Arthroscopic Technique for Reduction and Fixation of an Acetabular Rim Fracture

Abstract

Acetabular rim fractures can accompany patients with femoroacetabular impingement. Frequently, the acetabular rim fracture is excised. However, if the osseous fragment of the acetabular rim fracture is large enough to result in instability, then the acetabular rim fracture should be reduced and secured with internal fixation. The purpose of this technical note was to describe the arthroscopic technique of internal fixation of an acetabular rim fracture.

Arthroscopic Suture Fixation of Os Acetabuli With Absorbable Suture Anchors—A Double-Pulley Technique

“…Pérez et al 12 and DeFroda et al 13 reported the suture-on-screw technique for os acetabuli fixation and labral repair simultaneously. Essilfie et al 14 reported a hybrid technique to fix acetabular rim fractures and labrums with metal screws and suture anchors, respectively. This technique theoretically provides rigid fixation for os acetabuli, but it also has some drawbacks, first, it could be a technical challenge to perform an arthroscopic fixation using common instruments of routine traumatic orthopaedics.…”
