A comparative study of neck shaft angle of femur in Madhya Pradesh

Background: Prevalence of hip osteoarthritis, femoral neck fracture and other hip joint ailments are increasing  day by day. Total hip arthroplasty is a commonly performed surgery now a day. There are regional and racial variations in the stature of the population of India. So there is always need of specific data for best fit prosthesis. Objective: The present study was conducted to compare the NSA disparity between femurs on both sides and to compare the NSA with the Western and Indian population sizes of different regions. This research therefore leads to Indian data on these parameters. Materials and Methods: A total of 200 (100 right and 100 left) dried femur bones were used for measuring the neck shaft angle. For comparing the right and left femora, unpaired t-test was used. Results: The total mean value and standard deviation of neck shaft angle was 126.71°±5.12°.  It ranges between 113° to 136°. The mean value of right side was 126.04±4.93° and left side was measured 127.40±5.20°. There was no significant correlation between right and left neck shaft angle. Conclusion: The mean left femoral NSA was higher than the right femoral shaft in the present study, but the values were not statistically important
