To determine the potentialities of median nerve motor branches neurotization by the ulnar nerve and vice versa the anatomy of muscular branches of median and ulnar nerves in the forearm was studied in detail. Study was performed on 20 upper extremities from 10 adult cadavers. The number of branches, their length and precise place of divergence from the main trunk were assessed. It was stated that topographic anatomy of muscular branches of the median and ulnar nerves in the forearm was quite invariable. For neuratization from the median nerve the longest branches that passed to pronator teres muscles and superficial flexor muscle of fingers can be used; from the ulnar nerve - long branch to the ulnar flexor muscle of wrist.

Abstract THE ULNAR NERVE is compressed at the cubical notch in patients with cubital tunnel syndrome. To definitively alleviate this compression, the nerve can be transposed under the pronator teres and flexor carpi ulnaris muscles. This procedure is also known as medianization of the ulnar nerve because it then courses parallel to the median nerve. In the current article the procedure is described in a step-by-step fashion.

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.

Number Of Branches

Introduction:The precise knowledge of level of origin of muscular branches of median nerve are essential in free muscular transfers to restore the mobility of fingers after trauma and to understand the various presentations of nerve entrapment. The anatomical knowledge and variations of recurrent nerve is important to prevent the complications during the release of transverse carpal ligament.Aim & Objectives: To study the points of origin of muscular branches with respect to IEL and number of branches to muscles of forearm and also learn the mode of origin of recurrent nerve and its relation to the flexor retinaculum.Subjects and Methods:Dissection 40 upper limbs procured from embalmed cadavers of Dr. VRK Women’s Medical College, Hospital and Research Centre, Hyderabad, for the study.Results:The mean of point of origin of NPT was 1.21 cm proximal and 1.20 cm distal to IEL whereas for NFCR, NPL, NFDS and AIN nerve it was 2.12 cm, cm, 4.54 cm and 3.29 cm distal to IEL respectively. The number of branches to muscles of forearm varied from 1 to 3. The recurrent nerve was arising from lateral and intermediate branches of median nerve in 39 (97.5%) and 1 specimens (6%) respectively. Its relationship with flexor retinaculum was extra ligamentous in 33 specimens (82.5%) and transligamentous in 7 specimens (17.5%). It innervated APB, FPB and OP in 19 specimens (47.5%), only APB, FPB in 16 specimens (45%) and only APB, OP in 3 specimens (7.5%).Conclusion:All the muscular branches of median nerve were arising predominantly distal to IEL except nerve to pronator teres. The number of branches varied from 1 to 3. In majority of the specimens, the recurrent nerve was arising from the lateral terminal branch of median nerve and its relation with flexor retinaculum was extraligamentous.

Developmental Variations

AbstractA case of bilateral high termination of brachial artery was found during a cadaveric dissection at NEIGRIHMS, Meghalaya. The brachial artery of both arms in the upper 113rd divided into supericial and deep branches, the superficial artery was observed anteromedial and the deep artery posteromedial in relation to the median nerve. In the cubital fossa, the deep artery passed beneath the pronator teres muscle to give common interosseous artery which divided into anterior and posterior interosseous branches. The main trunk followed normal ulnar arterial course. In both the arms, the superficial branch of brachial artery remained lateral to the median nerve to reach the cubital fossa where it passed deep to the bicipital aponeurosis and descended just beneath the brachioradials muscle, following the normal course of radial artery. These developmental variations were thoroughly discussed and compared with previously published findings with their clinical importance.
