椎弓根螺钉内固定骨水泥灌注强化治疗老年腰椎退行性变效果观察

The Effect of Bone Cement Infusion Intensive Treatment of Pedicle Screw Internal Fixation for Elderly Lumbar Degeneration

目的观察椎弓根螺钉内固定骨水泥灌注强化治疗老年腰椎退行性变的效果。方法选取丹东市中心医院2014年1月-2017年1月收治的老年腰椎退行性变患者163例，根据数字表法分为观察组82例和对照组81例。对照组采用单纯椎弓根螺钉内固定，观察组采用椎弓根螺钉内固定骨水泥灌注强化治疗，比较两组患者治疗后腰椎日本骨科协会评估治疗分数（JOA）评分、前凸角和活动度。结果两组治疗3个月后，JOA评分、腰椎前凸角、腰椎活动度之间差异有统计学意义（P〈0．05）。结论骨水泥灌注能够强化椎弓根螺钉的内固定效果，应该在老年腰椎退行性病变的手术内固定中一并使用。

Objective The aim of the study was to evaluate the effect of bone cement infusion intensive treatment of pedicle screw internal fixation for Elderly patients with lumbar degeneration. Methods A total of 163 elderly patients with lumbar degeneration were collected in Dandong Center Hospital from January, 2014 to January, 2017. According to digital table, all patients were divided into observation group （n=82） and control group （n=81）. The patients in observation group were treated with bone cement infusion intensive treatment of pedicle screw internal fixation, while the patients in control group receive simple pedicle screw internal fixation. The postoperative Japanese Orthopedic Association （JOA） scores, lumbar lordosis angles and motion ranges were compared between two groups. Results After 3-months treatment, the JOA scores, lumbar lordosis angles and motion ranges were significantly different between two groups （P〈0.05）. Conclusion The bone cement infusion treatment could intensify the effect of pedicle screw internal fixation, and should apply in internal fixation for elderly lumbar degeneration operation.
