome. RESULTS: The quality of reduction was anatomical in 12 patients (75%) and imperfect in 4 patients (25%). The radiological outcome at final follow-up was excellent in 9 (56.25%), good in 5 (31.25%) and fair in 2 patients (12.5%). None of the patients had a secondary loss of reduction at final follow-up. Functional outcome was excellent in 2 (12.5%), good in 8 (50%) and fair in 6 patients (37.5%). CONCLUSION: The use of cancellous allograft to fill the bone void provides good mechanical stability without any secondary loss of reduction. This surgical technique seems to be effective and safe in treating comminuted posterior wall fractures with marginal impaction without any donor site complications and other disadvantages of synthetic bone graft materials.

Impaction Bone Grafting and Valgus Osteotomy: A Technical Trick for the Treatment of Femoral Neck Nonunions.

Femoral neck nonunions in young adults is among the most challenging problems to treat. This is due to their inherent problems, such as neck resorption, increase in fracture gap, sclerosis of fracture margins, and avascular necrosis. Hip salvage in these cases, although challenging, is recommended in the Asian subcontinent where social and religious activities require squatting and sitting cross-legged. Muscle pedicle grafts and other vascularized bone grafting techniques are preferred treatment options, but they are technically demanding and require advanced microsurgical skills. Valgus osteotomy, although successful in certain cases, has a high failure rate in patients with poor bone stock. We present a simple technique of valgus subtrochanteric osteotomy, impaction bone grafting, and stabilization with a sliding hip screw. Here, we describe in detail about the surgical technique and present the clinical outcomes in 44 patients, with a mean follow-up of 3.4 years and a union rate of 95.5%.

A surgical algorithm for the management of recalcitrant distal femur nonunions based on distal femoral bone stock, fracture alignment, medial void, and stability of fixation.

BACKGROUND: Recalcitrant distal femur nonunions (RDFN) are a challenge in management due to factors including poor bone stock, multiple surgeries, metaphyseal bone loss, and joint contractures. There are no specific guidelines in the management of cases of RDFN. Based on our experience, we devised an algorithm and we present the results of 62 cases of RDFN managed following it. MATERIALS AND METHODS: Our algorithm was formulated after analyzing 34 cases of RDFN and it involved four factors which were hypothesized to influence outcomes namely: distal femoral bone stock, extent of medial void, alignment of the fracture, and stability of fixation. Each factor was addressed specifically to achieve a good outcome. Between 2012 and 2015, 62 patients with RDFN at a mean age of 47.4 years (26-73) and 2.3 prior surgeries (2-6) were managed following the algorithm. INTERVENTION: 58 patients required revision osteosynthesis to improve alignment and achieve a stable fixation. 4 elderly patients with poor bone stock were managed with arthroplasty. Extent of medial void was found to significantly influence surgical decision making. Five patients without medial void required only cancellous autograft bone grafting, 47 patients with < 2 cm void were treated with an allograft fibular strut inserted in the metaphysis and 6 patients with a void > 2 cm were managed with medial plating. OUTCOMES AND RESULTS: 57 patients treated with osteosynthesis achieved union at an average of 7.4 months (6-11) and the 4 patients managed with arthroplasty also had a favourable outcome. One patient who was managed with revision osteosynthesis had a nonunion with an implant failure and needed an arthroplasty procedure. The average LEFS (lower extremity functional score) of all our patients was 67 (51-76) at an average follow-up of 18.2 months (12-33). CONCLUSION: Our stepwise surgical algorithm would help surgeons to identify the factors that need to be addressed and guide them towards the interventions that are necessary to achieve a successful outcome while managing cases of RDFN.

Radiation Exposure to the Surgeon, Surgical Assistant, and Scrub Nurse During Closed Intramedullary Nailing of Long Bones-Does It Vary Depending on the Experience of the Surgeon?

OBJECTIVES: To assess radiation exposure (RE) to the surgical team and fluoroscopy time (FT) during closed nailing of long bone fractures performed under fluoroscopic guidance with regard to surgeon's experience. DESIGN: Prospective observational study. SETTING: Level-1 trauma center. PARTICIPANTS: Surgical team, comprising a surgeon, a surgical assistant, and a scrub nurse, for closed nailing procedures performed in 202 consecutive closed tibial and femoral diaphyseal fractures. INTERVENTION: Dosimeter provided to each member of surgical team. Surgeon experience level (trainee, senior registrar, and consultant). MAIN OUTCOME MEASUREMENTS: RE (microsieverts) to the surgical team and FT (minutes) were recorded from the dosimeter and fluoroscopic unit, respectively, and correlated with surgeon's experience. RESULTS: In tibial nailing, mean RE (in µSv) per procedure to surgeon, surgical assistant, and scrub nurse was 15.2, 9.2, and 2.0 for trainees, 14.5, 8.1, and 1.6 for senior registrars, and 13.6, 7.4, and 1.5 for consultants, respectively. In femoral nailing, mean RE per procedure to surgeon, surgical assistant, and scrub nurse was 181.6, 113.6, and 37.1 for trainees, 110.1, 66.7, and 20.4 for senior registrars, and 79.9, 30.9, and 12.5 for consultants, respectively. RE to the surgeon was highest followed by surgical assistant and scrub nurse irrespective of operating surgeon's experience in both tibial and femoral nailing (P < 0.001). In tibial nailing, there was a significant difference in FT only for the stage of guide wire passage (P = 0.041), whereas in femoral nailing, total FT (P < 0.001), nail entry verification (P = 0.02), guide wire passage (P = 0.013), nail introduction (P = 0.006), and distal locking (P < 0.001) showed a significant difference. CONCLUSIONS: RE was maximum for operating surgeon and least for scrub nurse irrespective of operating surgeon's experience in both femoral and tibial nailing. FT and RE to the surgical team decreased with increasing experience of the surgeon in femoral nailing. LEVEL OF EVIDENCE: Prognostic Level II.

