Correlation between neck shaft angle of femur with age and anthropometry: A radiographic study

Introduction: Neck shaft angle of femur (NSA) and body mass index (BMI) are important determinants of fracture neck femur which is considered to be a health burden of our society. Methods: In this study fifty people aged more than fifty years were selected consecutively after interview and examination in department of Radio diagnosis, Medical College, Kolkata. Neck shaft angle was measured on the skiagrams at the right side in twenty-five cases and at the left side for rest of the cases. Age, weight, height were recorded and BMI was calculated. Correlations between NSA and different parameters were determined after statistical analysis with Epi-info 3.5.1. Observations & Result: Moderate correlation between NSA and BMI was found in cases with right sided skiagrams whereas strong correlation of NSA with weight was obtained for left sided cases. Moderate correlation was also seen between NSA and BMI in persons with normal BMI and with height in persons with high BMI. No correlation was found with age. Moderate to strong correlation was obtained between NSA and anthropometric parameters but not with age. Conclusion: This study establishes correlation between neck shaft angle of femur and different anthropometric parameters. Moreover, any of them can be predicted if another variable is known.
