[Coxitis after surgical excision of intracapsular osteoid osteoma of the femur neck].

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