This is information on how to look after your pets cast. The healing of bone takes from six to eight weeks under optimal conditions. A cast is applied to help provide stability to the bone, so that special bone producing cells near the fractured ends of the bone can slowly cement the broken ends together. Movement of the fracture ends will inhibit this healing or even prevent it.
There are several types of cast:
1. Plaster of Paris
2. Synthetic (plastic)
3. Fibreglass
Your pet will generally be under general anesthesia while we apply the cast – this is to prevent any pain, while we manipulate the bones, and so there is no movement while the cast is setting. After your pet goes home he/she will probably be quite sleepy, so don’t give a full meal (1/3 of theri normal meal) and offer plenty of fresh water.
COMMON PROBLEMS ASSOCIATED WITH CASTS:
1.Water
It is of vital importance that casts are kept dry. If they are allowed to become wet this may cause severe damage to the underlying skin. Water will also cause plaster-of-Paris casts to collapse, which will in turn cause instability of the fracture. To prevent water being a problem:
a. Put a plastic bag on the cast when your animal goes outside to the toilet.
b. Don’t let your animal walk on wet grass
c. Don’t let your pet lick the cast – you may need to put a bucket on their head
d. Try to avoid your pet urinating on the cast.
e. Do no bath your pet.
2.Rubbing:
Rubbing can occur anywhere underneath the cast. The top and the bottom of the cast should be checked daily for rub sores. You should also check for any redness or swelling. Keeping your pet quiet can help reduce rub sores. If your pet has not been worried by the cast after application but suddenly start chewing or licking the cast then it is likely there is a sore developing. If this happens it is very important that you bring him/her straight back to prevent further damage. To reduce the chance of rubbing being a problem:
a. Keep your pet as quiet as possible
b. Keep your pet away from sandy areas.
3. Slipping:
If the cast looks like it is beginning to slip then you need to get your pet back to the hospital so it can be checked by the veterinarian. This is important because if the cast has slipped then it will not be providing adequate support to the fracture. To check for slipping check how much toe is present when you first take your pet home; if the toes disappear then the cast has probably slipped.
Growing Animals
Growing animals need to have their casts changed more frequently to ensure they do not grow out of their cast. This means they will need more regular check-ups.
In Summary we recommend:
1. That you do not bath your pet and that the cast is kept dry
2. You confine your pet to a small area (e.g. the laundry)
3. You check for signs of swelling or slipping
4. You return for a recheck when suggested or earlier if there is any damage to the cast or your pet appears uncomfortable.
Good luck with the management of your pet’s cast. We realize they can be difficult to maintain but with your vigilance a good result is more likely. If you have any concerns at all do not hesitate to call the clinic.
