The Physical Exam

Your doctor will start by examining your thumb visually and through touch. They'll look for swelling and tenderness around the base of your thumb. The key test is called the valgus stress test. Your doctor will gently try to move your thumb away from your hand to check its stability. This might feel uncomfortable but is important for assessing the extent of the injury.

Imaging Tests

X-rays are often the first imaging test used. They can show if there's a small bone fragment broken off where the ligament attaches, which can happen in some cases of skier's thumb. If more detail is needed, your doctor might order an ultrasound or MRI. These tests can provide a clearer picture of the soft tissues, including the ligament itself.
Skier's thumb is a condition involving injury to the ulnar collateral ligament of the thumb, often requiring a valgus stress test for diagnosis.

Stress Radiography

In some cases, your doctor might perform a stress radiograph. This involves taking X-rays while applying gentle pressure to your thumb, similar to the valgus stress test. It allows them to see how much your thumb joint moves under stress, which can indicate the severity of the ligament injury.

FAQs

Are these tests painful?

They may cause mild discomfort but shouldn't be extremely painful.

How long do the tests take?

Do I need all these tests?

Not necessarily, your doctor will determine which are most appropriate.

Can these tests definitively diagnose skier's thumb?

In most cases, yes, but sometimes further evaluation may be needed.
