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. An orthopaedic assembly comprising:

a first member adapted to be coupled to a bone, the first member being a fixation plate;

an adjustable connector assembly including an adjuster having a threaded end and a tapered end; and

an articulation component including a bearing surface and adapted to be coupled to the tapered end of the adjustable connector assembly;

wherein the threaded end is adapted to engage the fixation plate;

wherein the fixation plate includes a threaded throughbore and the adjustable connector further including a locking screw having external threads adapted to engage the first member; and

wherein the locking screw has a throughbore and the adjustable connector further includes an assembly screw adapted to fit through the throughbore of the locking screw.

2. The orthopaedic assembly of claim 1, wherein the adjuster includes a throughbore and the assembly screw is adapted to fit through the throughbore of the adjuster.

3. The orthopaedic assembly of claim 1, wherein the assembly screw includes a threaded end and the articulation component includes a threaded recess adapted to engage the threaded end.

4. The orthopaedic assembly of claim 1, wherein the adjustable connector further includes a collar, the collar having a tapered throughbore adapted to engage the tapered end of the adjuster.

5. The orthopaedic assembly of claim 4, wherein the collar is a plate having an outwardly extending flange.

6. The orthopaedic assembly of claim 4, wherein the collar includes an outer periphery having a locking taper and the articulating component having a tapered recess adapted to lock into the collar.

7. The orthopaedic assembly of claim 1, wherein the fixation plate has a plurality of fixation holes adapted to receive bone screws.
