Normal values for the distal portion of the ulnar nerve are proposed. In 52 normals without clinical symptoms of peripheral nerve lesion the following neurographic parameters were recorded on the right side and in 45 cases on the left side, too: distal latency wrist-hypothenar, compound action potential from hypothenar, distal latency wrist-M, adductor pollicis, compound action potential from the M. adductor pollicis, antidrome nerve conduction velocity wrist-digit V, difference of latencies M. adductor pollicis-hypothenar, difference of compound action potential hypothenar-M. adductor pollicis and side differences of these parameters. A linear regression analysis was performed to investigate the dependence of these parameters from age. Our normal values allow an exact localisation of peripheral lesions of the ulnar nerve (Loge de Guyon, Ramus volaris superficialis, Ramus profundus).
