Anatomical Insight on the Supernumerary Head of Biceps Brachii and its Clinical Relevance - Cadaveric Study.

Abstract

The biceps brachii is as one of the most variable muscle in the human body in terms of number and morphology of its heads. The most frequent variation is the presence of a third head, which has been reported by several authors in different populations. We studied 80 arms of adult formalin fixed cadavers in the Department of Anatomy, B.L.D.E University’s Sri B M Patil Medical College & research centre Bijapur India. The presence of, number of additional heads and their details of attachments were studied. We observed presence of supernumerary heads of biceps brachii in 3 (3.75%) cases, in which one was having unilateral three heads (1.25%) In another case we encountered bilateral incidence (2.50%). Knowledge of occurrence of supernumerary third head of Biceps brachii muscle may become significant for the orthopedic surgeons, traumatologists, plastic surgeons, radiologist, and physiotherapists.
