Re: BK question

With regards to a vertical shock which is lighter than the VSP, virtually

any others on the market will be lower in weight. I personally prefer to use

the Century XXII shock/torque absorber. It’s light weight, compact, and yes

with the proper components you can use just aout any foot with it. You can

also change the compression/torque by simply changing out the plastic

bumpers. Look into it.

Subject: BK question

A retired, sixty something, plays with grandchildren, prosthetic client

who is new to me came in for an evaluation. He is currently wearing a

Flex Foot VSP system attached to a laminated socket with pelite

liner/plastizote end pad and 5 ply wool sock and no cover. His distal

tibia is approx. 1/2 inch longer than the distal soft tissue. I imagine

that walking around on this would be like walking on ones elbows.

Painful. Yes, he states that after about three minutes he is hurting.

Aside from that his skin looks good so the liner and fit appear fine.

The VSP acts like a strut not a shock. He did not know the thing was

supposed to cushion each step. So actually providing a shock pylon may

be a godsend for him. However, I have concerns about weight weighed

against comfort.

Is there a vertical shock pylon lighter or simpler than the VSP?

Does it accept pyramid alignment connectors?

Can any foot be attached?

Any thoughts on roll-on suction liners with and without shuttle lock for

such a distal end? My concern is that the cup of the pinned liner may

add an unwanted load upon the tibia, but a suction liner requires

additional sleeve to attain suction which adds weight and probably added


Responses will be forwarded to the list in one message with author’s
