How is bone formation rate measured?
Bone formation rate (BFR/BS, ¼m3/¼m2/day): amount of new bone formed in unit time per unit of bone surface. It is calculated by multiplying the mineralizing surface by the mineral apposition rate.
What is periosteal and endosteal?
The periosteum is a membrane that covers the outer surface of all bones, except at the articular surfaces (i.e. the parts within a joint space) of long bones. Endosteum lines the inner surface of the medullary cavity of all long bones.
What is the function of periosteum?
The periosteum is a complex structure composed of an outer fibrous layer that lends structural integrity and an inner cambium layer that possesses osteogenic potential. During growth and development it contributes to bone elongation and modeling, and when the bone is injured, participates in its recovery.
What is periosteal bone growth?
A periosteal reaction is the formation of new bone in response to injury or other stimuli of the periosteum surrounding the bone. It is most often identified on X-ray films of the bones. Periosteal reaction. Periosteal reaction on a healing supracondylar fracture.
What is histomorphometric analysis?
Histomorphometry is broadly defined as the measurement of the shape or form of a tissue. Quantitative analysis of bone architecture is achieved using bone histomorphometry which provides valuable information on the amount of bone and its cellular activity.
What is the endosteal surface?
The inside surface of bones which border the bone marrow cavity.
What is the structure of periosteum?
The periosteum is composed of two layers: The outer firm and a fibrous layer made up of collagen and reticular fibers and an inner proliferative cambial layer. The periosteum is identifiable on the outer surface of the bone; both layers of the periosteum can be differentiated.
Where is periosteum located?
The periosteum, endosteum and perichondrium are all layers of tissue in and around your bones. The periosteum is the sheath outside your bones that supplies them with blood, nerves and the cells that help them grow and heal. The endosteum is a membrane that lines the center of your bones that contain bone marrow.
