摘要:

文题释义:
矢状面平衡:矢状面上颈椎、胸椎、腰椎及骨盆相互排列,密切连接,使人体在不借助外力的情况下以最小的能耗保持平衡稳定的姿势,减少站立或运动时对脊柱及脊髓的冲击和震荡,从而良好地适应各种应力状态。腰椎作为脊柱和骨盆的连接部位,在维持躯干整体矢状面平衡方面起着核心作用。
经皮球囊扩张椎体后凸成形:是治疗脊柱压缩性骨折的常用方式之一,不仅能够缓解疼痛、有效强化椎体强度、促进患者早日下床活动,并且还能改善压缩椎体的高度,矫正椎体后凸畸形,改善患者的矢状面序列。

背景:近年来,部分学者认为经皮球囊扩张椎体后凸成形术后继发邻椎骨折可能与腰椎骨盆序列改变引起的矢状面失衡有关。
目的:探讨腰椎骨盆矢状面参数对骨质疏松性腰椎压缩骨折患者行经皮球囊扩张椎体后凸成形术后继发相邻椎体骨折的影响。
方法:回顾性分析2017年1月至2019年1月徐州医科大学附属医院收治的单节段骨质疏松性腰椎压缩骨折患者67例的病历资料,所有患者均接受经皮球囊扩张椎体后凸成形治疗,其中术后继发邻椎骨折32例,未继发椎体骨折35例。根据术后拍摄的腰椎正、侧位X射线片,对比继发邻椎骨折组与未继发椎体骨折组的腰椎前凸角、骨盆入射角、骨盆倾斜角、骶骨倾斜角、骶骨骨盆角、骶骨骨盆后角,同时分析继发邻椎骨折组腰椎参数与骨盆参数之间的相关性。试验获得徐州医科大学附属医院伦理委员会批准。
结果与结论:①两组均获得1年以上的随访;②继发邻椎骨折组的腰椎前凸角、骨盆入射角、骶骨倾斜角、骶骨骨盆角、骶骨骨盆后角均小于对照组(P < 0.05),两组的骨盆倾斜角比较差异无显著性意义(P > 0.05);③Pearson相关分析显示,腰椎前凸角与骨盆入射角、骶骨骨盆角及骶骨骨盆后角有相关性(P < 0.01),与骨盆倾斜角、骶骨倾斜角无相关性(P > 0.05);④结果表明,较小的腰椎前凸角、骶骨倾斜角可增加单节段骨质疏松性腰椎压缩骨折患者行经皮球囊扩张椎体后凸成形术后继发邻椎骨折的风险,较大的骨盆入射角、骶骨骨盆角和骶骨骨盆后角是单节段骨质疏松性腰椎压缩骨折患者行经皮球囊扩张椎体后凸成形术后继发邻椎骨折的保护性因素。

Abstract: BACKGROUND: In recent years, some scholars consider that the secondary adjacent vertebral fracture after percutaneous kyphoplasty may be related to the sagittal imbalance caused by changes in lumbopelvic alignment.   
OBJECTIVE: To explore the effect of lumbopelvic sagittal parameters on secondary adjacent vertebral fracture after percutaneous kyphoplasty in patients with lumbar osteoporotic vertebral compression fracture. 
METHODS: The clinical data of 67 patients with single segmental lumbar osteoporotic vertebral compression fractures who had undergone percutaneous kyphoplasty from January 2017 to January 2019 at the Affiliated Hospital of Xuzhou Medical University were recruited for retrospectively analysis. Of them, 32 patients suffered from secondary adjacent vertebral fracture, and 35 patients did not suffer from secondary vertebral fracture. The lumbar lordosis, pelvic incidence, pelvic tilt, sacral slope, sacrum pubic incidence and sacrum pubic posterior angle were compared between the secondary group and non-secondarygroup according to the postoperative lumbar posteroanterior and lateral radiographs, and the correlation between lumbar parameter and pelvic parameter in the secondary group was also analyzed. The study was approved by Ethics Committee of the Affiliated Hospital of Xuzhou Medical University. 
RESULTS AND CONCLUSION: (1) Both groups were followed up for more than 1 year. (2) The lumbar lordosis, pelvic incidence, sacral slope, sacrum pubic incidence and sacrum pubic posterior angle in the secondary group were less than those in the non-secondary group (P < 0.05). There was no significant difference in pelvic tilt between the two groups (P > 0.05). (3) Pearson correlation analysis showed that lumbar lordosis was correlated with pelvic incidence, sacrum pubic incidence and sacrum pubic posterior angle (P < 0.01), but was not related to pelvic tilt and sacral slope (P > 0.05). (4) The results showed that smaller lumbar lordosis and sacral slope can increase the risk of secondary adjacent vertebral fracture after percutaneous kyphoplasty in patients with single segmental lumbar osteoporotic vertebral compression fractures. The larger pelvic incidence, sacrum pubic incidence, and sacrum pubic posterior angle are protective factors against secondary adjacent vertebral fracture after percutaneous kyphoplasty in patients with single segmental lumbar osteoporotic vertebral compression fractures.
