steps to bone repair

hematoma, cartilaginous callus, bony callus, remodeling (osteoclast)

22
New cards

hematoma

a solid swelling of clotted blood within the tissues.

New cards

calluses form

periosteum cell mutiply and move to fracture -> callus

inside calluses -> chrondrocytes make cartilage
