CONTEXT The musculocutaneous nerve is one of the terminal branches of the lateral fasciculus of the brachial plexus, and is responsible for innervation of the flexor musculature of the elbow and for skin sensitivity on the lateral surface of the forearm. Its absence has been described previously, but its real prevalence is unknown. CASE REPORT A case of absence of the musculocutaneous nerve t...

The transfer of part of the ulnar nerve to the musculocutaneous nerve, first described by Oberlin, can restore flexion of the elbow following brachial plexus injury. In this study we evaluated the additional benefits and effectiveness of quantitative electrodiagnosis to select a donor fascicle. Eight patients who had undergone transfer of a simple fascicle of the ulnar nerve to the motor branch...

The Musculocutaneous nerve arises from the lateral cord of the brachial plexus, passes inferiorly and laterally, and then pierces through the coracobrachialis .After supplying it descends between the biceps and the brachialis, giving branches to both the muscles and continues as the lateral cutaneous nerve of the forearm. Variations in the origin, course, branching pattern, termination and conn...

BACKGROUND Root avulsion to all 5 roots of the brachial plexus is a common presentation and keeps a major reconstructive challenge. The contralateral C7 (CC7) nerve transfer has been used in treating brachial plexus avulsion injury (BPAI) since 1986. However, the effectiveness of the procedure remains a subject of controversy. The aim of this meta-analysis was to study surgical outcomes regardi...

BACKGROUND Infraclaviculr Brachial plexus (ICBP) block is useful for upper extremity surgery. The aim of this study was to compare the ultrasound (US) technique with the nerve stimulation (NS) technique in their success rates and times to perform ICBP block. METHODS 60 patients undergoing surgery of the upper limb were randomly allocated into two groups (n = 30 per group). Group 1; US, and Gr...

Anatomical variations of peripheral nerves constitute a potentially important clinical and surgical issue. The aim of this work is to study the variations of the median nerve in the arm with respect to its branching pattern and distribution as well as its possible communication with the musculocutaneous and/or ulnar nerves. Sixty arms pertaining to 30 preserved human cadavers, ranging in age fr...

The median nerve is usually formed just lateral to the third part of the axillary artery by the union of its medial and lateral roots coming from medial and lateral cords of the brachial plexus respectively. It then descends down in the front of the arm and crosses superficial to the brachial artery from lateral to medial side. It enters the cubital fossa along with the brachial artery. Normall...

Brachialis muscle anatomy and its innervation has been studied previously by many authors. There have been inconsistent description of the brachialis muscle anatomy in literature. In the present study 40 upper limbs of twenty embalmed Indian cadavers were dissected and found that all specimens of the brachialis had 2 heads, superficial and deep. The larger, superficial head had more proximal or...

Purpose: To investigate the impact of shoulder subluxation (SS) on peripheral nerve conduction and function hemiplegic upper extremity (HUE) in poststroke patients.Methods: Thirty post-stroke patients were selected (SS group: 15 patients, non-SS respectively). Evaluation limbs: compound muscle action potential (CMAP) amplitude latency suprascapular, axillary, musculocutaneous, radial, median, u...
