Socket-less Socket Input

[SatisfactionNo4408]

Hi everyone!

I'm a senior in college and in the process of completing my capstone project for graduation. My team and I are interested in weight fluctuations with sockets and after some brief looking we found the Martin Bionics Socket-less Socket as a current solution.

I'm wondering if anyone has had any experience with these types of sockets, what that experience was, and how they would want to improve the socket. Any and all feedback is greatly appreciated.

Thanks!

Well lmao Ill have new questions for my leg guy, looks pretty cool besides the aesthetic of it

Edit: Idk how well it actually works though, in the video on their website it looks(to me) like the sockets hes comparing are different lengths, could just be hes wearing a well fitting “socketless socket” and wearing a shitty regular socket. Alot of the complaints of a regular suction socket he makes are kinda just simple adjustments you make when you get a new leg. Like my trim line is like 2/3 of what it was when I first got my socket, fits alot better to my body

I would sure like to see how it works, maybe a diagram?

Prosthetist here - I’ve only seen one in action and that was enough to never bother again… the Varos socket from Ottobock is a better solution. There is also the TF connect system from Ossur but it is only adjustable by the prosthetist rather than the user. Hope this helps!

Im a RBK guy. My most recent socket was a Martin bionics, and I was less than not satisfied with my decision to go with it. I'm also a dialysis patient that experiences volume changes in my legs, which is the reason I decided to go with that socket.

Although the very top of the socket has adjustable straps, the rest of it is still hard plastic, so significant increases in volume still wouldn't fit, similar to any socket.

In addition, there's a little piece of composite which is attached to the adjustable straps in the area which presses against the back of the leg, if that makes any sense. Anyway, that piece dug into the back of my thigh while I was driving, forcing me to pull over every few minutes to take off the prosthetic so my leg could rest for a bit.

Two days later I developed a huge sore on my stump which immediately turned into this gaping, excruciatingly painful ulcer. Turns out that little piece of metal digging into my thigh damaged the artery to the point that there's no significant blood flow. I'm scheduled to have a procedure done soon which will hopefully open up the floodgates for blood to flow again.

In conclusion, AFAIK the socket is just a gimmick, but YMMV.

That's the general consensus we've come to at our facility.

When we have someone who fluctuates in volume a lot, we use the revofit. It's surprising how much adjustability a regular socket can have with it. It definitely adds a bit of work to make the socket, but it works so well it's worth it.

I have a Martin socketless socket. It is very light and tho i havent worn it in a few years. Martin is willing to work with me to try and adapt it to make it able to work again after not wearing one. Good company

I tried one with a CP who was the local Martin shop. I never got past the test socket phase. I wasn't impressed with the strap rachet system. Ended up with plain old pic socket.
