Autogenous bone grafting has been used to reconstruct acetabulum in dysplastic hips during primary Total Hip Arthroplasty (THA). We experienced 5 joints in 5 patients (1 male and 4 females) and examined the results of cases where more than 3 years have passed after THA combined with an autogenous bone graft. The mean age at the time of surgery was 63.8 years. Clinical evaluation by JOA score and radiographic evaluation were carried out. JOA score improved from the preoperative mean of 34.4 points to the postoperative mean of 86.6 points. Bone fusion was established in all the bone grafts and neither migration of the cup nor crush of the bone grafts were found. Bone resorption was observed in some bone grafts but no clinical problems were raised.
Our study indicates that acetabular bone graft is useful for obtaining the stability of the cup.
