Early results with the Delta Xtend shoulder arthroplasty as primary treatment or proximal humerus reoperation

Abstract

Reverse total shoulder arthroplasty (RTSA) has established itself as the standard of care for the treatment of rotator cuff arthropathy (RCA). Gradually, its share increased in relation to all used shoulder arthroplasties mainly in cases of complex proximal humeral fractures (PHFx).

Method: From November 2019 to December 2021, 39 patients at mean age of 72.8 years were operated via RTSA Delta Xtend by one surgeon in our clinic. 32 of them were followed for a period between 12 ÷ 30 months. At postoperative visits, function and pain were assessed using the Constant-Murley score (CMS), DASH score and recorded range of motion (ROM). Level of satisfaction was assessed using the visual analogue scale (VAS).

Results: The mean CMS recorded at the last visit was 82.6, and the relative one 90.8%. The achieved anterior elevation 145.9° and lateral elevation 136.6°. A significantly lower mean value of external rotation (39.8°) was found compared to the inner one (50.6°).

Conclusion: This study confirms those described by other authors promising early results with Delta Xtend RTSA. Longer follow-up is needed with a view to assessment of the dynamics of registered results, possible late complications and revision interventions.
