Pathologic Fracture in a Subchondral Cystic Lesion at the Superior Acetabulum / 대한정형외과학회잡지

Subchondral cyst is a benign cystic lesion, and it is often found in patients with rheumatoid arthritis or osteoarthritis. However, its occurrence in those joints without preexisted disease is rare. Furthermore, there has been no report in the medical literature regarding pathologic fracture in the bony plate of a subchondral cyst at the superior acetabulum. We report here on a case of the 44-year-old woman for whom a pathologic fracture was found in the bony plate of a subchondral cyst at the superior acetabulum.
