First Claim
1. An orthopaedic implant, comprising:
- an internal fixation device, said internal fixation device including;
an exterior surface;
a threaded section including a reservoir and at least one threaded section channel fluidly communicating said reservoir with said exterior surface of said internal fixation device;
a head including a head channel fluidly communicating with said reservoir, a channel diameter of said head channel being respectively larger than a largest interior diameter of each threaded section channel, said channel diameter of said head channel being the same as a large interior diameter of said reservoir; and
a tapered region between and fluidly communicating said head channel and said reservoir, said tapered region defining a tapered diameter which is less than said channel diameter of said head channel.

Abstract
An orthopedic implant includes an internal fixation device. The internal fixation device includes: an exterior surface; a threaded section including a reservoir and at least one threaded section channel fluidly communicating the reservoir with the exterior surface, each threaded section channel having an interior diameter and a length which is greater than the interior diameter; a head including a head channel fluidly communicating the reservoir with an exterior surface of the head, a channel diameter of the head channel being respectively larger than a largest interior diameter of each threaded section channel, the channel diameter of the head channel being the same as a large interior diameter of the reservoir; and a continuously tapering inner surface between the head channel and the reservoir.
