Heterotopic Ossification: A Challenging Complication of Total Hip Arthroplasty: Risk Factors, Diagnosis, Prophylaxis, and Treatment

Figure 1

Heterotopic ossification visible on an AP X-ray (a) and on a computed tomography scan (b) around right hip. It is a complete hip ankylosis. HO like this can completely sabotage functional outcomes of THR limiting the range of motion in all planes. This is why using right prophylaxis is so crucial (from the Department of Orthopaedics and Traumatology of the Musculoskeletal System, Infant Jesus Teaching Hospital, Medical University of Warsaw records).
