What Is the Femoral Triangle?

The femoral distance (calcar femorale) is a dense bone plate located in the inner and rear of the femoral neck and body joints in the deep trochanter. Some people described him as "the real femoral neck." Radiates outwards to the gluteal muscle tuberosity. It is a continuous spiral plate-like layer structure. It is the eccentric load of the upper end of the femur, which is equivalent to the foundation of the crane base beam. When standing upright, it bears huge pressure and gravity. The lower pole is fused with the posterior medial bone cortex of the femoral body below the trochanter, and vertically upwards along the anterolateral side of the trochanter.

The femoral distance is attached to the medial bone cortex of the femoral neck and trunk junction, and extends to the medullary cavity. It is located at the midpoint of the intertrochanter line and the inner side of the lower edge of the trochanter. It is fused with the cortex of bone. section.

The femoral distance is a dense bone plate located at the inner and rear of the femoral neck and body joints in the deep trochanter. It is an extension of the posteromedial cortex of the femoral body into the cancellous body. Some people described him as "the real femoral neck." Radiates outwards to the gluteal muscle tuberosity. It is a continuous spiral lamellar structure, which is the eccentric loading point of the upper end of the femur, which is equivalent to the foundation of a crane base beam. When standing upright, it is subjected to huge gravitational pull ^[1] . The lower pole is fused with the posterior medial bone cortex of the femoral body below the trochanter, vertically upward along the anterolateral side of the trochanter, and the upper pole is fused with the posterior cortex of the femoral neck.

Femoral distance is an important part of the internal structure of the upper femur.It is located near the starting point of the trochanter.It is closely related to the weight-bearing function, stress conduction, stress distribution and fracture line distribution of the upper femur. Occupies a major position in body replacement. From the perspective of biomechanics, the femoral distance and the compressive trabeculae of the femoral neck inferior cortical bear the compressive stress and bending moment caused by the eccentric load on the femoral head.
