Abstract.

Subcoracoid impingement is a rare but well-know cause of anterior shoulder pain in throwing and overhead athletics. Bulging of the walls or the contents of the coracohumeral space may hamper the smooth gliding of soft tissue between the coracoid process and glenohumeral joint, especially in forward elevation and internal rotation of the arm. Following is a case report of subcoracoid impingement caused by an accessory coracobrachialis muscle in an alpinist treated by resection of the muscular supernumerary slip.

Résumé.

Le conflit sous coracoïdien est une cause rare mais bien connue de douleur antérieure de l'épaule chez les sportifs de lancer. Toute augmentation de volume des parois ou du contenu de l'espace coraco-huméral gêne le glissement des parties molles entre le processus coracoïde et l'articulation scapulo-humérale principalement lors de l'antepulsion et de la rotation interne du bras. Les auteurs rapportent un cas de conflit sous-coracoïdien dû à un muscle coraco-brachial accessoire chez un alpiniste et traité par simple résection du faisceau musculaire surnuméraire.
