Which ligament is associated with the stabilization of the shoulder joint?

The coracoacromial ligament plays a significant role in stabilizing the shoulder joint by forming an arch over the top of the humeral head. This ligament connects the coracoid process of the scapula to the acromion of the scapula, creating a protective space that helps to prevent dislocation of the shoulder joint. Its positioning and structure contribute to the stability of the shoulder, particularly during overhead activities and movements that place stress on the joint.

Other ligaments listed, while they serve various functions, do not primarily focus on stabilizing the shoulder joint in the same way. The costoclavicular ligament supports the connection between the clavicle and the first rib, and the conoid ligament is part of the coracoclavicular ligament complex, providing stability to the acromioclavicular joint. The transverse humeral ligament holds the biceps tendon in place within the bicipital groove, but does not provide significant stabilization to the shoulder joint itself.
