[The sensitive branch of the radial nerve at the inferior third of the forearm and at the wrist. Clinical applications].

Abstract

The sensitive branch of radial nerve is superficial at the inferior third of forearm. This explain frequency of their operative lesions. The purpose of our work is to study his anatomy for choosing surgical approach who protect the nerve. The sensitive radial nerve was dissected is 20 cadaver forearms and wrists. The ride of the nerve and his terminal branches was constant at the lateral side of the radius may be the origins of the terminal branches was variable with 40% of specimens innervating the radial 2 1/2 digits. This is the common terminal distribution of the nerve. The authors do not recommended lateral approach advise anterior surgical approach for the inferior third of the radius to prevent nervous lesions, disagreeable in post-operative period.
