Coracoclavicular ligament

The main role of the coracoclavicular ligament is to provide support and stability to the acromioclavicular joint, which connects the clavicle to the acromion of the scapula. This ligament forms a vital part of the shoulder girdle by preventing dislocation of the joint during movements such as lifting and throwing. When the shoulder experiences stress, the coracoclavicular ligament helps absorb the force and maintain the alignment of the clavicle with the scapula. Additionally, it plays a role in facilitating proper biomechanics of the shoulder, allowing for a greater range of motion while preventing injury during activities involving the upper extremity.

The coracoclavicular ligament is anchored to the coracoid process, which is a small hook-like bony projection on the scapula, located on its anterior aspect. It extends diagonally upwards and laterally to attach to the inferior surface of the clavicle. This ligament lies just below the acromioclavicular joint, which is formed where the clavicle meets the acromion of the scapula. Its strategic position allows it to effectively stabilize the joint while permitting fluid movements of the shoulder and arm.

• Injuries to the coracoclavicular ligament can occur during falls or sports, leading to shoulder instability.
• The coracoclavicular ligament is supported by nearby muscles, such as the trapezius and deltoid, which help distribute forces acting on the shoulder.
• The conoid and trapezoid parts of the ligament assist in differentiating its functional integrity during anatomical discussions.
