Summary

This study aims to compare three-dimensional (3D) and two-dimensional (2D) visualization in biportal endoscopic spine surgery using a simulated environment. Surgeons will perform standardized tasks on a spine model while using either 3D or 2D endoscopic systems. The goal is to determine whether 3D technology can improve precision, efficiency, and movement control during surgery. The study uses a randomized, blinded, crossover design to ensure objective results and may help guide future training and technology use in spinal endoscopy.

Interventions

DEVICE

Three-Dimensional Endoscopic Visualization

Use of a stereoscopic 3D high-definition endoscopic system with dual optical channels, projecting to a stereoscopic monitor viewed with polarized glasses, to perform standardized spinal simulation tasks.

DEVICE

Two-Dimensional Endoscopic Visualization

Use of the same high-definition endoscopic system with stereoscopic function deactivated, providing conventional monoscopic two-dimensional visualization, to perform standardized spinal simulation tasks.
