Figure 4.

Reconstructed µCT images showing the residual metallic magnesium. The 3D structure of the remaining magnesium metal has been extracted from the µCT data and presented for each timepoint. Due to the small size and few samples with remaining magnesium metal (3 samples with remnants out of 16 samples) at the 52-week timepoint, the residual 3D metallic structure of the screw could not be recreated. Mineralized magnesium degradation products can be seen retaining a partial shape of the degraded fixation screw.
