TSB
Also written as: TSB — Total Surface Bearing
Acronym for Total Surface Bearing, a transtibial socket design in which weight is distributed evenly across the entire residual limb surface rather than concentrated at bony prominences.
Full Definition
Total Surface Bearing (TSB) is a socket interface philosophy predominantly applied to below-knee prostheses, wherein intimate total contact between the socket and all residual limb tissues ensures distributed load transfer and minimised pressure hotspots. TSB sockets are typically used in conjunction with silicone or urethane roll-on liners. In editorial contexts, 'TSB' should always be expanded on first use within a document and followed by the acronym in parentheses. Editors should note that TSB is a socket philosophy, not a suspension mechanism, and should not conflate it with pin-lock or vacuum suspension systems that are often used alongside it.
Usage
Usage note: Expand on first use. Do not confuse with the suspension mechanism employed in conjunction with the socket; TSB describes load distribution philosophy, not how the prosthesis is held on.
In Context
- "The prosthetist transitioned the patient from a PTB to a TSB socket design to alleviate pressure over the fibular head." — Clinical progress note
- "On first reference in the research paper, the editor expanded 'TSB' to 'total surface bearing (TSB)' in accordance with journal style." — Peer-reviewed journal manuscript
