Stemless total shoulder arthroplasty in elderly patients with primary osteoarthritis of shoulder – a developing country experience

Abstract

ABSTRACT Background We evaluated the imaging and functional outcomes of anatomic stemless shoulder arthroplasty (ECLIPSE) in elderly patients with primary osteoarthritis of the glenohumeral joint in Asian developing countries. Methods Thirty patients were treated using stemless TSA in 26 months period (years 2017 and 2019), and were followed for a minimum of 24 months. Functional outcomes were assessed using Constant and ASES scores. Radiolucent lines and osteopenia were analyzed on radiographs. Results Pre-surgery Constant and ASES scores improved from 27.33(21–38) and 29.67(22–38) to 68(54–78) and 71(71.4(56–79) at final follow up. Around the humeral component, one patient had calcar thinning and a radiolucent line thicker than 2 mm, while six patients had radiolucent lines less than 2 mm. The mean glenoid radiolucency score was 2± 1.1. Conclusion In our setting, stemless total shoulder arthroplasty demonstrated significant improvement in functional scores at short- to mid-term follow-up. Radiographic findings did not correlate with functional scores.
