Preoperative Irradiation for Prevention of Heterotopic Ossification Following Prosthetic Total Hip Replacement Results of a Prospective Study in 462 Hips

摘要

Background: The effectiveness of pre- or postoperative radiotherapy for prevention of heterotopic ossification (HO) following total hip replacement (THR) has already been demonstrated in the past. Thereby, in most studies using preoperative radiotherapy patients were irradiated < 6 h before surgery. The purpose of this prospective study was to analyze the effectiveness of preoperative irradiation on the evening before surgery and to identify risk factors for HO in a homogeneous collective of patients.
