From: Which experimental procedures influence the apparent proximal femoral stiffness? A parametric study
The proximal portion of samples was potted at (a) shaft, and (b) head and trochanter locations using Polyurethane (PU) casting resin and a custom-made setup. (c) The posterior femoral neck area was sprayed with an airbrush to create a speckle pattern (trial tests). Three marker clusters containing four markers each were placed on the femoral head, trochanter, and shaft of the prepared samples
