骨水泥强化椎弓根螺钉技术的研究进展

Research progress of cement-augmented pedicle screw instrumentation technique

骨质疏松症是造成脊柱术后内固定松动的重要原因,骨水泥强化椎弓根螺钉(CAPSI)技术是目前临床上应用最广泛的提高椎弓根螺钉稳定性的技术,主要用于骨质疏松症和翻修手术,包括骨水泥预填充传统螺钉技术和骨水泥强化空心侧孔椎弓根螺钉技术。CAPSI技术可能引起骨水泥渗漏和肺栓塞,其适应证及技术要点尚未达成共识。因此,本文就CAPSI技术的研究进展作一综述,以期为临床提供相关参考。

Osteoporosis is an important cause of internal fixation loosening after spinal surgery.Cement-augmented pedicle screw instru-mentation(CAPSI)technique is the most widely used technique in clinical practice to improve the stability of pedicle screw,mainly applied in osteoporosis and revision surgery,which included conventional solid pedicles crews and fenestrated/cannulated pedicle screws technique.CAPSI technique may cause cement leakage and pulmonary embolism,and there is no consensus on its indications or technical points.Therefore,this article reviews the research progress of CAPSI,in order to provide relevant reference for clinical practice.
