We evaluated the results of the rotational acetabular osteotomy using an allogeneic heat-treated or freeze-dired bone graft clinically and radiographically. The average age of the patients at the time of the osteotomy was thirty one years old. The average duration of follow-up was two years. We preserved the power of abduction of the hip joint without stripping procedure of gluteus medius. There are no obvious absoaption or collapsing of the grafted bone radiographically. The results of the rotational acetabular osteotomy using an allogeneic bone graft is better as compared with the rotational acetabular osteotomy using an autogenous bone graft.
We reported the utility of heat-treated or freeze-dried bone graft at the time of the rotational acetabular osteotomy.
