Egypt had professional doctors as early as the old kingdom 5,000 years ago. There were also specialists in different branches of medicine. Homer (ca. 800 BC) remarked in the Odyssey: "In Egypt, the men are more skilled inmedicine than any of human kind". Hippocrates, Herophilos, Erasistratus and later Galen studied at the temple of Amenhotep, and acknowledged the contribution of ancient Egyptian medicine to Greek medicine [1].

Twenty-six patients with failed dynamic hip screw fixation of intertrochanteric fractures were included in this study. The mean age of the patients was 61 years (range, 38—84 years). Average limb shortening was 2.4 cm; 18 patients were treated with revision internal fixation and eight patients with prosthetic replacement. The decision depended on the physiological age of the patient, quality of bone, and condition of the femoral head and the acetabulum. The revision internal fixation group included DHS reinsertion in eight patients, valgus osteotomy and revision DHS fixation in six, while four patients were treated by valgus osteotomy and insertion of single-angled 1308 plate. The prosthetic replacement group included cemented Thompson endoprothesis in five patients and cemented total hip arthroplasty in three. The mean follow-up period was 31 months (range, 15—72 months). All patients of revision internal fixation group achieved fracture healing without bone grafting. Time to union averaged 17 weeks. Average gain in length was 2 cm Avascular necrosis of the femoral head occurred in one patient. Six patients of the prosthetic replacement group achieved good functional outcome and pain-free gait. The remaining two had unsatisfactory result.

Introduction: We report a case of non-union with severe shortening of the femur following diaphysectomy for chronic osteomyelitis. Case Presentation: A boy, aged 16 years presented with a dangling and excessively short left lower limb. He was using an elbow crutch in his right hand to help him walk. He had a history of diaphysectomy for chronic osteomyelitis at the age of 9. Examination revealed a freely mobile non-union of the left femur. The femur was the seat of an 18 cm shortening and a 4 cm defect at the non-union site; the knee joint was ankylosed in extension. The tibia and fibula were 10 cm short. Considering the extensive shortening in the femur and tibia in addition to osteoporosis, he was treated in two stages. In stage I, the femoral non-union was treated by open reduction, internal fixation and iliac bone grafting. The patient was then allowed to walk with full weight bearing in an extension brace for 7 months. In Stage II, equalization of leg length discrepancy (LLD) was achieved by simultaneous distraction of the femur and tibia by unilateral frames. At the 6 month follow- up, he was fully weight bearing without any walking aid, with a heel lift to compensate the 1.5 cm shortening. Three years later he reported that he was satisfied with the result of treatment and was leading a normal life as a university student. Conclusions: Two-stage treatment succeeded to restore about 20 cm of the femoral shortening in a severely osteoporotic bone. It has also succeeded in reducing the treatment time of the external fixator.

Non-union of femoral neck fractures may occur due to mechanical and biological factors. Valgus intertrochanteric osteotomy (VITO) alters hip biomechanics and enhances fracture union. The double-angled 120° plate is usually used for internal fixation of the osteotomy. It allows the osteotomy to heal with medialisation and verticalisation of the femoral shaft. This deformity causes medial ligament strain of the knee joint, genu valgum and ultimately osteoarthritis. This work presents our experience in treating vertical fractures and non-unions of the femoral neck by VITO and fixation by a single-angled 130º plate. Thirty-six patients presented with 19 recent vertical femoral neck fractures, and 17 non-unions were included. They were 26 men and ten women, and their ages averaged 37 years. Preoperative planning and VITO technique are described. Union was achieved in 35 patients (97%), and one recent fracture failed to unite (3%). Time to fracture union averaged four months in recent fractures and eight months in un-united fractures. All patients with united fractures had an almost normal configuration of the upper femur. Avascular necrosis of the femoral head was reported in five patients. Twentytwo patients (61%) were pain free, nine (25%) had hip pain on lengthy walks and the remaining five (14%) had persistent pain. Preoperative limb shortening averaged 2.5 cm, and post-operative shortening averaged 0.5 cm. We recommend VITO and fixation by a single-angled 130º plate for vertical femoral neck fractures and non-unions in relatively young adult patients.
