Abstract

PurposeThe aim of this study was to determine mid-and-long term follow-up results of patients with early femoral head osteonecrosis who were treated by modified free vascularized fibular grafting combined with core decompression and bone grafting.MethodsForty-four patients at early ONFH were included in this study. Visual analog scale (VAS) pain scores, range of hip motion (ROM), and Harris hip score (HHS) were recorded to assess the clinical outcome; Western Ontario McMaster Osteoarthritis index (WOMAC) scores and Short Form 36 health survey (SF-36) were conducted to measure the living quality; X-ray film or magnetic resonance imaging (MRI) was used to evaluate radiographic progression; survivorship was defined as patients did not undergo the total hip arthroplasty (THA) or fusion at the last follow-up. Median follow-up was 7.4 years (6–8.2 years).ResultsThe mean VAS score, ROM, and HHS were significantly improved at the final follow-up compared with preoperative values (p < 0.001). Health assessment including WOMAC scores and SF-36 were also better than those preoperatively (p < 0.001). Seven patients progressed to Ficat III and the four patients progressed to Ficat IV with osteoarthritis. Eight patients who cannot tolerate the pain and had poor living quality underwent THA.ConclusionModified non-vascularized allogeneic fibula Grafting combined with core decompression and bone grafting could improve the clinical outcomes and enhance the quality of life for patients with early ONFH.
