Avaliação radiográfica morfométrica e índice de singh para osteoporose da região proximal do fêmur em mulheres com 60 anos ou mais e sua relação com e sem fraturas proximais do fêmur

Abstract

The aim of the study was to analyze and relate the morphometric and Singh indexes for osteoporosis as predictive factors in the fractures of this region. Methods: The women were divided into three groups from the age of 60 to 70, from 71 to 80 and over 80 years old, with and without femoral neck fractures and femoral trochanteric fractures. The X-ray was performed in anteroposterior pattern, and the femoral neck width (CFA), femoral neck length (CCF), femoral shaft diaphysis angle (ACD), femoral shaft length (CEF) and Singh index osteoporosis always on the right side in the without fractures and on the lateral side in those with fractures. The statistical analysis was performed for the comparison of the morphometric measures and the age was used Student's t-test, between the means of the morphometric measures and the age groups and also in women without fracture and according to the type of fracture was used the test ANOVA with Post HOC of Bonferroni. In the correlation between the means of the morphometric measurements and the age, Pearson's correlation test was used. In the association between the Singh index and the occurrence of fracture, Fischer's exact test was used and in the association between the Singh index and the type the Pearson Chi-square test. The significance level was p <0.005. We had a mean age of 75.5+ - 8.8 years with an interval between 60 and 96 years, of which 50% had fractures. Results: In the morphometric measurements and the mean age we had significance with the increase in the femoral neck width (LCF) and in the increase of the cervical angle diaphysis (ACD) in the patients with fractures, while the increase in femoral neck length (CCF) was higher in the non-fractured ones. The length of the femoral axis was not significant in the association of Singh index and frequency in women with and without fractures, there was a significant difference in Singh II index in the fractured ones. Regarding the type of fracture, whether in the neck or trochanteric region, and also in relation to age, there was no significance. Conclusion: We infer that the association between morphometric measurements of the proximal femur region and the Singh index using standard basal radiography is predictive of the risk of fractures in this region in women over 60 years of age with a low financial cost, being easily accessible to the population in all services of Orthopedics and Traumatology by the Unified Health System (SUS).
