目的对比Sextant微创椎弓根螺钉内固定术与传统开放内固定术对老年骨质疏松性脊柱骨折的疗效。方法选取2010年8月至2015年8月收治的80例老年骨质疏松性脊柱骨折患者,随机分为两组,对照组(40例)采用传统开放内固定治疗,观察组(40例)采用Sextant微创椎弓根螺钉内固定治疗,观察并记录两组手术情况、术前术后椎体前缘高度比、Cobb角、日常生活能力量表(ADL)评分及随访6个月期间并发症情况。结果观察组患者手术时间、住院时间均短于对照组,术中出血量、术后引流量均少于对照组(P均<0.05)。术前,两组椎体前缘高度比和Cobb角相比,无统计学差异(P均>0.05)。术后3个月、6个月,两组椎体前缘高度比均较术前明显提高,Cobb角均明显减小(P均<0.05)。但组间椎体前缘高度比、Cobb角比较则无统计学差异(P均>0.05)。术前两组ADL评分相比无统计学差异(P>0.05);术后3个月、6个月两组ADL评分均明显提高(P均<0.05),且观察组ADL评分高于对照组(P均<0.05)。术后随访6个月,两组并发症无统计学差异(P>0.05)。结论 Sextant微创椎弓根螺钉内固定对老年骨质疏松性脊柱骨折具有较好的治疗效果,手术创伤小,患者恢复快。
Objective To compare the curative effect of Sextant minimally invasive pedicle screw internal fixation with open internal fixation on senile osteoporotic spine fractures. Methods Eighty elderly patients with osteoporotic spine fractures admitted from August 2010 to August 2015 were randomly divided into two groups. The control group (40 cases) was treated by open internal fixation. The observation group (40 cases) Sextant minimally invasive pedicle screw fixation was used to observe and record the operation conditions, preoperative and postoperative vertebral anterior height ratio, Cobb angle, ADL score and complications during follow-up 6 months Happening. Results The operation time and hospital stay in the observation group were shorter than those in the control group. The amount of bleeding and postoperative drainage in the observation group were less than those in the control group (all P <0.05). Preoperative, the two groups of vertebral height compared with the Cobb angle, no significant difference (P all> 0.05). At 3 months and 6 months after operation, the anterior vertebral height ratios of both groups were significantly higher than those before operation, and Cobb angles were significantly decreased (all P <0.05). However, there was no significant difference between the anterior vertebral height ratio and Cobb angle (P> 0.05). There was no significant difference in ADL scores between the two groups before surgery (P> 0.05). ADL scores of both groups were significantly increased at 3 months and 6 months after operation (P <0.05), and the ADL score of the observation group was higher than that of the control group (P <0.05). After 6 months of follow-up, the complications of the two groups showed no significant difference (P> 0.05). Conclusion Sextant minimally invasive pedicle screw fixation has a good therapeutic effect on senile osteoporotic spine fractures. The surgical trauma is small and the patients recover quickly.
