Interposition arthroplasty of the elbow

Interposition arthroplasty of the elbow was initially described in the 1880s to treat the stiff elbow resultant from infection, since when it has been advocated for a variety of pathological conditions of the elbow, including rheumatoid arthritis, haemophilic arthropathy and post-traumatic arthritis. Distraction using a dynamic external fixator has been advocated to stabilize the joint and protect the graft whilst allowing immediate post-operative movement. The literature concerning this surgery is limited, but this article reviews the results available and the methods used whilst attempting to summarize the changing indications and requirements for this procedure.
