<p><P>PROBLEM TO BE SOLVED: To improve an initial fixing property and facilitate processes of inserting to a thigh bone and pulling out of the thigh bone. <P>SOLUTION: A pair of front and rear surfaces (12, 13) has a pair of front and rear surfaces (16, 17) mounted on the proximal side and a pair of front and rear surfaces (18, 19) mounted on the distal side under a condition of implantation in a thigh bone. The pair of front and rear surfaces (16, 17) at the proximal side and the pair of front and rear surfaces (18, 19) at the distal side are formed to be different in inclination in the axial direction. A pair of border lines (20, 21) partitions each surface of the pair of front and rear surfaces (16, 17) at the proximal side and the pair of front and rear surfaces (18, 19) at the distal side and elongates from the inside to the outside, and includes an elongating part to the direction inclined in a vertical direction to the axial direction. <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
