Universal manual drilling system for foraminotomy

The instrument set is used to create surgical access ports in endoscopic or endoscopically supported interventions/operations on the lumbar spine, in particular if bone structures have to be removed on the way to the surgical site on account of anatomical special features or pathological changes. 

Typical indications for the use of manual burrs are foraminal stenoses due to degenerative changes at the pedicle or facets.

The removal of bony barriers can be effectively carried out after positioning of special working sleeves using manual burrs under X-ray vision. The special shapes of the working sleeves protect the surrounding neural structures against mechanical damage in this process.

The instruments provide a supplement to the existing VERTEBRIS lumbar systems.


The RIWOspine education program offers excellent possibilities to learn more about the full-endoscopic technique for spine surgery or interventional percutaneous spine pain therapy.

It is a comprehensive training concept consisting of different modules to implement these innovative techniques successfully in your hospital.
