General Fracture Facts in LAs Flashcards
what contralateral limb issues are common after fractures in LAs
equines: contralateral laminitis
bovine: contralateral varus deformity
immature LAs: contralateral angular limb deformity
overall prognosis for LA fractures
guarded to poor
treatment for open fractures
- debride
- systemic/local antibiotics (regional limb perfusion or Ab impregnated PMMA beads)
- cancellous bone graft
modes for local Abs in fractures in LAs
regional limb perfusion
Ab impregnated PMMA beads
LAs require large plates, which can take up a lot of space and make skin closure difficult. where is this especially true? (2)
- distal limbs
- medial aspect of proximal limbs
true or false: LAs MUST be ambulatory immediately following treatment for fracture
true! prone to contralateral limb issues
equines: contralateral laminitis
bovine: contralateral varus deformity
immature LAs: contralateral angular limb deformity
how to describe displacement of a fracture
describe in reference to distal fragment
how to tell if a fracture is open on rads?
radiolucency = gas bubbles
tension band fixation transforms ______ into ______
tensile forces into compressive
purpose of bridging plates
meant to span a defect in bone (which is ideally packed with a cancellous graft)
purpose of a buttressing/antiglide plate
placed to prevent displacement under axial/compressive forces
what angle can screws be placed using a DCP (dynamic compression plate)?
25 degree angle
at what angle can screws be placed using a LC-DCP (limited contract dynamic compression plate)?
40 degree angle (great angle than DCP plates- which are only 25 degrees!!)
type of holes found in a locking compression plate (LCP)
two types!!
conventional: for compression
locking screws: for no compression
locking screws
used in a LCP plate when you do NOT want compression
at what angle are locking screws placed in a LCP plate?
90 degrees
locking screws = no compression
at what angle are conventional screws (cancellous or cortical) placed in a LCP plate?
used for compression
placed at axial angle up to 40 degrees
which type of plate can be placed using minimally invasive techniques
LCP (locking compression plate)
difference between LC-DCP plates used in SAs and LAs?
SAs: narrow with holes in straight line
LAs: broad with holes staggered
most common fracture in LAs
metacarpal/tarsal fractures
