Lumbar Non-Fusion


TOPS: An Alternative to Lumbar Fusions

The TOPS System is a mechanical device that restores motion in all directions – flexion, extension, lateral bending, and axial rotation. Instead of permanently locking the two vertebrae with a fusion, your surgeon allows the two vertebrae to continue moving with the assistance of the TOPS™ device. 

The implant facilitates bending, straightening and twisting movements at the affected level of the spine while blocking excessive sagittal translation motions. 

The internal stoppers of the TOPS System replace the removed bony elements that served as stoppers during axial rotation, flexion, extension, and side bending. 

If you suffer from one or more of the following conditions: 
• Radiating leg pain 
• Greater leg / buttock pain than back pain 
• Severe pain sets in when walking as little as 
• 100 yards or 2 minutes 
• Pain reduces when sitting, bending forward, or leaning over a shopping cart 

These symptoms could be signs of degenerative spondylolisthesis, spinal stenosis, and additional spinal conditions.
