Stability with movement
Flexible constructs share load with the spine rather than eliminating motion — support without rigidity.

Posterior Dynamic Stabilization
A motion-preserving alternative approached from the back of the spine, stabilising without rigid fusion.
What it is
Support that still moves
Posterior dynamic stabilization steadies an unstable segment with flexible posterior constructs — controlling harmful motion while preserving healthy movement. It belongs to motion preservation, approached from behind rather than through the abdomen.
Posterior approach
Placed from the back, it suits levels and pathologies where an anterior disc replacement is not the answer.
Facet-friendly
By unloading rather than locking the segment, it protects the small posterior joints instead of bypassing them.
Between injections and fusion
For spines needing more than pain therapy but less than rigid stabilisation, it fills the middle ground.
What to expect
Planned, imaged, verified
Every element is positioned to your anatomy under live imaging, with movement confirmed before closure.
01
Planned placement
Screw-based anchors connected by flexible elements, positioned under imaging to match your anatomy.
02
Motion verified
The construct is tested through range before closure — supported, but moving.
03
Aftercare
Structured rehabilitation rebuilds the muscles that share the load long-term. Report fever, worsening pain or new neurology promptly.
Common questions
Things patients ask us
How is this different from fusion?
Fusion eliminates motion at the level; dynamic stabilization controls excessive motion while preserving it. Stability with movement, not instead of it.
How is it different from disc replacement?
Disc replacement works from the front and replaces the disc; dynamic stabilization works from behind and supports the segment. Different doors for different problems.
What are the risks?
Hardware loosening or breakage, infection and bleeding are the general considerations; persistent pain despite correct placement is possible, which is why selection matters most.
Who is it for?
Patients with instability or load-related pain whose facets, alignment and bone suit support rather than locking — your scan and examination decide.
