Introduction Functions of supination and flexion of the forearm and the origin of biceps brachii (BB) muscle by its two heads indicates separate role of each head. A detailed study of morphology of BB can throw light on this interesting observation. Methods In the present study, fifty cadaveric upper limbs (26 right and 24 left) were dissected. Tendons of the two heads were separated up to their insertion. Results Long head (LH) and short head (SH) were separated by a septum of loose areolar tissue in greater part of their length. Medial fibres of the SH contributed to the bicipital aponeurosis. Below the middle of the arm a thin tendon projected laterally from the posterolateral edge of SH, where some fibres of LH were seen inserting. The average length of distal biceps tendon (BT) was 7.56 cm on right and 7.64 cm on left. The width of BT was found to increase gradually towards its insertion. Above the elbow tendons were placed parallel to each other, that of LH being lateral and SH medial. Crossing the bend of the elbow twisting of fibres was observed so that SH was anterior to the LH tendon. At its insertion, SH tendon was distal to LH tendon and prolonged slightly beyond the radial tuberosity. A well defined inverted ‘J’ shaped bursa was found at the insertion. Discussion This morphological description helps in proper appreciation of the functions of Biceps brachii and may be helpful to the surgeons in the repair of ruptured BT. |
