Thumb Collateral Ligament Injuries, most commonly ulnar collateral (UCL), are athletic injuries that lead to a decrease in effective thumb pinch and grasp. Diagnosis relies upon thumb MCP radial-ulnar stress exam and MRI studies.

The ulnar collateral ligament (UCL) of the thumb is a strong band of tissue running along the inside of the metacarpophalangeal (MCP) joint, which is where the thumb meets the palm. This ligament keeps your thumb stable, especially when you pinch and grasp things.

Gamekeeper's thumb (also known as skier's thumb or UCL tear) is a type of injury to the ulnar collateral ligament (UCL) of the thumb. The UCL may be merely stretched, or it may be torn from its insertion site into the proximal phalanx of the thumb. [1]

Ulnar collateral ligament tears of the thumb metacarpophalangeal joint are common. MRI is the imaging modality of choice for assessing patients with equivocal findings and in identifying ligament injuries which require surgical repair, such as the commonly occurring Stener lesion.

The ulnar collateral ligament of the thumb is located on the pinky side of the thumb at the metacarpal-phalangeal joint (where the finger bones meet the hand bones). It provides stability at the base of the thumb and supports grip and hand strength. Injuries are …

The Metacarpophalangeal (MCP) joint of the thumb are stabilize by two major ligaments. The ulnar collateral ligament (UCL) and the Radial collateral ligament (RCL) . The UCL is more commonly injured, usually from forced radial deviation (abduction) of the thumb, while the RCL are rarely injuried.

2024年10月27日 · The most frequently affected ligament in thumb injuries is the ulnar collateral ligament (UCL), which is situated on the inner side of the joint where the thumb connects to the palm. Damage to this ligament can lead to pain, instability, and a loose sensation in the thumb, potentially impairing the ability to grip or pinch objects effectively.
