Efficacy of fibula fixation in the early treatment of Osteonecrosis of the femoral head and its effects on local microcirculation, articular surface collapse, joint pain and function

摘要

Objectives: The aim of this study is to investigate the efficacy of fibula fixation in the early treatment of osteonecrosisof the femoral head (ONFH). Methods: 130 patients with ONFH were selected and randomly divided into control group andobservation group. Patients in the control group received core decompression treatment, while patients in the observationgroup received fibula fixation. The local microcirculation was observed by dynamic contrast-enhanced MRI, necrotic volumewas measured using MRI, articular surface collapse by using X-ray, McGill pain questionnaire was used to understand andcompared the joint pain condition. Results: Τhe total effective rate of the observation group was significantly higher thanthat of the control group (p<0.05). Necrosis volume of observation group was significantly smaller than that of controlgroup (p<0.05). Degree of joint pain was significantly lower in observation group than in control (p<0.05). Harris scoreswere higher in observation group than in control group (p<0.05). All life scores of observation were significantly higher thanthose of control group (p<0.05). Conclusion: fibula fixation seems to be not superior to core decompression n preventingarticular surface collapse, but it can effectively relieve the joint pain in patients with early ONFH.
