OBJECTIVE: To investigate the short-term clinical effect of double channel decompression and bone grafting through the greater trochanter combined with allograft fibula propping in the treatment of osteonecrosis of femoral head (ONFH). METHODS: Twenty two patients (23 hips) with osteonecrosis of the femoral head were included from November 2017 to February 2019. According to Association Research Cirulation Osseous(ARCO) staging, there were 13 hips at stageⅡgroup, aged from 20 to 48 years old with an average of(32.5±8.5)years old;10 hips at stageⅢgroup, aged from 18 to 45 years old with an average of(32.7±8.6) years old. A single approach through the greater trochanterwas used for decompression, bone grafting and fibula support. Harris scoring system was used to evaluate the function of hip joint before and after implantation, and the anteroposterior and lateral X-ray films of hip joint were taken at 3, 6, 12 and 18 months after implantation to observe and analyze the progress of femoral head necrosis and regeneration. RESULTS: All patients were followed up, and the duration ranged from 12 to 18 months with an average of (14.6±2.1) months. Harris score of stageⅡand stageⅢpatients increased from 73.2± 5.5 and 66.5±3.4 to 87.6±8.7( CONCLUSION The effect of double trochanteric decompression and bone grafting combined with fibular allograft propping in the treatment of early and middle stage avascular necrosis of the femoral head is good, especially suitable for young and middle aged patients with ARCOⅡstage avascular necrosis of the femoral head.
