Silicone Liner
Pronunciation: SIL-ih-kon LY-ner
A flexible, body-conforming sleeve placed directly over the residual limb to provide cushioning, improve socket fit, and facilitate suspension of a prosthetic device.
Full Definition
A silicone liner is a prefabricated or custom-fabricated elastomeric sleeve rolled onto the residual limb before donning the prosthetic socket. It serves multiple functions: distributing pressure evenly across the limb surface, protecting delicate skin, reducing shear forces, and providing a mechanism for suspension—either through a pin-lock, locking lanyard, or suction. Liners are available in varying thicknesses, durometers (shore hardness), and materials including silicone, polyurethane, and thermoplastic elastomers. Editors should note that 'silicone' (the polymer) is frequently misspelled as 'silicon' (the element); this distinction is a common editorial error in prosthetic documents.
Usage
Usage note: Critical spelling distinction: 'silicone' (polymer material used in liners) vs. 'silicon' (semiconductor element). The wrong spelling invalidates clinical accuracy. Always 'silicone liner,' never 'silicon liner.'
