Riche-Cannieu Anastomosis: A Case Report

Abstract

Riche-Cannieu anastomosis is a rare type of anomalous innervation. A 44 years old woman who has numbness her hands evaluated by electromyography. Nerve conduction studies showed dual innervation (mainly ulnar nerve) of abductor pollicis brevis muscle bilaterally. Needle electromyography of bilateral abductor pollicis brevis and abductor digiti minimi muscles are found as normal. Ulnar to median anastomosis in the palm should be kept in mind in patient with unexpected electrophysiological results.
