Which ligaments compose the coracoclavicular ligament?

The coracoclavicular ligament is composed of two distinct ligaments: the conoid ligament and the trapezoid ligament. These ligaments function together to connect the coracoid process of the scapula to the clavicle. This connection provides significant stability to the acromioclavicular joint, helping to prevent dislocations and supporting the position of the shoulder girdle.

The conoid ligament is oriented more vertically and is responsible for limiting superior displacement of the clavicle. In contrast, the trapezoid ligament is horizontal and assists in limiting anterior and posterior movement of the clavicle relative to the scapula. Collectively, they reinforce the coracoclavicular joint and contribute to the overall stability of the shoulder complex.

Understanding these anatomical relationships is crucial for physical therapy practice, as injuries to these ligaments can result in shoulder instability or other complications, and rehabilitation strategies can be tailored accordingly.
