Introduction: Pilasteric index of femur is a measure of flatness of middle of the shaft. It is obtained by dividing midshaft AP diameter of femoral shaft with midshaft transverse diameter of femoral shaft. Aims and objectives: Present study was aimed to ascertain values of pilasteric index in Gujarat region and to evaluate its possible efficacy as a racial characteristic. Material and Methods: Study sample consisted of 242 dry, human, adult femora [176male (87 right, 89 left) and 66 female (32 right, 34 left)] from skeletal collections of Anatomy departments of two different Medical Colleges of Gujarat. Midshaft AP diameter & midshaft transverse diameter of femur were measured and pilasteric index was calculated using the formula, Pilasteric index= (Mid Shaft AP diameter *100)/ Mid Shaft transverse diameter. Observations and Results: Mean values of pilasteric index of normal human adult femora from Gujarat region, in male were 102 (Right) & 100.20 (Left) and for female were 93.82 (Right) & 102.37 (Left). Mean pilasteric index of male in present study was lower than the Australia and Andaman and was similar to English, Male thai, India, Ceylonese, Japan and China. Mean pilasteric index of left side female femora in present study was lower than the Australia and Andaman and was similar to English, India, Ceylonese, Japan and China; while for right side female femora it was lower than the Australia, Andaman, English, India, Ceylonese, Japan and China.
