Abstract

We report a case of rapidly destructive arthrosis of hip joint (RDA) associated with a subchondral insufficiency fracture (SIF) in a 77-year-old female patient. She complained of left hip joint pain which became progressively worse. Findings on radiographs obtained shortly after the onset of hip pain were unremarkable except for osteopenia. However, within 9 months after onset of pain, joint space narrowing rapidly progressed with collapse. She was diagnosed clinically as RDA related to osteonecrosis. She was treated by total hip replacement. The evidence of SIF was confirmed histologically by the presence of a unique granulomatous lesion in the marrow space, which consisted of amorphous debris and fragmented bone surrounded by giant cells. There was no evidence of antecedent osteonecrosis. Osteopenia and overweight were considered as predisposing factors of SIF and rapid joint destruction in this case.
