Vertebral Body Stent (VBS or Stentoplasty) and Vertecem V+

Roger Härtl, Jean Ouellet, Andreas Korge, Robert McGuire, Paul Heini

The vertebral body stent (VBS) system is a minimally invasive, percutaneous, reconstructive treatment for vertebral body fractures. The VBS system is intended for the reduction of painful vertebral compression fractures and/or creation of a void in cancellous bone in the spine for the treatment of levels ranging from T5-L5. It is intended to be used in combination with a legally marketed polymethylmethacrylate (PMMA)-based bone cement adequately indicated for use in vertebroplasty or kyphoplasty procedures.

Vertecem V+

Vertecem V+ is for percutaneous injection of PMMA as filler material within (eg, stentoplasty) or without (vertebroplasty) an intervertebral framework. Many different products are available on the market to cover both solutions.

Vertecem V+ is unique because it:

  • Is ready to use directly upon mixing (no need to wait for the cement to reach the right viscosity)
  • Offers prolonged working time (less stress for the surgeon through reduced time constraints/the opportunity to perform multilevel interventions)
  • Offers better visibility under x-ray through the incorporation of more radiopacifiers, which are also distributed more evenly inside the PMMA cement

The vertecem V+ syringe kit offers syringes in 5 x 2 mL and 8 x 2 mL sizes. The design features strong syringes, color coding for different volumes, and ergonomic handling.

The vertebroplasty needle kit features 8 gauge (blue), 10 gauge (yellow), and 12 gauge (green) diamond- and beveled-tip needles. It also offers an optional biopsy solution for 8 gauge and 10 gauge needles.

The design of this product achieves three goals:

  • Long working time: (up to 27 minutes at room temperature) therefore less stress for the surgeon during the intervention and enough time for multilevel procedures.
  • Increased initial viscosity: Ready to use directly upon mixing. Potentially lower risk for leakage and shorter operative time.
  • Better x-ray visibility: Better control of cement flow and thus less risk of leakage.
