Ligaments Intercarpal Palmar

Palmar intercarpal ligaments (lat. l. intercarpea palmaria, pna) are paired ligaments of the hand located in its palmar part. They connect the wrist bones to each other and strengthen the joint between them.

The palmar intercarpal ligaments are divided into superficial and deep parts. The superficial part is a transverse ligament running from the scaphoid to the hamate. It covers the finger tendons. The deep part consists of bundles of collagen fibers that run in different directions between the bones of the wrist.

The intercarpal palmar ligaments strengthen the wrist joint, limit excessive movement of the bones relative to each other, and protect and stabilize the digital flexor tendons that pass through the wrist. Damage to these ligaments can lead to wrist instability and impaired hand function.
