Figure 6. Compression testing of the scaffolds and radius defect.

The results of compression testing showed that tubular scaffolds (Group C) demonstrated improved mechanical properties with higher compression strength in vivo than porous ones (Group A and B), indicating better bone formation and integration with the tubular scaffolds; the native solid scaffolds (Group D) showed the highest compression strength, but the lowest in vivo data after implantation (*p<0.05 vs. Group D, ⁺ p<0.05 vs. Group A and B).
