Here are the responses to my questions regarding children’s chopart
foot/feet. Thanks everyone.
1. The otto bock chopart style foot works well and bonding is not an issue
just follow the instructions provided. If you have enough room you can also
use Childs Play foot or a College Park Truper foot. I have used them both
on Symes patients.
2. I know the times I used otto bock chopart feet you have to make sure that
they are bonded correctly are you can have problems. The L codes otto
bock recominds just covers the cost of the foot. Good luck , PS I used
rapid cure to attach to the check socket.
3. If you want to both protect the residual foot and restore dynamic
propulsion to gait, fabricate a socket for the foot and mount that on a
Kiddie
Gait to replace the lever arm lost to amputation. You’ll get the best of
foot preservation (no callus formation) and gait restoration (propulsion).
4. Otto Bock is your best option. I recommend laminating it in. Maybe a
couple SS rivets. Every Urethane bond I have ever seen rips off.
5. We have used the Otto Bock Chopart plate a number of times. I have
bonded the check socket to the plate with two part epoxy. You can reinforce
with fiberglass and walk patient without the footshell (use crepe or
cloud temporarily). I am assuming the child is a congenital syme or boyd
amputee. Do you have room to modify child’s play foot and do a stirrup
lamination.
6. I have used this on adults several times. I had bonded the plate directly
on the check socket with segalhartz resin/sucaflux mixed which is a fine
wood powder. Mix like a paste. They can walk on this for alignment
purpose but excessive walking. As for the code, I believe you can only use
5976
energy storing foot for the Chopart foot plate.
7. I have just recently fabricated such a device. We tried the Otto Bock
urethane / carbon foot to no avail. We ended up using a composite foot
(not carbon) OWW I think. We bonded the foot with epoxy and laminated
with carbon strips and braid over the bottom of the foot. This added a
little
height (approx.1/4″). This was approx. 4/5 mths ago and the patient is
doing well.
Re: issue with OB bond breaking:
I spoke to OB on this same subject and was told they have the same
problems I spoke of and ended up laminating over the bottom of the foot as I
did.
Their urethane bonding only works about 60% of the time in my
experiences. I’ve tried this a number of times.
As far as bonding to the Tst skt, I would use a 2 part epoxy and wrap
with fiberglass casting tape. Remember to leave approx. 1/8 in between
distal socket and top of foot to allow bonding between skt and
footplate. To remove just cut off tape and use some heat to soften epoxy and
it
should peel off.
I can’t give you any coding recomendations, that is not my area.
I am researching the foot plate manuf. and will get back to you when I
find it.
