On this work, the evaluation of the proximal extremity of 183 dry femurs, taken from corpses of Brazilian adults, collected, randomly, in the Anatomic Department of the State University of Rio de Janeiro has been analyzed; either sex status or chronological age of the sample were not considered on this work. Morphometric measurements were taken, and bony densiometry (DEXA) done on 18 of then. The morphometric measurements were: length of the femoral neck (CCF); width of the femoral neck (LCF); length of femoral axis (CEF); neck-shaft angle (ACD). The measurements were then submitted to arithmetic average (X), standard deviation (SD) and medium (Me), the Student t and Non-Parametric Mann Whitney tests, as well as the linear regression and correlation analysis between the variables that presented in association with CEF. A correlation analysis morphometric measurements and the mineral bone density (DMO) were also done, as well as the density itself. The average values found for the right and left sides were: CF = 436.9 ± 26.3 mm and 441.7 ± 27.7 mm; CCF = 24.9 ± 4.5 mm and 24.3 ± 4.2 mm; LCF = 26.7 ± 3,1 mm and 26.3 ± 3.3 mm; LDF = 29.8 ± 2.9 mm and 30.7 ± 2.6 mm; DCF = 43.5 ± 3.3 mm and 43.9 ± 3.7 mm; CEF = 92.1 ± 6.9 mm and 92.0 ± 7.1 mm; AI = 111.2° ± 5.9 and 114.2° ± 5.5; AT= 16 ° and 18°. The results have shown no significant differences regarding the femur side (right and feft) , but those have been shown when CEF versus DCF and CEF versus LDF have been compared. The morphometry has also been correlated to the densiometry and no significance has been found. A positive significance has been found in the densiometry itself. The literature review has mentioned differences in race, bone mass and proximal extremity architecture and has postulated their relevance regarding the potential fracture risk. Based on this work, the authors have concluded that such a study could be used as a parameter for the Brazilians femurs, and it could be related to the clinical practice.
