PCT No. PCT/AU86/00321 Sec. 371 Date Aug. 20, 1987 Sec. 102(e) Date Aug. 20, 1987 PCT Filed Oct. 28, 1986 PCT Pub. No. WO87/02571 PCT Pub. Date May 7, 1987.A device, and method of producing and using same, for use in removing the prosthetic cement from a bone in which an artificial joint (such as hip joint) is to be replaced. The device cuts the prosthetic cement in a longitudinal plane of the prosthetic cavity to the complete depth or the cement but without substantially cutting into the bone. The device includes a reciprocating saw head (8) which is advanced longitudinally of the cavity and maintained within the preselected longitudinal plane of the cavity by a guide (1) while it cuts through the cement (10). The saw head (8) is transversly biased towards the cement so that it cuts only to a depth defined by the profile of a template (6). The profile of the template (6) is obtained from X-ray information obtained before commencement of the operation. |
