Abstract
BACKGROUND: Sufficient visualisation of the operating field is crucial for success in surgery and is important especially concerning minimal invasive and deep approaches in spine surgery METHODS: The spinal microsurgical approach was imitated using an isolated box that was accessed with different devices. Different light sources and auxiliary devices were analysed aiming to compare them to each other. As light source we used one microscope, one standard operating theatre lamp and one headlamp. The auxiliary devices included different tubes with and without optic light fibre, different retractors and one endoscope RESULTS/CONCLUSION: Hence, we demonstrated that different combinations of light sources and auxiliary devices provide significantly different illumination in the artificial operating field. A tube with optic fibres seems to be superior for non-microspical approaches. The smaller these tubes in diameter, there is the higher the illuminance on the surgical focus. The combination of tube and microscope seems to be the best choice for deep approaches in microsurgical spinal surgery. An endoscope supplies illuminance comparable to a surgical microscope.
