Method:Imitate environment of human body, and five vertebral body, temperature was measured with five 5ml bone cement ball and five vertebral body with 5ml done cement injection, both were placed in a bath (37℃). Result: the peak temperatures in cement ball center were 63.1~65.4℃, the time above 50 degrees C were for 66~73 second, and away from ball face 5mm peak temperatures were 42~56.3℃. the time above 50℃ was for 28~30 second. The center temperature in vertebral body was 42~46℃ Conclusion: The peak temperature was lower and the time above 50℃ was shorter in imitated environment. There was no thermal damage during polymerization in vertebroplasty. [Key wo...
