ABSTRACT:
The present invention provides a prosthetic implant 510 including a stem portion 520 having a discrete, circumferential porous pad 526 mounted directly on the stem portion 520 in surrounding relation thereto. The pad 526 includes a first end 528 and a second end 529 such that when the pad 526 is mounted on the stem portion 520, the first end 528 and the second end 529 face each other and are interconnected at a seam 527 therebetween, such that the interconnection reduces the advancement of wear debris along the seam 527.
The interconnection may include at least one pair of mating interlocking tabs 600 on the pad 526. Alternatively, the improved interconnected seam 700 may be improved by the use of a metallurgical bond along the seam 727 or by the use of a filler material along the seam 727 to reduce the possibility of wear debris advancing or traveling along the seam.
