It has been clinically believed that the stabilizing mechanism of the Latarjet procedure is the sling effect. Biomechanical studies have demonstrated that there are 3 stabilizing mechanisms of the Latarjet procedure, the main one being the sling effect produced by the subscapularis and conjoint tendons. The other 2 mechanisms are the suturing of the capsular flap at the end-range arm position and reconstruction of the glenoid concavity at the mid-range arm position. All 3 stabilizing mechanisms function at both the mid- and end-range arm positions. After the Latarjet procedure, the shoulder even with a large glenoid defect can have stability increased by 14% compared to the normal shoulder. The acceptable clinical outcomes of the Latarjet procedure are supported by these 3 stabilizing mechanisms.
