Spinal Instrumentation
Surgical hardware used to stabilize, correct, or fuse segments of the spine.
Full Definition
Spinal instrumentation refers to the various metal implants and devices used in spine surgery to achieve stabilization, deformity correction, or fusion of spinal segments. Common components include pedicle screws, rods, hooks, wires, and interbody cages made from materials such as titanium or stainless steel. Instrumentation systems can be anterior, posterior, or combined approaches, and may be used for conditions including degenerative disease, trauma, deformity, or instability. Modern instrumentation allows for three-dimensional correction and maintains alignment during the fusion process.
Usage
Usage note: Refers specifically to metal hardware, not the surgical procedure itself.
