摘要:
The femoral stem prosthesis includes a prosthesis body having a neck, stem, and porous coating receiving area. A portion of a transition between the porous coating receiving area and the stem is defined by a recess where the porous coating receiving area inwardly extends by a depth relative to the stem while the porous coating receiving area is approximately flush with the stem about a remainder of the transition between the porous coating receiving area and the stem. A porous coating overlying the porous coating receiving area has a thickness approximately equal to the depth of the recess to define a smooth transition between the porous coating and the stem along the portion of the transition by the at least one recess and a collar outwardly extending relative to the stem by approximately the thickness along the remainder of the transition between the porous coating receiving area and the stem.
