  Objective: Ulnar tunnel syndrome (UTS) is an uncommon ulnar neuropathy. Clinical and electrophysiological diagnosis of UTS is difficult. The purposes of this study were to assess the diagnostic value of the nerve conduction measurements for UTS caused by ganglion, and to investigate the electrophysiological features of UTS. Methods: The subjects were five patients with UTS. Before surgery, all patients had motor weakness and intrinsic muscle atrophy with positive Froment’s sign, and three patients had numbness and hypesthesia in the ulnar nerve distribution. In all patients, a magnetic resonance imaging (MRI) of the wrist demonstrated soft tissue mass at the ulnar tunnel. The compound muscle action potential (CMAP) from the abductor digiti minimi (ADM) muscle and the first dorsal interosseous (FDI) muscle, and sensory nerve action potenti.. View More»
