These prostheses are equipped with a knee joint with precisely adjustable brakes.
The benefit of the knee joint is the different strenght of moderation in the different period of walking, thus imitating real walking.
In higher level of activity, the tendency is using multi-axis joint, which also has a significant impact on walking.
These trans-femoral prostheses can be ordered with ankle joints with several level of activity. To choose the most suitable, orthopaedic technician who builds up the prosthesis and the physician who orders the prosthesis have to cooperate.
In the case of trans-femoral and trans-tibial prosthesis, when the stumps state allows it, we can use vaacum fixing, which has a very simple principle. When the stump displace the air from the stump socket, a vaacum spring up and maintain in place the stump.
Wearing this kind of prosthesis is comfortable and safe. |
