【摘要】
目的对比颈前路脊髓减压后应用钉板系统与零切迹椎间融合器(Zero—P)治疗脊髓型颈椎病的临床效
韧带骨化的患者,其手术适应证相对较窄。4。
纳入标准:①患者存在渐进性四肢感觉、运动 或括约肌功能障碍等典型脊髓受压症状n41;②年龄 20---75岁;③影像学检查(MRI、CT、X线)证实存在颈 脊髓压迫,为单节段或双节段,病变位于C¨-C。m 排除标准:①既往有颈椎手术史;②存在全身 或局部感染、骨质疏松等影响手术的因素。
二、一般资料
白2010年10月至2013年5月,共纳入47例 CSM患者,随机分为钉板组(颈前路椎问盘切除脊 髓减压后,采用融合器植入、钉板系统内固定术,26 例)和零切迹组(颈前路椎间盘切除脊髓减压后,采 用Zero—P行椎问固定融合术,21例),进行随机对照
