DESTRUCTIVE ARTHROPATHY OF THE HIP AFTER SURGICAL REMOVAL OF AN INTRACAPSULAR OSTEOID OSTEOMA OF THE FEMORAL-NECK

A case of destructive arthropathy of the hip with onset two years afte r surgical removal of an intracapsular osteoid osteoma of the femoral neck is reported. Coincidental occurrence in the same joint of an oste oid osteoma and a destructive arthropathy of unknown etiology cannot b e ruled out. However, another hypothesis which deserves discussion is that self-perpetuating synovitis was triggered by the release of media tors of inflammation due to presence of the osteoid osteoma.
