Bone nonunion and avascular osteonecrosis of the femoral head caused by the internal fixation failure for femoral neck fracture are always the complex topics in orthopedics. With regard to patients who sustain these complications, total hip arthroplasty is a proper choice for elderly patients, but is not acceptable by young patients. We report nine patients with the failure of internal fixation for femoral neck fracture who were treated with free vascularized fibular grafting and internal fixation with cannulated screw from November 2001 to October 2003. All of them achieved good results.展开更多

All patients have ben followed up for 2 to 11 years. Excellent and good rate of operative results was 86. 6%. A long observation indicated that this procedure was superior to the other operations for the osteonecrosis of femoral head. Successful interim and final operative results can warrant its continued use in management of this kind of patients.展开更多

For young patients, multidisciplinary treatment and limb salvage arerecommended, and surgical plans considering the growth potential and boneactivity after tumor resection are essential.CASE SUMMARYAn 11-year-old Asian boy had a 1-mo history of a right-sided limping gait.Imaging revealed a proximal tumor with bone destruction and physealinvolvement over the right femoral neck. He was diagnosed with stage IV(T1N0M1aG3) Ewing’s sarcoma with bilateral lung metastases. Neoadjuvantchemotherapy decreased the tumor size and confined it to the metaphysealregion. The patient underwent four stages of surgery: wide tumor excision plusreconstruction with vascular fibular bone graft plus internal fixation;repeat openreduction and internal fixation;femoral lengthening with orthosis after physealmaturity;and orthosis removal and bone elongation (approximately 6 cm).Following surgery, he could walk without discomfort and had almost equal-sizedbilateral femoral heads, indicating physis preservation. The surgery wassuccessful, and normal femoral head growth was achieved after completeremission. The patient was able to resume normal activities with equal length ofthe bilateral lower limbs.CONCLUSIONTumor treatment and reconstruction following resection are important in skeletally immature patients with Ewing’s sarcoma to improve quality of life.展开更多
