Responses: Socket Options

Dennis Farrell, CP

Dear list, my original post is below as well as the 2 responses I
received. I was disappointed that only one practitioner who has actually used
either of the systems replied. All of the other messages were requests for me to
post the results.

Any additional responses would still be welcomed and again I will post
those as well. Thanks!


Original post: “I would appreciate input from any members who have had
experiences with the ‘Socket-less’ socket by Martin Bionics or the ‘Infinite
Socket’ by Lim Innovations.

I have a couple of transfemoral patients interested in exploring these

Any insight or advice, both positive and negative would be greatly


I just tried one on a KD 20 year old and after 3 weeks of trial, he decided
it was not for him. He didn’t like the bulk or the actual fit. It
seemed promising at first and he was very excited as he decided that this socket
would give his leg the ability to “grow” his muscles and not confine them
as much as a conventional socket does. This patient ice skates (goalie),
weightlifts, has run in a mud run locally and was looking for something
cutting edge.
I had a large learning curve with fitting the socket. Jay from Martin was
very helpful but it would have been better to have some hands on training
as their training video online isn’t detailed enough, or just wasn’t enough
for me.

Hey Dennis, if you came to the PacRim in Kauai in Jan you would have seen
them side by side. The concepts of both are very similar. The Infinite is
a custom made, central fab, prepreg frame; the Martin Bionics is a frame
you assemble in your lab. Big selling point is the daily adaptability and
more sitting comfort. The compression of the frame helps maintain
rotational stability. I was impressed by both in HI and took the LIM course @ AAOP.
IF I was still in clinical practice I would consider using either one,
depending on the amputee’s cognitive ability.
