Unlinked, linked and convertible total elbow arthroplasties (TEAs) are currently available. This study is the first to report the clinical results of the convertible Latitude TEA. This was a retrospective study of a consecutive cohort of 63 patients (69 primary TEAs) with a mean age of 60 years (23 to 87). Between 2006 and 2008 a total of 19 men and 50 women underwent surgery. The mean follow-up was 43 months (8 to 84). The range of movement, function and pain all improved six months post-operatively and either continued to improve slightly or reached a plateau thereafter. The complication rate is similar to that reported for other TEA systems. No loosening was seen. Remarkable is the disengagement of the radial head component in 13 TEAs (31%) with a radial head component implanted. Implantation of both the linked and the unlinked versions of the Latitude TEA results in improvement of function and decreased pain, and shows high patient satisfaction at mid-term follow-up.

Background: Purpose of this study was to evaluate the longterm survivorship and clinical and radiological results of a primary reverse total shoulder arthroplasty (RTSA) performed with uncemented stems. Methods: From 2001 until 2006 61 primary uncemented RTSAs were implanted, which were included in a Kaplan-Meier survival analysis. Range of motion, functional scores and radiological followup was obtained. 27 patients were available for followup. Mean follow-up was 9.2 years (SD 2.4). Results: Mean cumulative survival was 82.4% (95% CI: 50.7-94.6%) of the total construct and 98.3% (CI: 88.8-98.8%) of the uncemented humeral stem after 12.5 years. Five revisions occurred (8.2%). Mean anteflexion improved from 69.3 to 111.9°(p < 0.0001), lateral elevation from 65.9 to 101.3°(p < 0.0001), Constant-Murley score from 39.1 to 66.9 (p < 0.0001), Simple Shoulder Test from 1.5 to 7.1 (p < 0.0001), and VASpain from 65.5 to 6.6 at final follow-up (p = 0.0003). Scapular notching was present in 94.1% of the patients. Conclusions: The present study shows that the long-term clinical results of the primary Delta III RTSA seem very encouraging and survivorship of, in particular, its uncemented humeral stem is good.

BackgroundNew surgical approaches have been developed to optimise elbow function after total elbow arthroplasty (TEA). Currently, there is no consensus on the best surgical approach. This study aims to investigate the functional outcomes, prosthetic component position and complication rates after a triceps-sparing and a triceps-detaching approach in TEA.Methods and analysisA multicentre prospective comparative cohort study will be conducted. All patients with an indication for primary TEA will enrol in either the triceps-sparing or the triceps-detaching cohort. Primary outcome measure is elbow function, specified as fixed flexion deformity. Secondary outcome parameters are self-reported and objectively measured physical functioning, including triceps force, prosthetic component position in standard radiographs and complications.DiscussionThe successful completion of this study will clarify which surgical approach yields better functional outcomes, better prosthetic component position and lower complication rates in patients with a TEA.Ethics and disseminationThe Medical Ethics Review Board of University Medical Center Groningen reviewed the study and concluded that it is not clinical research with human subjects as meant in the Medical Research Involving Human Subjects Act (WMO), therefore WMO approval is not needed (METc2019/544).Trial registration numberNTR NL8488.
