THE SHOULDER JOINT LIGAMENTS ✍️.
Shoulder ligaments are tough, fibrous connective tissues that link bones to one another, providing critical stability to the body’s most mobile joint. Because the shoulder's ball-and-socket structure favors a wide range of motion, these ligaments are essential for preventing dislocations and controlling movement.
The Shoulder Ligaments include :
Glenohumeral Ligaments (GHL): A group of three ligaments (superior, middle, and inferior) that form the main part of the joint capsule. They connect the humerus (upper arm bone) to the glenoid (socket) and are the primary source of shoulder stability.
Coracohumeral Ligament: Connects the coracoid process of the scapula (shoulder blade) to the humerus. It supports the superior part of the joint and helps limit external rotation.
Coracoacromial Ligament (CAL): Links two parts of the shoulder blade—the coracoid process and the acromion. It forms an arch over the joint to prevent the humeral head from shifting too far upward.
Coracoclavicular Ligaments (CCL): Consisting of the conoid and trapezoid ligaments, these connect the clavicle (collarbone) to the coracoid process. They provide vertical stability and keep the shoulder "square".
Acromioclavicular Ligament: Connects the acromion to the clavicle, providing horizontal stability to the acromioclavicular (AC) joint.
Transverse Humeral Ligament (THL): A small band that holds the long head of the biceps tendon in place within the groove of the humerus.
