Abstract
A holder for an acetabular reamer of the type including a generally hemispherical shell having a circular edge and cross arms connected adjacent to the edge and which converge at the center of the edge. The holder includes a base having a datums and at least three pedestals extending up from the base at locations spaced radially from, and distributed about, the datums. Each pedestal has side walls and an upper wall extending between the side walls and facing away from the base. The upper wall is curved so that together the upper walls of the pedestals define an imaginary surface having substantially spherical curvature, so that the pedestals help to retain a reamer whose shell is congruent to the collective upper walls and whose edge is substantially parallel to the base.

A holder for an acetabular reamer of the type including a generally hemispherical shell having a circular edge and cross arms connected adjacent to said edge and which converge at the center of said edge, said holder comprising a base having a datums, and at least three pedestals extending up from said base at locations spaced radially from, and distributed about, said datums, each said pedestal having side walls and an upper wall extending between said side walls and facing away from the base, said upper wall being curved so that, together, the upper walls of the pedestals define an imaginary surface having substantially spherical curvature, said pedestals helping to retain a reamer whose shell is more or less congruent to said collective upper walls and whose edge is substantially parallel to said base.
