Vertebroplasty with CT and Fluoroscopy Dual guidance: This movie shows the dual guidance system of CT and fluoroscopy

vert-Puncture Case 1

This movie illustrates vertebral puncture (transpedicular route) under dual guidance CT and fluoroscopy.

vert-Vertebroplasty 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.

vert-Puncture case 3

After vertebral puncture the stylet of the needle is removed. If bleeding is observed a phlebogram should be performed.

vert-Preparation of the cement

This movie illustrates cement preparation. A package of methyl methacrylate (Simplex ® Howmedica, Osteopal V ® Biomet Merck, Palacos ® Biomet) low viscosity is composed of 20 g powder and 20 ml fluid monomer. The acrylic glue is obtained by mixing the two components. Then half of the glue is thrown away. 3g of tantalum are added to the mixture in order to increase the radiopacity of the cement.

vert-cement injection case 1

Injection of the cement case 1: The movie shows cement injection under fluoroscopy control. In this case indication was osteoporosis ; optimal vertebral filling is required. A CT control is made at the end of the procedure.

vert-cement injection case 2

Injection of the cement case 2: The movie shows cement injection under fluoroscopy control. In this case indication was metastasis a low volume is sufficient. A CT control is made at the end of the procedure.

vert-pun-agif1

The principle of the vertebroplasty needle bevel. Use of the needle bevel to control the direction of the needle: The hub notch in medial position, bevel tip in medial position leading the course of the needle to the side ; The hub notch in side position, bevel tip in lateral position leading the course of the needle medially
