The correct order (from start to finish) of fracture repair is ________.
2, 1, 5, 4, 3
Label in order steps 1 through 5 of endochondral ossification.
-calcification of cartilage in the center of the diaphysis
-formation of bone collar around the diaphysis of the hyaline model
-ossification of the epiphysis
-formation of the medullary cavity as ossification continues
-invasion of internal cavities by the periosteal bud and spongy bone formation
hematoma formation
caused by tearing of blood vessels in and around fracture site
fibrocartilage callus
activity of fibroblasts and osteoblasts creates an overgrown splint around the fracture site
bony callus formation
trabeculae invade callus and begin to replace fibrous tissue
bone remodeling
excess bony material is removed from the external and internal surfaces of the diaphysis
