Indomethacin inhibits the recurrence of excised ectopic ossification after hip arthroplasty: A 3–4 year follow-up of 8 cases

Abstract

Eight patients were treated with indomethacin and excision of paraarticular ossification after hip arthroplasty. In 1986 we reported that after 3 months substantial ossification had recurred in only 2 patients. We now report that ossification had not progressed further at follow-up 3–4 years later. All 8 patients were painfree and the majority had good hip motion. We conclude that indomethacin permanently prevents recurrence after excision of paraarticular ossification.
