OBJECTIVE The aim of this study was to analyze the incidence of nerve communication between the musculocutaneous and median nerve . METHODS Anatomical dissection of 40 limbs from 20 fetal cadavers was performed at the Laboratory of Anatomy, Faculdade de Ciências Médicas e da Saúde da Pontifícia Universidade Católica de São Paulo . RESULTS A communicating branch was found in 10 upper limbs. ...

Detailed knowledge of course and distribution of nerves in the axilla and arm is very important in the management of nerve injuries particularly in case of their variations. Bilateral absence of the musculocutaneous nerve was found during routine dissection in a male cadaver. The dissected part was cleared to see the distribution of the muscles of the arm. The muscles of the flexor compartment ...

Postoperative isolated injury of the musculocutaneous nerve is a rare disorder and complication. Reported cases are claimed to present with loss of biceps and brachialis power without neuropathic pain. When injury occurs to one of the terminal branches of the brachial plexus, the lateral cutaneous nerve of the forearm, pain is the major symptom and it typically radiates along the radial aspect ...

We report the results of 15 patients who underwent nerve transfer for restoration of shoulder and elbow function at our institution for traumatic brachial plexus palsy. We present these results in the context of a meta-analysis of the English literature, designed to quantitatively assess the efficacy of individual nerve transfers for restoration of elbow and shoulder function in a large number ...

Anomalies of the brachial plexus have previously been described in the literature. The coracobrachialis muscle is typically innervated by the musculocutaneous nerve. During a gross anatomy dissection we found that the coracobrachialis muscle was innervated by a branch from the lateral root of the median nerve. Knowledge of the anatomical variations of the peripheral nervous system is important ...

Radial nerve innervation to the brachialis muscle has been studied previously by different authors in Caucasian, Chinese, and Thai population. Present study was aimed to describe the radial nerve and musculocutaneous nerve contribution to the brachialis muscle and to elucidate racial differences between Indian and other populations. Hundred-forty superior extremities of 70 embalmed cadavers inc...

Introduction: The brachial plexus is responsible for the innervation to the upper limb and some parts of the thorax. Variations in the branching of the brachial plexus are common and have been reported in 65.3% of the population. The variations (Atypical communication) of brachial plexus have significant clinical and surgical importance. Methods: In this study 10 upper limbs which belonged...

One of the more commonly reported variations in musculocutaneous and median nerves is a communication between the two. Such communications have been noted in the literature for well over a century, and numerous studies have attempted to quantify their rate of incidence and classify their different patterns. Most communications occur close to the brachial plexus in the proximal arm; communicatio...

We describe an unusual combination of unilateral upper limb variations, including an axillary arch, absence of a "typical" musculocutaneous nerve, direct lateral cord innervation of the muscles usually supplied by the musculocutaneous nerve, variant superficial brachial artery, a high anomalous origin of the common interosseous artery and a superficial ulnar artery noted during routine cadaver ...

The clinical and surgical importance of anatomical knowledge of the musculocutaneous nerve and its variations is due to the fact that one of the complications in many upper-limb surgical procedures involves injury to this nerve. During routine dissection of the right upper limb of a male cadaver, we observed an anatomical variation of this nerve. The musculocutaneous nerve originated in the lat...
