Fig. (3A) Photograph of “L-shape-plate” explants after 3 months in-situ, where the injection-molded screws of 2.0mm diameter show more opacity. Size of the implant and material composition affect both degradation behavior, the latter can be ruled-out as the polymer is identical. Moreover at the inferior left corner, a 2.5 mm-system screw shows lower opacity probably due to her bigger diameter and volume that per-mits only slower hydrolysis as in the 2.0 mm screws. Upon removal the L-plates were cut at their knee, as such three-hole fragments could easily be positioned in the fatigue test set-up.
