Q

LAs require large plates, which can take up a lot of space and make skin closure difficult. where is this especially true? (2)

A
  • distal limbs

- medial aspect of proximal limbs

Q

true or false: LAs MUST be ambulatory immediately following treatment for fracture

A

true! prone to contralateral limb issues

equines: contralateral laminitis
bovine: contralateral varus deformity

immature LAs: contralateral angular limb deformity

meant to span a defect in bone (which is ideally packed with a cancellous graft)

Q

at what angle can screws be placed using a LC-DCP (limited contract dynamic compression plate)?

A

Q

at what angle are locking screws placed in a LCP plate?

A

90 degrees

locking screws = no compression

17
Q

at what angle are conventional screws (cancellous or cortical) placed in a LCP plate?

A

used for compression

placed at axial angle up to 40 degrees

18
Q

which type of plate can be placed using minimally invasive techniques

A

LCP (locking compression plate)

19
Q

difference between LC-DCP plates used in SAs and LAs?

A

SAs: narrow with holes in straight line

LAs: broad with holes staggered

20
Q

most common fracture in LAs

A

metacarpal/tarsal fractures
