Total-Surface-Bearing Socket
Also written as: TSB — Total-Surface-Bearing Socket
A socket design in which pressure is distributed uniformly across the entire residual limb surface rather than concentrated at specific load-tolerant sites.
Full Definition
The total-surface-bearing (TSB) socket philosophy holds that uniform distribution of compressive forces across all available soft tissue reduces peak pressures, improves circulation, and enhances comfort compared with earlier selective-loading designs. TSB sockets are most commonly paired with silicone liner suspension systems. Editors should note that 'total surface bearing' as a noun phrase is unhyphenated, but 'total-surface-bearing' as a compound modifier before a noun is hyphenated. The abbreviation TSB appears frequently in insurance documentation, peer-reviewed prosthetics journals, and evidence-based clinical guidelines.
Usage
Usage note: Hyphenate as 'total-surface-bearing' when the phrase precedes a noun. Expand 'TSB' on first use in formal documents.
