Prosthetic Sock
A layered knitted garment worn over the residual limb or liner to manage volume changes and maintain socket fit.
Full Definition
Prosthetic socks are manufactured in standardized ply thicknesses—typically 1-ply, 3-ply, and 5-ply—and are added or removed to compensate for residual limb volume fluctuation throughout the day, maintaining an intimate socket fit. They may be made from wool, cotton, synthetic fibres, or urethane, and are prescribed as part of the prosthetic system. In editorial contexts, 'prosthetic sock' should be distinguished from 'stump sock,' which is an older, less preferred term. The preferred form in modern clinical and insurance documents is 'prosthetic sock,' and editors should update 'stump sock' accordingly unless working with historical records where authenticity is required.
Usage
Usage note: 'Stump sock' is an older synonym; prefer 'prosthetic sock' in contemporary documentation. Do not confuse with 'liner,' which is a roll-on interface device, or 'shrinker,' which is a compression garment used post-amputation rather than inside a socket.
