Abstract:
Anthropological studies of the proximal femur in a given race is a prerequisite step in designing femoral component of the total hip arthroplasty. As these studies and subsequent data are lacking for Korean hips, the author attempted an anthropological measurement of the Korean proximal femur. The results of this study are as following; l. In the orthoscanographic study for 187 subjects, mean of the maximum femoral length was 43.73±2.13cm for male, 40.53±2.03cm for female, The proportion of femoral length to the body height was found to have a constant ratio −26.10% for male, 25.91% for female. 2. In Anthropological measurement of Korean femur for 58 subjects, mean angle of the femoral anteversion was 19.85±6.86 and the neckshaft angle was 129.6±3.09. 3. In the study of the anterior curvature of femur, position index was 51.95±14.5% for male, 52.61±9.25% for female and index of bowing was 2.58±1.01% for male, 3.01±1.25% for female. In comparision with other races the Korean femur was found to have relatively straight curvature and the apex of the maximum curvature was located more distally. 4. External circumferential diameter of the femur-measured at 15cm below the lesser trochanter-showed 8.79±0.59cm for male and 8.42±0.53cm for female. The sexual difference at this level was statistically significant. (P <0.05). 5. In selected cadaeveric femurs, the minimum transverse diameter of internal mold was 1.26±0.30cm and was located at 12.5cm below the lesser trochanter to 20cm can be estimated by the following equation. Y=2.234−0.191X+0.0078X² for male, Y=2.395−0.173X+0.007X² for female.
