Morphometry of Proximal Femur in Indian Population.

INTRODUCTION

Total hip arthroplasty is a commonly performed surgery now-a-day. There are regional and racial variations in the stature of the population worldwide. So there is always need of population specific data for making best fit prosthesis.

AIM

The present study was done to measure the parameters of proximal femur and to analyse their correlation by using standard statistical analysis.

MATERIALS AND METHODS

Ninety one dry bones (44 left and 47 right) were used. Femur Head Diameter (FHD), Femur Neck Length (FNL), Femur Neck Diameter (FND), Femur Neck Thickness (FNT), Cervicodiaphyseal Angle (CDA) was directly measured with the help of anthropometric instruments. Femur Head Offset (FHO) and Vertical Offset (VO) were measured in the anteroposterior digital photographs.

RESULTS

Normally distributed variables were compared using Student's t-test (Unpaired data) to analyse significant effect. There was a significant difference between right and left side of FND and CDA. Pearson correlation coefficient was used to analyse the relationship among variables. FHO had high correlation with the VO (0.687, p<0.001).

CONCLUSION

These parameters can be used for designing the prosthesis and plates for hip joint reconstructive surgeries suitable for Indian population.
