| 摘 要： | 椎弓根螺钉内固定系统为治疗骨质疏松性胸腰椎退行性疾病的主要装置。然而，骨密度的严重丢失造成骨质疏松性椎体对椎弓根螺钉的固定强度下降，内固定失败的发生率显著增加。骨水泥强化椎弓根螺钉技术是一种改善骨质疏松性胸腰椎术后内固定生物力学稳定性的有效方法，大量研究证明其能显著增加椎弓根螺钉的固定强度，但存在骨水泥渗漏等风险。本文从骨水泥强化椎弓根螺钉技术展开分析，对骨水泥强化椎弓根螺钉的适应证、骨水泥强化椎弓根螺钉的生物力学变化、骨水泥增强材料、注入体积及分布进行介绍，并对新型骨水泥材料及螺钉设计做了展望。

| Abstract: | Pedicle screw fixation system is the main device for the treatment of osteoporotic thoracolumbar degenerative diseases. However, the loss of bone mineral density resulted in a decrease in biomechanical properties of osteoporotic vertebral pedicle screws and a significant increase in the incidence of internal fixation failure. Augmentation of pedicle screws with bone cement is recommended as an effective method to improve the biomechanical stability of osteoporotic thoracolumbar spine internal fixation, and it has been shown in a large number of studies to significantly increase the fixation strength of pedicle screws, but there is still a risk of cement leakage. This review focuses on the analysis of cement-reinforced pedicle screw technology, introduces the biomechanical changes of cement-reinforced pedicle screw in pedicle screw design, augmentation materials, volume and distribution of the injected cement, and looks into the future of new cement materials and innovative screw design. |
