ABSTRACT

 Background: Preoperative assessment by calculating the morphological cortical Index (MCI), canal-calcar ratio (CCR), canal flare index (CFI) and canal bone ratio (CBR) will facilitate appropriate surgical planning for total hip arthroplasty. Since no data on indices and ratios of proximal femur in Punjab is available the study was planned to record the same from radiographs of normal adult population.

Study design: Cross-sectional population study

Methods: MCI, CCR, CFI and CBR were calculated from measurements on anteroposterior radiographs of the proximal femur from 116 male and 96 female subjects with a mean age of 46 years.

Results: Morphologic cortical index, canal calcar ratio and canal flare index did not have any statistically significant difference between the two sexes. Canal bone ratio showed a highly significant difference when the male and female group were compared (p = 0.0042).

Conclusion: The study has provided baseline data on morphologic cortical index, canal calcar ratio, canal flare index and canal bone ratio of proximal femur in Punjab which may be helpful in surgical planning for total hip arthroplasty and further research in the area.
