Distal radioulnar joint implantation method

摘要

A system and method of implanting a distal wrist implant relative to a host bone is presented. A distal radial component having a body including a first connection portion couplable to a stem is coupled to a second prosthetic coupled to a medial surface of the body. The second prosthetic replaces at least a portion of the sigmoid notch.

1. A method of implanting a distal wrist implant relative to a host radius, the method comprising:
selecting a prosthetic head having a first coupling portion including opposing surfaces that define a slot, the head defining a passage that extends from an outer surface of the head to the slot, the head further defining a hole at a distal aspect thereof configured for receipt of one of a natural soft tissue replacement and an artificial soft tissue replacement; selecting a stem having a second coupling portion extending upwardly from a surface of the stem, the second coupling portion including first and second sides extending substantially parallel to each other; implanting the stem relative to the host radius; advancing the second coupling portion into the first coupling portion including aligning an angled wall on the second coupling portion with the hole in the head to accommodate receipt of said one of the natural and artificial soft tissue replacement between said angled wall and said head; and advancing a fastener through the passage in the prosthetic head and a bore in the stem.
