Q

A bandage is placed over a wound. Day 1 and 2, there is not lameness. Day 3, the patient is lame. What should you do?

A. The patient is sore from procedure, this is normal
B. Patient likely kicked the wall and is now sore, recheck tomorrow
C. Give Bute today and recheck tomorrow if not better
D. Remove bandage and evaluate wound/incision site immediately

Q

T/F: when placing a distal limb bandage, it should not extend past the coronary band

Q

How do you place a stack bandage?

A

Add primary layers as before.

After placing distal secondary layer (cotton sheeting), “stack another cotton roll above, covering the proximal aspect of the first cotton.

Secure with brown gauze

Q

What is a stent bandage

A

Bandage suture over a wound / incision site
“Tie over”

Create suture “loops” to string umbilical tape through secure bandage

Q

When placing a bandage, layers should be applied so tendons are pulled (laterally/medially)?

A

Medially

— minimizes risk of tendon injury secondary to bandage placement

Bandage should be placed from medial aspect of limb, moving cranially, then lateral and caudal

Q

What are the uses of sweat bandages?

A

Decrease edema

17
Q

What can be used to make a sweat bandage?

A

Nitrofurazone ointment (carcinogenic?)
DMSO
Epsom salts

Place on limb then cover with Saran Wrap and support bandage

Remove and wash limb daily

18
Q

What type of splint is often used for phalangeal fractures in horse?

A

Kimzey splints

— stabilize for transprot
—reduce or eliminate flexion/extension of joints

19
Q

What is the name of this bandage?

Has several layers of cotton, size should be 2x the size of the limb

Preserves blood supply and supports fractures

Extends from distal to coronary band to proximal to carpus/tarsus

A

Robert jones bandage

20
Q

What is the most important rule for fracture stabilization?

A

Must immobilize a joint above and a joint below

21
Q

What splint options can you use to stabilize a radial fracture?

A

Robert jones bandage with 2 splints
—> palmar splint from heel to elbow
—> lateral splint from hoof to withers

22
Q

How would you stabilize an olecranon fracture in a horse?

A

Stack bandage with a palmar splint

Extend splint from heels to top of elbow
—> this locks the limb in extension so horse can bear weight (olecranon fracture causes loss of functionality of triceps)

23
Q

When is a Thomas-Schroeder splint appropriate?

A

Radial and tibial fracture stabilization in farm animals
Or rupture of gastrocnemius

NEVER use in horses

Large ring placed around axial or groin, two rods extend cranially and caudally down limb and attach to a foot plate

24
Q

Why do you want to avoid wrinkles in your bandages or casts?

A

Pressure sores

25
Q

T/F: you should never end a cast or a splint in the middle of a long bone

A

True

26
Q

What are indications for casting?

A

Immobilize for..

Laceration 
Fracture 
Transfixation pin casting 
Support for fracture repair 
Soft issue injures (flexor tendon injury)
27
Q

What is the best casting material?

A

Fiberglass casting tape

— light weight, fully set in 5-7mins

28
Q

What are complications of immobilization ?

A

Articular cartilage degeneration

Loss of bone density

Decreased muscle strength

29
Q

What are the steps of cast application?

A

Drill hole in toe of hoof wall and place Gigli wire

Stockinette should be uct 2.5x the length of anticipated cast (foot must be incorporated)

Extra padding at the proximal aspect and around coronary/fetlock region

Incorporate gigli wire in Iv tubing (for cast removal later)

Overlap cast padding and casting tape 50% (no fingerprints/wrinkles in cast —> potentiates cast sores )
Place 2-3layes of casting tape with minimal tension

Elastikon to seal no and bottom of cast

PMMA (Tecnovit) bottom of cast to decrease wear-through

30
Q

Why is it important to incorporate the hoof into the cast for large animals?

A

Ensure maximum diversion of weight from the limb and ground forces alway from the limb to the cast

31
Q

Methods of cast removal?

A

Cast saw
Gigli wire
Cast spreaders

32
Q

How do you evaluate a fracture post-cast removal?

A

Radiographs
—> fracture callus? Or fracture lines present?

Continued stall rest — if fracture stall rest minimum 12 weeks

Bandage placement after cast removal

33
Q

Indications of cast complications or cast failure?

A

LAMENESS

Swelling 
Foul order 
Moisture 
Cracks 
Increased temperature at the cast
34
Q

Common causes of cast failure?

A

Poor placement — abnormal positioning of limbs or pressure pores

Poor owner compliance

Poor animal behaviour

Subsolar abscess

Post op complications

Septic processes under cast

35
Q

How often should a cast be changed?

A

At first sign of lameness

Adults — every 6weeks
Neonates — 7-14days

If there is significant swelling at time of 1st cast placement, change in 3-5days
