Whole and Segmental Vertebra Derotation Screw Systems are specialized spinal instrumentation used to correct 3D deformity, particularly scoliosis, by simultaneously translating and rotating vertebrae. These systems (like or ) use pedicle screws, specialized connectors, and derotation handles to apply direct vertebral body derotation (DVBD) to the apical or multiple segments. This technique reduces rib humps and restores sagittal alignment, improving on traditional rod-only rotation techniques.

Derotation Instruments/Handles: Attached directly to the heads of pedicle screws (or to rods) to apply torque and correct apical vertebrae.
Connectors/Clips: Used to link adjacent screws together to allow for segmental (multi-level) derotation, increasing the force applied to the spine.
Pedicle Screws: Polyaxial or uniplanar screws act as anchors, often placed in high-density constructs on the concave side.
Reduced Set Screws: Specialized screws and drivers are used to lower the rod into the screw head, often used in conjunction with "tower" reducers to pull the spine to the rod.

Apical Derotation: The system is applied at the apex of the deformity (most rotated vertebrae) to improve the 3D correction.
Segmental Derotation: Connects multiple screw segments simultaneously, which is highly efficient for correcting complex, rigid, or large-curve scoliosis.
Screw Design Impact: Fixed-axis or uniplanar screw heads are favored because they allow for better transmission of torque compared to traditional polyaxial screws, which may allow for excessive toggling during the maneuver.
Workflow: The process generally involves placing screws, reducing the rod, attaching derotation instruments, performing the maneuver, and holding the correction while tightening the screws.
