“…The most important finding of this study was that, at a minimum follow-up of 2 years after RSA using the hybrid baseplate system, the postoperative CS was comparable to that reported in the recent meta-analysis by Nunes et al 18 and systematic review by Kennedy et al. 11 The findings of this study suggest that this new hybrid baseplate provides comparable clinical outcomes in the short term although longer follow-up studies are needed to confirm its survival and safety.…”

“…Furthermore, the most common complications in patients that had cuff tear arthropathy were acromial or scapular spine fractures (2%) and infection (1.6%), while in patients that had primary osteoarthritis, they were nerve palsy (2.3%) and infection (2%). The complication rate reported in the meta-analysis by Nunes et al 18 was stratified by the use of either metallic increased offset or BIO and found a complication rate of 0% to 56% for metallic increased offset and 0% to 14% for BIO. A recent systematic review by King et al 12 reported a 2.8% incidence of postoperative acromial and/or scapular spine fractures, while another systematic review by Patterson et al 19 reported a 4% complication rate.…”

“…The systematic review by Kennedy et al 11 reported a mean AFE of 130° after cuff tear arthropathy and 134° after primary osteoarthritis. The meta-analysis by Nunes et al 18 reported a mean AFE of 136° to 158°. Similarly, we found an ER of 29°; but when stratifying by preoperative diagnosis, the ER was 28° for the diagnosis of cuff tear arthropathy, while the ER was 34° for the diagnosis of primary osteoarthritis.…”

“…The recent systematic review by Kennedy et al 11 reported clinical outcomes and complications of RSA stratified by preoperative diagnosis, but without distinguishing between different RSA systems, and found postoperative CS of 60 to 74 for cuff tear arthropathy, compared to 65 to 88 for primary osteoarthritis. The recent meta-analysis by Nunes et al 18 compared lateralized to nonlateralized glenospheres in RSA and included 7 studies which used BIO-RSA and found postoperative CS of 61 to 69, with no difference between lateralized or nonlateralized glenospheres.…”

“…We, therefore, recommend that, for shoulders that require BIO-RSA, surgeons should avoid superior orientation, and manufacturers should consider developing a specific model of this hybrid baseplate, with a longer peg portion to increase the area of contact with the glenoid bone. In the meta-analysis by Nunes et al, 18 only 1 study was included in the forest plot on revision rates, reporting an incidence of 1.4%. 8 Mizuno et al 16 reported 4 patients with complications (15%); 1 patient had glenoid loosening (3.7%) which required revision, and 3 patients had nerve palsies (11%).…”

Background Despite the success of reverse shoulder arthroplasty (RSA), complication rates remain high (13% to 25%), due to instability, infection, and glenoid component loosening, which can lead to revision. The aim of the present study was to report the early clinical outcomes of RSA using a new hybrid baseplate design, in comparison with the literature on other common RSA baseplates. Methods The authors retrospectively analyzed the records of 142 patients (142 shoulders) who underwent primary RSA using a hybrid baseplate design by the senior surgeons between May 2014 and December 2018. Preoperative and postoperative assessments included the Constant score (CS) and range of motion, including active forward elevation, external rotation, and internal rotation. Results Of the initial cohort of 142 patients, 13 were lost to follow-up (8.6%), 2 died (1.3%), and 8 required reoperations with implant removal (5.3%). The remaining 119 patients comprised 71 women (60%) and 48 men (40%), aged 73.6 ± 7.3 years at index surgery, 43 of whom required bony increased offset (36%). At a minimum follow-up of 2 years, the CS improved by 37.3 ± 16.1, active forward elevation increased by 51.2° ± 38.1°, external rotation increased by 16.4° ± 25.0°, and internal rotation increased by 1.5 ± 3.2. Conclusion At a minimum follow-up of 2 years after RSA using a new hybrid baseplate system, the CS and range of motion were satisfactory and comparable to those in recent systematic reviews. The findings of this study suggest that this hybrid baseplate system provides satisfactory outcomes in the short term, although longer follow-up studies are needed to validate its long-term efficacy.

Objective The objective of this study was to evaluate clinical and radiological outcomes of a short stem reverse shoulder prosthesis with metaphyseal fixation specifically in older patients. Methods All patients, older than 70 years, submitted to a Reverse Shoulder Arthroplasty (RSA) using a cementless onlay short stem (Aequalis Ascend™ Flex Convertible Shoulder System (Stryker®)) from January 2017 to December 2021, with a minimum follow-up of 2 years, were included. Postoperative radiographs were assessed for stem loosening, subsidence, and varus-valgus tilt. Range of motion, visual analogue scale for pain, constant score, complication rate and revision rate were also analysed. Results A total of 34 patients with a mean age of 75 years (range 71–83 years) were submitted to a cementless onlay short stem RSA with a Bone Increased Off-Set (BIO-RSA) construct. The mean follow-up period was 61 months (range 54–87). Significant improvements (p < 0.001) were observed for the constant score and range of motion from the preoperative state to final follow-up. One case exhibited a significant varus deviation (> 5˚) during the follow-up period. No case of stem loosening was identified. There was only one case of complication because of post-traumatic dislocation, but the stem didn’t need revision. Conclusion Short stem RSA, even in patients older than 70 years, can yield a stable fixation with a good clinical and radiological outcome at short-medium term follow-up.
