External coaptation Flashcards
1
Q
indications for external coaptation
A
- First aid/temporary tx of fx
- 2nd support/compression post sx fx repair
- Primary repair of suitable fx
2
Q
main req. for use of cast as primary repair of fx
A
- Fx distal to elbow and stifle joint
- Closed, minimally displaced, inherently stable (good biomechanical)
- Young animal w/ good healing potential (good biologic)
- No complicating factors that could delay healing
- No soft tissue injury
- Heal w/in 4-6wks
3
Q
contraindications for use of cast as primary repair of fx
A
- Fx above stifle/elbow joint
- UNstable fx where adequate reduction cannot be achieved/maintained
- Animals where healing potential is poor
- Open fxs/soft tissue injury
- Healing expected >4-6wks
4
Q
General principles in application of external coaptation
A
- Jt above and below fx immobilised
- Limb should be cast at a standing angle w/ jts flexed rather than extended
- Bone prominences should be adequately padded prior to casting to prevent pressure/friction sores. use ‘donuts’ of cotton wool
5
Q
complications w/ external coaptation
A
- delayed/non/malunion
- jt stiffness (usu self resolving if cast on <4-6wks)
- skin: presssure, friction sores, tissue necrosis, infections
- soft tissue swelling (cast put on too acutely) - first manage swelling for 24-48hs post trauma - then cast
6
Q
ongoing cast care
A
- hospital observation 12hrs post application
- weekly recheck
- fast growing animal change cast q2-3wks
