Spine Ref

An innovative device to assist with spinal surgery using FluoroNavigation

Navigation assistance and support for minimally invasive operations

Operations on the spinal column are particularly sensitive, especially considering the risk of neurological complications. The performance of minimally invasive surgical techniques depends on navigation assistance systems to help guide the surgeon. To clearly display the area to be operated on and assist the surgeon in the procedure, a stable, precise, ergonomic support is crucial.

Developed as a solution to the many problems involved in spinal surgery, the Spine Ref device offers surgical navigation systems with a more reliable and solid working surface, and therefore more precise navigation in surgical terms.

Spine Ref: minimally invasive support to increase precision in navigation

Spine Ref is a positioning device for optical navigation systems that is placed on the patient’s back. Its percutaneous  attachment to several adjacent vertebrae makes this minimally invasive device safer and more stable. In this way, navigation becomes more precise and the operation is much more likely to be successful.


Spine Ref


  • Stability: through extension of invasive clamps on several adjacent spinal processes
  • Precise positioning of tools: by stabilising the frame’s attachment, Spine Ref avoids secondary shifting of the tools during the operation
  • Ergonomic: user-friendly
  • Low density radio-transparency: does not pose a problem for the capture of images necessary for surgical procedures
  • Simple manufacture and easy to use: one single part that is ergonomic and easily mass produced
  • Cost-effective: Low production costs, one single part, easily mass produced.

Spine Ref: a device that has been tested in a medical environment

20 beta-testers partnered with surgeons are in the process of clinically validating this technology.


This technology is protected by a registered patent (No. FR0900323)

Spine Ref meets surgical requirements

The Spine Ref tool was designed in collaboration with scientific teams from the Grenoble CHU (Teaching Hospital) with the goal of finding a solution to the restrictions involved in thoracolumbar surgery.

  • Adaptable to different types of frame
    Its use is completely compatible with current surgical instruments
  • Reduction in trauma experienced by the patient
    Thanks to percutaneous attachments to the spinous process of the spinal column, this tool is minimally invasive for the patient
  • Reduced risk during the operation
  • High efficiency against transmission of prions
    An efficient single piece of equipment that meets anti-prion health standards
  • Minimally-invasive
    Class 1 apparatus that is easily adapted to European standards

Market Perspectives

  • Computer assisted surgery, in particular on the spinal column
  • Computer assisted surgery including knee, hip, and shoulder surgery
  • Minimally invasive operations (fluoronavigation, etc.)

Development Perspectives

We are currently looking for partners who would like to put forward minimally invasive, reliable, precise solutions for surgical navigation assistance.
