A reamer assembly for preparing the articulating surface of a bone for implantation of joint prosthesis component comprises a reamer guide which can be implanted within the bone to define a reaming axis, and a reamer shell which comprises a sleeve portion at its proximal end. The shell is a sliding fit on the reamer guide and has an array of cutting teeth which are radially spaced from the sleeve portion, for cutting the bone around the reamer guide to a desired shape. The reamer shell includes (i) a distal edge which provides an array of cutting teeth, and (ii) a shell wall which extends proximally from the distal edge and has an array of cutting teeth formed in it, directed inwardly to cut bone tissue located within the shell. |
