The ulnar collateral ligament is an important stabilizer of the thumb. It is on the radial side of the wrist, but on the ulnar side of the thumb. It should not be confused with the ulnar collateral ligament of wrist joint. Clinical significance. Injuries to it cause instability and loss of function of the thumb. Acutely this injury is known as

Tears of the ulnar collateral ligament account for about 50% of hand injuries in skiing athletes, with a forced abduction and hyperextension of the thumb [ 1 , 4 , 22 ].

Back to topSkier's thumb (Gamekeeper's thumb) What is it? Treatment consists of either a period of splintage or a repair of the ligament with an operation. If the ligament is torn or ruptured, the doctor may recommend surgery to repair the ligament. What can a hand therapist do for me?

A Stener lesion is a complete tear of the ulnar collateral ligament (UCL) from the thumb proximal phalanx at the level of the metacarpophalangeal (MCP) joint that is displaced superficial to the adductor pollicis aponeurosis, leading to interposition of the aponeurosis between the UCL and the MCP joint.

The most common site of injury in the thumb is the ulnar collateral ligament (UCL)   Acute UCL tears typically present with swelling, tenderness, and ecchymosis over the UCL with weakness and pain in pinch and key grip. Frank instability can be  Mar 29, 2018 A ulnar collateral ligament (UCL) of the thumb typically occurs when the thumb is forcibly pushed outward and extended away from the hand. UCL repair surgery is a procedure to treat an injury to the UCL, the soft tissue that connects the bones of the thumb and provides stability to the thumb joint.

This injury is caused by a force that pushes the thumb away from the fingers, creating pain, bruising and swelling in the area and can be caused by a single force 

An ulnar collateral ligament tear is often called a skier’s thumb or a gamekeeper’s thumb; skier’s thumb describes an acute injury and gamekeeper’s thumb a chronic injury, but the terms are often used interchangeably 3 4 .

The amount of flexion required for examina-tion and degree of angulation that indicates a complete tear of the proper collateral ligament varies between authors (see Table 1). Since measuring angulation without Treatment of Partial Ulnar Collateral Ligament Tears in the Elbow With Platelet-Rich Plasma Luga Podesta, MD , Scott A. Crow, MD , Dustin Volkmer, MD , Timothy Bert, MD , and Lewis A. Yocum, MD The American Journal of Sports Medicine 2013 41 : 7 , 1689-1694 Ulnar collateral ligament (UCL) injuries occur 10 times more frequently than radial collateral ligament (RCL) injuries. UCL injuries occur via thumb MCP hyperabduction or hyperextension ; in contrast, RCL injuries result from a forced or sudden thumb MCP adduction moment.

If the ulnar collateral ligament is pulled far enough, it will tear. While there are many ways to injure the ulnar collateral ligament, a skier’s thumb is the proper name for an acute injury to the ligament. Thumb Ulnar Collateral Ligament Tear Patient Education Overview.

These ligaments are located deep to the adductor aponeurosis of the thumb and stabilize the first metacarpophalangeal (MCP) joint. Tears can occur if a valgus force is applied to an abducted first MCP joint. Collateral ligament injuries cause instability of thumb grip and pinch; most frequently, the ulnar collateral ligament of the metacarpophalangeal joint is affected [1–3, 13, 18–21].

If the force is too strong, the ligaments can tear. They may even tear completely. This condition, also called skier’s thumb, is an acute sprain or tear of the ulnar collateral ligament (UCL) on the ulnar side of the metacarpal-phalangeal (MCP) joint of the thumb. A related condition, called gamekeeper’s thumb, is a chronic injury that develops over time from repeated stretching of the UCL. The metacarpophalangeal (MCP) joint of the thumb plays an important role in normal hand gripping and pinching. The radial and ulnar collateral ligaments (UCL) are the primary stabilizers to varus and valgus stress on this joint.
