Electrodiagnostic description of a rare variant of Berrettini anastomois: A case report

Abstract

Highlights In Berrettinni anastomosis, frequently a sensory communicating branch from ulnar nerve supplies digit 3. Despite anatomical evidence of ulnar communicating branch providing sensory supply to digit 2, there are no electrodiagnostic descriptions of the same. Electrodiagnostic findings in a patient with median nerve laceration were suggestive of ulnar sensory innervation of digit 2. Knowledge of existence of these communications and their electrodiagnostic features can prevent misdiagnosis and iatrogenic injuries.

Frequency of Type-1 Berrettini's Connection in a Neurophysiology Laboratory

“…19 In addition to the electrophysiological evidence of Berrettini's anastomotic communication to the middle finger, 1 7 8 a recent study has reported about Berrettini's anastomotic communication providing sensory supply to index finger too. 20 Therefore, its routine electrophysiological search is recommended before surgery.…”
