Test Socket
A transparent or semi-transparent provisional socket fabricated to assess fit, alignment, and tissue loading before the definitive socket is manufactured.
Full Definition
A test socket (also called a check socket or diagnostic socket) is typically made from clear thermoplastic material, allowing the prosthetist to observe tissue contact, pressure distribution, and potential problem areas during weight-bearing and functional activities. The test socket phase is a critical step in the fabrication process, documented in clinical records prior to authorisation for the definitive socket. Editors must distinguish 'test socket' from 'preparatory prosthesis', which is a complete temporary device rather than a diagnostic fitting tool. In insurance documentation, the test socket may require separate justification. The term is typically written as two words without a hyphen.
Usage
Usage note: Write as two words: 'test socket'. Avoid 'check socket' in formal documentation as usage varies by region.
