Silicone adhesive socket technology (liner technology)

The method known as silicone adhesive socket technology or liner technology allows for optimal adhesion of the prosthesis to the amputation stump.

The liner is a distally closed interface made of an elastic silicone material. A screw-in pin on the liner guarantees the fixation of the stump in the prosthesis. When the prosthesis is put on, the pin on the bottom of the socket engages in a corresponding holding device (locking device).

The tight connection between the amputation stump and the prosthesis can be undone by releasing the catch on the locking device.

Supracondylar suspension, as required with the KBM (Kondylen-Bettung-Münster), is not required with the distal attachment. Therefore the supracondylar parts of the socket can be trimmed down to enable the prosthesis to be put on easily.

Liner as an interface

In addition to adhesive socket technology, a liner can be used as an interface for the stump. These liners have no distal connection and are used only as an interface for the stump.

The silicone liners have a thickness of between 1.5 mm and 6 mm. Thicker liners can be made of a silicone gel or a polyurethane with flow characteristics as preferred. The thickness of these liners varies between 3 mm and 6 mm. This method ensures an even distribution of pressure in the prosthesis socket.
