Currently available preparations of polymethylmethacrylate (PMMA) cement for percutaneous vertebroplasty have injectability times of 4-15 minutes. The potential for early polymerization requires procedures to be performed as fast as possible, sometimes with suboptimal results and waste of the cement. By cooling the PMMA mixture in an iced bath of sodium chloride solution, we can extend its injectability to over 2 hours and use one kit for the controlled treatment of multiple levels with successive needle placements. We have been using this technique since mid-1998, treating more than 600 vertebral bodies.
目前可用于经皮椎体成形术的聚甲基丙烯酸甲酯（PMMA）骨水泥制剂的可注射时间为4至15分钟。早期聚合的可能性要求手术尽快进行，有时结果并不理想且会造成骨水泥浪费。通过在氯化钠溶液冰浴中冷却PMMA混合物，我们可以将其可注射时间延长至2小时以上，并使用一套工具包通过连续进针对多个椎体进行可控治疗。自1998年年中以来，我们一直在使用这种技术，已治疗了600多个椎体。
