Abstract

An orthopaedic assembly. The orthopaedic assembly includes a first member adapted to be coupled to a bone and an adjustable connector assembly including an adjuster having a threaded end and a tapered end. The assembly also includes an articulation component including a bearing surface and adapted to be coupled to the tapered end of the adjustable connector assembly. The threaded end is adapted to engage the fixation plate.

Claims

1-20. -20. (canceled)

21. A method of repairing a fractured end of a bone, the method comprising:

removing fractured portions of an articulating bone surface at the end of a bone;

securing a fixation plate to a lateral surface of the fractured end of the bone, the fixation plate being coupled to an adjustable connector assembly including an adjuster having a threaded end and a tapered end;

coupling an articulation component to the tapered end of the adjuster;

threading the adjuster into or out of a threaded bore of the fixation plate to adjust the length of the adjuster extending from the bore of the fixation plate; and

locking the position of the adjuster within the threaded bore.

22. The method of claim 21, further comprising coupling an articulation component to the tapered end of the adjuster.

23. The method of claim 22, wherein the coupling an articulation component to the tapered end of the adjuster includes inserting a collar over the tapered end of the adjuster and inserting the articulation component onto an outer side of the collar.

24. The method of claim 21, wherein locking the position of the adjuster within the threaded bore includes threading a locking screw into the threaded bore.

25. The method of claim 24, further comprising inserting an assembly screw through the locking screw and the adjuster.

26. The method of claim 25, wherein the inserting an assembly screw includes inserting a threaded end of the assembly screw through the locking screw and the adjuster.

27. The method of claim 26, further comprising threading the threaded end of the assembly screw into a threaded recess of the articulation component.
