Bracing a Baby Bunny with "Splay-leg"

Some rabbits are born with a condition known as "splay-leg," in which the
front legs, hind legs or all four legs splay out to the side like little
seal flippers. Although most experts believe that the condition is
congenital (possibly due to genetics resulting in weak connective tissue),
it can be exacerbated by environmental conditions, such as
being raised on a slippery floor that gives no traction.
A 100% cotton, textured bathmat surface for
playing and exercising as soon as babies come out of the nest may help
reduce the incidence of splay-leg.
Splay-leg bunnies can usually move about with a flopping
motion, and we do know of completely happy adult "splay-leg" bunnies who
can race about the house very quickly. However, because these bunnies tend
to develop other health problems, it isn't a bad idea to try to correct
the problem when it is first detected, in very young babies about 3-5 weeks
of age. Whatever the cause of the problem (nature or nurture), in some
cases it can be corrected if the babies are fitted with simple, home-made
leg braces, as illustrated below.
The brace itself consists of nothing more than
a natural cork from a standard wine bottle, cut to about 1" long
two 100% cotton pads, slightly larger in diameter than the cork, and
about 1/4 inch thick
breathable, adhesive sports tape
Here's an exploded diagram of the positions of these components as they
will be assembled between the bunny's legs:

Diagrams below show how to brace a bunny's front legs.
Very
gently pull them to normal position, and place the cork, with cotton pads
on each end, against the bunny's wrists, or slightly higher.
- Note that if the legs are severely splayed, and do not readily come
together without causing the bunny pain, you may have to start with a longer
cork, and gradually (every few days) unwrap the brace, cut it a bit shorter,
and re-wrap.
While you're holding the brace and bunny, have another person
carefully wrap a loop of the sports tape completely around the legs and
brace.
- MAKE SURE THE TAPE IS NOT TOO TIGHT! If it's too tight, circulation
will be cut off, and the situation will be worse than before. This is the
trickiest part of the operation, since if the tape is too loose the
brace can slip off. You may have to modify the taping areas to accommodate
individual rabbits. Improvise and improve!
Successfully assembled, the brace should allow the bunny to stand, though he will
(at least temporarily) not be able to move the front legs independently.
Although the bunnies tend to be very upset at first, and may struggle,
they get used to the contraption anywhere from a few hours to a day or two
after you've strapped it on, and begin to learn to hop in "tripod" fashion.
Here's what a front-leg brace looks like, from top view and from a somewhat
oblique view:


Back legs are more tricky. You'll use the same set-up and procedure as for
the front legs, but position the brace just above the hocks (ankles).
Bunnies are not fond of having their back legs braced, and they will
struggle. But again, they do tend to get used to it within a few hours,
and start to learn to hop.
For back leg braces, be sure you don't obstruct the urethral opening
or anus with tape or padding! Also check frequently to be sure the padding
and/or tape do not become soiled with urine or feces. If this happens, a
mild rinse, thorough drying and re-bandaging will be necessary to prevent burn to the
delicate skin.
Here are a couple of drawings showing how the
back leg braces should be attached:


Caveat lector: I have never tried to use these braces on a rabbit with all four
legs splayed, so I am not certain how well this would work. Still, It might be
worth a try. If the bunny seems very stressed, it would probably be best
to do one set of legs at a time, perhaps starting with either the front or
the back, and waiting to brace the other set until the bunny becomes
accustomed to the first brace. The cure should not be worse than the
disorder!
GOOD LUCK!
