Anatomy and Applied Anatomy of the Shoulder Joint

Ligaments Stabilizing the Shoulder Joint

The shoulder joint, known as the glenohumeral joint, is one of the most mobile joints in the human body. This mobility is achieved at the expense of stability, making it crucial for various ligaments to support and reinforce the joint.

Coracoclavicular Ligament

The coracoclavicular ligament plays a significant role in stabilizing the clavicle and preventing excessive movement between the scapula and clavicle.

Glenohumeral Ligaments

The glenohumeral ligaments (superior, middle, and inferior) contribute to stabilizing the humeral head within the glenoid cavity.

Acromioclavicular Ligament

The acromioclavicular ligament provides reinforcement to the acromioclavicular joint, limiting excessive translation and rotation.

Clinical Significance

Understanding these ligaments is crucial for diagnosing shoulder injuries such as dislocations and ligament tears.
