Stener lesion
Stener Lesion
Stener lesion (/ˈstɛnər/; from the Swedish surgeon Urban Stener) is a type of injury to the ulnar collateral ligament (UCL) of the thumb. This injury is commonly associated with sports and physical activities.
Pronunciation
The term is pronounced as /ˈstɛnər/.
Etymology
The Stener lesion is named after the Swedish surgeon Urban Stener who first described this injury in 1962.
Definition
A Stener lesion occurs when the ulnar collateral ligament of the thumb is torn and displaced, causing it to become trapped outside its normal anatomic location. This prevents the ligament from healing properly, often leading to chronic instability and weakness of the thumb.
Related Terms
- Ulnar collateral ligament: A ligament located on the inner side of the thumb. When this ligament is damaged, it can lead to a Stener lesion.
- Gamekeeper's thumb: A colloquial term for an injury to the ulnar collateral ligament of the thumb. This term is often used interchangeably with Stener lesion, although not all UCL injuries result in a Stener lesion.
- Skier's thumb: Another term for an injury to the ulnar collateral ligament of the thumb, named for the common occurrence of this injury among skiers.
Treatment
Treatment for a Stener lesion typically involves surgery to reposition and repair the displaced ligament. Following surgery, the thumb is usually immobilized for a period of time to allow the ligament to heal.
