In some cases, the height of vertebra could be increased after the operation, however, it is not for the technology but for the posture of patients that the patients would pronate on the table and over-straight their bodies. In this situation, bone cement can be injected into the vertebras and enhance the int ensity, change the spine kyphosis, recover the spine physiological line, so it gets to the aim of treatment.

有时病椎术后高度增加，不是椎体成形术操作本身抬高椎体高度，而是在病人俯卧位时进行的体位引起过伸而复位，此时椎体内再加入骨水泥固化，使椎体固定在复位后的位置上，并且增加了耐压强度，同时改变了脊柱的后凸畸形，恢复了脊柱生理力线，这样就会达到治疗目的。
