From: Which experimental procedures influence the apparent proximal femoral stiffness? A parametric study
1. Fresh frozen specimens aligned, cut, and potted in neutral stance position, 2. Clinical CT scan of the samples (data not presented, acquired for another study), 3. The first set of mechanical tests (set I): 10 samples x 2 configurations x 3 directions x 2 tests per load case (* a third test per load case was done on one sample for re-fixation), collecting: apparent stiffness and surface strain data, evaluating: re-fixation and re-adjustment, 4. Samples stored at −23∘C for four weeks, 5. The second set of tests (set II): 10 samples x 2 configurations x 3 directions x 1 test per load case, collecting: apparent stiffness and marker data, evaluating: storage, 6. μCT scan of the full sample (5 hours per scan), 7. The third set of tests (set III): 10 samples x 2 configurations x 3 directions x 6 repeated tests per load case, collecting: apparent stiffness and marker data, evaluating: repetition, pre-loading, μCT scanning, and loading configuration and direction
