PMMA is the most used lesion filling at present; There is not significant difference between unipedicular and bipedicular vertebroplasty; Using vertebral body venography and appropriate dense bone cement can reduce leakage; Bolster for self-replacement can rebound vertebral body height, and Balloon-PKP and Sky-PKP can be avoided; In order to reduce refracture of vertebral body, anti-osteoporosis drugs should be used.

PMMA是目前最常用的填充物；单侧注射和双侧注射疗效没有明显差别；应用造影剂及掌握合适的骨水泥黏稠度可以减少骨水泥的渗漏率；术前腰部垫枕自身复位可以恢复椎体的高度，避免采用操作复杂且价格昂贵的球囊－PKP及Sky-PKP；进行PVP时应该配合应用抗骨质疏松药物，以减少椎体再骨折的发生。

Polymethyl methacrylate is the most used filling materials at present; There is not significant difference between unipedicular and bipedicular vertebroplasty; Using vertebral body venography and appropriate dense bone cement can reduce leakage of bone cement; Bolster for self-replacement can rebound vertebral body height, and balloon kyphoplasty and sky bone expander kyphoplasty can be avoided; In order to reduce refracture of vertebral body, anti-osteoporosis drugs should be used in the treatment of percutaneous vertebroplasty.

聚甲基丙烯酸甲酯是目前最常用的填充物；单侧注射和双侧注射疗效没有明显差别；应用对比剂及掌握合适的骨水泥黏稠度可以减少骨水泥的渗漏率；成形前腰部垫枕自身复位可以恢复椎体的高度，避免采用操作复杂及价格昂贵的球囊后凸成形及骨膨胀椎体后凸成形；进行经皮椎体成形时应该配合应用抗骨质疏松药物，以减少椎体再骨折的发生。

This paper discussed the influences of different cement, Inorganic Filler and the defoaming agent on the tensile strength and elongation at break of coating film;The influence of various of polymer-cement ratio (mass ratio of pure polymer to cement) and coating times on the tensile strength and elongation at break of coating film were researched;This paper also discussed the water Resistant Performance, watertightnessand the adhesion strength of wet subbase of coating film.
