Quantitative assessment of cranial fixation stability using a sensor-equipped head fixation device in neurosurgical simulations.

ABSTRACT:

Purpose

Reliable head fixation is essential for accuracy in cranial neurosurgical procedures, particularly when using neuronavigation systems. While traditional skull clamps are designed to ensure rigid immobilization, undiscovered movement of patient´s head under external forces can undermine surgical precision.

Methods

In this study, we investigate the biomechanical performance of a head fixation device equipped with force and angle sensors. Using seven cadaveric heads and an external force applicator, we quantified resistance against the external force, the axial force at each pin and angular displacement of the two-pin rocker. The movement of head across three clinically relevant head positions for craniotomy: prone, middle fossa, and pterional was optically recorded by
