Περιγραφή
The authors tried to save the hip joint by implanting a vascularized fibular graft, augmented with cancellous bone, into the curetted core of the femoral head that was affected by aseptic necrosis. Forty of 66 hips were observed for a minimum of 20 months and for as long as 66 months (average, 32 months). Clinical assessment according to the cause and severity of the disease was done using the Harris Hip Score. Twenty-eight hips (70%) were rated excellent, 7 (17.5%) were good, 2 (5%) were fair, and 3 (7.5%) failed and were replaced with an artificial joint. Clinically satisfactory results, including good and excellent, were obtained in 35 hips (87.5%). Radiographic evaluation showed improved appearance of the femoral head core in all 15 patients (37.5%) operated on at a precollapse stage of the disease. In 20 hips, the deformity of the femoral head was unchanged (50%), 2 (5%) became worse, and 3 (7.5%) failed. The number of hips with improved appearance as shown on radiographs and those in which the process was unchanged equaled the number of hips with satisfactory clinical results. These data show that the procedure can induce new bone formation that fuses with the affected subchondral bone, thus preventing the articular surface from collapse. This suggests that vascularized fibular grafting is an excellent alternative for hip salvaging when treating femoral head osteonecrosis.
