Description
Summary:To summarize retrospectively the clinical technology of repairing osteonecrosis of femoral head (ONFH) by free vascularized fibular grafting (FVFG), and the value of modified instruments in operation. Between March 2011 and January 2013, 35 patients with ONFH (47 hips) who underwent FVFG with modified instruments. There were 24 males (32 hips) and 11 females (15 hips), aged 34 years on average (range, 22-43 years). The unilateral hip was involved in 23 cases and the bilateral hips in 12 cases. The disease duration ranged from 5 to 9 months (mean, 7 months). Based on etiology, 25 hips were classified as alcohol ONFH, 12 hips as corticosteroids ONFH, 3 hips as trauma ONFH, and 7 hips as idiopathic ONFH. According to the Association Research Circulation Osseous(ARCO) stage, 3 hips were rated as stage I, 39 hips as stage II, and 5 hips as stage III on the X-ray films. The preoperative Harris score was 58.2±6.1. The time to get fibula was 15-35 minutes (mean, 25 minutes). The operation time was 90-200 minutes (mea
