Liner
A soft, flexible sleeve worn directly over the residual limb to provide cushioning, suspension, and a stable interface between the limb and the prosthetic socket.
Full Definition
A liner is a prefabricated or custom-fabricated sleeve, typically made from silicone, polyurethane, or thermoplastic elastomer, that is rolled onto the residual limb before donning a prosthetic socket. It serves as the primary interface layer, distributing pressure, reducing shear forces, and improving skin integrity. Many liners incorporate a locking pin or lanyard at the distal end to provide suspension of the prosthesis. Editors should note that 'liner' is distinct from 'sleeve,' which is an external suspension component. The correct plural is 'liners,' and it is lowercase in running text.
Usage
Usage note: Do not capitalise 'liner' in general running text. Distinguish from 'sleeve,' which is a separate suspension component worn on the outside of the socket.
