摘要
Vascularized fibular grafting has been used for treatment of osteonecrosis of the femoral head and although some reports demonstrate successful short- to mid-term outcomes, long-term results are still unknown. We retrospectively reviewed 135 patients (151 hips) who underwent vascularized fibular grafting for osteonecrosis of the femoral head. One-hundred and ten patients (124 hips) were followed for a minimum 10 years (mean, 13.9 years; range, 10-23.7 years). The mean Harris hip score improved from 72 to 88. At the latest followup, we found improved or unchanged radiographs in 37 of 59 hips initially Stage II hips and 39 of 65 Stage III hips. Thirteen hips (13 patients) (10.5%) failed treatment and underwent total hip arthroplasty. The location and size of the necrotic lesion and the patient's age influenced long-term survival of the graft. Postoperative complications included clawing of the big toe in 17 patients, partial peroneal nerve palsy in two, and superficial infection in two. Subtrochanteric fracture occurred in two hips. The data suggest free vascularized fibular grafting was successful in maintaining joint function and delaying the need for joint replacement procedure. Graft survival was associated with the patient's age and size and location of the lesion but not etiology and stages of the disease. Level of Evidence: Level IV, therapeutic study. See the Guidelines for Authors for a complete description of levels of evidence.
