Abstract
A novel coated prosthesis that can be tailored to avoid the problem of bone resorption caused by stress shielding. The permanent, load-bearing skeletal replacement prosthesis is coated or covered with a bioabsorbable polymer at selected sites on its surface so that bone affixation is preferentially delayed at these covered sites and bone adjacent to uncoated areas are not stress shielded. Thus, resorption is avoided. When the bioabsorbable polymer is gradually absorbed away, bone affixation takes place on the exposed surfaces, as needed.
