Abstract des Autors

The latissimus dorsi muscle is one of the largest muscles in the body. Its origin extends from the thoracic spine and thoracolumbar fascia to the iliac crest. The muscle fibers converge toward the axilla to spiral beneath the anterior border of the teres major muscle and to insert onto the crest of the lesser tuberosity and the medial aspect of the bicipital groove of the proximal humerus. Functionally, the latissimus dorsi muscle adducts, internally rotates, and extends the shoulder. Acting with the pectoralis major and teres major muscles, the latissimus dorsi muscle helps to depress the raised arm against resistance and to pull the trunk upward and forward when the arms are fixed above the head, as in climbing. We report a case of an acute traumatic tear of the latissimus dorsi tendon from its insertion in an athlete. The diagnosis and treatment of this condition and a review of the related literature are discussed. Verf.-Referat
