Sprained Thumb Evaluation
The evaluation of skier's thumb begins with a history and physical examination.
Physical findings in someone with skier's thumb may include:
- Bruising at the base of the thumb
- Stretched or torn ulnar collateral ligament:
- The joint between the thumb and hand bends abnormally during examination
- Swelling at the base of the thumb
- Tenderness at the base of the thumb
Tests are not necessary to make the diagnosis of skier's thumb. X-rays may be required to exclude a thumb fracture.
Tests that may be used to evaluate skier's thumb include:
