Diagnosis of Cubital Tunnel Syndrome
Clinical evaluation Sometimes nerve conduction studies Diagnosis of cubital tunnel syndrome is often possible clinically. However, if clinical diagnosis is equivocal and when surgery is being considered, Nerve conduction studies are done. Cubital tunnel syndrome is differentiated from ulnar nerve entrapment at the wrist (in Guyon canal) by the presence of sensory deficits over the ulnar dorsal hand, by the presence of ulnar nerve deficits proximal to the wrist on muscle testing or nerve conduction velocity testing, and by the elicitation of ulnar hand paresthesias by tapping the ulnar nerve in the cubital tunnel at the elbow (positive Tinel sign). Cubital tunnel syndrome may be confused with proximal nerve compression such as that caused by
