What are the glenohumeral ligaments?

Glenohumeral ligaments (GHL) are a set of three bonds located on the front of the shoulder joint that combine the glueid fossu of the shoulder blade or shoulder, with the upper part of the humerus at the top of the arm. These bonds cooperate in conjunction with the co -humeral ligament to maintain the stability of glenohumeral or shoulder joints during most of the extremes of arms movement. They are named after their relative position in the shoulder joint.

Superior Glenohumeral Ligaments (SGHL) have two points of origin, one on a supraglenoid tubercle and one at the base of the coracoid process, both parts of the sapule; The insertion point is for a smaller tuberosity of the humerus. Medium glenohumeral ligaments (MGHL) have a single point of origin in the anatomical neck of the humerus. The insertion point is in the middle front of the gllenoid labrum, the cartilage around the gluenoid fossa, which increases the socket of the glenohumeral joint. Inferior glenohumeral ligaments (IGHL) have a point of origin in the lower front of the glenoid labrum. This ligament is divided into two parts before insertingFront and rear, along the axillary case. The voltage only develops in bindings, because the position of the humerus changes during movement. The ligaments are tightened with tension and shorten and reduce the movement of the joint.

When the arms are calm, GHL is lax and flexible. ADUCTION, when it is reduced, causes SGHL to tighten while two more glenohumeral ligaments are released. The kidnapping, or lifting the arm, causes SGHL to relax and extend, and at the same time download MGHL and IGHL.

Turned causes GHL to either release or download, depending on the type of rotation. Stretching the arm directly to the side before the circular movement causes side rotation of the shoulder joint and tension on the ligaments. When the arms hang from the shoulder joint before moving, the movement is called media rotation. During this movement, glenohumeral ligaments are released, allowing a greater range of movement.

Surgical change of glenohumeral bindings may allow a greater range of movement limitEven people who have difficulty moving the shoulder joint during normal daily activities. The glenohumeral joint capsules can be surgically moved to change the effect of binding on the movement of the arm. The surgeon may consume the frayed medium glenohumeral ligament to allow movement in a frozen or immobile shoulder joint.
