Lateral Decubitus All-Arthroscopic Latarjet Procedure for Treatment of Shoulder Instability.

Shoulder instability can be a challenging condition to treat when it becomes refractory to soft-tissue procedures or when bone loss exceeds 25% to 27% of the glenoid. The Bristow-Latarjet procedure has been developed and popularized to deal with these concerns. Traditionally, the procedure has been performed as an open approach; however, this has been recently supplanted by novel arthroscopic techniques. We present a technique for the procedure performed with the patient in a semi-lateral decubitus position that assists with optimal graft placement on the native glenoid. We use the cannulated Bristow-Latarjet Instability Shoulder System (DePuy Mitek, Raynham, MA). After a diagnostic arthroscopic evaluation, we use multiple arthroscopic anterior portals to debride the rim of the glenoid. The coracoid is prepared and taken down arthroscopically, and the cannulated guide is attached and advanced through an arthroscopically created subscapularis split. With the shoulder held in a reduced position, we are then able to drill and anchor the graft to the native glenoid. The patient is able to begin gentle range-of-motion exercises immediately postoperatively.
