Preliminary evaluation of mixed reality navigation with single-vertebra registration in spinal surgery.

ABSTRACT:

Objective

To develop a mixed reality navigation system based on single-vertebra registration and to preliminarily validate its feasibility in clinical surgery, providing a potential reference for spinal surgical navigation registration methods.

Methods

We developed a portable, stand-alone, optical-based mixed reality navigation system for spinal surgery using a head-mounted display. The system integrates registration and real-time localization functions, enabling single-vertebra registration via anatomical landmarks and interactive visualization through the HoloLens 2 platform. System performance was evaluated in both laboratory and clinical settings by measuring localization time, fiducial registration error (FRE), and target registration error (TRE).
