Dear Members,

Please, assist me with the following:

Bilateral BK, 40 y/old, currently uses Alpha Locking liners, VSP-s.

He wants to have Swim prostheses with ActiveAnkles. He also would prefer

to keep the roll-on liner suspension. No preference as far as endo or exo.

Cosmetic appearance is of no concern. I made quite a few swim/shower

prostheses –

hollow exo, PTB-SC, ActiveSleeve, CC2 foot. I also used ActiveAnkles but

many years ago (when they originally were introduced). Now, here are my


1. Did anybody have experience using roll-on suction sockets for “water

prostheses”, if yes, then what kind of shuttle lock (I would speculate, that

The Pin would work better, as there are fewer moving parts). Were there

corrosion problems etc?

2. ActiveAnkle originally wasn’t very easy to operate, as the dial would get

stuck, because of sand, salt etc (even with the neoprene sleeve). I knoe there

is at least one more design. Who makes it? What are your comments?

3. If you choose endo design, what are your suggested components?

4. Any suggestions how to bill for the ankle unit?

Thank you all in advance for any assistance.
