Abstract
Heterotopic ossification (HO) is a common radiographic finding and potentially serious complication after modern total hip arthroplasty. Although historically associated with the posterolateral approach, HO has been noted in 10% to 40% of patients having direct anterior or anterior-based muscle sparing approaches. The available data are uncertain whether robotic arm–assisted procedures are associated with this complication. Current prophylaxis for patients considered high risk of this complication includes postoperative, nonsteroidal, anti-inflammatory medication for several weeks or low-dose perioperative irradiation. The surgical treatment of symptomatic HO associated with severely restricted motion or ankylosis of the hip should be individualized but may include wide excision of bone, acetabular revision to prevent instability, and prophylaxis to prevent recurrence.
