What is Gamekeeper's Thumb (UCL Injury)?
Gamekeeper's Thumb is an injury to the ulnar collateral ligament (UCL) of the thumb, resulting in instability and pain.
- Often caused by a sudden force on the thumb
- Common in contact sports
Overview of the Condition
This condition leads to weakness and instability in the thumb, impairing grip and pinch strength.
Symptoms
- Pain and swelling at the thumb base
- Instability during pinching
- Weakness in grip strength
Causes
Often results from an acute hyperabduction injury to the thumb, commonly seen in sports.
Diagnosis
Diagnosis is based on physical examination, stress testing, and imaging studies such as MRI.
Treatment Options
- Immobilization with a thumb spica splint
- NSAIDs for pain relief
- Surgical repair for complete tears
Conservative Management
Initial treatment involves immobilization and anti-inflammatory medications.
Rehabilitation Exercises
- Thumb range-of-motion exercises
- Strengthening exercises
- Gradual return to functional activities
Surgical Options
Surgical repair of the UCL may be necessary for complete tears or in athletes requiring optimal thumb stability.
Anatomy Overview
The UCL of the thumb stabilizes the metacarpophalangeal joint and is essential for pinch strength.
