Abstract: Heterotopic ossification (HO) is a common finding after total hip arthroplasty (THA), and may cause diminished hip range of motion and an antalgic gait. Although the etiology remains unclear, two theories currently prevail. In this article, the incidence, etiology, risk factors, and classifications of HO are discussed. Effective prophylactic treatments including radiation and anti-inflammatory medications are detailed. Once HO is present, the value of these treatments are doubtful and surgical excision may be required after bony maturity. With increasing THA projected as the population ages, the need for safe, effective, and inexpensive prophylaxis may be required.
