The invention is directed to a reamer (10) for shaping a bone socket (50) such as an acetabular cavity. The reamer (10) comprises cutting means for removing material from the socket during rotation of the cutting head. The cutting means comprises a number of relatively long main cutting edges, each of which extends in a direction from a base to a top of the reamers, and a number, higher than said number of main cutting edges, of relatively short peripheral cutting edges, which are located at the base and distribued at angulary spaced intervals about a rotational axis. The invention also provides a method for implanting a prosthesis component in a bone socket (50). During the shaping the bone socket, a top portion of a reamer (10) is completely received in the bone socket (50) to such an extent, that a cylindrical entrance portion (52) is formed in the socket. The invention also provides a kit including a reamer and a prosthesis. <Fig. 8> |
