Introduction: Incidence of non-union of fracture involving the supracondylar region of femur in an elderly is increasing due to bone loss from trauma and availability of poor quality bone in geriatric population. Distal femur megaprosthesis can provide a single stage solution for resistant non-union of supracondylar femur. Case Report: We are reporting two cases of non-union of supracondylar femur with implant failure treated with distal femoral tumor megaprosthesis. We achieved excellent improvement of the Knee Society Score from 15 to 75; Knee Society Function Score from 0 to 60, good range of motion, and pain free ambulation without support at 3 months follow-up. Conclusion: Management of non-union of supracondylar femur with implant failure is challenging task. Distal femur replacement using tumor megaprosthesis is useful option for such resistant cases in achieving early ambulation and overall good functional outcome. Keywords: Non-union, distal femur fracture, megaprosthesis, supracondylar femur fracture.

Aim: Intertrochanteric fractures account for almost 50% of hip fractures.Nonunion and malunion of these fractures are relatively uncommon. This study reviews the outcome of 31 cases of intertrochanteric fracture failures. An algorithm for the management of these injuries is also proposed. Methods: 19 patients with intertrochanteric malunion and 12 patients with non-union were included in this study. Treatment of these injuries was initiated according to the algorithm proposed in this study. Treatment outcomes were evaluated by assessing union, pre and postoperative shortening and HSA (head-shaft angle). Functional outcomes were assessed by the Parker mobility scale and presence or absence of pain. Results: All the patients with intertrochanteric malunion with follow-up had united. The postoperative shortening in all patients were ⩽2.5 cms. Patients having intertrochanteric nonunion with follow-up, who underwent internal fixation had united with an acceptable Parker mobility scale score, except in 1 patient who sustained an ipsilateral distal femur fracture. The average HSA correction obtained was 21° (range 3–60°). Conclusion: The algorithm proposed in this study helps streamline the treatment according to each case scenario.It helps in planning and managing patients with intertrochanteric fracture failures.

Ewing sarcoma is a malignant bone tumor that mainly affects children, adolescents and young adults with more than 1.5 cases per million worldwide. Approximately 20-25% of patients present metastatic disease at the diagnosis, that is often resistant to intensive therapy.We present the case of a 19-year-old male with history of epilepsy who started his condition with weight loss, increased volume, pain, swelling after receiving surgical treatment due to a left distal femur fracture, showing tomographic evidence of a 50-cm tumor with multiple lung lesions, so disarticulation was performed with the Boyd technique, obtaining histopathological result of Ewing’s Sarcoma, and was subsequently sent to the medical oncology service for follow-up and adjuvant treatment with significant clinical and radiological improvement in pulmonary metastatic activity.

In these case series, we used titanium locking compression plate-distal femur (LCP-DF) plate (Synthes) 9–11 hole using less invasive stabilization system or open reduction technique. This case series aims to determine the functional scores on reverse distal femoral locking plate for subtrochanteric femur fracture. A 34-year-old male with closed subtrochanteric fracture of the right femur (Seinsheimer 2B) with Harris hip scores (HHS) of 17, 96, and 97 obtained consecutively in 0, 6, and 12 months, respectively. A 24-year-old male with closed comminuted subtrochanteric fracture of the right femur (Seinsheimer V) with HHS of 13, 93, and 97 at 0, 6, and 12 months respectively. A 39-year-old male with non-union, left subtrochanteric femur fracture (Seinsheimer 2C) yielded HHS of 38, 73, and 77 at 0, 6, and 12 months, respectively. A 35-year-old female with close subtrochanteric fracture of the right femur (Seinsheimer IIB) yielded HHS of 23, 40, and 73 at 0, 6, and 12 months, respectively. Mean initial HHS and scores at 6 and 12 months reached 22, 75, and 86, respectively.

