If the neurological release is critical in spinal surgery, the maintenance or restoration of stability and mechanical balance of the spine is equally.
This stability and sagittal balance can be ensured by a rigid fusion, which restores the physiological curvature, the height of the intervertebral space and the foramina.
Spinal fusion solves many problems but can induce an overload of adjacent levels. Thisleads to the concept of dynamic stabilization or “Non-Fusion” in spine surgery.
Let’s see : The “Non-Fusion”
