Abstract
Heterotopic ossification (HO) was investigated in 126 primary total hip arthroplasties (THAs), and several risk factors which had already been reported to be associated with HO were evaluated.
HO was observed in 41 cases (32.5%) . Some of the risk factors, being male, and having osteoarthritis, hyperostosis, or postoperative dislocation following THA were confirmed in this study. There was, however, no statistical significance between the HO group and the non-HO group with respect to age at THA, serum alkaline phosphatase, bleeding volume or operating time.
