“…The decline of bone mass with increasing age has been established for a long time . Age influences bone health with direct and indirect effects on bone mass, and mechanisms of age‐related bone loss include remodeling imbalances, the decrease in the intestinal production of 1,25‐(OH) 2 D 3 , secondary hyperparathyroidism, and the accumulation of damage in osseous tissue and reduction of viable osteocytes .…”

Age at death estimation in adult skeletons is hampered, among others, by the unremarkable correlation of bone estimators with chronological age, implementation of inappropriate statistical techniques, observer error, and skeletal incompleteness or destruction. Therefore, it is beneficial to consider alternative methods to assess age at death in adult skeletons. The decrease in bone mineral density with age was explored to generate a method to assess age at death in human remains. A connectionist computational approach, artificial neural networks, was employed to model femur densitometry data gathered in 100 female individuals from the Coimbra Identified Skeletal Collection. Bone mineral density declines consistently with age and the method performs appropriately, with mean absolute differences between known and predicted age ranging from 9.19 to 13.49 years. The proposed method-DXAGE-was implemented online to streamline age estimation. This preliminary study highlights the value of densitometry to assess age at death in human remains.

“…The Singh index may be useful in the measurement of the bone mass in the proximal femur, as a good correlation has been reported between the bone ash density and the Singh grade in the excised femoral heads [15]. A good separation of the fracture patients from the controls have been done by using the Singh index [16,17]. The correlation between the Singh index and the bone mineral densitometry in the femoral neck in the screening and the grading of osteoporosis and in predicting femoral neck fractures has been reported to be from moderate to nil [18][19][20].…”

Objective: Anatomically, the upper end of the femur is a common site for osteoporosis. Therefore, The trabecular pattern in the upper end of femur is analyzed on the basis of the presence or absence, the relative number and density of the trabeculae, trabecular group and also by the grading of trabeculae. The present study was undertaken to identify the trabecular pattern in the upper end of the femur radiographically in postmenopausal women and to establish that the changes in the trabecular pattern can be used for the diagnosis and the grading of osteoporosis. While osteoporosis is observed in both elderly men and women, its prevalence is much higher in post-menopausal women. The validated data from this study will be of use to all the clinicians to recognize the trabecular patterns and it will possibly help them in detecting osteoporosis and in limiting its progress in its early stages.Method: Two hundred frontal projection pelvis radiographs of women who were between 18-100 years of age were studied during 2006-2007. In this study, an attempt was made to test the presence, pattern and the grading of the trabecular pattern in pre and post-menopausal females and to find out the influence of the post menopausal age on the trabecular patterns. All the readings were tabulated and subjected to analysis.

“…Film criteria for osteoporosis have included analysis of the trabecular pattern [4,17], loss of horizontal trabeculae with prominence of vertical trabeculae [18], reduction in the thickness of the cortex of the vertebral body (and femoral cortex) [14], and increased prominence of vertebral end-plates [18]. An increase in biconcavity of the vertebral bodies has also been used as an indicator of osteoporosis [1].…”

Osteoporosis: diagnosis by plain chest film versus dual photon bone densitometry

1990

Readers of chest radiographs often comment on the presence of osteoporosis. We have hypothesized that diagnoses of osteoporosis from chest films are not reliable even when made by experienced radiologists. To test this hypothesis, we had nine radiologists estimate the degree of bone density seen on 45 lateral chest films. We compared their estimates of bone density to the results of dual photon bone densitometry of the lumbar spine. We found that there was little ability to accurately diagnose osteoporosis by chest film since the group of nine readers achieved accuracies ranging from 0.59 to 0.64. Therefore, we feel it is unjustified to comment upon the presence or absence of osteoporosis on the basis of chest films.
