[Radiologic correlation between the cortical-shaft index and bone mineral density in the diagnosis of osteoporosis].
OBJECTIVE
To know if radiological relationship exists among the index corticodiaphyseal of Lizaur Utrilla (ICD) and the corticofemoral diaphyseal of Gómez García (ICDF) with the density bony (DMO) mineral column power station and hip for the diagnosis of osteoporosis; with the purpose of optimizing the simple X-ray of hip well during the valuation of the bony quality.


METHODS
One carries out a study of field, traverse, comparative, descriptive and observational, where you study a representative sample of 90 feminine patients divides in three equal groups: group 1:30 healthy (control) patients from 20 to 40 years of age; group 2: patient postmenopausal and group 3:30 patients with the diagnose of hip fracture; same that were subjected to studies of simple X-ray of hip including the femur proximal as well as central DMO, stops later to obtain those mentioned indexes before mentioned.


RESULTS
For effects of this study decided to implement a new index on the base of the smallest trocanter, to which is assigned the name of index corticometaphyseal (ICM); hurtling the following results: the quantity of the bony mineral is bigger in the column (mediates: 0.973 +/- 0.168 g/cm2) that in the hip (mediates: 0.852 +/- 0.164 g/cm2); significant (p < 0.001) difference exists among each one of the indexes; the index that bigger (35 cases) correlation had with DMO was lCM with 75.5%, (68 cases) continued by ICD with 60% and (54 cases) for I finish ICDF 38%,


CONCLUSIONS
Radiological relationship of 75.5% exists between IMC and central DMO of column and hip for the diagnosis of osteoporosis.
