Slideshow Project DOI: /JRRD JSP Aim – Assess static failure loads for check sockets (CSs), copolymer sockets (CPs), and definitive laminated sockets (DLs). – Compare facilities, fabrication material and methods, and socket thickness. Relevance – While International Organization for Standardization (ISO) standards exist for most lower-limb prosthetic components, they do not include prosthetic sockets.

Strength evaluation of prosthetic check sockets, copolymer sockets, and definitive laminated sockets. J Rehabil Res Dev. 2012;49(3):405–26. Slideshow Project DOI: /JRRD JSP Methods We used modified ISO to measure static failure loads of prosthetic sockets. – Compared them with criteria set by this standard for other components. Static socket testing configuration.

Slideshow Project DOI: /JRRD JSP Results CS Static Strength – Influenced by thickness, material choice, fabrication method. CP Static Strength – Depended on thickness, fabrication method. DL Static Strength – Influenced by material choice, fabrication method. Ductile loading criterion: – Most CSs and all CPs failed in a ductile mode. Brittle loading criterion: – Most DLs failed in a brittle mode.