Modified Capanna's Technique (Vascularized Free Fibula Combined with Allograft) as a Single-Stage Procedure in Post-traumatic Long-Segment Defects of the Lower End of the Femur: Outcome Analysis of a Series of 19 Patients with an Average Gap of 14 cm.

Objectives Salvage and reconstruction of posttraumatic defects of the long bone are complex due to the multiple procedures involved and increased chances of poor outcomes. We present the outcomes of the modified Capanna's technique-a reliable single-stage procedure of combining allograft and free vascularized fibular graft-in treating large posttraumatic bone defects in the distal third of the femur. Study Design This is a retrospective analysis. Materials and Methods Between April 2012 and September 2016, 19 patients with an average age of 33.8 years (range: 18-49 years) and an average defect of 14.5 cm (range: 9.5-20 cm) in the distal femur were managed by the modified Capanna's technique. Bone union time and functional outcome using lower extremity functional score (LEFS) after union were noted. Outcomes and Results Eighteen grafts went onto achieve bony union at an average of 6.6 months (range: 5-9), with an average knee flexion of 80 degrees (range: 45-110 degrees) and an average LEFS of 63 (range: 46-72). One patient had a nonunion with graft resorption at 8 months following persistent infection and was revised with debridement and augmenting the vascularized fibula from the other leg which went on to achieve union. Three patients had superficial infection, and three patients had delayed union. Conclusion The modified Capanna's technique provided increased biology and enhanced structural stability and therefore is a good single-stage procedure in the reconstruction of posttraumatic long-segment defects of the distal femur. Level of Evidence Level 4. Level of Clinical Care Level I tertiary trauma center.

Successful reconstruction of a post-traumatic defect of 16 cm of the distal femur by modified Capanna's technique (vascularised free fibula combined with allograft) - A case report and technical note.

Reconstruction of large defects following trauma in the distal femur are a surgical challenge. These cases usually require multiple procedures and are associated with poor functional outcomes. We managed a post-traumatic distal femur defect of 16 cm using the modified Capanna's technique - combination of a vascularised free fibula and an allograft - and achieved a successful union at 6 months and also a good functional outcome with knee flexion of 100°. The patient received a vascularised free fibula which was pegged into an allograft which was sculptured to bridge the defect. The construct was fixed with a locking compression plate on the lateral side. With the allograft providing structural stability and the vascularised free fibula enhancing biology, our technique which involves the expertise of an orthopaedic surgeon and a plastic surgeon is a useful single stage procedure to manage large post-traumatic bone defects.

Ipsilateral Acetabular Fracture with Displaced Femoral Head and Femoral Shaft Fracture: A Complex Floating Hip Injury.

Floating hip injuries involving the acetabulum, femoral head, and the femoral shaft are a very rare presentation. A complex floating hip injury comprising of an ipsilateral acetabular fracture associated with a displaced femoral head fracture and a femoral shaft fracture following a high-velocity road traffic accident presented to us where all the fractures were addressed with internal fixation during the primary surgery. Postoperatively, the patient suffered a dislocation of the femoral head which eventually went on to avascular necrosis at 5 months from the initial presentation. Then, the patient underwent a total hip replacement with an acetabular reconstruction following which he went on to have a good functional outcome. Our experience in dealing with such a complex case shows that it is difficult to set a protocol for such injuries and they need to be addressed on a case-to-case basis depending on the complexity of the injury.

Management of resistant distal femur non-unions with allograft strut and autografts combined with osteosynthesis in a series of 22 patients.

INTRODUCTION AND PURPOSE: Challenges to the surgeon in managing cases of resistant non-union of the distal femur include poor bone stock, disuse osteopenia and joint contractures. Procedures varying from simple bone grafting to megaprosthesis revision have been described. We successfully managed such cases using our technique of combining cortical allograft struts to augment the defect in the femoral condyle coupled with autogenous iliac crest bone grafting and locking plate osteosynthesis. MATERIALS AND METHODS: Between April 2012 and May 2014, 22 patients who presented with resistant nonunions of the distal femur following initial surgery were managed using this technique. Cortical allograft struts were taken from the tissue bank of our institution. All patients were followed up post operatively and their time to union was noted. Functional outcome was calculated using LEFS (Lower extremity functional score). The average follow up of all our patients was 24 months. RESULTS: All patients went on to achieve complete bony union. The average union time was 6.2 months (5 to 8 months). One patient who was a diabetic had superficial infection post operatively which was treated successfully with IV antibiotics. Average knee flexion was 110 degrees (80 to 130 degrees). The mean LEFS score was 72 (59 to 79). CONCLUSION: Combing a locking plate fixation with the bone grafting technique of using an allograft strut to support the metaphyseal medial bone defect and autografts gives a good union and a good functional outcome in the management of resistant non-unions of the distal femur by enhancing the biology and providing a good structural support to the distal femur.

Successful reimplantation of extruded long bone segments in open fractures of lower limb--a report of 3 cases.

Extruded bone segments are rare complication of high energy open fractures. Routinely these fractures are treated by debridement followed by bone loss management in the form of either bone transport or free fibula transfer. There are very few reports in the literature about reimplantation of extruded segments of bone and there are no clear guidelines regarding timing of reimplantation, bone stabilisation and sterilisation techniques. Reimplantation of extruded bone is a risky procedure due to high chances of infection which determines the final outcome and can result in secondary amputations. We present two cases of successful reimplantation of extruded diaphyseal segment of femur and one case of reimplantation of extruded segment of tibia.
