Background and Aims:Fractures involving the neck and trochanter of the femur are very common. Internal fixation with implants for these fractures is important for rehabilitation and early mobilization of the patients. Depending upon the dimensions of the upper end of the femur, the implants are designed. Currently most of the orthopaedic surgeons need notifications in the dimensions of the implants that suit the Indian standards.This study is designed to find out whether there is any significant difference between right and left femur for the purpose of modelling orthopaedic implants as the femoral fractures are very important health burden in India. Materials and methods:This study done with 90 dry adult femur bones of both sides from the department of anatomy at Sree Mookambika Institute of Medical Sciences, Kulasekharam, Tamil Nadu. By using a coloured thread, axis of the neck of femur was determined. The thread divides the anterior surface of the neck into two equal halves. In the mid sagittal plane over the anterior surface, the axis of the shaft was marked using same thread.Then the angle between the neck and shaft is measured using the goniometer. The measurement was subjected to statistical analysis to evaluate the significance. Result: We observed that the mean neck shaft angle of the left side was 126.15±4.22 degrees and the mean value of the right side was 127.20±2.43 degrees.
