“…Regarding implant type, the results of this study were comparable to those of similar prostheses used for the same indication. First, the functional outcomes of the patients included in this study were consistent with the mean Constant scores reported in the literature [7,[24][25][26]. Second, the revision rate in this study (4.7%) was lower than that reported for similar prostheses both over comparable (7.3-25%) and longer follow-up periods (45%) [7,24,27].…”

Introduction Reverse total shoulder arthroplasty (RTSA) is a widely recognized treatment to reduce pain and improve shoulder function for patients in various disease stages of cuff tear arthropathy (CTA). However, it remains unclear whether outcomes after RTSA depend on the preoperative stage of CTA. Therefore, this study evaluated whether the Hamada classification influences midterm clinical outcomes after RTSA. Materials and methods In this multicenter observational study, patients underwent inverted bearing RTSA for massive rotator cuff tears or CTA. Shoulders were grouped into those with (Hamada grades 4a, 4b, and 5) and those without (Hamada grades 1, 2, and 3) glenohumeral arthritis. Clinical outcomes, including range of motion, Constant score, American Shoulder and Elbow Surgeons score, and visual analog scale for pain and satisfaction, were determined preoperatively and at 24 and > 30 months. All complications were recorded, and survival free from any implant component revision was calculated. Results Overall, 202 patients (211 shoulders) were treated with RTSA at a mean age of 75.8 ± 6.6 years (range 41.9–91.6 years). Of these, 144 patients (151 shoulders) were available for a mean follow-up of 79.9 ± 24.7 months (range 30.2–132.3 months). No significant between-group differences were found for clinical outcomes at 24 and > 30 months (P > 0.05). Furthermore, the Hamada classification did not correlate with clinical outcomes at 24 (P = 0.98) and > 30 months (P = 0.29). Revision-free implant component survival was similar between groups (P = 0.17). Postoperative complications were found in 11 shoulders, of which 10 required revision. Conclusions Inverted bearing RTSA was found to be an effective treatment with similarly good midterm clinical outcomes, similar revision rates, and high implant survival rates in every stage of massive rotator cuff tears. Overall, the preoperative Hamada classification did not influence clinical outcomes or complications after RTSA.

“…23,[29][30][31] Bone quality is an important factor to evaluate when considering stemless implants due to its direct interface with metaphyseal bone and its requirement for integration. 16,32 It has been recommended that only patients with good bone quality receive stemless implants. 33 This is due to the increased stress placed on and increased resorption of the available cancellous bone beneath the implant.…”

“…33 This is due to the increased stress placed on and increased resorption of the available cancellous bone beneath the implant. 11,29,[32][33][34] In patients with poor bone quality this can increase the risk of humerus fracture and cause implant failure. 34 Berth et al using SPECT/CT found higher bone uptake in the superior most region of the prosthesis.…”

Introduction: Anatomic total shoulder arthroplasty is the replacement of the humeral head and glenoid surfaces with the goal of replicating normal anatomy. It is commonly utilized for patients with osteoarthritis, rheumatoid arthritis, and osteonecrosis, who have decreased range of motion (ROM), persistent pain, and loss of strength. Total shoulder Arthroplasty (TSA) is the third most common joint replacement in the United States. The incidence of TSA has been increasing, some data suggest that by the year 2025, TSA incidence may rise to 439,206 operations per year. In recent years, stemless total shoulder implants have become available. Results: These implants preserve bone stock while decreasing complications such as osteolysis, stress shielding and periprosthetic fracture. Stemless implants improve anatomic reconstruction and biomechanical function of the shoulder joint. Conclusion: Increasing amounts of data suggest stemless TSA to be a safe and effective technology that will become more common in the coming year.

Langzeitergebnisse in der inversen Schulterendoprothetik Die inverse Schultertotalendoprothese (iSTEP) genießt seit einigen Jahren stetig wachsende Aufmerksamkeit. Seit der Einführung des Grammont-Konzepts weist sie gute klinische Ergebnisse auf und gilt als hervorragende Therapieoptionen für schmerzhafte, pseudoparalytische Schultern beim älteren Patienten. Schnell wurde die Indikationsstellung auf Omarthrose, Frakturen und Frakturfolgezustände, Revisionen und für Tumorpatienten erweitert. Die steigende Zahl an iSTEP-Implantationen lässt auf eine hohe Patientenzufriedenheit schließen. Doch wie lange hält die iSTEP tatsächlich stand und hält sie auch, was sie anfänglich verspricht?
