Understanding the Valgus Stress Test (Elbow) Assessment
To assess the integrity of the **Ulnar Collateral Ligament (UCL)** (Medial Collateral Ligament), which resists valgus forces.
Watch How It's Done
How do I start?
Patient is sitting or supine. The elbow is positioned in **20° to 30° of flexion** (unlocked position).
What happens?
The examiner applies a **valgus stress** (force directed laterally to medially) across the elbow joint while stabilizing the humerus.
In Plain English
What Does a Positive Result Mean?
**Excessive medial joint line gapping** compared to the unaffected side and/or reproduction of the patient's **medial elbow pain**.
Helpful Tip:
This test is crucial for diagnosing UCL sprains, common in throwing athletes.
Safety First
This guide is to help you understand what happens in a clinic. Do not try to diagnose yourself. If you have severe pain, swelling, or cannot put weight on your leg, please visit an urgent care center or your doctor immediately.
Other Elbow Tests
Elbow Quadrant Tests
A generalized term for assessing the **end-feel and range of motion** of the elbow joint in flexion and extension, often used to assess stiffness or loose bodies.
Cozen's Test
To detect **Lateral Epicondylitis** (Tennis Elbow), which is tendinopathy of the **Extensor Carpi Radialis Brevis (ECRB)** origin.
Mill's Test
To detect **Lateral Epicondylitis** (Tennis Elbow) by passively stressing the common extensor tendon origin.
Tinel's Test (at the Elbow)
To assess for irritation, regeneration, or entrapment of the **Ulnar Nerve** at the elbow (**Cubital Tunnel Syndrome**).
