    Anyone using the rare earth magnet suspension/retention yet?

    I have commissioned a new prosthesis and was discussing suspension methods as I have quite a bit of trouble with my pin/shuttle retention getting stuck on me. I had asked some time back about using magnets and at the time it was not available, but it appears that ****-Bock has worked it out and sent a system into the field using them. I will be the first person with the company I use (CH Martin) to utilize the new system. It is, according to my prosthesist, only good for walking which is the leg we are replacing. My current leg will be slightly modified and become my new riding leg, and my current riding leg will be modified to become my water leg.
    Apparently they have a combination system that uses the magnets and plastic notched pin which hasn't worked well for me in the past, I currently use a smooth pin. I am hoping that the addition of the magnets will do away with the irritating clicking noise while I walk with those systems and why I swapped to smooth. Of course, the notched pins don't get stuck in the shuttle as easily so hopefully it will do away with that issue. Getting a stuck leg off is an art I have become all too good at...

    Sounds interesting. And I don't know how active you are walking. I do a lot of hiking, backpacking, rock scrambling, climbing ladders, hopping fences, hunting, fishing, sailing (which is actually pretty athletic believe it or not) and doing construction work....basically I don't live any differently than before I lost my leg other than being slower and can't go as far or carry as much weight.so I might field the question "how exactly do you define walking".
    they may well be thinking of 80 year old diabetics.
    i tried on a new check socket with my prosthetist the other day, who is also a good friend of mine, and I started doing vertical jumps in the office to make sure I didn't bottom out. Something dawned on me and I asked him if many of his patients did vertical jumps to test fit. He said "no, pretty much I've never even heard of anyone doing that".
    only thing I'm saying is keep in mind that 99.5% of amputees are inactive people. Sometimes it might be worth looking at it the same way you look at technology, being a bit cautious of being an eearly adopter. Read up on the tech and if it seems like it will fit your needs, and you don't feel like if it's a bad choice you are stuck with it, go for it. It's the only way things get tested.
    of course I have to admit I'm biased. I'm by nature leery of really new stuff, and I may subconciously just be wanting to see someone else use it before I go begging for one.

    So how do you release from a magnet?

    Seems like if you still have a pin, and a hole in the bottom of the socket, then if it doesn't work well the it's a fairly easy switch back to a pin lock?

    I have been using the same prosthesist for my entire time as an amp. We communicate very well and he knows my fit/activity level so in that I am not concerned that I would do too much. As to how it releases, I can't say yet cause I just don't know.
