The morphological changes of cortical bones fixed by LCP and LC-DCP for different periods were examined by MicroCT. a–f Representative images show the morphology of the cortical bone around one screw at different periods (6 weeks, a and d; 12 weeks, b and e; 24 weeks, c and f) for different plates (LC-DCP, a–c; LCP, d–f). The parameters were as follows: height of 5 mm, threshold of 1800; ROI completely included the lateral cortical bone; and the cortical bone was displayed as the pseudo color brown for distinction. g The TMD values at different time points (6 weeks, 12 weeks, and 24 weeks) for the LCP and LC-DCP plates were summarized. n = 4 for each group; *P < 0.05, **P < 0.01, compared with the LCP group
