The fate of osteophytes in the superolateral region of the acetabulum after total hip arthroplasty.
Acetabular osteophytes are common during total hip arthroplasty (THA). However, the fate and role of superolateral osteophytes of the acetabulum after THA remain unclear. The present study reviewed a series of radiographic changes in the osteophytes on the superolateral region of the acetabulum in 35 hips. The mean follow-up period was 42.2months. The results revealed that the osteophytes that were not in contact with the superolateral edge of acetabular cup were gradually absorbed after THA. In contrast, the osteophytes that were in contact with the superolateral edge of the acetabular cup underwent remodeling, formed regular trabecula, were stress bearing, and eventually integrated with the acetabular cup and the original acetabular bone, and should play a role in stabilizing the acetabular cup.
