Prosthetic Interface
Any material or device interposed between the residual limb and the prosthetic socket to manage pressure, friction, and suspension.
Full Definition
The prosthetic interface encompasses liners, socks, sleeves, and other materials that mediate the mechanical and thermal relationship between skin and socket. Proper interface selection is critical to preventing skin breakdown, managing volume fluctuation, and achieving suspension. Editors should note that 'interface' in prosthetics is a technical term with a specific meaning distinct from its generic use; it should not be loosely substituted with 'padding' or 'lining'. Gel, silicone, and urethane are the most common interface materials, each documented by material type in the clinical record. The interface system is often described separately from the suspension system, though the two are functionally interrelated.
Usage
Usage note: Qualify with material type (silicone, gel, urethane) for precision; do not use as a synonym for 'liner' without confirming the clinical context.
