Abstract
Os acetabuli is thought to be the result of an unfused ossification center or an acetabular rim fracture in the setting of femoral-sided femoroacetabular impingement syndrome. Historically, patients with symptomatic hips have been treated with resection alone; however, in patients with large bone fragments or with reduced acetabular coverage prior to surgical intervention, iatrogenic dysplasia and structural instability may develop after resection. Therefore, for patients with an acetabular os, labral tearing, and cam-type femoroacetabular impingement, internal fixation of the os acetabuli, femoral osteochondroplasty, and labral repair have been described. We propose a “suture-on-screw” arthroscopic technique to simultaneously address both the labral tear and os acetabuli, thereby reducing the number of suture anchors required for labral fixation, leading to an efficient and cost-effective approach for the treatment of these patients.
