Purpose The aims of this study were to assess the function and quality of life after the Total Evolutive Shoulder System (TESS) reverse shoulder arthroplasty (RSA), to evaluate the radiological stability of the stemless version and to address the effect of arm lengthening and scapular notching (SN) on the outcome. Methods This was a prospective comparative nonrandomised study. A total of 37 consecutive patients (40 shoulders) underwent TESS RSA between October 2007 and January 2012; 16 were stemless and 26 were stemmed. At a mean follow-up of 39 months (15-66), we evaluated range of motion (ROM), pain and functional outcome with QuickDASH and quality of life with EQ-5D score. Radiologically, component positioning, signs of loosening, SN and arm length difference were documented. Results We found a significant improvement in functional outcome and reduction of pain in both stemmed and stemless groups. No humeral loosening was evident, but there were four glenoid loosenings. In 12 shoulders that developed SN, seven already had scapular bone impression (SBI) evident on initial post-operative radiographs. Glenoid overhang seemed to decrease the risk of SN. Arm lengthening was associated with better EQ-5D but did not influence ROM or functional outcome.Conclusions Reverse shoulder arthroplasty markedly improved shoulder function. SN is of concern in RSA, but proper positioning of the glenoid component may prevent its development.

“…4,33,43 Surgical/implant factors affecting outcomes include both technical factors (e.g., glenosphere positioning and tilt, humeral and glenosphere version) and implant-related factors (e.g., glenosphere diameter and lateral offset, humeral offset and rotation, polyethylene insert eccentricity, constraint and thickness). 3,9,16,[20][21][22][25][26][27][31][32][33] Surgeons should consider the effect of hardware selection and placement because excessive tension or offset after reverse arthroplasty may be associated with deltoid-related pain, restriction in motion, or acromial fractures. 8,14,34,42,50 To the contrary, insufficient tension or offset may be associated with instability or increased risk for scapular notching.…”

“…Prior clinical studies have shown scapular notching rates ranging from 0% to 96% in RSA [53]. Notching is usually apparent within the first few postoperative months and very few shoulders that have avoided notching by 12 months demonstrate notching later [28,42,54].…”

Abstract:Background: Anatomical shoulder replacement for rheumatoid arthritis (RA) is complicated by a high incidence of rotator cuff tears and glenoid erosion. This can lead to poor function and early failure. Reverse shoulder arthroplasty (RSA) has gained popularity as an alternative. This systematic review attempts to further define the role of RSA in RA.Methods: A systematic review identified seven studies reporting outcomes of RSA in RA patients. Studies were critically appraised, and data on outcomes, complications and technical considerations were extracted and analysed.Results: One hundred and twenty one shoulders were included (mean follow up 46.9 months). Consistent improvements in the main outcome measures were noted between studies. Ninety five percent of patients described excellent to satisfactory outcomes. The minimum mean forward elevation reported in each study was 115 degrees. Symptomatic glenoid loosening (1.7%), deep infection (3.3%) and revision surgery (5%) rates were no higher than for a population of mixed aetiologies.Discussion: Previous concerns regarding high pre-and peri-operative complication and revision rates in RA patients were not shown to be valid by the results of this review. Although associated cuff tears are common and glenoid bone loss can increase the technical complexity of surgery, RSA provides consistent and predictable improvements in key outcome measures and the revision and complication rates do not appear to be higher than reported in a large population of mixed aetiologies. Conclusion:The contemporary literature shows that RSA is a safe, effective and reliable treatment option in RA patients.
