ALVAREZ CAMBRAS, RODRIGO et al. Bone densitometry and risk prediction of the hip fracture. Rev Cubana Ortop Traumatol [online]. 1996, vol.10, n.2, pp. 119-124. ISSN 1561-3100.

This paper is the result of a multicenter investigation that served as a clinical assay for the validation of a bone densitometer (Degos 7032). The study was based on the comparison of two groups of persons: one of the 50 apparently sound volonteers and the other of 39 patients with hip fracture. To compare both groups it was used for the evaluation the F Fischer's test if the difference between the bone density variances (CMO-width) was significant in the distal extreme of the ratio by using the method of simple photon absorptiometry. Then, another comparison was made by the t of Student test (for unmatched values). The difference between the means was significant. It was concluded that the bone density magnitude is an index that allow to differentiate both groups and that it may be used to monitor the hip fracture risk and to anticipate to the trauma caused by fracture.
