Surgical Technique for the Latarjet Procedure Using Non-Cannulated Screws

The Latarjet procedure is effective for patients with anterior glenohumeral instability with substantial glenoid bone loss due to its triple blocking effect.

Indications include high-risk patients with recurrent anterior glenohumeral instability with any glenoid bone loss or low-risk patients with 15% to 30% glenoid bone loss.

An incision is made lateral to the coracoid and the deltopectoral interval is established. The pectoralis minor is released medially off the coracoid and the coracoacromial (CA) ligament is released close to the acromion. The coracoid is cut with a right-angle saw and the inferior coracoid is decorticated with a burr. Two holes are pre-drilled in the coracoid. The subscapularis is split between the upper two-thirds and lower one-third with the arm in external rotation. The capsule is split vertically at the joint line and the humeral head is retracted. The anterior glenoid is decorticated with a burr, and a hole is drilled inferiorly. The depth is measured and added to the depth of the inferior bone block hole. A fully threaded 3.5-mm solid stainless steel screw is placed in the inferior hole. Care is taken to ensure that the lateral border of the bone block is flush with the articular margin. This is repeated for the superior hole. A 1.8-mm knotless suture anchor is placed between the screws. The repair stitch is passed through the capsule and loaded onto the anchor and tensioned. The CA ligament is laid over the capsule and repaired. The subscapularis split is repaired side to side and the wound is closed in layers.

High return-to-sport rates, including at the same level of play, have been observed among young competitive athletes with significant glenoid bone loss who underwent a Latarjet, with similarly favorable results in older patients. Ninety-day complication rates have been reported around 9%, 5% of which constituted graft or hardware failures.

The Latarjet procedure is an effective option for indicated patients with anterior glenohumeral instability and may be enhanced with solid screws, proper anatomic technique, and capsulolabral repair augmentation.
