Twenty-one patients with complete brachial plexus palsy due to the avulsion of multiple cervical nerve roots underwent motor and sensory reconstruction. Of these, 15 patients who had been followed for at least 2 years were included in the present study. Sensory reconstruction was performed by nerve graft or nerve crossing to the median nerve. The donor nerves included the supraclavicular nerve in 10 patients, the intercostal nerve in 3, and the C5 nerve root in the first 2 patients. Limited sensibility in the median nerve distribution of the hand was restored in 12 patients, and the results were classified as S2+ in 2, S2 in 4, S1 in 6, and S0 in 3, according to the S0 to S4 grading system. No moving two-point discrimination was restored in any case. While the best recovery obtained was only at the S2+ level, even this limited sensibility was useful for otherwise completely anesthetic patients.
21例因多根颈神经根撕脱导致完全性臂丛神经麻痹的患者接受了运动和感觉重建。其中，15例随访至少2年的患者纳入本研究。感觉重建通过神经移植或神经交叉至正中神经进行。供体神经包括10例患者的锁骨上神经、3例患者的肋间神经以及前2例患者的C5神经根。12例患者手部正中神经分布区域的感觉得到有限恢复，根据S0至S4分级系统，2例结果为S2+，4例为S2，6例为S1，3例为S0。所有病例均未恢复可活动的两点辨别觉。虽然获得的最佳恢复仅达到S2+水平，但即使这种有限的感觉对于原本完全麻醉的患者也是有用的。
