Comparative Cohort Study

There are different techniques to address severe glenoid erosion during reverse shoulder arthroplasty (RSA). This study assessed the clinical and radiological outcomes of RSA with combined bony and metallic augment (BMA) glenoid reconstruction compared to bony augmentation (BA) alone. A review of patients who underwent RSA with severe glenoid bone loss requiring reconstruction from January 2017 to January 2019 was performed. Patients were divided into two groups: BMA versus BA alone. Clinical outcome measurements included two years postoperative ROM, Constant score, subjective shoulder value (SSV), and the American Shoulder and Elbow Surgeons Shoulder (ASES) score. Radiological outcomes included radiographic evidence of scapular complications and graft incorporation. The BMA group had significantly different glenoid morphology (p < 0.001) and greater bone loss thickness than the BA group (16.3 ± 3.8 mm vs. 12.0 ± 0.0 mm, p = 0.020). Both groups had significantly improved ROM (anterior forward flexion and external rotation) and clinical scores (Constant, SSV and ASES scores) at 2 years. Greater improvement was observed in the BMA group in terms of anterior forward flexion (86.3° ± 27.9° vs. 43.8° ± 25.6°, p = 0.013) and Constant score (56.6 ± 10.1 vs. 38.3 ± 16.7, p = 0.021). The BA group demonstrated greater functional and clinical improvements with higher postoperative active external rotation and ASES results (active external rotation, 49.4° ± 17.0° vs. 29.4° ± 14.7°, p = 0.017; ASES, 89.1 ± 11.3 vs. 76.8 ± 11.0, p = 0.045). The combination use of bone graft and metallic augments in severe glenoid bone loss during RSA is safe and effective and can be considered in cases of severe glenoid bone loss where bone graft alone may be insufficient.

Aims The aim of this study was to report the outcomes of different treatment options for glenoid loosening following reverse shoulder arthroplasty (RSA) at a minimum follow-up of two years. Patients and Methods We retrospectively studied the records of 79 patients (19 men, 60 women; 84 shoulders) aged 70.4 years (21 to 87) treated for aseptic loosening of the glenosphere following RSA. Clinical evaluation included pre- and post-treatment active anterior elevation (AAE), external rotation, and Constant score. Results From the original cohort, 29 shoulders (35%) were treated conservatively, 27 shoulders (32%) were revised by revision of the glenosphere, and 28 shoulders (33%) were converted to hemiarthroplasty. At last follow-up, conservative treatment and glenoid revision significantly improved AAE, total Constant score, and pain, while hemiarthroplasty did not improve range of movement or clinical scores. Multivariable analysis confirmed that conservative treatment and glenoid revision achieved similar improvements in pain (glenoid revision vs conservative, beta 0.44; p = 0.834) but that outcomes were significantly worse following hemiarthroplasty (beta -5.00; p = 0.029). Conclusion When possible, glenoid loosening after RSA should first be treated conservatively, then by glenosphere revision if necessary, and last by salvage hemiarthroplasty Cite this article: Bone Joint J 2019;101-B:461–469.

Abstract Introduction Reverse shoulder arthroplasty (RSA) has become a well-established treatment option for multiple disorders of the shoulder joint. In recent years, implant designs and configurations have been modified in order to improve function and avoid complications. Lateralization on the glenoid and the humeral side has been described to improve function and decrease radiographic scapular notching. Data on the clinical and radiographic results of bipolar lateralization in RSA are lacking. Methods In 38 cases, RSA was performed using an uncemented humeral short-stem component with a 145° neck–shaft angle in combination with bone lateralization on the glenoid side (Bony Increased-Offset Reversed Shoulder Arthroplasty, BIO-RSA; Wright Medical Inc., Memphis, TN, USA). Mean follow-up was 19 months (range 12–34 months). Patients were followed clinically using the Constant score as well as range of motion for shoulder flexion and external rotation. Radiographs in two different plains were analyzed for implant seating and the occurrence of scapular notching. Results There was a significant increase in all measured clinical parameters. Forward flexion increased from a mean of 75° preoperatively to 151° postoperatively, and mean Constant score increased from 21 to 71 points postoperatively (p < 0.001). Glenoid notching of grade 1 according to Sirveuax was observed in 3 out of 35 cases (9%); no grade 2, 3, or 4 notching was present. Revision surgery was necessary in one case (3%). Conclusion RSA with bipolar lateralization leads to excellent clinical outcomes, low complication rates, and low rates of radiographic scapular notching. Longer follow-up and prospective randomized trials are needed. Level of evidence Level IV.

Background Advances have been made to the traditional inlay Grammont Reverse Shoulder Arthroplasty (RSA) design such as the onlay humeral component prosthesis. Currently, there is no agreement in the literature regarding the best option for the humeral component when comparing inlay and onlay designs. This review compares the outcomes and complications between onlay versus inlay humeral components for RSA. Methods A literature search was conducted using PubMed and Embase. Only studies reporting outcomes comparing onlay versus inlay RSA humeral components were included. Results Four studies with 298 patients (306 shoulders) were included. Onlay humeral components were associated with better external rotation (ER) ( p < 0.0001). No significant difference in forward flexion (FF) or abduction was found. Constant scores (CS) and VAS scores did not differ. Increased scapular notching was found in the inlay group (23.18%) versus the onlay group (7.74%) ( p = 0.02). Postoperative scapular fractures and acromial fractures did not differ. Conclusion Onlay and inlay RSA designs are associated with improved postoperative range of motion (ROM). Onlay humeral designs may be associated with greater ER and lower rate of scapular notching; however, no difference was found in Constant and VAS scores, so further studies are required to assess the clinical significance of these differences.
