[摘要] 目的 比较在椎弓根螺钉固定基础上后路椎体间自体骨融合与Cage融合治疗下腰椎不稳的疗效。 方法 采用随机分组的方法,将2009年1月~2010年6月间本院收治的48例下腰椎不稳的患者分为两组,研究组24例在椎弓根螺钉固定基础上行后路椎体间自体骨融合,对照组24例在椎弓根螺钉固定基础上行后路椎体间Cage融合,比较两组患者的治疗效果。 结果 两组患者出血量、手术时间、住院时间、腰背痛手术评分、并发症发生率和融合率差异无统计学意义(P > 0.05);而研究组椎间隙高度明显低于对照组,差异有统计学意义(P < 0.05)。 结论 后路椎体间自体骨融合与Cage融合一样可作为下腰椎不稳的治疗措施,但缺点是术后椎间隙高度丢失较Cage多。

[Abstract] Objective To compare clinical efficacy of posterior lumbar interbody fusion by using autologous bone or cage for treatment of instability of lower lumbar on the basis of the pedicle screw fixation. Methods By using randomized controlled trail, 48 patients with instability of lower lumbar who stayed and were treated in our hospital were divided into control group (24 cases) and study group (24 cases) from January 2009 to June 2010. Cases in study group were given the therapy of posterior lumbar interbody fusion with autologous bone on the basis of the pedicle screw fixation system, whereas cases in control group were given the therapy of posterior lumbar interbody fusion with cage on the basis of the pedicle screw fixationsystem. Observed and compared the efficacy between two groups. Results The significant difference of blood loss, operative time, hospital stay, JOA score, incidence rate of complication and fusing rate was not founded between two groups (P all > 0.05). The intervertebral space height in study group was significantly lower than that in control group, and there was significant difference between two groups. Conclusion The posterior lumbar interbody fusion can be used for treatment of adult instability of lower lumbar just like cage fusing. But compared with cage fusing, there is significant loss of intervertebral space height.

腰椎不稳主要指腰椎运动节段或脊柱功能单位刚度的下降,使该节段活动范围超过正常、活动性质改变,而引起相应临床表现的一个病理现象。非手术治疗是腰椎不稳症的主要治疗措施,部分患者需手术融合病变节段重建脊柱稳定性和神经根的松解。目前认为椎弓根钉系统内固定加Cage融合是目前治疗腰椎不稳的主要手术方式,但临床工作中笔者发现使用自体骨块行椎间融合亦能达到与Cage融合相似的效果。本研究比较了在椎弓根螺钉固定基础上自体骨融合与Cage融合的临床疗效,旨在为临床治疗决策提供参考。

体骨融合治疗。对照组24例,男17例,女7例,年龄35~79岁,平均(53.97±12.72)岁;退变性不稳13例,峡部裂性滑脱不稳8例,医源性不稳3例;本组患者在椎弓根螺钉固定基础上予以后路椎体间Cage融合治疗。纳入标准:①保守治疗无效;②存在明显的腰椎间盘、椎间关节等退变,并排除其他疾病所引起;③椎体前缘有牵张性骨刺形成或椎间隙明显狭窄,影像学显示椎体移位>4 mm或椎间角变化>10°。两组患者在年龄、性别、病情方面差异无统计学意义(P > 0.05),具有可比性。两组患者均签署知情同意书,该项研究得到本院委员会批准同意。源于:免费论文www.7ctime.com
