puncture case 2

The movie describes the use of the vertebroplasty needle bevel. The aim of this bevel is to allow precise course correction of the needle inside bone tissue by changing the bevel direction (fig 34). Hammering will lead the needle on the course determined by the bevel direction. According to the bevel tip direction (right, left, up or down) the course of the needle will be modified. This technique allows an optimal placement of the vertebroplasty needle.
