硬膜内松解术治疗胸腰段脊髓陈旧性不完全损伤疗效观察

目的探讨硬膜内松解术在胸腰段脊髓陈旧性不完全损伤治疗中的疗效观察。方法对13例胸腰段脊髓陈旧性不完全损伤的患者行后路硬膜内松解术,其在入院前已经行后路减压椎弓根系统内固定术,术后神经恢复较术前恢复不明显。结果 13例患者随访12~24个月,平均18个月。硬模内松解术后,患者均有不同程度的改善,ASIA评分由术前的62.5分提高到78.6分。按照Frankel脊髓损伤分级,末次随访时患者均较术前脊髓功能明显改善。结论硬膜内松解术在治疗胸腰段脊髓陈旧性不完全损伤中,有助于神经功能恢复,疗效满意。

The clinical observation of the intradural release for the treatment of the old incomplete injury in thoracolumbar spinal cord

Abstract]Objective The clinical observation of the intradural release for the treatment of the chronic incomplete injury in thoracolumbar spinal cord. Methods A total of 13 patients with the chronic incomplete injury in thoracolumbar spinal cord were performed the posterior intradural release. Before admission, all patients were treated with decompression and internal fixation with posterior pedicle system and the neurological recovery was not obvious. Results All the patients were followed up for 12 to 24 months, and the average was 18 months. All patients obtained varied recovery of neurofunction after the intradural release, with ASIA motor scores increasing from average 62.5 point before telease to 78.6 afte the operation, According the Frankel classification of spinal cord injury, the spinal cord function was improved significantly at the end of the follow-up patients. Conclusion The intradural release for the treatment of the chronic incomplete injury in thoracolumbar spinal cord is helpful for the neurological function recovery.
