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

Initial treatment involves immobilization and anti-inflammatory medications.

Rehabilitation Exercises

1. Thumb range-of-motion exercises
2. Strengthening exercises
3. 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.

Affected Areas

• Thumb base
• Metacarpophalangeal joint
