Abstract:
Biceps brachii is one of the muscle of anterior compartment
of arm. Various types of variations has been associated
with its proximal attachments. We found an additional third
head of biceps brachii in left upper limb. Variations in
arterial pattern of upper limb have been noted in literature.
We observed that brachial artery gave its terminal
branches in the upper third of the left arm. Near the elbow
the tendon of third head bifurcated through which the radial
artery emerged to enter the forearm taking a superficial
course, whereas the ulnar artery passed deep to the
tendon of third head. So, we are reporting a rare case
wherein variations in the musculature and vasculature of
the upper limb co-existed. The present report attempts to
highlight the clinical significance of such multiple variations
which might be helpful for vascular and reconstructive
surgeons, traumatologists, orthopaedicians operating in
the region of upper limb, to avoid any catastrophic
outcomes. It is also helpful during evaluation of
angiographic images
