Abstract

Background: The data on convertible total elbow arthroplasty are limited and primarily based on multiple centre/multiple surgeon series. The aim of this study was to report the mid-term functional outcomes, radiological findings, complications and survivorship of the Latitude total elbow arthroplasty performed by a single surgeon.

Study design & methods: The study included 13 patients (10 females, mean age of 72 years and varying indications) over eight years. The Oxford Elbow Score (OES), Mayo Elbow Performance Score (MEPS), range of movements (ROM), Subjective Elbow Value (SEV), satisfaction score (SS) and the revision rate of the implant per 100 observed component years (OCY) were assessed.

Results: The mean follow-up was 5.9 years (3-10 years). The Oxford Elbow Score/Mayo Elbow Performance Score improved from 15 to 42 (p value < 0.005)/26% to 93% (p value < 0.005) respectively. The arc of extension-flexion/supination-pronation improved from 63° to 106° (p = 0.00002)/123° to 142° (p = 0.32) respectively. The Subjective Elbow Value/Satisfaction Score was 83/98 respectively. There was one re-operation for a deep infection. There were no radiologic signs of loosening and the revision rate was 0.15 per 100 observed component years.

Conclusions: With careful patient selection, convertible total elbow arthroplasty provides patients with good to excellent outcomes and substantial improvements in the range of movements.
