The intention of this prospective study was to evaluate the role of the musculocutaneous and radial nerves in elbow flexion and forearm supination. The study included 29 patients having loco-regional anaesthesia for minor hand surgery. Elbow flexion and forearm supination forces were evaluated before and after an isolated musculocutaneous nerve block in one group and an isolated radial nerve block in another group. The results showed that the biceps tendon is responsible for 47% of the forearm supination force and the combination of brachioradialis and the supinator for 64% of this force. It showed also that the musculocutaneous and radial nerves contribute by 42% and 27.5%, respectively, to the flexion force of the elbow. These results are intended to help surgeons in decision making when treating chronic biceps tendon rupture, in repair of traumatic brachial plexus neuropathy and in using tendon transfers, such as the Steindler transfer, around the elbow.
这项前瞻性研究的目的是评估肌皮神经和桡神经在屈肘和前臂旋后动作中的作用。该研究纳入了29例因手部小手术接受局部麻醉的患者。一组在单独进行肌皮神经阻滞前后以及另一组在单独进行桡神经阻滞前后，分别评估了屈肘力和前臂旋后力。结果显示，肱二头肌肌腱在前臂旋后力中占47%，肱桡肌和旋后肌共同作用占该力的64%。研究还表明，肌皮神经和桡神经分别对屈肘力贡献42%和27.5%。这些结果旨在帮助外科医生在治疗慢性肱二头肌肌腱断裂、修复创伤性臂丛神经病变以及在肘部周围使用肌腱转位术（如施泰德勒转位术）时做出决策。
