Electrophysiological Study of Berrettini Anastomosis

The common opinion that sensory supply of digit 5 (D5) and medial half of digit 4 (D4) of the hand is by ulnar nerve, while the lateral half of D4 and the remaining digits is by median nerve is an oversimplification of a complex topic. Indeed, the literature demonstrated that both the median and ulnar nerves display a number of deviations to the traditionally taught branching patterns.

The aim of our study was to investigate the physiological role of median and ulnar nerves in the sensory supply of D4.

Treatment and study plan

electrophysiological study

Other

Antidromic sensory nerve conduction studies of median and ulnar nerves will be performed on both hands of 30 healthy subjects with no history of previous neuromuscular disease and no abnormalities on neurological examination., by using surface electrical stimulation at wrist and surface digital recording electrodes on both sides of D4.

electromyograph

Device

surface electrical stimulation at wrist and surface digital recording electrodes on both sides of D4.

Primary outcomes

  1. analysis of the sensory potential (UV amplitude in MSEC) recorded on both sides of the IV finger of the hand by stimulation of the median nerve and the ulnar one

    Time frame: immediately after the procedure

  2. analysis of the sensory potential ( latency in MSEC) recorded on both sides of the IV finger of the hand by stimulation of the median nerve and the ulnar one

    Time frame: immediately after the procedure
