Abstract

The stability of the glenohumeral joint is determined by the interaction of both static and dynamic stabilizers.
The presence of Hill-Sachs and Bankart lesions can significantly increase the likelihood of repeated shoulder dislocations
The Latarjet procedure is a reliable and successful method for treating shoulder instability. This procedure preserves the connection between the conjoint tendon and the coracoid process. The "sling" effect created by this procedure helps to prevent the shoulder from dislocating anteriorly.
Despite its success, the Latarjet procedure is associated with a reported complication rate of approximately 15%, with osteolysis the transferred coracoid bone graft, being one such complication.
Coracoid bone transplant osteolysis can occur due to a combination of biological and biomechanical influences. Biological factors include the shape and size of the graft and glenoid and the availability of blood supply. Biomechanical factors involve the stability and appropriate mechanical loading. Infection can also contribute to graft failure.

AIM:
To delineate the incidence of coracoid bone graft osteolysis following the Latarjet procedure for recurrent traumatic anterior shoulder dislocation.
