Fracture healing is a complex physiological process that involves the coordinated participation of several cell types. Unlike other tissues that heal by the formation of poorly organized scar, in fracture healing the original tissue, bone, is regenerated and the properties of the preexisting tissue largely are restored. Fracture healing generally proceeds in an orderly fashion when appropriate biological and mechanical component are present. Many complications may occur with repair and subsequent healing of fracture, including osteomyelitis, implant loosening, and fracture instability. All of these complications may result in delayed union, nonunion or malunion of the fracture.
A 1-year-old male, Collie sustained a closed, transverse femoral fracture in a mortor vehicle accident. His initial treatment with open reduction and bone plating was failed. A second surgery was done to remove the plate and perform corrective osteotomy, and bone grafting. Histopathological observation of the bone fragment from fracture end was carried.
