An Algorithmic Approach to the Management of Shoulder Instability.

The recurrence of anterior shoulder instability can be as high as 86.7% in high-risk patients who are treated nonoperatively after their first incident of instability. CT and MR arthrography are necessary for preoperative imaging and assessment of glenoid bone loss. Patient expectations in conjunction with appropriate preoperative imaging are critical for surgical planning. Arthroscopic shoulder stabilization is often sufficient in most cases where glenoid bone loss is minimal, with recurrent dislocation rates close to 4% in the literature. Open stabilization procedures are generally indicated in patients with greater than 20% glenoid bone loss.
