Abstract:
1. A unitary acetabular cup prosthesis for use in a deficient acetabulum of a hip bone of a patient, the prosthesis comprising: a cup portion comprising a generally dome-shaped wall having an axis and an upper rim, an inner bearing surface of said wall configured to pivotally engage a femoral head of a hip prosthesis, a pair of adjacent screw retaining members for use in attaching the prosthesis to the patient's hip bone, each said screw retaining member extending from an outer surface of said dome substantially along said rim, each said screw retaining member integrally formed with said cup portion such that said screw retaining member is fixedly inclined relative to said rim and is fixedly offset relative to said rim, said screw retaining members oriented in a cooperative relationship with one another to facilitate implantation of the prosthesis in one side of the hip of the patient, and each said screw retaining member having a threaded hole therethrough, each said threaded hole fixedly inclined relative to said rim such that an axis of said threaded hole converges toward said axis of said cup portion in one dimension and such that said axis of said threaded hole is oblique to said axis of said cup portion in a second dimension.
