Principle

The analgesic effect of cement cannot be explained by the consolidation of the pathological bone alone. In fact, good pain relief is obtained after injection of only 2 ml of methyl methacrylate in metastasis. In these cases the consolidation effect is minimal. The methyl methacrylate is cytotoxic due to its chemical and thermal effect during polymerization. The temperature during polymerization is high enough to produce coagulation of the tumoral cells. Therefore, good pain relief can be obtained with a low volume of glue.
