A Stener lesion is a type of traumatic injury to the

phalanx. No longer in contact with its insertion site, the UCL cannot spontaneously heal.[1]

Mechanism

Main article:
Gamekeeper's thumb

In 1962, Bertil Stener described a

anatomic position. Consequently, the severed ligament would fold on itself and thus be prevented from healing and restoring stability to the MCP joint.[2]

For a Stener lesion to occur, both the proper and accessory collateral ligaments of the thumb must be completely ruptured. The Stener lesion is present in more than 80% of complete ruptures of the UCL of the thumb.[citation needed]

Treatment

The ulnar collateral ligament is an important stabilizer of the thumb. Thumb instability resulting from disruption of the UCL profoundly impairs the overall function of the involved hand. Because of this, it is critical that these injuries receive appropriate attention and treatment.[citation needed]

Most gamekeeper's thumb injuries are treated by simply immobilizing the joint in a thumb spica splint or a modified wrist splint and allowing the ligament to heal. However, near total or total tears of the UCL may require surgery to achieve a satisfactory repair, especially if accompanied by a Stener lesion.[3]

History

CS Campbell, an orthopedic surgeon, originally coined the term "gamekeeper's thumb" in 1955, after he observed this condition in a number of Scottish

abducted metacarpophalangeal (MCP) joint. Over time, this would lead to insufficiency of the ulnar collateral ligament of the thumb, a condition which Campbell referred to as "gamekeeper's thumb".[citation needed
