The Muscular Axillary Arch In Relation To The Formation Of Posterior Cord of Brachial plexus - A Case Report

Dr Raghavendra D R, Dr Muralidhar P Shepur, Dr Nirmala D

Abstract :

The muscular axillary arch is a musculotendinous structure that arises from the latissimus dorsi muscle and cross the axilla before inserting in to the humerus, achial fascia or coracoid process. The presence of an axillary arch muscle, the muscular slips arising from the latissimus dorsi or pectoralis major and inserting in to various sites , is reported by various authors. During routine dissection for 1st M.B.B.S. Students in the Department of Anatomy, JJMMC, Davangere, we found this variation in a male cadaver aged 45–50 years. The muscular axillary arch was present on left side arising from latissimus dorsi muscle inserting in to the coracoachialis muscle. It passes between the two divisions of formation of posterior cord of Brachial plexus. Compression by the axillary arch may leads to nerve injury
