Abstract
The use of a new, direct estimator of 3-D connectivity in arbitrary networks, the ConnEulor, based on the disector-principle is illustrated in a series of iliac crest bone necropsies. To obtain an unbiased estimate of connectivity or “trabecular number” takes about 1 hour per specimen.
A rather pronounced relation between connectivity and age was seen in females, it corresponds to a halving of trabecular number over ~50 years. No such relation was observed in males. No correlation obtained between connectivity and trabecular volume density.
