Transverse humeral ligament

The transverse humeral ligament of the shoulder joint.

The Transverse Humeral Ligament is a narrow sheet of connective tissue located in the human shoulder. It is a small fibrous band that extends from the lesser tubercle to the greater tubercle of the humerus, the bone of the upper arm or forelimb forming joints at the shoulder and the elbow.

Anatomy

The transverse humeral ligament is a part of the shoulder joint complex. It forms a canal through which the long head of the biceps brachii muscle passes. The ligament is attached to the two tubercles of the humerus, which are bony protrusions located at the top of the bone. The lesser tubercle is found on the front of the humerus, while the greater tubercle is located on the top of the bone.

Function

The primary function of the transverse humeral ligament is to hold the tendon of the long head of the biceps brachii muscle in the intertubercular groove of the humerus. This allows the tendon to remain in place during movements of the arm and shoulder, ensuring smooth and coordinated motion.

Clinical Significance

Damage to the transverse humeral ligament can result in a condition known as biceps tendonitis, which is characterized by inflammation and pain in the upper arm. This condition is commonly seen in athletes and individuals who perform repetitive overhead movements.
