Abstract
It was the principal objective of this study to evaluate the use of a preformed block of hydroxyapatite in an animal model of a porous-coated implant with an interface gap. It is shown that extensive ingrowth into the porous hydroxyapatite, regardless of pore size, was observed. The lack of ingrowth into the porous CoCrMo plug as demonstrated histologically was confirmed by the radiologic and biomechanical data. It is possible that the HA-metal interface presents another barrier for the bone to cross. Additionally, the HA provided may be so compact and interwoven with pores that it takes longer for the bone to bridge the HA sleeve.
