The calcar femorale can be classfiedmorphologically into three types. On the average, the calcar femorale extends proximallyfrom 1.46±0.52 cm above the lesser trochanter to distally 0.42±0.60 cm below the distalmargin of the lesser trochanter. In 80% of the femurs, the widest and thickest part ofthe calcar is near the proximal margin of the lesser trochanter. The values of 5parameters of human calcar are provided. The development of calcar femorale amongChinese is fully accomplished at the age of 7-11. Bovine and monkey also has calcar butthe direction of its transverse axis is statistically different from that of the humans.展开更多
