Figure 5.
Micro-computed tomography (CT) degradation analysis of the iron suture groups. ST decreased (A) and SSV/OV percentage increased (B) sequentially from the preoperative period until 12 weeks postoperatively. Reconstructed micro-CT images observed preoperatively and at 12 weeks postoperatively (C). ST: structure thickness (mm), SSV: small implant fragments < 0.18 mm in diameter (small-structure volume), OV: object volume, and SSV/OV (%) denoted the small fragment percentage of the implant in the region of interest. The error bar represents the standard deviation.
