Cubital Tunnel Syndrome (CuTS) is the second most common upper-limb compression neuropathy and results from compression of the ulnar nerve at the elbow, most commonly within the cubital tunnel behind the medial epicondyle. It typically presents with numbness and tingling in the little finger and ulnar half of the ring finger, often worsening with prolonged elbow flexion or pressure on the elbow. Progressive disease leads to intrinsic hand muscle weakness, reduced grip strength, positive Froment and Wartenberg signs, and eventual clawing of the ring and little fingers. Diagnosis is primarily clinical and supported by nerve conduction studies and electromyography. Treatment ranges from activity modification and night splinting in mild cases to surgical decompression or ulnar nerve transposition for persistent or severe disease.
