Latarjet revision surgery is a challenging procedure as the normal anatomy of the shoulder is severely modified and the coracoid and the conjoint tendon have been transferred to a non-anatomic position hidden behind the brachial plexus.

Computed tomography is the key imaging modality to assess the status of the graft and its ability to reconstruct bone defects when present. Accordingly, three main scenarios can be encountered depending on coracoid graft status: (1) shoulders with an unsuitable graft due to fragmentation or severe osteolysis; (2) shoulders with suitable coracoid graft but that is non-united, displaced or mispositioned, and (3) shoulders where the coracoid graft is well healed and positioned but in which the bone defects have not been properly reconstructed. Free bone graft is the recommended procedure if the coracoid has suffered osteolysis, fragmentation, or fracture. In those cases in which the bone graft is viable, but is malpositioned, avulsed or non-united, bone graft repositioning can be attempted. Adding a remplissage could be advisable if the properly positioned coracoid graft alone cannot convert off-track lesions into on-track. Finally, extra-articular capsular reinforcement is suggested in those patients in whom Latarjet failed due to hyperlaxity or poor soft tissue quality whenever the bone defects have been adequately reconstructed.

摘要

Latarjet revision surgery is a challenging procedure as the normal anatomy of the shoulder is severely modified and the coracoid and the conjoint tendon have been transferred to a non-anatomic position hidden behind the brachial plexus. It is crucial to investigate the cause of recurrence to choose the best treatment option. Computed tomography is the key imaging modality to assess the status of the graft and its ability to reconstruct bone defects when present. Accordingly, three main scenarios can be encountered depending on coracoid graft status: (1) shoulders with an unsuitable graft due to fragmentation or severe osteolysis; (2) shoulders with suitable coracoid graft but that is non-united, displaced or mispositioned, and (3) shoulders where the coracoid graft is well healed and positioned but in which the bone defects have not been properly reconstructed. Free bone graft is the recommended procedure if the coracoid has suffered osteolysis, fragmentation, or fracture. In those cases in which the bone graft is viable, but is malpositioned, avulsed or non-united, bone graft repositioning can be attempted. Adding a remplissage could be advisable if the properly positioned coracoid graft alone cannot convert off-track lesions into on-track. Finally, extra-articular capsular reinforcement is suggested in those patients in whom Latarjet failed due to hyperlaxity or poor soft tissue quality whenever the bone defects have been adequately reconstructed.
