    Objective: Anterior interosseous nerve (AIN) lesions are rare and a few nerve conduction measurements have been reported. The purpose of this retrospective study was to assess the diagnostic value of the motor nerve conduction measurements for the AIN lesion and to investigate its electrodiagnostic features. Methods: Twenty-three patients with AIN lesion were reviewed after a mean follow-up of 13 months. Of these 23 cases, a complete palsy of flexor pollicis longus (FPL) and flexor digitorum profundus to the index finger (FDP1) was seen in five, and an isolated palsy of FPL in three and that of FDP1 in two, while pronator quadratus (PQ) was weak in twelve. The compound muscle action potential (CMAP) from the PQ muscle and the FPL muscle were recorded and analyzed. Twenty-two patients were treated conservatively and one underwent surgery. Results: Both PQ-CMAP and FPL-CMAP were recor.. View More»
