Figure 7.

Newly repaired trabeculae are not fully collagen loaded (blue stain represent collagen). (Left) larger amount of new trabeculae were less collagen loaded in the fracture healing zone by day 7 (Arrow); (Middle) only very tiny part of the normal trabeculae were not fully collagen loaded which was a sign of normal bone remodeling process (Arrow); (Right) immature trabecular area percentage of fracture region were significantly higher than normal bone tissue (P<0.05).
