During the examination of a pitcher with medial elbow pain, which test is likely to be positive?

• A. Varus stress testing
• B. Valgus stress testing
• C. Tinel's test
• D. Lateral scapular slide test

Answer: (B)

In the context of a pitcher experiencing medial elbow pain, the involvement of the ulnar collateral ligament (UCL) is a common concern. The valgus stress test specifically evaluates the integrity of the UCL, which is located on the medial aspect of the elbow. During this test, a valgus force is applied while the elbow is in various degrees of flexion. If the ligament is compromised, there is likely to be increased joint laxity or pain, which would make the test positive.

The other tests mentioned are useful for different conditions or structures. Varus stress testing assesses lateral instability, specifically regarding the lateral collateral ligament. Tinel's test is used to determine ulnar nerve entrapment at the elbow. The lateral scapular slide test evaluates scapular dyskinesis, which is unrelated to elbow pathology. Therefore, in the case of medial elbow pain, the valgus stress test is the most relevant examination method that would yield a positive result, indicating potential involvement of the UCL.
