Abstract
We present an unusual presentation of acetabular component loosening in a
58 year-old female patient. The prosthesis type was hydroxylapatite-coated total hip
system. Initially, it was supposed to be severely wearing that resulting in thinning
of superior portion of the polyethylene. We performed revision operation for the
acetabular component and found that there was complete loosening between cup and
acetabulum and the prosthesis was 180 degrees of rotation around the central spike.
This is an interesting phenomenon and we postulated the mechanism of loosening.
