ABSTRACT

Background: Anatomical variations in the branching pattern of the brachial plexus have been described in humans by many authors; however these have not been extensively catalogued. The aim of the study was to describe and observed anomalies in distribution of the branch (branching pattern) derived from the cord of brachial plexus, both in its supraclavicular and infraclavicular parts.

Methods: This study included thorough dissection of 60 brachial plexuses which belonged to 30 cadavers (male: female ratio = 28:02 ) with age range of 20-60 years, obtained from the Department of Anatomy, College of Medical Sciences (CMS-TH), following standard guidelines.

Results: Out of 60 limbs dissected in present study, Normal branching pattern of the posterior cord was encountered in 52 (86.67%) limbs, the remaining 8 (13.33%) being variants in one form or the other. The upper subscapular nerve, the thoracodorsal nerve, the lower subscapular nerve and the axillary nerve were found to arise normally in 91.66%, 96.66%, 96.66% and 98.33% of the limbs respectively.

Conclusion: The present study carried out on adult human cadavers revealed some rare variations in the branching pattern of the brachial plexus. These variations are of clinical significance are very useful for the anatomists, radiologists, anesthesiologists, neurosurgeons and orthopedic surgeons and general surgeons.

Key words: Brachial plexus, branching pattern, Anatomical variation.
