A 48-year-old man presents with numbness and tingling of the little finger and ulnar half of the ring finger for 8 months. He has weakness of grip and difficulty crossing fingers. Nerve conduction studies show slowed conduction velocity across the elbow. He has failed 3 months of night splinting. The recommended surgical treatment is:

• A Carpal tunnel release
• B Guyon's canal release
• C Cubital tunnel release with ulnar nerve transposition ✓
• D Medial epicondylectomy as the only procedure

Explanation

Chronic cubital tunnel syndrome with failed conservative management is treated with cubital tunnel release, commonly combined with anterior ulnar nerve transposition (subcutaneous or submuscular). Guyon's canal is at the wrist (ulnar tunnel), carpal tunnel involves the median nerve, and medial epicondylectomy is an alternative but not the only standard.
