Figure 4

Micro-CT images of no treatment, PCL/PLGA hybrid scaffolds, PCL/PLGA/TCP hybrid scaffolds, and PCL/PLGA/duck beak hybrid scaffolds at 0, 4, 8, and 12 weeks after implantation. There was callus formation but no union in the control group at 12 weeks after the surgery. PCL/PLGA hybrid scaffold was similar to the control group at 0 weeks after implantation due to its low radiopacity. There were increased new bone densities, in PCL/PLGA/TCP hybrid scaffolds and PCL/PLGA/duck beak hybrid scaffolds at 8 and 12 weeks after implantation.
