The Sockets

We have the choice between two socket heights.

The High Prostheses

They go up to the knee and can be made with or without a posterior part:

  • The prosthesis with a high posterior part: the person puts a copolymer liner over the stump and fits it directly into the socket. The retention of the prosthesis is achieved through the webbing at the back in the posterior part. Special attention should be paid when putting on the liner, which is quite fragile.
  • The high prosthesis without posterior part: using a foam sleeve of the podo foam kind over the area to offset reduced circumference. This produces a uniform cylindrical shape. The patient slides into the contact socket. This technique is simple and reliable.

These high prostheses have the characteristic of  increasing the  arm leverage for better stability when walking and a better follow through of the step.

The Low Prostheses

Can be of several kinds:

  • A low shell in semi-rigid material bonded to a prosthetic foot
  • A silicone foot from either Otto Bock or PROCOSIL.

The Otto Bock silicone foot is one with the person, the color is dyed throughout. The silicone is relatively rigid and heavy but very solid.

The PROCOSIL silicon foot is moulded onto the person, the color is customised (the color is compared to the opposite foot).The silicone is flexible.
We have in both cases the shape of the toes.

The aesthetic result is indisputable, but this kind of prosthesis requires good stability of the distal stump and a good muscle strength.
