In this article we introduce a stereological parameter for quantitation of new bone structure -the star volume- which does give an absolute and a reasonably precise estimate of the size of the trabeculae and of the size of the marrow space in three-dimensional terms (mm3 or mm3), applied to evaluate the new bone formation derived from bone substitutes.
