目的 探讨后路减压固定加椎间 cage融合术治疗腰椎滑脱症的X线、CT及 MRI影像学疗效，为腰椎滑脱的临床治疗 提供依据。方法 对本院2013年6月-2014 年1月收治的腰椎滑脱患者86例进行回顾 性研究，按照临床试验数字随机的方法将 患者分为两组，每组各43例，对照组采用 后路减压固定进行治疗，观察组在对照组 的基础上椎间cage融合术进行治疗，观察 两组患者随访1年后的临床效果和X线、CT 及MRI影像学结果。结果 两组患者均获得 治疗后的12个月的随访，术后随访12个月 后，两组患者治疗后腰部疼痛症状较治 疗前显著改善，且活动受限明显减轻， 但观察组治疗后的优良率为93.02%，与对 照组的90.70%相似，差异无统计学意义， P>0.05；经X线、CT及MRI检查术后两组患 者椎体高度恢复正常，其恢复程度两组相 似，差异无统计学意义，P>0.05，随访 时，经CT检查发现，观察组椎体高度与术 后相似，但观察组较术后有所降低，差异 显著，P<0.05；以CT复查植骨与椎体间有 连续的小骨梁判断为融合良好，观察组43 例患者中术后40例融合良好，融合良好率 为93.02%，对照组43例患者术后39例融合 良好，融合良好率为90.70%，两组患者术 后融合良好率相比，P>0.05。结论 后路 减压固定加椎间cage融合术治疗腰椎滑脱 症临床效果显著，尤其在椎间隙高度恢复 方面要显著优于单纯后路减压固定术，值 得临床推广使用。

Objective To explore the imaging effect of posterior decompression and fixation combined with interbody cage fusion in the treatment of lumbar spondylolisthesis, and to provide the basis for clinical treatment of lumbar spondylolisthesis. Methods Lumbar spondylolisthesis patients of our hospital in June 2013-2014 January 86 cases were retrospectively studied, according to the clinical trials of random number method patients were divided into two groups, each with 43 cases in each group, control group with decompression and internal fixation for treatment, observation group in the control group on the basis of intervertebral fusion cage for treatment observed two groups of patients were followed up for the clinical effect and radiographic results after 1 year. Results Two patients were followed for 12 months after treatment follow-up, postoperative follow-up of 12 months, two groups of patients after treatment of waist pain symptoms significantly improved compared with before treatment, and the limitation of activity was significantly reduced, but the excellent rate of observation group after treatment was 93.02%, and 90.70% in the control group were similar to the difference no statistically significant, P>0.05, the two groups of patients with vertebral height recovery of postoperative CT is normal, the degree of recovery of the two groups were similar, the difference was not statistically significant, P>0.05, were examined by CT, found that the observation group with postoperative vertebral height is similar, but the observation group was decreased significantly after operation, and P<0.05, to review CT interbody bone grafting and continuous bone beam judged as good fusion, 43 patients in observation group, 40 cases of postoperative fusion, fusion rate was 93.02%, the control group of 43 patients in 39 cases after fusion, fusion Good rate was 90.70%, compared two groups of patients with postoperative fusion rate, P>0.05. Conclusion Posterior decompression and interbody fusion in the treatment of lumbar spondylolisthesis with cage clinical effect is remarkable, especially in the vertebral height recovery was significantly better than simple posterior decompression and fixation, it is worthy of clinical use.
