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

•AIN concerning the surgically relevant landmarks such as bi-epicondylar line, pronator teres (PT) were explored.•The AIN originated at a mean distance of 41.56 mm from the bi-epicondylar line.•It was observed that the muscular branches for FDP were shorter than those for FPL.•The muscular branches of AIN had a variable pattern of innervation.•The branches to FPL and FDP would aid as a source of nerve grafting and nerve transfer surgeries.
