Dorsal carpometacarpal ligaments

== Dorsal Carpometacarpal Ligaments ==

The dorsal carpometacarpal ligaments are a group of ligaments located in the hand. These ligaments play a crucial role in stabilizing the carpometacarpal joints of the second, third, fourth, and fifth metacarpal bones with the distal row of carpal bones.

Anatomy

The dorsal carpometacarpal ligaments are situated on the dorsal (back) side of the hand. They connect the metacarpal bones to the carpal bones, specifically the trapezium, trapezoid, capitate, and hamate bones. These ligaments are part of the complex network of structures that provide stability and facilitate movement in the hand.

Function

The primary function of the dorsal carpometacarpal ligaments is to stabilize the carpometacarpal joints during hand movements. They help maintain the alignment of the metacarpal bones with the carpal bones, allowing for efficient transmission of forces and coordination of movements. These ligaments also contribute to the overall strength and dexterity of the hand.

Clinical Significance

Injuries to the dorsal carpometacarpal ligaments can result from trauma, such as falls or direct impacts to the hand. Such injuries may lead to pain, swelling, and instability in the affected joints. Proper diagnosis and treatment are essential to restore function and prevent long-term complications.
