ABSTRACT
Background: Osteoporosis progresses with advancing age. Estimation of bone mineral
density (BMD) using dual energy X-ray absorptiometry (DXA) is valuable in
predicting fracture risk in the elderly. DXA machines however may not always be
available in under-resourced developing countries.
Aim: To find
values of CTI and CFI in normal adult young and old, male and female population
of Southern Punjab.
Study design: Cross-sectional population study
Methods:
Measurements were recorded from 107 anteroposterior radiographs of proximal
femur of normal adult male and female subjects divided in two groups: Young: 22
male and 26 females with mean age 28±3.4 and Old: 31 male and 28 females with
mean age 61+5.2.
Results:
Statistical comparison between male and female subjects for CTI was not
significant in the Y and O groups. Similar comparison for CFI while not
significant in the Y-group was highly significant in the O-group. In overall
comparison of Y and O groups the difference was very highly significant for CTI
and CFI; both showing higher values in the Y-group.
Conclusion; CTI and CFI measured from radiographs of proximal femur are reliable
parameters and can be recommended for preliminary assessment of bone mineral
density in developing countries.
Keywords: Proximal
femur, morphometry, cortical thickness index (CTI), canal flare index (CFI),
bone mineral density
