KorakoClavicularbänder

The coracoclavicular ligaments are a pair of strong fibrous bands that connect the clavicle (collarbone) to the coracoid process of the scapula (shoulder blade). These ligaments are crucial for the stability and function of the shoulder joint, particularly in supporting the weight of the arm and enabling movements such as elevation and rotation of the scapula.

The two distinct ligaments are the conoid ligament and the trapezoid ligament. The conoid ligament is located medially and originates from the conoid tubercle on the underside of the clavicle, fanning out to insert onto the posterior aspect of the coracoid process. The trapezoid ligament lies anterior and lateral to the conoid ligament. It originates from the trapezoid ridge on the underside of the clavicle and inserts onto the superior surface of the coracoid process.

Together, these ligaments form a strong sling that suspends the scapula from the clavicle. They prevent excessive superior and posterior displacement of the clavicle relative to the scapula. Injuries to the coracoclavicular ligaments, such as tears or sprains, often occur during falls or direct trauma to the shoulder. These injuries can lead to significant shoulder instability and pain, and in severe cases, may require surgical intervention to restore the integrity of the shoulder complex. The coracoclavicular ligaments play a vital role in the biomechanics of the shoulder girdle, ensuring proper articulation between the clavicle and scapula.
