Total Surface-Bearing Socket
Also written as: TSB — Total Surface-Bearing Socket
A socket design in which the entire residual limb surface bears weight uniformly, rather than loading only bony prominences.
Full Definition
A total surface-bearing (TSB) socket distributes prosthetic load evenly across the entire residual limb interface, reducing peak pressures on bony prominences and improving soft-tissue health. It is typically used in conjunction with a roll-on liner that provides total contact. Editors should note the abbreviation TSB, which already appears on many existing-terms exclusion lists — when 'TSB' appears in documents, confirm that it refers to 'total surface-bearing socket' rather than being confused with 'total surface bearing' alone. Distinguish from the patella-tendon-bearing (PTB) socket, which loads specific anatomical landmarks.
Usage
Usage note: Hyphenate 'surface-bearing' as a compound modifier. The abbreviation TSB is widely used but may conflict with other clinical abbreviations; define on first use.
In Context
- "The total surface-bearing socket design was selected to minimize distal end pressure in a patient with fragile residual limb tissue." — Prosthetic evaluation report
- "Editors must distinguish 'total surface-bearing socket' from 'total contact cast,' which is a wound-care device, not a prosthetic component." — Editorial style note
