Os acetabuli—a new arthroscopic treatment option for the acetabular rim fracture

Abstract

Abstract Os acetabuli (Os) or acetabular rimfractures are often seen in femoroacetabular impingement patients and can result in groin pain. When seen in symptomatic patients, the question is whether to remove them or to fixate the loose fragment to the acetabular rim. This depends on acetabular coverage and the extent of the Os. If removal of the Os might lead to hip dysplasia and instability, fixation of the Os should be the goal. This technical article describes the author's technique in fixating the Os with a suture-bridge technique.
