Case Report on Anatomical Variation of Musculotendinous Slip of Biceps Brachii Muscle

Biceps Brachii muscle is the dominant muscle of the anterior compartment of the arm. The muscle has a two-head origin and is inserted into the rough posterior area of radial tuberosity along with a broad expansion, the bicipital aponeurosis. The biceps brachii muscle is one of the most variable muscles in the body showing variant morphology and attachments. During routine cadaveric dissection we came across a variation on the left side of upper limb. The origin of short head of biceps brachii was in the form of a musculo-tendinous slip. This particular anatomical variation is important for a clinical perspective as it will help in minimizing injury to neurovascular structures and also during repair surgery of proximal biceps tendon rupture.
