title: Arthroscopic bone graft procedure for anterior inferior glenohumeral instability.
abstract: There are many described surgical techniques for the treatment of recurrent anterior shoulder instability. Numerous authors have performed anterior bone block procedures with good results for the treatment of anterior shoulder instability with glenoid bone loss. The benefits of using arthroscopic procedures for surgical stabilization of the shoulder include smaller incisions with less soft-tissue dissection, better visualization of the joint, better repair accessibility, and the best possible outcome for external rotation. We describe an arthroscopic anteroinferior shoulder stabilization technique with an iliac crest tricortical bone graft and capsulolabral reconstruction. It is an all-arthroscopic technique with the advantage of not using fixation devices, such as screws, but instead using special buttons to fix the bone graft. The steps of the operation are as follows: precise placement of a specific posterior glenoid guide that allows the accurate positioning of the bone graft on the anterior glenoid neck; fixation of the graft flush with the anterior glenoid rim using specific buttons under arthroscopic control; and finally, subsequent capsular, labral, and ligament reconstruction on the glenoid rim using suture anchors and leaving the graft as an extra-articular structure.
