Introduction: For an exact subsequent determination of lack of substance in the femoral head in multiple diseases, this paper wishes to measure the "whole„, respectively the femoral head, so that later on this would represent the basis of calculus of possible bone deterioration. Material and method: The lot that we studied was constituted of prepared bones: 19 femurs, out of which 11 were from the right side and 8 from the left side. The measurements were done by two methods. The first was the direct method of physical measurement of the femoral head and the second was the measurement with the aid of a software on the CT scans that we've performed. Results and discussions: One of the most important problems that arises during direct measurements, obvious from the very beginning, was the degree of deterioration of the prepared bones due to more or less careful manipulation over time. The CT scan technique obtained successive images at 1 mm interval. The subsequent use of the software that helps establish the volume depends on some sources of error. The two methods of volumetric assessment overlap to a positively variable degree that can still be subjected to corrections. Conclusions: The volumetric assessment of the femoral head is not yet a routine measurement, recognized and in 100% correspondence to the physical volumetric measurements. We consider that the improvement of the computerized algorithm would lead to more precise results. [ABSTRACT FROM AUTHOR]
