Silicone Liners with Locking Mechanism
The silicone liners provide optimal suspension of the prosthesis on the residual limb.
The liner is a distally closed interface made of an elastic silicone material. Suspension is obtained
through a pin which is inserted in a locking device placed distally within the socket.
The pin can be unlocked to loosen the liner and doff the prosthesis.
Supracondylar suspension is not required when the liner/pin technique is used. Therefore, the socket
can be trimmed down to allow easy donning of the prosthesis.
This prosthetic design improves the patient‘s feedback and gives a safe feeling during ambulation.
Liner as Interface
Additionally, liners can be used only as an interface without the suspension feature. These liners do not
have a distal attachment.
These silicone interfaces have a thickness between 1.5 mm and 6 mm. Thicker liners can be made of a
silcone gel or a fluid-like polyurethane to achieve an even distribution of pressure over the residual limb.
Through this technique the patients feel comfortable, specially those with bony, scarry other extremely
sensitive residual limbs.
