Seventy patients with thoracrolumbar vertebrate fractures were treated by short-segment pedicle screw fixation and were randomly divided into two groups. Fractures in group A （n=20） were rein-forced with posterior morselized bone grafting in vertebrae for spinal fusion, while patients group B （n=50） did not receive the morselized bone grafting for bone fusion. The two groups were compared in terms of kyphotic deformity, anterior vertebral height, instrument failure and neurological functions after the treatment. Frankel grading system was used for the evaluation of neurological evaluation and Denis scoring scale was employed for pain assessment. The results showed that the kyphosis correction was achieved in both group A and group B （group A： 6.4 degree; group B： 5.4 degree）/At the end of follow-up, kyphosis correction was maintained in group A but lost in group B （P=0.0001）. Postoperatively, greater anterior height was achieved in group A than in group B （P〈0.01）. During follow-up study, anterior vertebral height was maintained only in Group A （P〈0.001）. Both group A and group B showed good Denis pain scores （P1 and P2） but group A outdid group B in terms of control of severe and constant pain （P4 and P5）. By Frankel criteria, the changes in neurological functions in group A was better than those of group B （P〈0.001）. It is concluded that reinforcement of short-segment pedicle fixation with morselized bone grafting for the treatment of patients with thoracolumbar vertebrae fracture could achieve and maintain kyphosis correction, and it may also increase and maintain anterior vertebral height. Morselized bone grafting in vertebrae offers immediate spinal stability in patients with th展开更多

文摘目的:移位的跟骨关节内骨折是跟骨骨折最常见的类型。目前常用的为空心钉与钢板内固定两种术式,但其疗效差异尚不清楚。因此,文章对比经皮空心钉与钢板内固定对跟骨关节内骨折的修复效果。方法:计算机检索PubMed,Cochrane Library,Embase,Web of Science和中国知网数据库中关于空心螺钉与切开复位钢板内固定对跟骨骨折治疗效果的随机对照试验研究,检索时限为建库至2019年12月。按入选与排除标准筛选文献,逐一评价纳入研究的质量,提取有效结果数据,采用RevMan 5.3软件进行Meta分析。结果:共纳入15篇随机对照研究,跟骨骨折患者总计1438例,对纳入的文献进行风险偏倚评价,结果显示整体文献质量为中等偏上。Meta分析结果显示:①钢板内固定组在术后Bohler’s角(MD=0.69,95%CI:0.27-1.10,P=0.001)、术后Gissane’s角(MD=0.95,95%CI:0.16-1.74,P=0.02)方面显著优于空心钉固定组(P<0.05);②空心钉固定组在手术时间(MD=-23.92,95%CI:-25.40至-22.44,P<0.00001),术后并发症(OR=0.28,95%CI:0.19-0.41,P<0.00001)方面少于钢板内固定组(P<0.05);③但两组在跟骨高度(MD=0.43,95%CI:-0.17-1.03,P=0.16),术后AOFAS评分(MD=0.61,95%CI:-0.35-1.58,P=0.21)方面差异无显著性意义。结论:上述数据说明钢板内固定修复的跟骨骨折患者术后Bohler’s角及Gissane’s角优于空心钉固定组,但空心钉内固定技术具有手术时间短、并发症发生率低等优点。
