Implant for surgery — Test method for torsional strength of porous calcium salt bone void filler after preconditioning in deaerated phosphate buffered saline

Scope

This document specifies the test method to be followed for measuring and documenting the torsional strength of calcium salt based bone void fillers after preconditioning in deaerated phosphate buffered saline to mimic in vivo circumstances. This document can be applied for all calcium salt based bone void fillers including non-porous ones after appropriate inter-laboratory tests.
This document applies to porous calcium salt based bone void fillers with a total porosity ratio of 50 % to 90 % and an average size of macropores of 1 μm to 500 μm as measured by methods described in ISO 13175-3.
