Abstract Background and aims : Disorders of the peripheral nervous system are common among which entrapment neuropathies are frequently encountered by the clinician. The knowledge of innervation pattern of median nerve to pronator teres are of considerable importance in understanding the various presentations of pronator teres syndrome, in investigating the lesions of median nerve, to plan adequate treatment and to avoid iatrogenic injuries during surgeries there by increasing the perfection of surgical approach. The aim of present study is to study the point of origin of muscular branches of median nerve to pronator teres muscle with respect to interepicondylar line and to study the number of branches of median nerve to the pronator teres muscle. Materials and methods : Fifty upper limbs procured from embalmed cadavers aged about 20 to 50 years were used for the study. Results : Out of total 50 specimens, nerve to pronator teres was arising at a mean distance of 1.31 ± 0.58 cm proximal to the interepicondylar line (range 0.5 - 3cm) and 1.2 ± 1.27 cm distal to the interepicondylar line (0-3.5cm). Conclusion: In greater number of the specimens, the nerve to the pronator teres was arising from the median nerve proximal to the interepicondylar line. In majority of the specimens the pronator teres was innervated by either single branch or two branches.

ABSTRACTThe musculocutaneous nerve usually branches out from the lateral cord of brachial plexus. It innervates the corcobrachialis, biceps brachii and brachialis muscles and continues as the lateral cutaneous nerve of forearm without exhibiting any communication with the median nerve or any other nerve. We report unilateral variation in motor innervations of the left arm in a 58-year-old male cadaver. The musculocutaneous nerve was found to be absent. A muscular branch of the median nerve was supplying the coracobrachialis muscle. In the middle of arm, the median nerve was found to be branching out, bifurcating and supplying the long and short head of biceps. The median nerve was found to be giving a separate branch, which supplied the brachialis muscle and continued as the lateral cutaneous nerve of forearm. The right sided structures were found to be normal. Surgeons should keep such variations in mind while performing arm surgeries.

Abstract Background & aims: The carpal tunnel, located on the palmar surface of the wrist, is a common site of median nerve compression. The median nerve, on passing through the carpal tunnel, divides into lateral and medial branches. The lateral branch then gives off proper palmar digital branches to the thumb and the radial aspect of the index finger, and a recurrent muscular branch to the thenar muscles. The recurrent muscular branch shows different types of variations of the median nerve. Also, there are other variations of the median nerve in the carpal tunnel. These variations greatly influence the symptoms, as well as the treatment of the carpal tunnel syndrome. So, the present work is carried out to study the variations of branching patterns of median nerve in the carpal tunnel. Materials and methods: 40 wrists [20 right and 20 left] from 20 formaldehyde fixed human perinatal fetuses of 34 - 38 weeks of gestation were dissected in the Department of Anatomy, Gauhati Medical College and Hospital, Guwahati. Due ethical clearance was obtained from the Institutional Ethical Committee, Gauhati Medical College and Hospital, Guwahati. Results: In the present study, 24 [66.7%] hands [11 right and 13 left] showed extraligamentous and 12 [33.3%] hands [8 right and 4 left] showed transligamentous variety of thenar branch of median nerve. Also, 4 [10%] hands showed accessory thenar branch of median nerve, all of which took origin within the flexor retinaculum. The comparisons of numbers of variations of thenar branch of median nerve between right and left hands were found to be statistically non significant [P > 0.05]. Conclusion: A detailed knowledge of the median nerve variations in the carpal tunnel is required for successful diagnosis and treatment of the carpal tunnel syndrome and its complications.

ABSTRACTWe present a 62-year-old female patient who had an anatomic variation in the median nerve of the left hand. During surgery for releasing the left carpal tunnel, an abnormally high level of origin of the thenar muscular branch of the median nerve was detected, at 2.5 cm above the proximal border of transverse carpal ligament. It traveled between the medial side of the flexor carpi radialis tendon and median nerve and entered the carpal tunnel. After exiting the carpal tunnel distally, the nerve, was noted to course towards the thenar area. Such variations in the median nerve should be kept in mind while performing carpal tunnel release.
