A kind of multifunctional and environmental friendly powder putty has been prepared based on coal ash powder and ground calcium Carbonate and so on as fillers and dry emulsion powder and cement as binder, mixed with proper powder additives and other auxiliaries.

以乳胶粉、水泥为粘结料，粉煤灰、重质碳酸钙、石英砂等为填充料，配以适当的粉末状助剂，制得了一种粉末腻子；探讨了乳胶粉、纤维素醚、水泥、粉煤灰以及复合填料的用量对粉末腻子性能的影响，优化出较佳的粉末腻子配方；测试了粉末腻子的理化性能。

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。
