Treatments · Spinal Stabilization
The gold standard for spinal stabilization when motion preservation isn't appropriate — providing permanent stability for instability, deformity, and complex spine conditions.
Stability-first philosophy
Spinal fusion permanently joins two or more vertebrae to eliminate painful motion and provide stability. While it sacrifices motion at the fused levels, fusion remains the most reliable treatment for conditions involving instability, deformity, or when motion preservation is unsafe.
Modern fusion techniques focus on achieving solid arthrodesis while minimizing adjacent level stress through proper alignment restoration and selective level inclusion.
Eliminates abnormal motion and provides lasting stability
Restores proper spinal alignment and balance
Decades of successful outcomes for complex conditions
Surgical approaches
Multiple approaches to achieve solid fusion and optimal alignment. The direction of access is chosen by what the segment needs, not by habit.
Most common approach for lumbar fusion
Posterior approach through the back muscles, allowing direct visualization of neural elements and placement of pedicle screws for rigid fixation.
Front approach for interbody fusion
Anterior approach allows direct access to the disc space for interbody fusion, providing excellent lordosis restoration and load sharing.
Circumferential fusion for complex cases
Combined anterior and posterior approaches provide maximum stability and fusion surface area for complex deformity or revision cases.
Side approach minimizing muscle disruption
Lateral transpsoas approach allows interbody fusion with minimal muscle disruption and excellent indirect decompression.

Frequently asked questions
Because motion preservation is not always safe. Where a level is unstable, deformed, or has lost the facet joints that keep it under control, keeping it moving would make things worse rather than better. Fusion is recommended here when it is the right answer for that level — and where a level can safely keep moving, an artificial disc is offered instead. Many patients receive both in one operation; that is what a hybrid construct is.
Motion is lost at the fused levels only, not across the whole spine. A single-level fusion in the lower back is often barely noticeable in daily life, because neighbouring levels take up the range. The more levels included, the more noticeable it becomes — which is why selective level inclusion, fusing only what needs fusing, matters so much.
Nonunion means the bone fails to knit into one solid mass, so the segment stays mobile despite the hardware. It is the main thing that can undermine an otherwise well-performed fusion, and it is strongly influenced by factors you control — smoking above all, then bone health and following activity restrictions during healing. It is listed under complications above because it is real, not because it is common.
Modern titanium instrumentation rarely triggers airport scanners, and where it does, the screening is routine. The hardware is designed to stay in permanently; it is not removed once the fusion is solid unless it causes a specific problem.
A fused level no longer moves, so the levels immediately above and below take on more load and may degenerate over time. It cannot be eliminated, but it can be reduced — by restoring proper alignment, by including only the levels that genuinely need fusing, and where appropriate by preserving motion at a neighbouring level rather than extending the fusion.
Consolidation is assessed over months rather than weeks, with imaging at follow-up appointments through the first year. Most patients are cleared for full activity within 3 to 6 months, once the fusion is judged solid. Feeling well at three months is encouraging but is not the same as a consolidated fusion — which is why the activity restrictions matter.
