Abstract

Background: Knowledge of various dimensions of the femoral head in both the sexes is of great help in manufacture of the prosthesis of femoral head which may be used by the orthopaedic surgeons in femoral head replacement surgery. Present study was aimed to study, gender and age based morphometric study of hip joint in plain radiographs of adult Indian population. Material and Methods: Present study was single-center, observational study, conducted in 264 AP plain radiographs of normal hip joints (147 males and 117 females). All linear measurements including acetabular depth, acetabular diameter, femoral head diameter, femoral neck length, femoral neck width, joint space width were measured using Dicom viewer. Results: The mean femoral head diameter noted on right side in males was 52.36 ± 5.34 mm & in females it was 46.68 ± 3.31 mm. The difference in mean femoral head diameter was found to be statistically significant (P<0.05) when the comparison was made between left side hip joint radiographs of males and females Higher mean value for FHD was recorded in men when the 2 genders were compared irrespective of side. Higher values of femoral neck width (FNW) were observed in males than in females, and the value was more on right side. Higher mean femoral neck width value was recorded on right side when compared to left side. The difference in mean femoral neck width was found to be statistically significant (P <0.01) when the left side hip joints were considered in the 2 genders. Higher mean value of femoral neck length (FNL) was observed in males than in females and the values were higher on right side than on the left.
