A comparison between Diffuse Reflection Spectroscopy and Electrical Impedance Spectroscopy to distinguish between different vertebrae tissue during spinal fusion surgery

Accurate placement of screws in spinal surgery is vital to mitigate risks like instability, nerve damage, or spinal cord injury, which can lead to various complications such as pain, sensory loss, muscle weakness, or paralysis below the injury site [33]. However, success rates in screw placement vary widely, ranging from 27.6% to 100% [56].<br/>...

Design of a combined optical and structural bone phantom: Concept validation and design tool

Introduction: Although being the most advanced spinal stabilization method, pedicle screw fixation has an increased number of complications compared to other surgical procedures, due to the complex spinal anatomy, large inter-patient anatomical variability, and the highly vulnerable surrounding tissue of the spine. Screw fixation strength can be...
