Efficacy of Navigation Systems With Smart Delivery Tools in Enhancing the Accuracy of Percutaneous Pedicle Screw Insertion.

Purpose Minimally invasive surgical techniques are advancing in spinal surgery, creating a need for the development of surgical support systems. This study evaluates the efficacy of a compact navigation system with smart delivery tools in percutaneous pedicle screw insertion. Methods This retrospective observational study included consecutive thoracic or lumbar spinal fusion patients with percutaneous pedicle screw placement treated from November 2022 to July 2023 in a Japanese private hospital.

Step-by-Step Sublaminar Approach With a Newly-Designed Spinal Endoscope for Unilateral-Approach Bilateral Decompression in Spinal Stenosis.

Objective: Spinal stenosis is increasingly common due to population aging. In elderly patients with lumbar central canal stenosis (LCCS), minimizing muscle damage and bone resection is particularly important. We performed a step-by-step operation with a newly designed spinal endoscope to obtain adequate decompression in patients with spinal stenosis.
