Dorsal intercarpal ligament

Dorsal intercarpal ligament

The dorsal intercarpal ligament is a ligament located in the wrist. It is one of the key structures that contribute to the stability and function of the carpal bones.

Anatomy

The dorsal intercarpal ligament is situated on the dorsal (posterior) aspect of the wrist. It connects the carpal bones in the proximal and distal rows, specifically spanning from the triquetrum to the scaphoid, lunate, and trapezium bones. This ligament is part of the complex network of ligaments that stabilize the wrist joint.

Function

The primary function of the dorsal intercarpal ligament is to provide stability to the carpal bones, preventing excessive movement and maintaining the alignment of the bones during wrist motion. It plays a crucial role in the overall mechanics of the wrist, contributing to both the stability and flexibility required for various hand movements.

Clinical Significance

Injuries to the dorsal intercarpal ligament can result from trauma, such as falls or direct impacts to the wrist. Damage to this ligament can lead to instability of the carpal bones, resulting in pain, swelling, and reduced range of motion. Diagnosis of ligament injuries often involves physical examination and imaging techniques such as MRI or CT scan.

Related Structures

The dorsal intercarpal ligament works in conjunction with other ligaments in the wrist, including the palmar intercarpal ligament, radial collateral ligament, and ulnar collateral ligament. These ligaments collectively ensure the stability and proper function of the wrist joint.
