Introduction:
The variations in the flexor muscles of the arm, especially the biceps brachii, are very common. The biceps brachii sometimes shows accessory or supernumerary heads which are attached to different parts of the arm. The presence of an accessory head may affect the branching course of the musculocutaneous nerve. This knowledge may be helpful during surgery of the upper limb. This study was undertaken to find out the incidence of these accessory or supernumerary heads of the biceps brachii in an Indian population from the north of Maharashtra.
Materials and method:
The present study was carried out in the Department of Anatomy, Dr. Ulhas Patil Medical College and Hospital, Jalgaon (Kh), (M.S.) The arms of 40 cadavers (right (Rt.)- 40, left (Lt.) -40) were carefully dissected to study the accessory heads of the biceps brachii.
Results:
Out of the 80 arms, 3 had the accessory head of the biceps brachii, which were attached proximally to the humerus, just below the distal attachment of the coracobrachialis. We found a bilateral supernumerary head of the biceps brachii in one cadaver and a unilateral one in another one, which was on the right side. The findings of present study were compared with those of previous studies.
