Due to increased number of revisions in total hip replacements, prolonged surgery time and extensive surgical approaches heterotopic periarticular ossification is observed more frequently. A series of 790 hips operated between 1987 and 1996 has been reviewed. Type of the surgery, bone graft use, surgical approach, radiological appearance and pain around the operated hip during first 6 month after surgery were taken into consideration. In the increased risk group heterotopic ossification occurred in 52.2%, in others in 6.4% if NSAID were not prescribed. Prophylactics decreased heterotopic ossification three-fold (16.7%) in the high risk group.
