Carpal collateral ligament

Carpal collateral ligament is a term used in anatomy to refer to one of the ligaments in the wrist. It is part of the complex structure of the wrist that includes bones, joints, and soft tissues. The carpal collateral ligament plays a crucial role in the stability and flexibility of the wrist.

Anatomy

The carpal collateral ligament is located on the sides of the wrist. There are two carpal collateral ligaments: the radial collateral ligament, which is on the thumb side of the wrist, and the ulnar collateral ligament, which is on the little finger side. These ligaments connect the radius and ulna bones of the forearm to the carpal bones of the wrist.

Function

The primary function of the carpal collateral ligament is to provide stability to the wrist. It helps to prevent excessive side-to-side movement of the wrist. This is particularly important during activities that require a strong grip or wrist rotation.

Clinical significance

Injury to the carpal collateral ligament can occur due to trauma, such as a fall on an outstretched hand, or from repetitive strain. Symptoms of a carpal collateral ligament injury may include pain, swelling, and decreased range of motion in the wrist. Treatment may involve rest, physical therapy, or in severe cases, surgery.
