ABSTRACT

Objective To retrospect and probe the clinical applied value and the results of iliac bone with the deep circumflex iliac vessel transplantation for the treatment of avascular necrosis of femoral head.Methods With a composite procedure including synovectomy,fenestration,curettage and vascularized iliac bone graft with pedicle of the ipsilateral deep circumflex iliac vessels.Results Follow-up period average 2 years 8 months(range:for 6 month-5 years) and all patients were roentgenographied.According to new grading treatment system four items and six grades for avascular necrosis of femoral head was evaluated.Excellent and good rate was 84 4%.Post-operative radiological assessment demonstrated that there was no incidence of deterioration or further collapse of the femoral head and certain extent of re-sphering and re-surfacing of the head was observed in all of the collapsed heads.Conclusions The results of this study suggest that the technique is suitable for the treatment of avascular necrosis of femoral head of the stage Ⅰ Ⅱ Ⅲ and younger patients of late stage.
