Depending on the level and type of amputation you have, we customize each socket to maximize the weight bearing characteristics of your limb. One of the keys to this is choosing the appropriate interface.
The interface is the part of the prosthesis that will be in direct contact with your skin. The newest in technology is not necessarily the most appropriate interface for every patient. We will work with you to find what is most effective.
Historically, amputees have been fit with “stump socks” and a hard socket. Depending on the circumstances this system may be the most appropriate. Materials such as pelite (a closed-cell foam) or kemblo (a durable rubber-like foam) can be utilized to create a softer more adjustable interface.
Silicone liners allow us to use a specific weight bearing socket design. This means we are better able to load and off load areas of your limb. The advantage is that the silicone is able to protect your limb from shear forces that may occur between the socket and your limb. It also helps to distribute forces over a larger desired area. Silicone liners can be used with a sleeve, pin, or seal for suspension.
Thermoplastic elastomer liners allow us to create a total surface weight bearing socket. The theory is that you “float” in the gel and load all areas of your limb therefore decreasing the force in any specific area.
Urethane liners offer the very best in flow properties and have been shown to be the material closest to skin. With this type of liner we use a total surface bearing design. Typically this type of liner is used with an elevated vacuum system to achieve a superior suspension.
