Surface characterization of retrieved ZX00 implants after 6-, 12-, and 24- weeks of in vivo implantation. a) before implantation, b) after 6-, c) 12- weeks, and d) 24- weeks of implantation,e) corresponding EDX analyses of the corrosion products formed on the different screw zones: head – red dotted line, shaft –green dotted line, valley – blue dotted line. Data presented as mean ± standard deviation (n = 47–50 EDX point measurements/time point from 3 independent samples). (The figure should be printed in color).
