In 21 cadaver dissections the intramuscular anatomy of the musculocutaneous nerve and the relative relationship of the motor and sensory components of this nerve were evaluated. Nearly one half of the fibers entering the musculocutaneous nerve terminate in cutaneous receptors. We report five cases in which biceps reinnervation was performed by a surgical technique that minimizes the period of denervation by using motor nerves (medial pectoral nerves) very close to the biceps muscle. This technique also redirects the cutaneous portion (lateral antebrachial cutaneous nerve) of the musculocutaneous nerve into the biceps muscle to ensure that the motor fibers are not directed toward cutaneous receptors.
在21例尸体解剖中，对肌皮神经的肌内解剖结构以及该神经运动和感觉成分的相对关系进行了评估。进入肌皮神经的纤维中近一半终止于皮肤感受器。我们报告了5例通过一种手术技术进行肱二头肌再支配的病例，该技术通过使用非常靠近肱二头肌的运动神经（胸内侧神经）来尽量缩短失神经支配的时间。该技术还将肌皮神经的皮支部分（前臂外侧皮神经）重新导向肱二头肌，以确保运动纤维不会导向皮肤感受器。
