PROBLEM TO BE SOLVED: To provide an implant hardly causing irritations of surrounding tissue when being implanted.SOLUTION: A bone nail has a shaft with a leading end and a trailing end. The trailing end 10 includes an end surface having at least one depressed portion 21 and at least one elevated portion 22. A transition portion 23 between one of the depressed portions and the adjacent elevated portion is smoothed. The end surface 20 is formed so as to transmit translational force as well as rotational force from a medical device to the shaft of the bone nail when the medical device is coupled at the end surface to the trailing end of the bone nail. |
