The document outlines the basic and optional instruments used for spinal operations, specifically detailing various types of retractors, elevators, and tools for specific spinal levels. It emphasizes the preparation and selection of instruments based on the surgical approach, spinal instrumentation, and the surgeon's preference. Additionally, it discusses the tools required for screw, hook, and wire insertion, particularly for cervical instrumentation systems.
