摘要
目的探索Bryan颈椎间盘假体应用于亚洲人的手术操作要点和早期治疗效果,观察假体植入后的稳定性和植入节段的活动度。方法对8例脊髓型颈椎病患者(10个节段)行颈前路间隙减压,Bryan颈椎间盘假体置换术。手术前和术后3个月进行JOA评分,术后3个月进行Odom评级,评价早期治疗效果;术后1周、3个月摄置换节段前屈后伸位,左右侧屈位X线片,观察稳定性和植入节段的活动度。术后3个月进行置换间隙CT或MRI扫描,进一步确定假体位置和置换部位是否存在早期的异位骨化现象。结果本组患者全部经过至少3个月(平均36个月)的随访,术后患者症状明显缓解、脊髓功能改善,JOA评分由术前平均88(7~12)上升至术后平均158(13~17)。8例患者术后3个月置换节段前屈后伸活动范围平均475°(38~58°);左右侧屈活动范围分别为平均338°(23~44°),和313°(25~41°)。未发现偏移或假体下沉。CT或MRI扫描显示7个节段的假体上、下金属壳位于临近下、上终板骨的中央,1个节段假体偏离<2mm,1个节段假体偏离>2mm、<4mm。未见假体周围的异位骨化现象。结论颈人工椎间盘置换术保持前路减压的良好效果,同时取得了良好的术后稳定性,保持了颈椎正常的活动度,为颈椎病的治疗提供了一种新的选择。
