title: [Pronator teres syndrome. Clinical and neurophysiological study of 2 cases].
abstract: We report two cases of pronator teres syndrome (bilateral in one case) diagnosed in our Department by electromyographic studies during the last three years. The infrequency of this syndrome (1 case/201 cases of carpal tunnel syndrome), combined with the unspecified and inconsistent symptomatology (tenderness over the pronator teres, paresthesias and weakness of flexor pollicis longus, abductor pollicis brevis and opponens pollicis) frequently induced diagnostic mistakes. The electromyographic study is very useful showing a delay in proximal motor latency of the median nerve, diminution of motor nerve conduction in the proximal forearm segment of this nerve with normality of distal motor latency and sensory latency. Corticoid infiltration is the treatment of choice keeping in reserve surgery only for resistant cases.
