Femoral lesser trochanter securing device for firmly securing the lesser trochanter and the surrounds and stably strengthening the same so as to allow artificial hip replacement surgery

An artificial joint for use in hip joint replacement, comprising:

• an artificial femoral stem adapted to be inserted, when in use, into a femoral medullary canal;
• a basket portion adapted to cover a lesser trochanter when in use;
• and
• a buttress plating portion joined to a lower edge of the basket portion and is adapted to extend, when in use, toward a femoral shaft such that the buttress plating portion is secured and joined to the femoral shaft, the basket portion comprising a protrusion extending outward so as to be in conformity with the lesser trochanter when in use,
• wherein the protrusion has a truncated conical shape having first to third planes adapted to cover the lesser trochanter when in use,
• the first plane is disposed in a direction of the femoral shaft with respect to an intertrochanteric line,
• the second plane is disposed in a direction of the femoral shaft to face the first plane, and
• the third plane is disposed toward a femoral neck.
