后椎体

Methods Six cadaveric lumbar vertebrae were harvested and evaluated with dual-energy x-ray absorptiometry and quantitative computed tomography to assess bone mineral density. Matched, polyaxial pedicle screws were then randomly assigned by side and placed using the Magerl, Krag or caudad trajectory technique assisted by Iso-C 3D scan and 3D navigation system. Cyclic loading tests were performed with a maximum 250 N load at 3 Hz up to 30000 cycles while recording load and displacement. Stiffness quotients were calculated it comparison.

从尸体中获取6节腰椎椎体经DEXA和QCT检测骨密度值，证实为骨质疏松后在计算机导航下按随机分组的方法向12个椎弓根中置人不同方向的椎弓根螺钉，使用MTS-858生物力学仪脊柱力学测试平台进行±250N的循环负荷疲劳测试，记录负荷循环中的螺钉位移，计算系统的刚度系数并进行对比分析。

Then some measurements were obtained,such as:①Antero-posterior diameter of the epidural fat located ventrally and dorsally to the dural sac from S_1 to S_5 levels.

测量骶椎各水平前、后硬膜外脂肪的厚度及S1椎体水平椎管、硬膜囊和硬膜外脂肪面积。

There were no fixation failure. Conclusion: Transpedicular intracorporeal grafting combined with GSS-Ⅱ pedicle screw internal fixation could prevent later kyphosis and the bight of vertebra loss

采用经椎弓根植骨加GSS-Ⅱ型椎弓根螺钉系统治疗胸腰椎骨折，可有效地防止后期椎体高度再丢失、后凸角度加大和内固定失败等并发症。

The present findings regarding multisegmental inneration to ertebral bodies may explain the diffuse pain that originates within osteoporotic ertebral fractures in elderly patients.

关于腰椎椎体是由多节段神经支配的研究结果解释了老年患者发生骨质疏松性椎体骨折后为何出现弥散性的疼痛。

Objective: To assess the efficacy of percutaneous kyphoplasty in the treatment to osteoporotic vertebral compression fractures.

目的：探讨经皮椎体后凸成形术治疗骨质疏松性椎体骨折的临床效果。

BACKGROUND: Many clinical studies have demonstrated that pseudoarthrosis formation after thoracolumbar vertebral compression fracture is often assessed using lateral films.

摘要背景：许多临床研究阐述了胸腰椎椎体压缩性骨折后应用常规侧位片来评定是否有假关节形成，作者所查应用仰卧或俯卧侧位X射线片来诊断椎体真空征的文献较少。

Methods 16 cases of thoracolumbar burst fractures with spinal cord or equina cauda injuries were treated with anterior subtotal vertebrectomy, Pyramesh with bone debris intervertebral implantation and Z-plate fixation.

16例胸腰椎爆裂性骨折伴脊髓或马尾损伤患者进行前路椎体次全切除减压，自体碎骨装入Pyramesh钛网后行椎体间植骨，加用Z-plate内固定。

Treatment of spinal tuberculosis1methods between february 1998 and august 2000 , 12 patients with spinal tuberculosis were operated with anterior vertebrectomy , bone grafting and plating1 evaluation including bone fusionrate , correction of deformity and status of spinal lesion was carried out1results in an average of ten months ,spinal tuberculosis was completely cured and solid bone fusion had taken place in all 12 patients1 the time for bone fusion averaged 518 months and the average angle of correction of kyphosis was 16°1conclusions anterior plating following vertebrectomy and bone grafting offers a complete removal of lesion and decompression of the spinal canal as well as reconstruction of spinal stability1 early rehabilitation and an increased curative rate can be expected through this procedure1

目的 探讨经脊柱前路结核病灶清除的同时植骨内固定的可行性和必要性，以及对脊柱结核的治疗效果。方法1998 年2月~2000 年8 月采用脊柱前路病椎切除加植骨，并采用orion或z-plate 钢板进行椎体固定。共治疗12 例脊柱结核，观察植骨融合及矫正畸形情况和结核病灶愈合情况。结果经平均10 个月的随访，12 例患者脊柱结核均治愈，植骨与受骨区全部骨性融合，融合时间平均为518 个月，后凸矫正角度平均16°。全组病例切口均一期愈合。无手术并发症。结论本方法可经脊柱前路作较彻底的病灶清除，并较好地进行脊柱矫形和椎管减压，完成脊柱稳定性重建，有利于患者早期离床活动和脊柱结核治愈率的提高。

Methods:Forty-five patients（62 centrum）whose centrums were fractured took MRI within one day after wound,and separately make a follow-up visit reexamination in 3 months, 6 months, and 9 months.

45例（62个椎体）椎体骨折患者于外伤后1 d内行MRI检查，并分别于3、6、9个月行MRI随访复查。

Objective:To explore the causes and preventive ways of the bone cement leakages in kyphoplasty for osteoporosis compressive fractures.

中文摘要：目的：探讨椎体后突成形术治疗骨质疏松性椎体骨折骨水泥外漏的原因和预防办法。
