中文摘要:

  目的：探讨胸椎间盘突出症的手术治疗办法及疗效．．方法：29例胸椎间盘突出症患者，术前均有不同程度的感觉及／或运动障碍．合并后纵切带骨化者16例，合并黄韧带骨化和肥厚者13例。病变部位主要在下胸段(68.3％)．上胸段次之(19．5％)，中胸段最少(12．2％)。采用后路全椎板截骨、经一侧或两侧关节突和下位横突进入切除突出椎间盘、椎板再植椎管成形术，共切除突出椎侧盘41个，9例加用后路椎间植骨融合钉棒系统内同定结果：5例出现片发症，其中运动障碍加重2例，脑脊液漏3例。所有患者术后即有感觉恢复，运动功能6个月以内恢复较快，24个月后无明显恢复。24例患者术后获得随访，随访时间7～62个月，平均19个月。疗效评价参照Epstein标准，优11例．良9例，改善2例，差2例，优良率83.33％，总有效率91．67％。术后CT及MRI显示椎板融合成形良好，手术减压满意。结论：胸椎间盘突出症发病部位以下胸段为多．如出现症状多需手术治疗，切除突出的椎间盘可获得满意疗效。
