The Latarjet coracoid transfer has been described as creating a triple blocking effect due to the function of the conjoint sling, bony augmentation, and CA ligament support to the capsule. The Latarjet procedure is used for recurrent anterior instability, especially in revision cases or when there is significant anterior glenoid bone loss. The coracoid is transferred through a split in the subscapularis and fixed to the anterior face of the glenoid. One of the most common indications is glenoid bone deficiency (which is defined as 20 -30 % glenoid bone loss) which has a high failure rate when addressed with a soft tissue or capsular procedure only. Glenoid bony deficiency should be addressed with a bony procedure. In a biomechanical study by Wellmann et al, it was reported that the Latarjet procedure outperformed the contoured bone graft in reducing translation in anteroinferior glenoid bone defects. They found the Latarjet procedure is especially effective at 60 degrees of glenohumeral abduction.
