Electrophysiological Study of Berrettini Anastomosis

Not Applicable

Completed

• Conditions: Hand Anastomosis; Electrophysiologic Study
• Interventions: Other: electrophysiological study; Device: electromyograph

• Registration Number: NCT06458751
• Lead Sponsor: Fondazione IRCCS Ca' Granda, Ospedale Maggiore Policlinico

Brief Summary

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.
