The ligamentum coracohumerale is a term used in anatomy to refer to a ligament located in the shoulder joint. It is a strong fibrous band that connects the coracoid process of the scapula (shoulder blade) to the greater tubercle of the humerus (upper arm bone).
This ligament plays a crucial role in providing stability and support to the shoulder joint. It helps to maintain the proper alignment of the scapula and humerus during arm movement, preventing excessive rotation or dislocation of the joint. The ligamentum coracohumerale also functions to limit the range of motion of the shoulder joint, preventing hyperextension or excessive stretching of the surrounding muscles and tendons.
The ligamentum coracohumerale is composed of dense connective tissue, primarily collagen fibers, which give it strength and flexibility. It is an intrinsic component of the joint capsule, which surrounds the shoulder joint, providing reinforcement and structure.
Injuries to the ligamentum coracohumerale can occur due to trauma, repetitive stress, or overuse. These injuries may result in shoulder instability, pain, and reduced range of motion. Treatment typically involves conservative measures such as rest, ice, physical therapy, and anti-inflammatory medications. Severe cases may require surgical intervention to repair or reconstruct the ligament.
Coracohumeral ligament, accessory ligament of the shoulder, passing between the external border of the root of the coracoid process and the neck of the humerus close to the great tuberosity.

The word "ligamentum coracohumerale" is derived from Latin, with the following breakdown:
1. Ligamentum: This is a Latin word meaning "ligament" or "band". It comes from the Latin verb "ligare", which means "to bind" or "to tie".
2. Coracohumerale: This is a compound word consisting of two Latin roots - coraco and humerale:
- Coraco: This root is derived from the Latin word "coracoides", which means "like a crow's beak". The term coracoid is used in anatomy to refer to a process or structure resembling a crow's beak, most notably the coracoid process of the scapula bone.
- Humerale: This root is derived from the Latin word "humerus", which means the upper-arm bone or the shoulder joint.
