旋髂深血管髂骨瓣移植治疗中青年股骨头缺血性坏死远期髋关节功能观察
Objective To retrospect the long dated curative effect of grafting of iliac bone flap with deep iliac circumflex vessel in treatment of femoral head ischemic necrosis.Methods 79 cases of femoral head ischemic necrosis treated by promoted Smith Petersen incision, neck of femur notch, focus cleaning decompression,grafting of iliac bone flap with deep iliac circumflex vessel and screw fixation. 13 cases treated by transplanting granular bone after decompression. Results Grafting of iliac bone flap with deep iliac circumflex vessel treatment group were followed up from 3 to 9 years,the planting bone healed 3 to 6 months averagely.Two cases suffered femoral head ischemic necrosis continuously.Other cases received good results.Transplanting granular bone after decompression group were followed up 3 to 9 years, 3 cases suffered femoral head ischemic necrosis continuously, hip joint function was limited,patients received hip replacement finally. Conclusion Place of iliac bone flap with deep iliac circumflex vessel is fixed, curative effects are credible, which can become the first choice therapy to femoral head ischemic necrosis of middle age and young people (Ficat I～ III stage).
