Arthroscopic Glenoid Bone Grafting With Soft Fixation for Recurrent Anterior Shoulder Dislocation

Glenoid bone defect is a common structural deficiency in cases of recurrent anterior shoulder dislocation. Glenoid bone grafting is an effective method to address glenoid defect and promote labrum regeneration. In most previous reports, firm fixation of the bone grafts was conducted, but with obvious inconvenience. Thus, we introduce a special glenoid bone-grafting technique in which the bone fragments are placed to the anterior side of the glenoid through the rotator interval, with 1 inferior graft free of fixation and 1 superior graft fixed to the glenoid by suture suspension. This technique is indicated in patients with recurrent anterior shoulder dislocation with glenoid defect or needing osseous stimulation for labrum regeneration. The critical point of this technique is the proper use of special glenoid bone grafting instruments. We believe this technique will provide a special choice in the treatment of recurrent anterior shoulder dislocation.
