摘要
随着我国人口老龄化的日益加剧,如何有效的提高骨质疏松条件下椎弓根螺钉的稳定性、防止螺钉松动已经成为脊柱外科亟待解决的难题。目前凭借出色的机械强度,PMMA已经被广泛的应用于强化骨质疏松条件下椎弓根螺钉的稳定性。然而在众多的研究中,PMMA的注射剂量、注射方法及椎弓根螺钉的设计差异很大。本文就目前PMMA强化骨质疏松条件下椎弓根螺钉稳定性的研究进展做一综述。
With the aging of the population aggravating in our country, how to effectively increase the stability of pedicle screw in patients with osteoporosis （OP） and to prevent loosening of the screw has become an urgent problem in spine surgery. Based on the effective mechanical strength, Polymethylmethacrylate （PMMA） has been widely used in the augmentation of pedicle screw stability in patients with OP. However, the injection methods of PMMA, injected volume of PMMA, and the design of pedicle screw in various researches are different. This paper reviews research progress of augmentation of pediele screw stability with PMMA in patients with OP.
