This paper deals with evaluation of mechanical properties of human trabeculae in the interconnection
area. Local changes in the trabecular connections were evaluated using both quasi-static
nanoindenation and modulus mapping technique. Connecting point of two trabeculae was revealed
by precise grinding and polishing. A rectangular region in the interconnection was selected and inspected
by modulus mapping procedure. Moreover several quasi-static indentation measurements using
cube-corner indenter were performed along distinct lamellae. The obtained elastic properties were
then compared with the values of the rod-like trabeculae. The comparison does not indicate significant
differences in elastic properties between the trabecular rods and interconnections.
