Vertebral Body Osteotomy

VBO®

A new way to achieve indirect decompression, while preserving motion.

Vertebral Body Osteotomy (VBO) restores foraminal height within a single vertebra, relieving nerve compression without fusing across the disc, with implant options designed to address sagittal and coronal alignment. It’s performed through one lateral approach using the FDA-cleared Vertiwedge® system.

The clinical problem

Indirect decompression without interbody fusion.

Surgeons treating foraminal stenosis have typically had to choose. Direct decompression preserves motion but doesn’t restore height or address alignment. Interbody fusion achieves indirect decompression and correction, but joins two vertebrae across the disc. For patients, that often means choosing between living with the pain and giving up motion. For appropriately selected patients, VBO is designed to offer indirect decompression and alignment options while preserving motion at the disc.

How VBO compares

Decompression, alignment, and motion, in one procedure.

Each approach has its place. The difference is how decompression is achieved, where height is restored, and what happens to motion across the disc.

Feature Direct decompression Interbody fusion VBO
Decompression Direct Indirect Indirect
Implant location None Disc space Within one vertebral body
Restores foraminal height No Yes Yes
Alignment options Not addressed Lordotic and coronal implants Lordotic and coronal implants
Motion across the disc Preserved Fused Designed to be preserved

Direct decompression includes procedures such as foraminotomy and laminectomy. Interlaminar devices are not included here because their mechanisms and use vary.

Direct decompression and interbody fusion remain appropriate options for many patients and spinal conditions. VBO is intended for appropriately selected patients.

How VBO works

Four steps, one lateral approach.

VBO creates correction within one vertebral body. Bone healing occurs across the osteotomy inside that vertebra rather than between neighboring vertebrae, so the procedure is designed to preserve motion at the disc.

Bone screws and a lateral plate secure the near side; Vertiwedge’s deployable staple secures the far side, all through the same approach.

The technology behind VBO

Bilateral fixation through a single incision.

VBO is the procedure. Vertiwedge® is the FDA-cleared intraosseous system that restores and supports height. Bone screws and a lateral plate secure the near side of the vertebra, and a proprietary deployable staple mechanism, protected by issued and pending patents, secures the far side. Vertiwedge is available in a wide range of sizes and lordotic and coronal angulations.

Indications

Who may be a candidate for VBO.

Vertiwedge® is cleared for use in the thoracolumbar spine from T1–L5 to partially replace a diseased or damaged vertebral body and/or restore the height of a collapsed vertebral body following an osteotomy. The cleared indications include degenerative spine disease and previous trauma, including fracture or tumor. The system is used with bone graft and its contralateral staple.

The cleared labeling also includes use in certain advanced-stage tumor cases when life expectancy is insufficient to permit fusion. This summary does not replace the full labeling or a surgeon’s clinical judgment.
