title: Synovial osteochondromatosis of the hip with femoroacetabular impingement and osteoarthritis: a case report.
abstract: Synovial osteochondromatosis is a rare, benign condition characterised by synovial metaplasia and the formation of cartilaginous and osteocartilaginous bodies in the capsule. We report one such case in a 30-year-old woman with synovial osteochondromatosis of the hip and progressive osteoarthritis caused by femoroacetabular impingement with joint-space narrowing. She underwent surgical removal of 32 loose bodies and osteochondroplasty. A coronal osteophyte at the junction of the femoral head and neck was also excised. At 2-year follow-up, her Harris Hip Score had improved from 62 to 90.
