Roentgenographic Study on Shape and Size of the Femoral Head of Normal Korean Adults / 대한정형외과학회잡지

ABSTRACT

In order to provide the basic data about the hip joint arthroplasty, we measured the femoral head diameter, offset and position in normal 150 males and 150 females using a standardized roentgenographic technique that provided views perpendicular to the plane of the femoral neck in which the focus centered on the lesser trochanter of the femur. We obtained 11.4% of magnification rate by comparing the real size of femoral marker with radiologic size. The result of this study are as following The mean femoral head diameter was 46.4 ±4.1mm in male and 45.1±3.8mm in female. The mean femoral head offset was 39.2±4.8mm in male and 37.8±4.6mm in female. The mean femoral head position was 48.9±3.2mm in male and 47.6±3.6mm in female.
