Arthroscopic Technique for Reduction and Fixation of an Acetabular Rim Fracture.

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.
