Abstract :

During routine classroom dissection, conducted for undergraduate medical students, we encountered, anatomical variation of some lateral fibers of the achialis muscle merges with achioradialis muscle, suggesting the small medial head of the achioradialis muscle associated with communication between musculocutaneous, median and ulnar nerves. Radial nerve passes between these two heads of achioradialis muscle and median nerve at its immergence give communicating anch to ulnar nerve, musculocutaneous nerve also gives communicating anch to median nerve at the level of insertion of coracoachialis muscle. Knowledge regarding presence of radial nerve in between two heads of achioradialis muscle and communications between musculocutaneous, median and ulnar nerves is immense important for radial nerve entrapment for clinicians and axillary surgeons. Possible emyological explanation and clinical importance have been discussed.
