Suspension System
The mechanism or combination of mechanisms that secures a prosthesis to the residual limb and prevents it from slipping or falling off during activity.
Full Definition
A suspension system encompasses all components and methods used to maintain the attachment of a prosthesis to the residual limb throughout the wearer's range of motion. Common suspension strategies include pin-lock liners, vacuum-assisted socket systems (VASS), suction sockets, lanyard systems, and auxiliary suspension sleeves. The choice of suspension system is influenced by activity level, residual limb volume stability, skin condition, and patient preference. Editors should be aware that 'suspension' alone is frequently used as shorthand in clinical documentation but may require clarification in consumer-facing or regulatory texts.
Usage
Usage note: When editing, clarify the specific type of suspension system rather than leaving the term unqualified, especially in clinical outcome studies.
