Systematic review of primary total elbow prostheses used for the rheumatoid elbow.

Total elbow prosthesis (TEP) has been shown to be a viable option for treatment of the rheumatoid elbow. Many types of TEP have been studied, but the heterogeneity of the studies makes most conclusions subject to discussion. The aim of this systematic review is to show the differences between the most commonly used TEP for the destroyed rheumatoid elbow. After a search in Pubmed (NLM, Bethesda, USA) the senior author selected eight frequently used TEP: the Capitellocondylar, Coonrad-Morrey, GSB III, Kudo, Liverpool, Norway, Roper-Tuke and Souter-Strathclyde. For inclusion studies we arbitrarily formulated nine criteria, after which clearly adverse events were defined for comparison purposes. The Capitellocondylar and Souter-Strathclyde prostheses are the most-studied treatments for replacing the rheumatoid elbow. In contrast to the Capitellocondylar, the Souter-Strathclyde prosthesis showed higher loosening rates but implemented modifications of the design have reduced these rates in recent studies. Nevertheless, in relation to most other joint replacements in rheumatoid patients, all TEP still have higher complication rates. For this reason an elbow prosthesis may just be warranted in seriously disabled patients.
