“Suspension” is the term used to describe how the prosthesis “suspends” or connects to the residual limb.
The most common methods of suspension incorporate some type of gel liner to pad the limb and reduce friction within the socket. Gel liners have revolutionized the field of prosthetics, introducing added cushioning, more comfort and enhanced connection of the prosthetic limb to the amputee.
There are hundreds of prosthetic liners to choose from, made with different materials, fabrics and features. Many gel liners even incorporate Aloe Vera and other minerals to rejuvenate and moisturize the limb.
Landyard Locking Liner
A lanyard locking liner has a Velcro strap connected to the bottom of the liner that is fed through passage in the prosthesis. This strap is then looped through a buckle on the outside of the prosthesis and secured (using heavy duty Velcro) to hold it into place. This is a secure and simple suspension solution for above the knee amputees.
This simple system has a pin locking liner connected to the gel liner that “ratchets” into a lock inside the prosthesis. This solution is great for below the knee amputees because you can hear the clicks as the pin engages with the lock and knows that the prosthesis is secure and safe to walk. A small button is depressed to disengage the lock to take the prosthesis easily. This system works well for many transtibial amputees and does not require the use of a knee suspension sleeve.
