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
