12 - Fracture Classifucat Flashcards
Descriptive classification
Extent, soft tissue integrity, type, where, how ,which bone, and displacement
Incomplete green stick fracture
Young animal, bone bends and breaks distal aspect, and bends proximal aspect
2 ways to describe incomplete fracture
Greenstick or fissure
Soft tissue integrity closed
No contact of bone to exterior
Type 1 fracture results from
Low energy force
Soft tissue wound of 1 cm is what what type fracture
Type 1
Type 1 is most common in
Radius ulna and tibia
Type 2 fracture results from
High energy forces
Type 2 the wound is how big
Greater than 1 cm
Extensive soft tissue loss is what type
Type 3B
Pedro steal stripping and bone exposure is what type
3B
With a type 3B may need what for closure
Local or free skin flap for closure
How is 3B different from 3c
Arterial supplied damage is in 3C
Transverse fracture has an angle of
Less than 30 degreee
Transverse fracture is perpendicular to
Long axis
Short oblique fracture angle
30 -60
Long oblique fracture angle
Great than 60 degrees
With long spiral fracture your X-rays will show
Center of the bone
Comminuted fracture
More than 2 fragments
Epiphyseal location
Proximal or distal to physis
Metaphysical location
Wide part between epiphysis and diaphysis - contains the physis
Diaphysis
Narrower tubular shaft of bone between the metaphyses
Apophysis location
Separate ossification center
Traction epiphysis aka
Apophysis
Where location on the bone is called
Salter and Harris
Only use salter Harris with
Open physis
Salter 2
Piece of metaphyseal bone
Salter 3
Partial fracture and displacement of growth plate plus fracture of cartilage
4 causes of fracture
Trauma, pathological, stress protection, fatigue fracture, defect in bone
Radiolucent fracture lines can be mimicked by
Nutrient foramen, overlying fascia plane, skin defect, normal growth plate, Mach line
Mach line
Dark lines along edge of 2 overlapping bones due to an optical illusion
