Split median nerve. A report of two cases.
Two variations of the median nerve described in the Lanz study as type 3 anomalies were found during dissection. In the first case the median nerve splits in the cubital fossa and descends through the carpal tunnel to the palm of the hand. In the second of the reported cases the median nerve splits 45 mm before entering the carpal tunnel and is accompanied by a persistent median artery. Surgeons should take such variations into consideration in order to plan surgical approaches judiciously.
