Fractures- Sparks Lecture Flashcards

1
Q

what is the clinical approach to fracture management?

A

what is it, is treatment required, is external coaptation suitable or does it require other forms of fixation or reduction, should i even try to fix it, and how can I give my treatment the best chance of success?

Q

splints are more commonly indicated for______. proper way to put one on?

A

temporary emergency coaptation or as a follow up to other forms of fixation

stabilize the joint above and below, place at 90 degrees, and extend them to the ground

Q

prinicples for proper cast application

A
  • include joint above and below
  • the most proximal portion should end at the end of a long bone
  • include the foot
  • allow limb to be in a neutral position
  • overlap with 50%

Q

what should you consider if you need to do fracture reduction?

A

will probs need heavy sedation since its so painful, use a heavy guage wire through the tip of the hoof, ideally you should have radiographs

Q

pros and cons of a cast

A

pros: cheaper, can be done in the field, good prognosis with some fractures

cons: cast sores, no protection against compression, malalignment of fracture possibly, tendon/ligamrnt laxity

Q

thomas splints are sort of like what in humans? how do they work? when are they indicated?

A

crutches!

specialized splints, idea is to distribute forces with the leg not actually touching the ground i honestly dont know leave me alone fam

mostly for RADIAL & TIBIAL fractures!!

Q

pros and cons to thomas splints

A

pros: cheaper than surgery, can be applied in the field

cons: issues with alignment, what if the fracture opens, can cause prolonged recumbency, pressure sores, contralteral varus

Q

what is transfixation?

A

a cast + external fixator

idea is to suspend the limb in the cast and take weight off the cast tip (idk what this means)

good for fractures that will collapse like long boliques, comminuted, or spiral fractures

17
Q

what anatomical location can be fixed with transfixation pin casting?

A

metacarpals and metatarsals, occasionally the distal radius and distal tibia

DO NOT work for fractures proximal to the radius or tibia

18
Q

pros and cons of transfix

A

pros: can do in GP

cons: pin complications, more technically involved, cast sores, imperfect reduction and alignment, infection,

19
Q

when is external fixation useful?

A

when youre attempting to repair an open fracture–>because you can provide wound care!

20
Q

whaat are some indications for using internal fixation?

A
  • if you want a cosmetic outcome
  • when near perfect reduction is possible
  • in LIGHT animals
  • in an articular fracture?
  • in areas that you can’t reach with other methods (like a femur fracture)
21
Q

pros and cons to internal fixation

A

pros: early return to WB, accurate alignment

cons: expense, referral, implant failure, infection

22
Q

list best way to treat the following fractures:

MC/MT

tibia

radius/ulna

femur

A

MC/MT: cast, transfix if communitied, oblique, ir spiral, and ex fix if open

tibia: thomas splint, cast if distal tibia

radius ulna: thomas splint

femur: ex fix or int fix
