Nerve Entrapments — Cubital Tunnel Syndrome

Second most common compression neuropathy after CTS; affects ulnar nerve at elbow. Symptoms: paresthesias in ulnar digits, weakness of intrinsic hand muscles. Tests: Tinel’s at elbow, elbow flexion test, Froment’s sign, Wartenberg’s sign. Investigations: NCS/EMG confirm slowed conduction across elbow. Management: activity modification, splinting; surgical decompression/transposition if persistent.
