目的 :探讨一种不影响残存神经自行恢复的产瘫臂丛神经修复新方法。 方法 :将上干损伤部位行松解 ,不切除神经瘤 ,将其近端的颈 5或颈 7神经根和神经瘤远端的臂丛上干的神经束膜切开窗口 ,取颈丛皮支或前臂外侧皮神经剪成多段 (一般每段长约 2 .0～ 2 .5 cm ) ,两端分别与颈 5神经根和上干的神经束膜行端侧缝合。 结果 :8例患儿经术后 1～ 11年 (平均 3年 )的随访 ,4例的三角肌和肱二头肌肌力达 4级和 4- 级 ,4例达 3级。 3例后期进行了肩关节松解和旋前圆肌肌腱切断。 结论 :该方法既提供了可使损伤近端颈 5神经根的新生纤维生长至上干的神经通道 ,又未阻断神经瘤内残存神经纤维的自行恢复 ,是治疗产瘫特别是 Tassin 2型的新术式 Objective: To explore a new method of repairing paraplegia brachial plexus without affecting the self-recovery of residual nerve. Methods: The lesion on the dry release line, without excision of the neuroma, the proximal neck 5 or 7 nerve root nerve and neuroma distal brachial plexus on the top of the perineurium incision window, take the rostrum Branch or forearm lateral cutaneous nerve cut into multiple sections (usually each section length of about 2.0 ~ 2.5 cm), both ends of the neck 5 nerve root and the upper end of the peroneal suture line. Results: Eight children were followed up for 1 to 11 years (average 3 years). The strength of deltoid and biceps in 4 cases reached grade 4 and 4, and in 4 cases up to grade 3. 3 cases of shoulder release and pronation in the late rupture of circular muscle tendon. CONCLUSIONS: This method not only provides a nerve channel that allows the growth of nascent fibers that damage the proximal cervical 5 nerve roots to the upper stem, but also does not block the self-recovery of residual nerve fibers within the neuroma, and is a treatment of paralysis, particularly Tassin type 2 New style
