Incidence of Heterotopic Ossification in Direct Anterior Approach to Total Hip Arthroplasty with use of Aspirin as Thromboembolic Prophylaxis.

Our analysis aimed to quantify the incidence of H.O. with consistency in surgical approach and post-operative protocol.

Our retrospective analysis identified H.O. at rates similar to previous studies in DAA.
