Heterotopic ossification (HO) is a frequent complication of hip surgery. In this study the incidence of HO is analyzed in high risk patients who received radiation therapy (RT) after total hip replacement (THA) with regular and miniposterolateral hip approach. Two hundred and thirty five high risk patients received a single dose of 700 rad after THA. The incidence of HO was 15.7%. The incidence of HO in the high risk subgroup with the miniincision was lower (5.7%) but not significantly different (P=0.230). Hypertrophic osteoarthritis was demonstrated to be the consistent predisposing factor for HO formation (P=0.005)
