More sufficient blood supply was found in the fracture healing zone and distribution of local blood supply were altered. (Left) large blood sinus was shown in the fracture region (Shown by letter B); (Middle) much smaller blood vessels were found in the normal bone tissue and majority of the blood supply lied along the proximal edge of the epiphysis plate (Shown by small arrows); (Right) Blood supply transection areaof fracture healing zone was significantly larger than normal bone tissue (P<0.05).
