Factors that may disrupt normal fracture healing include all except: - ANSWER✔✔-

Internal fixation immobilization


The interior of a vertebra consists of what type of bone? - ANSWER✔✔-Trabecular


A fracture in which the bone is in normal anatomical alignment - ANSWER✔✔-Simple


How would you describe this type of fracture (Rotary)? - ANSWER✔✔-Spiral


What type of fracture is this? (Bloody) - ANSWER✔✔-Open


What type of fracture occurs as a result of nutritional deficits? - ANSWER✔✔-Trophic

,Osteocytes - ANSWER✔✔-Mature bone cells


Osteoblasts - ANSWER✔✔-A cell that manufactures


Osteoclasts - ANSWER✔✔-A bone cell which breaks down bone matrix


Trabecular (Cancellous bone) - ANSWER✔✔-Type of porous bone having large

latticework and a spongy, honeycomb appearance; filled with marrow


Matrix - ANSWER✔✔-the microscope substance of a tissue or cell. Intercellular

substance of cartilage, produced by cartilage cells


Compact (cortical) bone - ANSWER✔✔-dense hard layer of bone making up outer

surface of long bones; surrounds spongy trabecular bone


Cancellous (trabecular) - ANSWER✔✔-refers to the inner layer of bone that has a

porous, lattice-like, spongy structure


Periosteum - ANSWER✔✔-Divided into 2 layers. New blood cells are produced in the

inner layer of the periosteum. Nerve and blood vessels within the periosteum provide

nourishment for the underlying bone, but not sufficient to provide all the nourishment

needed by the bone cortex. Periosteum also helps protect the bone from infection.The

, Normal bone healing - ANSWER✔✔-A fractured bone should normally heal within 8 -

12 weeks. To ensure good healing, the fracture should be:


a. Properly aligned


b. Immobilized by internal or external fixation


Stage one of normal bone healing: Inflammation - ANSWER✔✔-The inflammation stage

of healing lasts about 2 days. A blood clot, called the hematoma is formed.


Stage two of normal bone healing: Cellular proliferation - ANSWER✔✔-The cellular

proliferation stage begins on the second day post-injury. Macrophages debride the

injured area. A fibrin mesh is produced which seals the edges of the fractured bones.

The fibrin mesh allows capillary and fibroblastic ingrowth. Fibroblasts and osteoblasts

form a periosteal callus.


Stage three of normal bone healing: Callus formation - ANSWER✔✔-The callus

formation stage continues for 3-4 weeks. During this stage, the bone fragments grow

together.


Stage four of bone healing: Ossification - ANSWER✔✔-The ossification stage lasts 3-4

months. The new tissue calcifies.


Stage five of normal bone healing: remodeling - ANSWER✔✔-The remodeling stage is

normal bone maintenance
