Modular radial head prosthesis

1. A method for implanting a prosthesis system for replacement of a head portion of a proximal radius, comprising:

determining a distance between a proximal radius and a humerus;

selecting one of a first head component or a second head component based on the determination, the first and second head components having unique heights;

connecting the selected first or second head component to an articulation component by inserting a male insertion member formed on one of the articulation component and the selected head component into a female receiving member formed on the other of the articulation component and the selected head component; and

connecting a stem component to the selected first or second head component by slidably advancing a T-shaped protrusion formed on the stem component into a complementary shaped female slot formed on the male insertion member and aligning the complementary shaped female slot with another complementary shaped female slot formed on the head component.

2. The method of claim 1 wherein connecting the selected head component comprises:

slidably advancing a T-shaped protrusion formed on the stem component into a complementary shaped female slot formed on the head component.

3. The method of claim 1 wherein inserting the male insertion member into the female receiving member comprises:

compressing a portion of the male insertion member radially inwardly.

4. The method of claim 1 wherein inserting the male insertion member into the female receiving member comprises:

capturing a circumferential extension portion formed on the male insertion component with a reduced diameter portion formed in the female receiving member.

5. The method of claim 1 wherein connecting the stem component comprises:

extending a fastener into the T-shaped protrusion and into the selected head component.

6. The method of claim 5 wherein extending the fastener into the T-shaped protrusion comprises:

threadably engaging the fastener with the T-shaped protrusion.
