Transverse Carpal Ligament

**The carpal ligament** is a complex of fibers located anteriorly and posteriorly at the level of the distal forearm. Consists of the superficial and deep transverse carpal ligaments. The first is located slightly below the capsular ligamentous tissue, and the second is another millimeter posterior and connects to the head of the radius below. Thus, the transverse ligament forms a single complex with other fibers of the joint of the wrist and the entire forearm, which makes it stronger and more stable. It lies deep in the interosseous muscles and can be strongly intertwined with the joint capsule, including its lateral edge.

**Transverse ligament:**

It is a fibrous structure located on the anterior surface of the dorsum of the wrist; It has a medial attachment on the distal edge of the bony protrusion, which is part of the dorsal surface of the radius and ulna; The lateral insertion lies on the posterior border of the first row of carpal bones; Covered by the pronator teres tendon (extensor finger); Provides stability to the upper and lower carpometacarpal joints and facilitates pronation of the forearm; It prevents the wrist from extending more than 5 degrees even in conditions of very strong stretching of all other ligaments of the joint or direct tension of the capsular fibers; Holds the palm and fingers in a position opposite to the tilt of the forearm to the right or left (then
