Composition of the surface elemental analysis by X-ray photoelectron spectroscopy. By measuring the energy distribution of photoelectrons generated after irradiation with X-rays on the sample surface, we were able to analyze the constituent elements and electronic states of our instrumentation samples. The actual titanium instrumentation used in lumbar fusion surgery 1 year after production is shown. We used PROSPACE® intervertebral cages (B-Braun Company, Melsungen, Germany) in all patients in this study. The surface of the PROSPACE® is pure titanium, which covers a Ti-6Al-4 V alloy. Actual titanium instrumentation that underwent ultraviolet photofunctionalization had a decreased amount of carbon attached to it. Vertical axis: photoelectron speed (C/S: counts / sec). Horizontal axis: binding energy (eV: electronvolt)
