Study of variant relations of median nerve to axillary and brachial artery
Journal Title: Medpulse International Journal of Anatomy - Year 2019, Vol 9, Issue 2
Abstract
Background: The knowledge of anatomical variations in the formation, course and relations of median nerve with nearby structures is important in surgical procedures to avoid injury to either nerve or its nearby structure. Aim and Objective: To know variations in course and relation of median nerve with Axillary and Brachial artery. Material and Methods: The study was carried out at department of Anatomy, Bharati Vidyapeeth (Deemed to be university) Medical College, Sangli on 100 formalin fixed specimens of upper limb from 50 adult human cadavers (irrespective of sex and age 25-70 years). After careful dissection, relations of median nerve with axillary and brachial artery and course of median nerve in arm were noted and recorded. Data was analyzed by Microsoft excel analysis. Observations and Results: In 90% specimens, Median nerve formation commonly occurred in Axilla or upper third of arm whereas in 10% specimens it was formed in relation to brachial artery. In 64 out of 90 specimens median nerve was formed anterior to axillary artery. Median nerve coursed lateral to brachial artery and then crossed it medially in 81 specimens while in 19 it was medial throughout its course in arm. Conclusion: Different anatomical variations of relation and course of median nerve to axillary and brachial artery can be of use to plastic, orthopedic and vascular surgeons
