摘要
目的 证实同侧选择性颈 7神经根移位术治疗臂丛上干撕脱伤的科学性、可行性与实用性。方法 1996年 3月至 1997年 2月 ,运用同侧颈 7神经根选择性束组移位术治疗臂丛根性撕脱伤 8例。其中 ,上干撕脱伤 7例 ,上干根性撕脱伤合并颈 7神经根部分损伤 1例。选择颈 7神经根前股或前股前外侧份行移位术 ,直接与上干前股作显微缝合。 5例术后随访 6个月 ,3例因时间短未统计在内。结果 8例移位后同侧颈 7神经根支配的肌肉均未见明显的功能障碍。颈7神经根前股外侧份移位至上干前股的 5例 ,4例术后 4个月肱二头肌已恢复屈肘动作 ,疗效显著。 1例合并颈7神经根部分损伤患者的功能恢复欠佳。结论 同侧选择性颈 7神经根纤维束组移位 ,提供了治疗臂丛根性撕脱伤新的动力神经源 。
Objective To verify the rationality, reliability and practicability of ipsilateral selective C 7 transfer for treatment of upper trunk avulsion. Methods Selective ipsilateral C 7 transfer was carried out in 8 patients from March 1996 to February 1997. 7 cases were upper trunk avulsion, the other had left upper trunk avulsion combined with partial injury of the middle trunk. Selective transfer of the anterior division or the anteriolateral part of the anterior division of the ipsilateral C 7 to the anterior division of the upper trunk was done under general anesthesia. 5 of 8 cases were followed up for 6 months. Results The function of the C 7 innervated muscles was not jeopardized in all 8 cases. In these five cases, obvious recovery was observed in 4 cases after transfer of the anteriolateral part of C 7 anterior division to the upper trunk. Electromyographic examination showed nerve regeneration at postoperative month two. Detectable elbow flexion by biceps contraction was found in the fourth postoperative month. The case with combined partial C 7 root injury had a poor result. Conclusions Selective ipsilateral C 7 transfer led to functional restoration of the reinnervated muscles without affecting the function of C 7 innervated muscles. It was therefore a practicable new surgical procedure.
