title: Extracapsular wide resection of a femoral neck osteosarcoma and its reconstruction using a pasteurized autograft-prosthesis composite: A case report.
abstract: The requirement for an extracapsular resection is indicated for malignant bone tumors that have disseminated intracapsularly. Extracapsular resections are often performed for malignant tumors arising from the knee joint, but there are relatively few studies that have described an extracapsular resection of a tumor arising from the hip joint. The present study describes a case of extracapsular wide resection of the hip joint using rotational acetabular osteotomy. The patient was a 17-year-old female and the diagnosis was an osteoblastic osteosarcoma with a pathological fracture of the femoral neck. The joint was reconstructed using an allograft-implant composite graft and total hip arthroplasty. Although the patient presented a slight Trendelenburg gait, no recurrence or metastases were identified during a follow-up period of 3 years. The clinical features and surgical procedure of the case are described.
