为了探讨椎体成形术和椎体后凸成形术对邻近椎间盘和椎体的力学影响,本研究将8个脊柱功能单元(T12~L2节段:包括3个椎体和2个椎间盘)分别行中间椎体骨折后,在中间椎体行磷酸钙骨水泥椎体成形术和椎体后凸成形术,并测量骨折前、两种方法成形后的中间椎体及相邻椎体生物力学指标。研究显示,椎体成形术FSU中间椎体成形后整体刚度和强度无影响;椎体后凸成形术后整体刚度和强度较骨折前仍无明显变化;椎体成形术后强化椎体自身最大载荷和刚度均明显升高,邻近椎体刚度降低但不显著(p>0.05),对邻近椎间盘高度影响明显(p

To investigate the mechanical effects of percutaneous vertebroplasty and percutancous kyphoplasty on adjacent discs and vertebral bodies. After 8 spinal functional units (T12~L2 segment: including 3 vertebral bodies and 2 intervertebral discs) were treated with intermediate vertebral fractures, calcium phosphate cement percutaneous vertebroplasty and percutancou kyphoplasty were performed in the middle vertebral body. The biomechanical indexes of the intermediate vertebral body and adjacent vertebral bodies before and after the fracture were measured. Studies had shown that the overall stiffne...
