Bone Biology and Fracture Healing Flashcards
what are the functions of bone?
How much of the dry weight of bone is mineral?
Describe flat bones, cuboidal bones, and long bones
How do equine long bones have a mechanical advantage compared to other species?
What structures are created durding appositional bone growth?
what type of bone growth results in increased bone thickness?
appositional bone growth
Describe cortical bone
Describe periosteum
Describe cancellous/spongy/trabecular bone
which layer of the periosteum is metabolically active and responsible for fracture healing?
Inner cambium layer
what is this?
Load-deformation curve
Describe elastic region and plastic region
elastic - bone maintains capacity to return to its original shape after removal of load
plastic - bone will not return to its original shape when load is removed
what is the yield point in a load deformation curve?
end of elastic deformation
how is stiffness calculated in load-deformation curve?
slope of curve in elastic region
what is biologic fracture healing?
physiologic process that forms callus to bridge fracture site
what is structural fracture healing?
related more to what is physically done during surgery
what are the 3 stages of biologic fracture healing?
inflammatory phase
repair phase
remodeling phase
Descrive the inflammatory phase
Descrive the repair phase
what is the longest phase of fracture healing?
remodeling phase
