Introduction The musculocutaneous nerve and the median nerve are branches from the lateral cord of the brachial plexus with a root value of C5, C6, and C7. The medial root of the median nerve is a branch of the medial cord. The present study aims at observing any variations in these peripheral nerves, so that this knowledge can be utilized by surgeons, anesthesiologists, and orthopedicians during surgical procedures and nerve block. Materials and Methods The present study was carried on 30 adult embalmed cadavers (60 upper limbs) in the department of anatomy of the Kasturba Medical College , Manipal, India. The infraclavicular part of the brachial plexus was dissected, and any anatomical variations in the formation and in the branching pattern of the musculocutaneous nerve and of the median nerve were noted and photographs were taken. Results The median nerve was noted to be formed from 3 roots in 8 out of 60 dissected upper limbs (13.33%). The musculocutaneous nerve was absent in 5% of the dissected limbs, and communications between these 2 nerves were noted in 13.33% of the dissected limbs. Conclusions Noted variations of the nerves may be of help to surgeons operating in the axillas and in the arms.

Fourth Root

An unusual combination of median nerve’s variations has been encountered in a male cadaver during routine educational dissection. In particular, the median nerve was formed by five roots; three roots originated from the lateral cord of the brachial plexus joined individually the median nerve’s medial root. The latter (fourth) root was united with the lateral (fifth) root of the median nerve forming the median nerve distally in the upper arm and not the axilla as usually. In addition, the median nerve was situated medial to the brachial artery. We review comprehensively the relevant variants, their embryologic development and their potential clinical applications.

Small Branch

The brachial plexus is the most variable part of the peripheral nervous system. The Musculocutaneous nerve is a terminal branch of the lateral cord of the brachial plexus in a normal individual. It is not uncommon for variations in the origin, branching termination, and connection patterns. During routine dissection in the Anatomy Department, College of Medicine, King Saud University, we found the lateral cord after giving a small branch to the coracobrachialis muscle join the medial root of the medial cord to form the median nerve. Knowledge of these variations is essential for anatomists, orthopedics, neurologists, and anesthesiologists.

Male Cadaver

Variation of brachial plexus characterized by the absence of musculocutaneous nerve in right arm was found during routine dissection of a 54 year old male cadaver. After giving lateral pectoral nerve, rest of the lateral cord continued as lateral root of median nerve. An unusual branch was arising from lateral cord which crossed the axillary artery anteriorly and then divided into two branches. One of these branches joined ulnar nerve and other medial root of median nerve. All the muscles of front of arm were supplied by branches of median nerve. These variations are important for the anesthetists, surgeons, neurologists during surgery and for anatomists during dissection in the region of axilla.

Sensory Reconstruction

ABSTRACT Objective: Restoration of the sensitivity to sensory stimuli in complete brachial plexus injury is very important. The objective of our study was to evaluate sensory recovery in brachial plexus surgery using the intercostobrachial nerve (ICBN) as the donor. Methods: Eleven patients underwent sensory reconstruction using the ICBN as a donor to the lateral cord contribution to the median nerve, with a mean follow-up period of 41 months. A protocol evaluation was performed. Results: Four patients perceived the 1-green filament. The 2-blue, 3-purple and 4-red filaments were perceptible in one, two and three patients, respectively. According to Highet's scale, sensation recovered to S3 in two patients, to S2+ in two patients, to S2 in six patients, and S0 in one patient. Conclusion: The procedure using the ICBN as a sensory donor restores good intensity of sensation and shows good results in location of perception in patients with complete brachial plexus avulsion.

Restoration Of Sensibility

ABSTRACT Objective Few donors are available for restoration of sensibility in patients with complete brachial plexus injuries. The objective of our study was to evaluate the anatomical feasibility of using the intercostobrachial nerve (ICBN) as an axon donor to the lateral cord contribution to the median nerve (LCMN). Methods Thirty cadavers were dissected. Data of the ICBN and the LCMN were collected, including diameters, branches and distances. Results The diameters of the ICBN and the LCMN at their point of coaptation were 2.7mm and 3.7mm, respectively. The ICBN originated as a single trunk in 93.3% of the specimens and bifurcated in 73.3%. The distance between the ICBN origin and its point of coaptation to the LCMN was 54mm. All ICBNs had enough extension to reach the LCMN. Conclusion Transfer of the ICBN to the LCMN is anatomically feasible and may be useful for restoring sensation in patients with complete brachial plexus injuries.
