Abstract

Background and objectives: The proximal end of femur has been the subject of much attention for Orthopaedic surgeons, as operations on it are one of the commonest among orthopaedic surgical procedures. Fractures of proximal femur are quite common. Internal fixation of these fractures with implants is required for early mobilization of patients. The knowledge of morphology of proximal end of femur is essential for designing of hip replacement implants and for planning before hip arthroplasty.

Methodology: The study was conducted on 280 adult human femora (136 right and 144 left). Sliding calliper and measuring tape were used for measurement of vertical and transverse diameter of head of femur, head circumference, vertical and transverse diameter of neck of femur and length of neck of femur. Results were analyzed statistically.

Results: Mean vertical and transverse diameters of head were found to be 40.53±3.51mm and 40.44±3.47mm respectively. Mean circumference of head was 126.33±12.61mm. Mean vertical and transverse diameter of neck were 27.82±2.82mm and 23.20±2.83mm respectively, mean length of neck of femur was 29.35±4.32mm.

Conclusion: Mean value of all parameters of femur in the present study showed significant differences with those obtained in other populations (p<0.01), proving racial and regional variation in femoral geometry. The present study has established valuable parameters which will be of help to forensic experts, anthropologists, orthopaedicians and bio-mechanical engineers in their respective specialities. It will be a guide for future implants design, to provide better fitting implants for the Maharashtrian population.
