Purpose: This study aimed to evaluate anatomical character of proximal femoral canal of Korean.
Materials and Methods: Total 180 radiographs of proximal femur of healthy subjects without previous trauma or other pathology in hip joint were reviewed to measure the parameters and analyze the correlation.
Results: Femoral head offset of Korean was small and femoral neck-shaft angle was large. Weakest correlations were observed between pairs of periosteal and endosteal parameters. Stronger correlations were observed between parameters describing the width of the canal in the vicinity of the lesser trochanter. The proximal canal was more flared at proximal to lesser trochanter. The shape of the endosteal canal of isthmus is nearly circular in Korean. Canal flare index was distributed from 2.4 to 5.8 with an average of 4.02±0.65. The stovepipe, the normal, and the champagne flute type included 5.6%, 79.4%, 15.0%, respectively. The canal flare index decreased gradually according to age.
Conclusion: Geometry of femur from Korean showed some characteristic features. The canal flare index of Korean femur and its distribution of type are not differ from those of American femur in the similar age group.
