Changjun C, et al. - This study was undertaken to ascertain 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. Researchers recruited a total of 42 patients at early osteonecrosis of the femoral head (ONFH) in this study. They recorded visual analog scale (VAS) pain scores, range of hip motion (ROM), and Harris hip score (HHS) to evaluate the clinical outcome; Western Ontario McMaster Osteoarthritis index (WOMAC) scores and Short Form 36 health survey (SF-36) were performed to assess the living quality; X-ray film or magnetic resonance imaging (MRI) was applied to investigate radiographic progression; survivorship was defined as patients did not undergo the total hip arthroplasty (THA) or fusion at the last follow-up. Patients with early ONFH, results indicates that modified non-vascularized allogeneic fibula Grafting combined with core decompression and bone grafting could enhance the clinical outcomes and improve the quality of life.
