coracoclaviculärligamenten

The coracoclavicular ligaments are a group of fibrous bands that connect the clavicle (collarbone) to the coracoid process of the scapula (shoulder blade). These ligaments play a crucial role in stabilizing the shoulder joint, particularly during movements that involve abduction and external rotation of the arm. There are two main coracoclavicular ligaments: the conoid ligament and the trapezoid ligament.

The conoid ligament is the larger and more significant of the two. It originates from the conoid tubercle of the clavicle and inserts into the coracoid process of the scapula. This ligament is particularly important for preventing superior displacement of the clavicle during abduction and external rotation of the arm.

The trapezoid ligament is smaller and less significant compared to the conoid ligament. It originates from the trapezoid line of the clavicle and inserts into the coracoid process of the scapula. The trapezoid ligament is less frequently involved in shoulder instability but can contribute to the overall stability of the shoulder joint.

Injuries to the coracoclavicular ligaments can occur due to trauma, such as falls, sports injuries, or motor vehicle accidents. These injuries can result in pain, swelling, and limited range of motion in the shoulder. Treatment for coracoclavicular ligament injuries typically involves rest, ice, compression, and elevation (RICE), along with physical therapy to restore strength and mobility. In severe cases, surgical intervention may be necessary to repair the damaged ligaments.

The coracoclavicular ligaments are essential for maintaining the integrity and stability of the shoulder joint, allowing for a wide range of motion and functional movement. Understanding the anatomy and function of these ligaments is important for diagnosing and treating shoulder injuries effectively.
