摘要目的 分析采用单开门椎板成形术治疗过伸位K线(+)颈椎后纵韧带骨化症(ossification of the posterior longitudinal ligament,OPLL)的疗效。方法 2014年5月至2017年5月,共73例颈椎标准位K线(-),而过伸位K线(+)患者在我科采用单开门椎板成形术治疗,其中男44例,女29例;年龄51~72岁,平均57.3岁。病变节段:C3~627例,C3~724例,C4~722例,椎管占位率30%~69%,平均58.9%。结果 73例患者均获得随访,随访时间12~36个月,平均24.3个月。患者JOA评分由术前10~14分(平均11.9分)提高到末次随访时13~17分(平均15.7分),P=0.000。恢复率为66.8%~85.7%,平均74.5%。结论 对于颈椎标准位K线(-),而颈椎过伸位K线(+)OPLL患者,单开门椎板成形术是一种安全有效的治疗方法。
