Unilateral Lumbar Interbody Fusion

System Adonis®-UniLIF


The UniLIF technique is based on creating unilateral access to the intervertebral disc space by entering via an intervertebral foramen. Thus the UniLIF method allows a single posterior access enabling a “360°” fusion, which, amongst other benefits, offers the following advantages compared to the PLIF method:

• Unilateral facet resection
• Preservation of the lamina arch
• Preservation of the contralateral facet
• Minimal dural retraction
• Reduced risk of intradural scarring
• Revision strategy - only unilateral scarring

ADONIS®-UniLIF is an intelligent and, by virtue of the associated set of instruments, highly rational interbody device system that is a widely recognised and accepted product line offering the following benefits:

• Geometry is identical to the patient’s own sectional and sagittal anatomy
• Generous contact surface - reduced risk of migration

• Antegrade toothing for stable anchorage
• Contact surface for secure and permanent precision seating
• Significantly increased extraction forces

• Large filling aperture for rapid fusion
• Internal, conically shaped geometry of the cage holds the filling material
in the cage and increases the filling volume

Thanks to the choice of 2 materials:

• Titanium
The metal titanium has proven to be especially biocompatible and correspondingly easy to modify. It is proven that the various reactions of human cells are initiated by the surface oxides of the titanium substances, which are just a few nanometres thin.

Our PEEK material has been tested as per ISO 10993, classified according to US P-VI, and FDA Device and Drug Master Files are available.
