Carpal ligaments

From WikiMD's Wellness Encyclopedia

Carpal Ligaments are a complex network of ligaments located in the wrist that connect the carpal bones to each other and to the metacarpal bones and forearm bones. These ligaments are crucial for the stability and function of the wrist joint, allowing for a wide range of motion while also preventing excessive movements that could lead to injury.

Anatomy[edit | edit source]

The carpal ligaments can be divided into two main groups: the intrinsic and extrinsic ligaments.

Intrinsic Ligaments[edit | edit source]

The intrinsic ligaments are located entirely within the wrist and include:

Extrinsic Ligaments[edit | edit source]

The extrinsic ligaments originate or insert outside the carpal bones:

Function[edit | edit source]

The primary function of the carpal ligaments is to stabilize the wrist joint, allowing for controlled movements such as flexion, extension, abduction, and adduction. They also help to distribute forces across the wrist during activities, minimizing the risk of injury.

Clinical Significance[edit | edit source]

Injuries to the carpal ligaments, such as sprains or tears, are common and can result from acute trauma or chronic overuse. Conditions such as Carpal Tunnel Syndrome and Scapholunate Advanced Collapse (SLAC) can also affect the integrity and function of these ligaments, leading to pain, instability, and decreased wrist function.

Diagnosis and Treatment[edit | edit source]

Diagnosis of carpal ligament injuries typically involves a combination of physical examination, medical history, and imaging studies such as X-rays, MRI, or CT scan. Treatment may include rest, immobilization, physical therapy, or surgery, depending on the severity of the injury and the specific ligaments involved.
