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