A Morphometric Study of Upper End of Femur and Its Implications in Hemiarthroplasty

Abstract

Hemiarthroplasty of hip is very common now-a-days in fracture neck of femur. So there is always need of population specific data for making best fit prosthesis to reduce complications following the procedure.Objectives: To measure Femoral Head Diameter, Femoral Neck Length, Femoral Neck Diameter, Femoral Neck Thickness and Cervico-Diaphyseal Angle. To find the correlation between each parameter.Materials and method: 100 dry femur, required for the study, were collected from the Department of Anatomy, Mysore Medical College, Mysore. Measurements were obtained using a digital vernier calliper, a ruler and a protractor. Results: Mean value of Femoral Head Diameter was similar to other Indian studies. Mean value of Cervico-Diaphyseal Angle varied as that of western studies. The values of Femoral Head Diameter show high correlation with the values of Femoral Neck Diameter, Length and Thickness. Conclusion:The regional variations noted in this study will help designing prosthesis of appropriate head, neck and stem size, thus reducing the failure rates in hemiarthroplasty.
