Internal Coracoclavicular Ligament: Anatomy, Functions and Role in Joint Activity

Ligaments play an important role in maintaining joint stability and controlling joint movement. One of these ligaments is the internal coracoclavicular ligament (lat. l. coracoclaviculare internum). In this article we will look at the anatomy, functions and role of this ligament in joint activity.

Anatomy

The internal coracoclavicular ligament is a short and thick ligamentous structure located between the clavicle and the coracoid process of the scapula. It starts from the inner surface of the clavicle, directly under the external coracoclavicular ligament, and ends at the apex of the coracoid process. The internal coracoclavicular ligament consists of a bundle of collagen fibers reinforced with each other and connected to the surrounding tissues.

Functions

The internal coracoclavicular ligament performs several functions related to maintaining stability and controlling movement of the shoulder joint. It prevents the clavicula from rising upward and forward, which helps keep the scapula in a certain position. In addition, the internal coracoclavicular ligament limits the anterior displacement and rotation of the clavicula, and is also involved in controlling the movements of the arm during lifting and lowering.

Role in joint activity

The internal coracoclavicular ligament plays an important role in the joint activity of the shoulder. It helps maintain joint stability and prevent traumatic injury during various arm movements. For example, when lifting heavy objects, the internal coracoclavicular ligament helps hold the clavicula and scapula in a certain position, which prevents damage to soft tissues and articular surfaces.

In conclusion, the internal coracoclavicular ligament is an important ligamentous structure that plays an important role in maintaining stability and controlling motion at the shoulder joint. Understanding the anatomy, function and role of this ligament can help doctors and physical therapists treat shoulder injuries and diseases, as well as athletes improve performance and reduce the risk of injury.

**Ligamentous apparatus of the trunk,** **ligament coracoid clavicular internal** is a connective tissue structure consisting of the interligamentous apparatus of the anterior part of the chest wall. The superficial part of the ligamentous apparatus covers the upper pole of the sternum and has the shape of a beak, and the deep part originates on the upper pole of the sternum and consists of an internal ligament. The bone components of the ligamentous complex include the clavicle and scapula.
