Unitary acetabular cup prosthesis with extension for deficient acetabulum

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 a substantially planar upper rim, an inner bearing surface of said wall configured to pivotally engage a femoral head of a hip prosthesis,
• a flange member integrally formed with said cup portion, said flange member comprising
• a base portion extending upward along a portion of said upper rim,
• a generally planar screw retaining portion, said screw retaining portion inclined from said base portion such that at least a lateral portion of a lower surface of said screw retaining portion is positioned below said upper rim while an upper surface of said screw retaining portion is positioned above said upper rim,
• said screw retaining portion having a first threaded hole, a second threaded hole and a neutral threaded hole formed therethrough, said neutral threaded hole positioned between said first and said second threaded holes,
• said first threaded hole fixedly inclined relative to said upper rim such that an axis of said first threaded hole inclines toward said axis of said cup portion in a first dimension viewed generally along a width-wise side of said flange member, and such that said axis of said first threaded hole is offset laterally from said axis of said cup portion in a second dimension viewed generally along a length-wise side of said flange member,
• said second threaded hole fixedly inclined relative to said upper rim such that an axis of said second threaded hole inclines toward said axis of said cup portion in said first dimension, and such that said axis of said second threaded hole is offset laterally from said axis of said cup portion and divergently from said axis of said first threaded hole in said second dimension,
• said neutral hole fixedly inclined relative to said upper rim such that an axis of said neutral threaded hole inclines toward said axis of said cup portion in said first dimension and such that said axis of said neutral threaded hole is substantially parallel to said axis of said cup portion in said second dimension, and
• said first, second and neutral threaded holes spaced sufficiently adjacent one another to thereby allow the prosthesis to be used in either a left or a right hip of a patient.
