title: Incidence of heterotopic ossification following total hip arthroplasty in patients with prior stroke.
abstract: This study reviewed the incidence of heterotopic ossification and the functional limitations in a cohort of consecutive patients with prior stroke who underwent primary total hip arthroplasty (THA). Thirty-one primary THAs were performed in 22 patients who had a cerebrovascular accident prior to THA. Mean follow-up 35 months. The overall incidence of heterotopic ossification was 36%, with significant Brooker class III and IV heterotopic ossification reported in 22% of patients. The data suggest that prior cerebrovascular accident may pose an increased risk of significant heterotopic ossification following primary THA. Consideration of prophylaxis in this subset of patients may be warranted.
