Figure 3. (a) Fibrous union findings at the control group fracture site in the second week (H&E, x100). Connective tissue areas and lymphocytic cell infiltration are seen between bone trabeculae. (b) Findings of osteochondral union at the quercetin group fracture site in the second week (H&E, x100). Enchondral ossification areas consisting of cartilage structures and woven type immature bone tissue are seen. (c) At the fourth week, bony union findings at the fracture site of the control group (H&E, x100). Among the bone trabeculae, ossification areas formed in woven type immature bone tissue are seen. (d) At the fourth week, signs of osteochondral union at the quercetin group fracture site (H&E, x100). Between the bone trabeculae, enchondral ossification areas consisting of woven type immature bone tissue and cartilage areas are seen.
