instrumentation
Metallic hardware system used to stabilize the spine during fusion procedures.
Full Definition
In spine surgery, instrumentation refers to the comprehensive system of metallic implants including screws, rods, plates, hooks, and connectors used to provide immediate mechanical stability to spinal segments. Modern instrumentation systems are typically made of titanium or stainless steel and serve as internal scaffolding while biological fusion occurs. The instrumentation maintains alignment, prevents motion, and provides structural support during the healing process.
Usage
Usage note: Broader term encompassing all metallic components used in spinal fixation.
