Abstract
An acetabular reamer of the type used in total hip arthroplasty (THA) to prepare a patient's acetabulum for implantation of a hip prosthesis is described. The acetabular reamer consists of a substantially hemispherical cup having a plurality of cutter-hole combinations aligned along one or more loxodromes on the surface of the hemispherical cup. The reamer, complete with integral back plate for connecting the reamer to a driver, is produced to net shape using a molding and sinterwelding technique.
