【摘要】 目的探讨空心带侧孔椎弓根螺钉灌注骨水泥强化技术治疗合并老年骨质疏松症胸腰椎爆裂性骨折的临床效果。方法 2011-03-2013-06应用空心带侧孔椎弓根螺钉并灌注骨水泥强化治疗合并老年骨质疏松症胸腰椎爆裂性骨折40例。结果术后疼痛及神经受压症状基本缓解。骨折椎体高度、椎管矢状径恢复满意,未发生伤椎再塌陷,无骨水泥渗漏、脊髓损伤;无螺钉松动、断裂脱出;无腰背痛及功能损失等后遗症状。结论合并老年骨质疏松症胸腰椎爆裂性骨折患者,应用空心带侧孔椎弓根螺钉并灌注骨水泥强化后进行复位固定治疗,既提升了螺钉的把持力又稳定了脊柱,恢复了脊柱矢状和冠状的几何序列,是一种切实可行、相对微创、有效的方法。更多还原

【Abstract】 Objective To explore the clinical effects of treating thoracolumbar burst fracture in the elderly with osteoporosis by hollow pedicle screws with lateral holes implanted with bone cement. Methods The clinical data of 40 cases received the above-mentioned treatment during March 2011-June 2013 were analyzed. Results Pain and nerve compression were almost alleviated. The vertebral height and the sagittal diameter of vertebral canal were satisfactorily restored. Sequela such as re-collapse of the injured vertebral body,leakage of bone cement,damage of spinal cord,loosening,rupture or prolapse of screws,waist and back pain and organ failure were not occurred. Conclusion The tenacity of the screws and the stability of the vertebral column are enhanced,and sagittal and coronal deformities of the vertebral column are corrected in the feasible,effective and minimally invasive surgery on thoracolumbar burst fracture in the elderly with osteoporosis by hollow pedicle screws with lateral holes implanted with bone cement.更多还原
