Which positive signs might indicate Cubital Tunnel Syndrome?

• A. + Tinel’s sign and + Finkelstein's sign
• B. + Phalen's sign and + Wartenburg's sign
• C. + Wartenburg's sign and + Tinel’s sign
• D. + Elbow flexion test and + Homan's sign

Answer: (C)

Cubital Tunnel Syndrome is a condition that involves compression of the ulnar nerve at the elbow, leading to symptoms such as numbness, tingling, and weakness in the hand. The positive signs commonly associated with this syndrome help in diagnosing the condition based on nerve irritation and its effects on function.

Tinel's sign is specifically used to evaluate irritation of a nerve, where tapping over the ulnar nerve at the cubital tunnel produces tingling sensations in the ulnar nerve distribution. This positive sign strongly correlates with Cubital Tunnel Syndrome, indicating that the ulnar nerve may be compromised at that site.

Wartenburg's sign is another important indication. It is characterized by the inability to adduct the little finger, often due to weakness in the interossei muscles that are innervated by the ulnar nerve. When this sign is present, it suggests that the ulnar nerve is not functioning properly, further supporting a diagnosis of Cubital Tunnel Syndrome.

In contrast, the other combinations involve tests that either assess different areas or conditions unrelated to the ulnar nerve at the cubital tunnel, making them less relevant in the context of diagnosing Cubital Tunnel Syndrome. For example, the Elbow flexion test
