A COMPARATIVE STUDY OF NECK SHAFT ANGLE OF FEMUR IN CENTRAL INDIAN POPULATION

Abstract

Background: In the fields of forensics, anthropology, orthopaedics, and human kinematics, the thigh bone femur is widely studied. The clinical significance of the femoral neck shaft angle lies in the diagnosis, treatment and monitoring of femoral neck fractures, trochanteric fractures, slipped upper femoral epiphysis, and hip developmental dysplasia. 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 150 (75 right and 75 left) dry femur were used for measuring the neck shaft angle. Unpaired t-test was used to compare right and left femora. Results: The mean value of neck shaft angle was 126.04±5.05°. It ranges between 1130 to 1360. The mean value of right side was 125.92±4.9° and left side was measured 127.43±5.2°. There was no significant correlation between right and left neck shaft angle. Conclusion: The mean left femoral neck shaft angle was higher than the right femoral shaft in the present analysis, but the values were not statistically important. The angle of the neck shaft was lower than most studies in the Western population, but it was similar to most other studies in India. In the Indian population, geographical variations in the angle of the neck shaft also occur. In the field of orthopaedic surgery and anthropometry, this research will be of benefit.
