Exam 2 Pt. 1 Flashcards
Transverse Fracture
run at right angles to the long axis
Usually direct blows or tensile forces
common in pathologic conditions
Oblique Fracture
45 degrees to the long axis
results from angulation or + compression
may have small transverse component
Spiral fracture
encircles shaft and is longer than oblique fx.
Results from torque and axial compression
ends are pointed like a pen
Apposition is
the relation of the bony fragments in relation of the distal fragment relative to the proximal
When the apposition does not match what do we call it?
offset
what is alignment
position of the distal fragment in relation to the proximal in the LONGITUDINAL axis
Rotation is most easily determined by
clinical evaluation over radiograph
Salter H 1
complete shear injury of the physis
Salter H 2
fracture through physis and metaphysis
Salter H 3
Fracture physis and epiphysis
Salter H 4
fracture of the physis, metaphysis, and epiphysis
Salter H 5
compression fracture of the physis
what is the MC Salter Harris
Type 2
Rates of fractures in males
highest rate in 2nd and 3rd decade then decrease by 45, then raises after 65yrs
rates of fractures of females
highest up to 20yrs and decreases to 45, where it begins to steadily increase
