INTRODUCTION
Neural variations of the brachium constitute an important anatomical and clinical entity. Although frequently reported, if accompanied by other anomalies, they deserve special mention in anatomical literature. The nerves of the extremities are especially vulnerable to injury because of their long course and superficial distribution.
MATERIAL AND METHODS
The present study has been undertaken on 60 upper limb routine dissections from the year 2013 - 2015. The data collected and compiled.
OBSERVATION AND RESULTS
In the present study out of 60 upper limb dissections, we got 4 variations. The specimen no 20, 37 right upper limbs and specimen 42 & 51 left upper limbs are having the communication between the musculocutaneous nerve and the median nerve. The communication between median and musculocutaneous nerve before piercing the coracobrachialis is seen in one case; the three communications after piercing the coracobrachialis muscle.
SUMMARY & CONCLUSION
Its ontogeny and clinical implications are discussed in detail. A lack of awareness of variations with the different patterns might complicate the surgical repair and may cause ineffective nerve blockade.
