Inner prosthetic socket

The prosthesis socket is the connection between the stump and the prosthesis and performs an important function: it ensures a good hold and good seat for the prosthesis.

The prosthesis socket consists of two parts: a soft inner socket made of SIMOLIFE EVA flex, which embeds the amputee’s femoral stump and a rigid but light carbon-fibre brace that assumes the weight-bearing function of the socket.

The interior socket made of SIMOLIFE EVA flex or EVA superflex is flexible at the edge and therefore movements such as sitting down are not significantly impaired.

The carbon-fibre socket performs the weight-bearing function of the socket and creates the connection to other parts of the leg prosthesis (knee, foot).

The C-Leg® system*

The C-Leg® is a hydraulic leg prosthesis system that includes a microprocessor to control the entire gait cycle, from standing to walking.

The sensors integrated within the C-Leg® knee joint monitor the wearer's gait pattern and make real-time adjustments in accordance with his or her walking speed, step length and frequency.

Whether standing on an incline, walking on uneven ground or using stairs, the high-performance leg prosthesis system automatically adapts to the situation and thus combines the very best in mobility with superior safety.

The adapter

The adapter connects the knee joint with the socket.

Wearers can choose specific types of functional adapters for added mobility, safety and comfort. For example, a rotation adapter can be used to swing the prosthesis to the side when driving.

The hydraulic unit

The hydraulic unit controls the C-Leg®.
It generates the resistance needed for flexion and extension in the stance and swing phase.
