Distraction Arthrodesis

DIANA Implantat

DIANA:

The SI-Fusion system utilizes the distraction-interposition method to provide a simple and safe fusion technique for the sacroiliac joint.  Reproducible placement of the Titanium Interference-Screw is achieved using sequential instrumentation with ligamentotaxis stabilizing the joint during the fusion process.

The unique, but intuitive design of the clinically-proven technique and instrumentation keeps the procedure ‘in the safe zone’ and greatly reduces the risk of the complications that have been associated with traditional fusion techniques.  The color-coded instrumentation and implants together with the simple, step-wise technique reduces the learning curve and may reduce the risk of complications. Through the unique surgical approach, preparation of the extra-articular recess and generous grafting it is possible to optimize the environment for a successful fusion.

The application-specific design of the implant provides structural support for stability while facilitating fusion.  A range of implant sizes is available to accommodate anatomical differences.

Application

The system is indicated for painful sacroiliac joint requiring surgical stabilization by bone grafting and internal fixation as caused by

  • Sacroiliac Joint degeneration
  • Injury or fall
  • Previous back surgery that causes additional stress on the SI-Joint

Specific Advantages:

  • Implant Geometry
  • Conical design to optimize stability
  • Self cutting thread
  • Hollow and fenestrated to support fusion
