摘要：A prosthesis for implanting into a bone having a cavity is disclosed. Theprosthesis comprises a body and a stem. A first coating including a bone ingrowthpromoting material that promotes ingrowth of bone onto the stem and a bioabsorbablematerial that delays the ingrowth of bone onto the stem is disposed on a proximal

portion of the stem outer surface. A second coating including the bone ingrowth

promoting material and the bioabsorbable material is disposed on a distal portion of thestem outer surface. The ratio of bone ingrowth promoting material to bioabsorbablematerial in the first coating is greater than the ratio of bone ingrowth promoting materialto bioabsorbable material in the second coating whereby the affixation of the bone tothe proximal zone of the stem is faster and stronger over time than the affixation of thebone to the distal zone of the stem.
