Bone Grafts (Dr. Dayton) Flashcards
What is the most important component in regards to bone healing?
vascular system
- good circulation is important
What does a bone graft provide?
scaffold for bone growth
What is the process in osteogenesis?
- induction of bone growth by protein growth factors
What is osteostimulation?
provide external forces that can up-regulate healing (electrical or chemical)
What is an autograft?
taken from patient
What is an allograft?
taken from another human
Which two grafts make up most of the bone grafts?
autograft and allograft
What is the best type of bone grafts?
patient’s good bone (living)
- problem is finding good amount
What are some places bone grafts can be taken from in a patient?
iliac crest (hip) proximal tibia distal tibia segmental fibula calcaneus local bone at surgical site
What is required for bone to heal?
- vascular system
- cellular activity
- mechanical stability
- healthy patient immune system
What is the function of bone graft?
- structural support
- void filler
- improved healing
What are healing characteristics?
osteoconduction
osteoinduction
osteogenesis
osteostimulation
What are composite grafts?
combine both
Why is bone marrow used?
contain cells and proteins that increases local cellular activity, improving healing
What an example of a composite graft?
B-tricalcium phosphate + autogenous bone marrow
scaffold+cells+proteins = better healing (biggest thing is it’s recognized by the body as a place of healing)
