Basic Fracture Fixation Techniques in Small Animals Flashcards
which knot for wire has the greatest resistance to failure?
twist knot
what angle should a cerclage wire be at with respect to the bone it is fixing?
perpendicular to the long axis of bone
what do you need access to for inserting a pin?
medullary canal
why is pinning of the radius not recommended?
high number of complications reported: 70-80%
how wide should a pin be when it is the primary stabilizer?
about 2/3 of medullary canal diameter
what forces does an IM pin neutralize?
only bending
does not address rotational
what does wire neutralize?
compression and rotational forces only in certain fracture configurations
which wire knot can be applied with greatest tension?
loop knot
wire tightened in one step and secured in another
what is normograde insertion?
fracture is reduced first
pin started from bone end, transverse fx site, seated into opposite bone end
what is the easiest fracture to fix?
long oblique
