Abstract

A method of implanting a humeral component includes accessing a humerus and resecting a head portion of the humerus to form a resected surface. The method further includes selecting a first combination sizer and guide device having an outer surface sized complementary to a desired implant head size, positioning the selected first combination sizer and guide device on the resected surface, guiding placement of a guide pin in the humerus with the first combination sizer and guide device, guiding a reamer with the placed guide pin to form a reamed cavity in the humerus, positioning an anchoring portion of a humeral implant base portion in the reamed cavity, positioning the first combination sizer and guide device on the base portion, removing the first combination sizer and guide device from the base portion, and positioning an implant head on the base portion.

Claims (24)

1. A method of implanting a humeral component comprising:

accessing a humerus;

resecting a head portion of the humerus to form a resected surface;

selecting a first combination sizer and guide device having an outer surface sized complementary to a desired implant head size;

positioning the selected first combination sizer and guide device on the resected surface;

guiding placement of a guide pin in the humerus with the first combination sizer and guide device positioned on the resected bone;

guiding a reamer with the placed guide pin to form a reamed cavity in the humerus;

positioning an anchoring portion of a humeral implant base portion in the reamed cavity;

positioning the first combination sizer and guide device on the positioned base portion;

removing the first combination sizer and guide device from the positioned base portion; and

positioning an implant head on the positioned base portion.

2. The method of claim 1 , wherein selecting the first combination sizer and guide device comprises:

selecting the first combination sizer and guide device from a group of differently sized sizer and guide combination devices.

3. The method of claim 2 , wherein positioning the anchoring portion comprises:

guiding the anchoring portion with the guide pin.

4. The method of claim 1 , further comprising:

performing a trial reduction with the first combination sizer and guide device positioned on the positioned base portion.

5. The method of claim 4 , further comprising:

selecting the implant head from a group of differently sized implant heads based upon the trial reduction.

6. The method of claim 1 , wherein positioning the first combination sizer and guide device on the positioned base portion comprises:

inserting a taper-lock mounting portion of the positioned base portion in a non-taper-lock cavity of the first combination sizer and guide device.

7. The method of claim 1 , further comprising:

threadedly engaging the humerus with a threaded portion of the base portion; and

guiding the base portion with the placed guide pin while threadedly engaging the humerus with the threaded portion of the base portion.
