次全椎板减压、单枚Cage联合椎弓根钉内固定术治疗腰椎不稳症

Treatment of Unstable Lumbar Vertebrae by Posterior Lumbar Interbody Fusion with Times Omni-Posterior Decompression and Single Cage

目的评价次全椎板减压、单枚Cage联合椎弓根钉治疗腰椎不稳症的临床疗效。方法选择2008年1月-2011年1月间采用次全椎板减压、单枚Cage联合椎弓根钉内固定治疗的26例腰椎不稳患者进行回顾性研究。26例均为单节段病变,术后定期随访,比较术前及术后相对椎间隙高度,按邱勇所提出的标准观察融合情况。采用JOA及ODI评分进行评估。结果所有患者获随访,术后相对椎间隙高度与术前比较差异有统计学意义(P<0.05);末次随访融合率为100%。JOA评分由术前(6.94±4.03)分上升到末次随访时的(12.13±3.37)分;ODI评分由术前(52.61±6.75)分降至末次随访(6.42±2.39)分。结论次全椎板减压、单枚Cage联合椎弓根钉内固定术是一种治疗腰椎不稳的有效方法。

Objective To evaluate the clinical curative effect of the posterior lumbar interbody fusion with times omni-poste-rior decompression and singl Cage to treat Unstable Lumbar Vertebrae. Methods 26 cases of Unstable Lumbar Vertebrae who had been treated with the posterior lumbar interbody fusion with single Cage, between Jan 2008 and Jan 2011 were retrospectively studied. All cases had single intervertenral space involved, were regular follow-up after operation. Relative vertebral gap height between preoperative and postoperative was compared, intervertebral fusion after operations according to the standard of Qiu Yong was observed. JOA score system and ODI score system were used to evaluate the clinical effects. Results All cases were followed up. Vertebral relative vertebral gap height between preoperative and postoperative follow-up showed remarkable difference （P 〈 0.05 ）. 26 cases obtained fusion with the fusion rat-io of 100%. The JOA score from （ 6.94 ± 4.03 ） preoperative to （ 12.13 ± 3.37）. The ODI score decreased from （52.61 ± 6.75） preoperative to （6.42±2.39） at final follow-up. Conclusion The pos-terior lumbar interbody fusion with times omni-posterior decompression had been found to be an effective technique to treat Unsta-ble Lumbar Vertebrae.
