HIGH YIELD Flashcards
the benefit of AAFAO?
atraumatic technique fracture pattern bone quality fixation method post op mgmt protected weightbearing pt selection/compliance
what are the original AO principles?
restoration of anatomy
stable fracture fixation
preservation of blood supply
early mobilization of the limb and patient
purpose of anatomical reduction?
restores full function
re-establish
purpose of rigid internal compression fixation?
adequate stability to maintain
what is the purpose of atraumatic surgical technique?
preserves the surgical technique
what is early pain free motion?
fracture/cast disease
what are the 21st century AO principes?
fracture reduction and fixation
provides absolute or relative stability as personality
preservation of blood supply to the soft tissues and bone by gentle reduction techniques, careful handling
early and safe mobilization and rehab
what are the types of biomechanical stability?
absolute stability
relative stability
name this type of biomechanical stability?
primary bone healing
compression plate and screws
articular fractures require anatomical reduction and absolute stability to enhance healing
absolute stability
name this type of biomechanical stability?
secondary bone healing
intramedullary nail
external fixation
bridge plating using the internal fixator principle
relative stability
indirect bone healing occurs during what kind of stability?
relative stability
- casting
- traction
- tx
- IM nailing
- bridge plating
- external fixation
what kind of healing is seen for absolute stability?
direct bone healing
primary bone healing
no callous formation
direct osteonal remodeling (cutting cone)
only in absolute stability
direct bone healing
for bone healing, absolute stability is what kind of bone healing?
minimal callus
primary bone healing
for bone healing, relative stability is what kind of bone healing?
callus
2econdary bone healing
