Interposition Arthroplasty of the Elbow

Abstract

Elbow arthrodesis is one of the most difficult and uncommonly performed reconstructive procedures at the elbow. Unfortunately, unlike arthrodesis of other joints, elbow arthrodesis tends to be a dysfunctional reconstructive option. Therefore, it is important to have the technique of elbow interposition arthroplasty in one’s armamentarium as it is the only viable functional reconstructive option for the younger active patient with end stage arthritis. In general, candidates for interposition arthroplasty are younger patients, less than 60 years old, with an activity level that exceeds the recommended restrictions imposed by the artificial elbow. While the objective outcomes are not impressive as a salvage procedure in young patients, the fact that almost 90% said they would undergo the procedure again based on their outcome prompts the continued use of this procedure in this clinical setting.
