ABSTRACT:

Introduction: The femoral neck anteversion can be defined as the angle between femoral bicondylar plane and a plane passing through the centre of the neck and head of femur. Adult femoral anteversion has been documented at the range between 7-16 degrees. This angle is widely recognized as an important factor for hip stability. The present study aimed to evaluate the normal anteversion range in adult Indian femur which would be of great help in explorative orthopedic procedures and in designing of hip prosthesis.

Materials and Methods: Study conducted in 202 femurs of 94 male (48 right and 46 left) and 108 female bones (52 right and 56 left). And the angle was measured using Kingsley Olmsted Method.

Observation and Results: The mean value of anteversion angle of femur was 7.61 degrees for male and 12.71 degrees for females. Mean anteversion angle for both male and female femur was 10.37 degrees. Retroversion was observed in 10 femurs(5%) and neutral version was observed in12 femurs (5.9%).

Conclusion: Determining the anteversion angle is crucial for the diagnostic and therapeutic planning of patients with various pathologies such as hip development dysplasias, cerebral palsy, varum thigh, flat thigh, epiphysiolysis, congenital club foot, congenital dislocation of the hip and other development abnormalities. Statistical analysis revealed sexual dimorphism in anteversion in Indians being greater among females than males.

Key words: Neck of Femur, Anteversion, Retroversion, Neutral version, Total hip replacement, congenital dislocation of hip.
