No benefits with computer assistance in triple pelvic osteotomy.
We evaluated computer-assisted surgery (CAS) used for 21 triple pelvic osteotomies on 20 patients with symptomatic acetabular dysplasia and compared the intraoperative and immediate postoperative data with those of 32 patients who underwent 40 pelvic osteotomies without CAS. The use of the CAS system was abandoned during 9/21 operations mostly because of technical and CT data failure. The peroperative blood loss and duration of surgery were greater, while neurovascular damage occurred less often in the CAS group. We found that the CAS system for pelvic osteotomy was not better than conventional methods.
