VBO targets the source of compression.
For appropriately selected patients whose nerve compression comes from lost foraminal height.
A new option in spine surgery
Foundation Surgical develops spine procedures designed to relieve nerve compression without giving up motion. Our flagship procedure, Vertebral Body Osteotomy (VBO®), restores height within a single vertebra, so neighboring vertebrae aren’t fused across the disc.
The VBO difference
VBO®VBO (Vertebral Body Osteotomy) is a motion-preserving procedure that restores height within a single vertebra.
Instead of joining two vertebrae together, VBO is designed to create more room for the nerve by restoring height within a single vertebra. Correction and bone healing stay within one bone, and the discs above and below it are left to move.

How VBO works
For appropriately selected patients whose nerve compression comes from lost foraminal height.
A controlled osteotomy, supported by the Vertiwedge® implant, restores and holds vertebral body height.
Because neighboring vertebrae aren’t fused across a disc space, VBO is designed as a motion-preserving option.
Vertiwedge® Intraosseous System
Bone screws and a lateral plate provide ipsilateral fixation. A proprietary deployable staple mechanism, protected by issued and pending patents, extends across the vertebral body to provide contralateral fixation, all through the same lateral approach.
Contralateral fixation: the deployable staple.




Our technologies
Motion preservation is our focus. VBO® with Vertiwedge® restores height within a single vertebra without fusing across the disc. When fusion is clinically appropriate, LLIF180™ with the Interwedge® implant offers a standalone lateral interbody solution built around the same bilateral fixation platform.

Talk to our team
“When patients hear they need a fusion, too many feel their only options are to live with the pain or accept a fusion that limits how they move. VBO was built to give them another choice.”
Randal Betz, MD, Founder and CEO. Past President of the Scoliosis Research Society and former Chief of Staff at Shriners Hospitals for Children–Philadelphia, Dr. Betz pioneered intravertebral correction, the principle behind VBO, more than 25 years ago.