Introduction: Managing distal femur non-union can be a struggle for any orthopedician as it brings along many perplexities which may not lead to satisfactory patient outcome. The target in these cases should be to reduce the morbidity and allow early rehabilitation of the patient and to accomplish this, megaprostheses can be a feasible option. The orthodox use of megaprostheses is in the musculo-skeletal oncologic surgeries but its use can be extended to traumatic etiologies. These can be offered as a single stage definite procedure in patients who have already undergone several previous surgeries. Here we report a series of four cases of persistent non-union of distal femur treated with megaprostheses and recommend this modality for achieving the desired goal but the indication should be meticulously selected. Hypotheses: Megaprosthesis as a definitive treatment option in persistent distal femur non-union and prevention of repeated surgical intervention. Methods: Four cases of persistent distal femur nonunion with failed osteosynthesis were selected who were initially treated with a distal femur locking plate. Results were assessed in terms of range of motion, limb length discrepancy, knee society score and osteointegration of the components. Results: The mean age of the patients at the time of DFEPR was 49 years (42-55). The mean follow up of patients was for approximately 2 years, with the longest follow up being 3.5 years for the first operated case of the series. The range of motion was from full extension to about 105 degrees of flexion with two patients having an extension lag of 10 degrees. Patients were ambulatory without support. Postoperatively, the mean knee society score was 83 (78–88) at last follow-up as compared to 29 (21-36) in the pre-operative period. No case of infection or loosening was reported. There was 1 cm of shortening in one patient in the operated limb which was compensated by giving shoe raise. Good osseointegration of the megaprosthesis was revealed on both anteroposterior and lateral radiographs. Conclusion: Although there are very limited studies on the use of megaprosthesis for traumatic cases, it can be considered as an alternative when we are left with only arthrodesis or amputation as the final option. Despite the operative challenges, there is marked improvement in pain and functional capacity as experienced by these severely limited patients, which are the hallmarks of a successful salvage. The use of distal femur mega-prosthesis is a novel acumen in cases, where bone stock at the fracture site at distal end of femur is so severely compromised that traditional revision osteosynthesis would not provide stable and durable fixation. The indications for this surgery must be rigorously selected and should only complement osteosynthesis procedures, which remain the reference treatment option.

<p class="abstract">Subtrochanteric femur fracture accounts for 25% of all hip fracture and may land up in non-union due to the inadequate reduction and fixation tech, local muscle pull over fragments, biomechanical stress in subtrochanteric region and soft tissue interposition etc., non-union are managed with various choices of implants like exchange nailing , angle blade plate , dynamic condylar screw, augmentation of previous hardware with plate and by providing biological environments at fracture site using  bone graft. Strict adherence to principles of providing stability to fracture and providing environment for bony growth gives good clinical outcome. A 52 years old male with subtrochanteric femur fracture was operated with long PFN, later presented to us after 18 months with failure of the hardware and atrophic non-union manifesting as pain during walking and limping. Patient was operated with removal of implant and exchange nailing using femur interlock nail and autologous bone grafting from iliac crest graft. 1 year follow up showed complete bony union and abundant of callus formation. Patient is currently doing all the daily activities and have no complaints at present. At 1 year follow up there is complete union at non-union site and good clinical outcome is achieved. Exchange nailing with interlock nail and autologous bone grafting for treatment of atrophic non-union of subtrochanteric femur fractures gives good clinical outcome.</p>

Introduction: Segmental bone loss in the distal femur presents a challenge for reconstruction regardless of etiology. Use of tantalum trabecular metal cones with intramedullary fixation and autologous bone graft may be used as a salvage technique in difficult situations where other options have either been exhausted or are unavailable. Case Report: Surgical planning and technique for this approach to reconstruction are described. A retrospective review of five cases with >1 year of follow-up was performed to provide radiographic and clinical outcomes. All five patients had satisfactory outcomes with clinical union and retention of implants at final follow-up (average >4 years). Conclusions: Use of tantalum metal cones for reconstruction of distal femur nonunion with segmental bone defects can be a successful technique in a complex group of patients. Keywords: Femur, bone defect, non-union, induced membrane, tantalum.

The geriatric population in general and specifically recipients of total knee arthroplasty (TKA) have increasing functional demands along with an increasing life expectancy. Certain intraoperative aspects of the index procedure, revision TKA, or the patient’s physiology (i.e.- osteoporosis, rheumatoid arthritis, neurologic disease) predispose the patient to post-operative periprosthetic distal femur fractures (PDFF). This review describes the epidemiology, classification, examination, and treatment options of PDFF. Osteoporosis and intraoperative anterior femoral cortex notching are primary patient and surgeon specific factors, respectively. The two most commonly used classification systems were described by Rorabeck and Kim and should be used to guide the surgeon’s choice of treatment.  The non-operative treatment of PDFF is rare, requires close radiographic follow up, and delayed union is common. Open reduction with internal fixation (ORIF) is best accomplished with minimally invasive techniques and distal locking screws. Retrograde, intra-medullary nail fixation is technically difficult, but provides earlier weight bearing and comparable time to union as ORIF.  Revision TKA is indicated in patients with adequate bone stock, a simple fracture pattern without ligamentous instability, and a loose or malaligned femoral component.  Allograft-prosthetic composite (APC) or distal femoral replacement (DFR) is indicated for patients presenting with a PDFF about poor or deficient bone stock.  Patients with PDFF present a challenge to the arthroplasty surgeon in regards to choice of treatment and increased morbidity and mortality post-operatively. Close follow up is required and fracture union is often delayed.
