The Palmar radiocarpal ligament is a ligament in the human body that is part of the wrist joint. It is also known as the anterior radiocarpal ligament or volar radiocarpal ligament. This ligament plays a crucial role in the stability and mobility of the wrist.

Anatomy

The palmar radiocarpal ligament is a broad, membranous band that extends from the distal end of the radius to the anterior surface of the proximal row of the carpal bones. It is attached above to the anterior margin of the lower end of the radius, and below to the scaphoid, lunate, and triquetral bones.

Function

The primary function of the palmar radiocarpal ligament is to limit the amount of extension at the wrist. It also helps to stabilize the wrist joint and prevent excessive movements that could lead to injury.

Clinical Significance

Injuries to the palmar radiocarpal ligament can lead to instability of the wrist joint, which can result in pain, decreased range of motion, and potential long-term complications such as arthritis. Treatment for injuries to this ligament typically involves rest, immobilization, and in severe cases, surgery.
