Heterotopic ossification is a complication of total hip arthroplasty in 14 to 30% of patients. Significant functional impairment will occur in up to 28% of patients with ectopic bone. The high risk group includes those with preexisting heterotopic bone in either hip, those suffering from hypertrophic osteoarthritis or ankylosing spondylitis and patients who have had multiple procedures on the hip. Fifty-eight patients (67 hips) were irradiated after surgical removal of ectopic bone (53 hips) or received radiation prophylaxis of heterotopic ossification (14 hips). Ninety-five percent of patients had either no bone visible or insignificant amounts of ectopic bone visible on postoperative hip X-rays. Only 5% of patients showed significant persistence of ectopic bone. Postoperative hip function was dramatically improved compared to preoperative function in all patients treated. The importance of early commencement of irradiation is emphasized.
