Dorsal radiocarpal ligament

The Dorsal Radiocarpal Ligament (DRCL) is a ligament in the human wrist. It is one of the main ligaments that provide stability to the wrist joint. The DRCL is located on the dorsal (back) side of the wrist, connecting the radius bone to the carpal bones.

Anatomy

The Dorsal Radiocarpal Ligament originates from the dorsal rim of the radius and extends diagonally to the dorsal surface of the carpal bones. It is a broad, thin, and quadrilateral ligament that is stronger and more defined than the Palmar Radiocarpal Ligament.

Function

The primary function of the Dorsal Radiocarpal Ligament is to stabilize the wrist joint and prevent excessive movement. It restricts flexion and ulnar deviation of the wrist, thus contributing to the overall balance and strength of the wrist.

Clinical Significance

Injury to the Dorsal Radiocarpal Ligament can result in instability of the wrist, pain, and limited range of motion. Treatment may involve physical therapy, immobilization, or in severe cases, surgical intervention.
