Existe un disco interpuesto entre las superficies articulares. En el punto en que se pone en contacto con estos tendones la membrana fibrosa se fusiona con ellos. La membrana fibrosa posee cuatro engrosamientos mas ademas del transverso que son un refuerzo anterosuperior del hombro. Los ligamentos glenohumerales carecen de firmeza necesaria para interferir en las luxaciones anteriores de la cabeza humeral.

Rodete glenoideo. Se da este nombre a un anillo fibrocartilaginoso que se aplica sobre el contorno de la cavidad glenoidea y que aumenta su profundidad. A menudo, el rodete glenoideo pasa a manera de puente superiormente a la escotadura glenoidea que presenta el borde anterior de la cavidad glenoidea. Describiremos sucesivamente los ligamentos coracohumeral,coracoglenoideo y glenohumerales.

Ligamento coracohumeral. Brodie denomina estos elementos fibrosos ligamento humeral transverso. Ligamento coracoglenoideo. Ligamentos glenohumerales. Existen tres: el ligamento glenohumeral superior, el ligamento glenohumeral medio y el ligamento glenohumeral inferior.

Este ligamento es casi transversal; en su parte lateral, los ligamentos glenohumerales medio e inferior entran en contacto e incluso se superponen; en este caso, es generalmente el ligamento glenohumeral medio el que pasa anterior al ligamento glenohumeral inferior.

Este agujero es en realidad triangular, al igual que el espacio interligamentoso en que se encuentra y el cual llena casi por completo. Hemos demostrado que existe muy a menudo, en el espacio triangular comprendido entre los ligamentos glenohumerales medio e inferior, un orificio que comunica la cavidad articular con la bolsa sinovial denominada subcoracoidea, por lo cual puede ser llamado orificio subcoracoideo.

Existe en la mitad de los casos. Publicado por.

¿Qué es la coracohumeral ligamento?

It is attached, by its apex, to the summit of the acromion just in front of the articular surface for the clavicle ; and by its broad base to the whole length of the lateral border of the coracoid process. This ligament, together with the coracoid process and the acromion, forms a vault for the protection of the head of the humerus. It is in relation, above, with the clavicle and under surface of the deltoid muscle ; below, with the tendon of the supraspinatus , a bursa being interposed. Its lateral border is continuous with a dense lamina that passes beneath the deltoid upon the tendons of the supraspinatus and infraspinatus. The ligament is sometimes described as consisting of two marginal bands and a thinner intervening portion, the two bands being attached respectively to the apex and the base of the coracoid process, and joining together at the acromion. When the pectoralis minor is inserted, as occasionally is the case, into the capsule of the shoulder-joint instead of into the coracoid process, it passes between these two bands, and the intervening portion of the ligament is then deficient.
