Transverse Diameters of Head and Neck of Femur in Central India Population

Abstract

Introduction: The proximal end of Femur consists of the head, the anatomical neck which joins head to the trochanters, trochanters which serve as insertion sites for muscles, and the surgical neck that attaches the proximal epiphysis with the diaphysis. It is imperative for Anatomists, Radiologists, Forensic experts and Orthopaedicians alike to stay abreast about the morphometric characteristics of proximal Femur. Objectives: This study was planned to measure transverse diameters of head and neck of Femurs in central India population. Materials and Methods: This study was performed on 100 dried, intact, nonpathological Femurs of both gender over a period of 2 years. Vernier Calipers, Osteometric Board, Goniometer, and Fiberglass Tape were used for measurement of transverse diameters of head and neck of Femurs. Results: Transverse Diameter of Head (TDH) was found to be 4.3 ± 0.3 cm on both sides in males, and 4.3 ± 0.5 cm (Right side) and 4.3 ± 0.2 cm (Left Side) in females. In males, Transverse Diameter of Neck (TDN) was 2.6 ± 0.3 cm (Right side) and 2.5 ± 0.3 cm (Left Side). TDH and TDN were found to be higher in female Femurs. There was no statistically significant difference in TDH and TDN between Right and Left side. Conclusion: Femur being most important bone of thigh, health care practitioners should be well aware of head & neck morphometry of Femur and its variations.
