Arthroscopic Remplissage and Open Latarjet Procedure for the Treatment of Anterior Glenohumeral Instability With Severe Bipolar Bone Loss

Abstract

Bipolar bone loss in patients with anterior glenohumeral instability is challenging to treat. The goal of the treatment is to restore stability by ensuring that the humeral head remains within the glenoid vault. This can be achieved either with the combination of an arthroscopic Bankart procedure and remplissage (glenoid bone loss 25%). In cases with more severe bipolar bone loss of both the glenoid and the humeral head, the conventional approach has been to lengthen the articular arc of the glenoid and to ignore the Hill-Sachs lesion. However, it has recently been shown that this can still lead to an “off-track” situation with persistent shoulder instability from engagement of the Hill-Sachs on the anterior glenoid. In these cases, the combination of a Hill-Sachs remplissage and the Latarjet procedure can be effective in preventing persistent instability. In this technical note, the surgical technique of an arthroscopic Hill-Sachs remplissage in combination with an open Latarjet procedure is presented.
