ABSTRACTDuring dissection of a 55-year-old female cadaver, we observed that three nerve roots contributed to the formation of Median nerve in her right upper limb. Along with this variation, absence of Musculocutaneous nerve was noticed. The muscles of front of arm i.e. Biceps Brachii, Brachialis and Coracobrachialis received their nerve supply from Median nerve. The Lateral cutaneous nerve of forearm was derived from Median nerve. Also an accessory head of Biceps Brachii muscle was present in the right arm of the same cadaver. It is extremely important to be aware of these variations while planning a surgery in the region of axilla or arm as these nerves are more liable to be injured during operations.

Indirect Injury

The musculocutaneous nerve is rarely injured because it is short and is located deep in the shoulder and arm. Damage is usually caused by direct injuries, including stabbing, explosion, and surgery in a war setting. Although indirect injury of the musculocutaneous nerve is extremely rare, it occurs in various situations. In military parachuting-related activities, musculoskeletal injury occurs most commonly, and static line injury is known as rupture of the biceps brachii tendon. However, musculocutaneous neuropathy can also result from secondary injury by the static line. The musculocutaneous nerve goes together with the biceps brachii muscle, and the musculocutaneous nerve could overstretch and compress within the coracobrachialis muscle where the nerve is relatively fixed due to the overloading of the upper arm with shoulder extension. This report focuses on the indirect musculocutaneous nerve injury with axonotmesis following an overloading event by the static line during military parachuting. In this case, some physicians may confuse nerve injury with static line injury, leading to delays in the diagnosis of neuropathy. If the biceps brachii muscle is damaged due to trauma, checking for the accompanying musculocutaneous nerve injury is necessary.

Introduction: Musculocutaneous nerve lesion in a throwing athlete is a rare condition. We report the case of a professional baseball pitcher with an isolated musculocutaneous nerve lesion that occurred during a pitching motion. Case Presentation: The patient had radiating pain in the upper arm and weakness of elbow flexion. Physical examination revealed flaccid paralysis of the biceps brachii muscle and paresthesia in the right lateral forearm. Musculocutaneous nerve injury was suspected. Because some signs of recovery were observed within a few days, the patient received non-operative management. Nerve conduction studies at 2 weeks after the injury showed low-amplitude compound muscle action potential of the right biceps brachii muscle by stimulation of the musculocutaneous nerve. Needle electromyography showed markedly reduced motor unit potential recruitment in the biceps brachii muscle. He was diagnosed as having isolated musculocutaneous nerve injury. At 2 months after the injury, the muscle contraction and strength of the biceps brachii muscle improved. At 7 months after the injury, muscle weakness was fully recovered. His pitching ability returned to that of a competitive player. Conclusion: Because the neuroparalysis was incomplete and began to recover within a few days, we considered the pathology of this injury to be incomplete axonotmesis, which was successfully treated conservatively. Keywords: Isolated musculocutaneous nerve injury, baseball pitcher, axonotmesis.
