Suspension System
The mechanism by which a prosthetic limb is held securely to the residual limb during use.
Full Definition
A suspension system in prosthetics refers to the method or combination of methods used to maintain the attachment of the prosthetic device to the residual limb during ambulation and daily activity. Common suspension methods include pin/lock systems, suction suspension, elevated vacuum systems, and lanyards. The choice of suspension system significantly affects prosthetic comfort, control, and skin integrity. Editorial documents covering suspension systems include clinical evaluation forms, device comparison studies, and patient outcome questionnaires. Editors should note that 'suspension' in this context does not mean inactivity or cessation.
Usage
Usage note: Not to be confused with the sock or liner; the suspension system specifically refers to the mechanism preventing the prosthesis from falling off during use.
