Pedicle screw fixation is a widely used spinal stabilization technique that involves the insertion of screws into the pedicles of the vertebrae to anchor rods and secure spinal segments. This method provides rigid internal support, often used in spinal fusion surgeries to correct deformities, treat fractures, or stabilize degenerative conditions. By maintaining proper spinal alignment during healing, it enhances the success rate of fusion and reduces the risk of further injury. Advanced surgical navigation systems, like those developed by HRS Navigation, offer real-time guidance during pedicle screw placement, ensuring optimal accuracy and improving overall patient outcomes in spine surgery.
