Revision total elbow arthroplasty with the linked Coonrad-Morrey total elbow arthroplasty: a retrospective study of twenty procedures

Abstract

Purpose In this retrospective study we evaluated the shortto medium-term results after 20 Coonrad-Morrey revision total elbow arthroplasties (TEAs). Methods We included a consecutive series of revision TEAs performed at our institution from 2004 to 2010. At a mean follow-up of 4.4 years, patients were evaluated using the Mayo Elbow Performance Score (MEPS), the Oxford Elbow Score (OES) and standard radiographs. Results The mean age at revision TEA was 65.8 years. The median time of implant survival for primary prosthesis was 9.5 years. The mean post-operative MEPS was 79. The mean OES was 58, 66 and 53 for function, pain and social-psychological dimensions, respectively. At followup the range of motion had improved significantly. There were two cases of radiolucent lines and two cases of minor bushing wear; however, none of the implants were clinically loose. In one case deep infection led to a further revision. Two patients had post-operative ulnar nerve paraesthesia. Conclusions Results after revision TEA using the CoonradMorrey prosthesis are acceptable with a low short-to midterm failure rate. Revision improves range of motion and provides pain relief. One case of deep infection with recurrent revision is of concern. The treatment can be used as an option for failed TEA.

Arthroplasty Procedures for the Rheumatoid Elbow

“…The overall survival rate for primary TEA in a Danish study of 324 prostheses was 90 % at 5 years and 81 % at 10 years [ 9 ]. Furthermore, the relative risk for revision was increased when a non-linked design was implanted [ 9 ].…”

Total elbow arthroplasty is moving forward: Review on past, present and future

“…Besides, treatment of systemic diseases, such as rheumatoid arthritis has improved, with an overall increase in the quality of life, exposing TEA to a longer period of use. Results on TEA revision are promising; in a recent study revision led to pain relief and improved range of motion after failure of primary TEA [39] . The improved overall results might also question the need of postoperative functional restrictions, such as restricted lifting activities.…”
