‍Shoulders that dislocate following traumatic injuries need to have the damaged and torn structures repaired.  Many patients have only cartilage torn however, some patients have segments of bone broken or worn away from the front of the shoulder.  If this is the case then the shoulder is frequently highly unstable.  If a large segment of bone is missing from the front of the shoulder then it needs to be reconstructed.  The best way to do this is with a latarjet procedure.  In a latarjet procedure the coracoid process is transferred to the front of the shoulder joint to the neck of the scapula. This procedure involves transferring the coracoid process from the front of the shoulder to the anterior margin of the glenoid. To allow the bone block to be placed on the front of the shoulder joint the subscapularis muscle which runs across the front of the shoulder must be split to allow the bone block to passed through and attached to the glenoid. There is a tendon which attaches to the tip of the coracoid process of bone.  This tendon is called the conjoint tendon and is formed largely by the biceps muscle.  This tendon is left attached and because the bone block is passed through the split in the subscapularis muscle the tendon remains passing through this split.    Biomechanical studies have shown that approximately 60% of the stabilising effect of the operation on the shoulder is due to sling effect of this tendon passing through subscapularis.  The bone block contributes approximately 20% to the stability of the reconstructed shoulder and the labral repair contributes a further 20%. The Latarjet procedure has become an important surgical procedure for treating shoulder instability because of its ability to deal with bony defects of the glenoid. The approach to shoulder instability is to perform an arthroscopic bankart repair in those patients in whom there is no bone defect and only a cartilaginous labral defect.  In patients whose shoulders have a bony defect I will normally recommend an arthroscopic latarjet procedure. The advantage of the latarjet. is that the bone block can be positioned with Following latarjet surgery you will need to wear a sling for the first 6 weeks post operatively to ensure that the bone block unites to the anterior glenoid. A Physiotherapist will see and give you some exercises to do.in the first 6 weeks after your operation rest is more important than exercise. A CT scan will need to be performed after 6 weeks post operatively. I will review the CT with you at your 6 week post operative appointment to confirm bone healing has occurred.  If the bone block has healed then your rehabilitation programme and return to work and sport plans can be upgraded and you will be able to look at going back to work and returning to sport.
