Locating the anterior interosseous nerve in relation to the surgically relevant landmarks of the forearm: A cadaveric study.

ABSTRACT:

Background

This study emphasizes locating the anterior interosseous nerve (AIN) related to its level of origin, number, and lengths of its muscular branches and relation to surgically important landmarks such as the bi-epicondylar line, pronator teres, and Gantzer muscles.

Methods

The study was undertaken at a private Medical school in south India during 2019-20. The level of origin of AIN was measured from the bi-epicondylar line and its length was measured up to the upper border of the pronator quadratus using 44 cadaveric upper limbs. The number of branches given to flexor digitorum profundus (FDP) and flexor pollicis longus (FPL) was quantified and their lengths were measured.

Results

The nerve originated at a mean distance of 41.56 mm from the bi-epicondylar line
