  • Publication number: 20100145342
    Abstract: A disposable acetabular reamer having a cutter blade (16) molded into the surface of a support (11). The cutter blade is formed of a single flat sheet of metallic material having a series of teeth (24) formed thereon which protrude above the surface of the support such that when the acetabular reamer is rotated, the teeth contact and reduce the surface of a boney socket. The invention includes a novel method of forming the reamer which includes shaping the cutter blade once teeth are formed therein and integrating the cutter blade into the support coincident with the shaping process. The assembled unit is so economical that it may be discarded after use.
