Extension of the elbow is required to oppose gravity; however, activation of the triceps brachii is frequently underestimated during the surgical planning for brachial plexus injuries. This report aims to describe a novel technique of distal nerve transfer designed for elbow extension reconstruction in patients sustaining a C5-C7 nerve root injury. We report a patient sustaining a brachial plexus injury with triceps palsy and preserved finger extension motion; after careful intraneural dissection of the radial nerve, a fascicle innervating the extensor digitorum communis muscle was sectioned, derouted and connected to a motor branch to the lateral head of the triceps. Eleven months after surgery, elbow extension strength scored MRC M4. No deficits on finger extension were observed.
为了对抗重力，需要伸展肘部；然而，在臂丛神经损伤的手术规划中，经常低估肱三头肌的激活作用。本报告旨在描述一种用于重建 C5-C7 神经根损伤患者的肘部伸展的新型远端神经转移技术。我们报告了一位患有臂丛神经损伤伴肱三头肌无力且手指伸展运动保留的患者；在仔细的桡神经内解剖后，一个支配伸指总肌的束被切断、改道并连接到肱三头肌外侧头的运动支上。手术后 11 个月，肘部伸展力量评分为 MRC M4。未观察到手指伸展的缺陷。
