Investigators of this study found no statistically significant difference in the rates of heterotopic ossification at 12-month follow-up between patients with ankylosing spondylitis in Taiwan who received postoperative radiation as a prophylaxis and those who did not receive prophylactic treatment.

“This study suggests that postoperative radiation may not be necessary in Asian patients,” the researchers wrote in their study.

They retrospectively reviewed 129 hips from 91 patients with ankylosing spondylitis who underwent primary total hip arthroplasty (THA).
