An implantable prosthesis system including a selectively applied bone
growth promoting agent is disclosed. The types of prostheses which may
include a selectively applied bone growth promoting agent include rods,
fracture plates, screws, as well as other types of prostheses.
Additionally, the structural composition of many types of prostheses may
be modified to help induce bone ingrowth and allow for fusion with the
implantable prosthesis.
