Aims The aim of this study was to evaluate the clinical and radiological outcome of using an anatomical short-stem shoulder prosthesis to treat primary osteoarthritis of the glenohumeral joint. Patients and Methods A total of 66 patients (67 shoulders) with a mean age of 76 years (63 to 92) were available for clinical and radiological follow-up at two different timepoints (T1, mean 2.6 years, sd 0.5; T2, mean 5.3 years, sd 0.7). Postoperative radiographs were analyzed for stem angle, cortical contact, and filling ratio of the stem. Follow-up radiographs were analyzed for timing and location of bone adaptation (cortical bone narrowing, osteopenia, spot welds, and condensation lines). The bone adaptation was classified as low (between zero and three features of bone remodelling around the humeral stem) or high (four or more features). Results The mean Constant score improved significantly from 28.5 (sd 11.6) preoperatively to 75.5 (sd 8.5) at T1 (p < 0.001) and remained stable over time (T2: 76.6, sd 10.2). No stem loosening was seen. High bone adaptation was present in 42% of shoulders at T1, with a slight decrease to 37% at T2. Cortical bone narrowing and osteopenia in the region of the calcar decreased from 76% to 66% between T1 and T2. Patients with high bone adaptation had a significantly higher mean filling ratio of the stem at the metaphysis (0.60, sd 0.05 vs 0.55, sd 0.06; p = 0.003) and at the diaphysis (0.65 sd 0.05 vs 0.60 sd 0.05; p = 0.007). Cortical contact of the stem was also associated with high bone adaptation (14/25 shoulders, p = 0.001). The clinical outcome was not influenced by the radiological changes. Conclusion Total shoulder arthroplasty using a short-stem humeral component resulted in good clinical outcomes with no evidence of loosening. However, approximately 40% of the shoulders developed substantial bone loss in the proximal humerus at between four and seven years of follow-up. Cite this article: Bone Joint J 2018;100-B:603–9.

Background Thus, the purpose of the present study was to (1) characterize common postoperative complications and (2) quantify the rates of revision in patients undergoing hemiarthroplasty to reverse total shoulder arthroplasty revisional surgery. We hypothesize that hardware loosenings will be the most common complication to occur in the sample, with the humeral component being the most common loosening. Methods This systematic review adhered to PRISMA reporting guideline. For our inclusion criteria, we included any study that contained intraoperative and/or postoperative complication data, and revision rates on patients who had undergone revision reverse total shoulder arthroplasty due to a failed hemiarthroplasty. Complications include neurologic injury, deep surgical site infections, hardware loosening/prosthetic instability, and postoperative fractures (acromion, glenoid, and humeral fractures). Results The study contained 22 studies that assessed complications from shoulders that had revision reverse total shoulder arthroplasty from a hemiarthroplasty, with a total sample of 925 shoulders. We found that the most common complication to occur was hardware loosenings (5.3%), and of the hardware loosenings, humeral loosenings (3.8%) were the most common. The revision rate was found to be 10.7%. Conclusion This systematic review found that revision reverse total shoulder arthroplasty for failed hemiarthroplasty has a high overall complication and reintervention rates, specifically for hardware loosening and revision rates.

Background: This technique video reviews anatomic total shoulder arthroplasty (TSA) with a stemless humeral component using a representative case example. Indications: Stemless TSA is indicated for patients with symptomatic glenohumeral arthritis typically younger than 65 years of age. Stemless TSA may be used for other glenohumeral degenerative conditions such as avascular necrosis or posttraumatic arthropathy, provided acceptable humeral bone quality is confirmed intraoperatively using a thumb-press test. Poor bone quality is the primary contraindication. Technique Description: Preoperatively, computed tomography is typically used for planning, and intraoperative navigation through magnetic resonance imaging is also useful. The procedure’s critical elements include beach chair positioning, standard deltopectoral approach with lesser tuberosity osteotomy (LTO), freehand proximal humeral osteotomy, perpendicular proximal humeral exposure and subsequent preparation over a central guidewire, stemless implant and humeral head sizing, perpendicular glenoid exposure and implant placement, and final humeral implantation with LTO repair/fixation. A phased rehabilitation protocol includes 6-week sling immobilization to protect the subscapularis/LTO repair and return to normal activities between 3 and 6 months postoperatively. Discussion/Conclusion: Stemless TSA shows promising early and mid-term outcomes with complication rates, including humeral loosening rates, similar to standard stemmed components. Potential complications include neurovascular injury, infection, glenoid or humeral component loosening, and rotator cuff failure.

Early Fixation

Aims Stemless humeral implants have been developed to overcome stem-related complications in total shoulder arthroplasty (TSA). However, stemless implant designs may hypothetically result in less stable initial fixation, potentially affecting long-term survival. The aim of this study is to investigate early fixation and migration patterns of the stemless humeral component of the Simpliciti Shoulder System and to evaluate clinical outcomes. Methods In this prospective cohort study, radiostereometric analysis (RSA) radiographs were obtained in 24 patients at one day, six weeks, six months, one year, and two years postoperatively. Migration was calculated using model-based RSA. Clinical outcomes were evaluated using the visual analogue scale (VAS), the Oxford Shoulder Score (OSS), the Constant-Murley Score (CMS), and the Disabilities of the Arm, Shoulder and Hand (DASH) score. Results At two years, median translation along the x-, y-, and z-axis was -0.12 mm (interquartile range (IQR) -0.18 to 0.02), -0.17 mm (IQR -0.27 to -0.09), and 0.09 mm (IQR 0.02 to 0.31). Median rotation around the x-, y-, and z-axis was 0.12° (IQR -0.50 to 0.57), -0.98° (IQR -1.83 to 1.23), and 0.09° (IQR -0.76 to 0.30). Overall, 20 prostheses stabilized within 12 months postoperatively. Four prostheses showed continuous migration between 12 and 24 months. At two-year follow-up, with the exception of one revised prosthesis, all clinical scores improved significantly (median VAS difference at rest: -3.0 (IQR -1.5 to -6.0); OSS 22.0 (IQR 15.0 to 25.0); CMS 29.5 (IQR 15.0 to 35.75); and DASH -30.0 (IQR -20.6 to -41.67) (all p < 0.001)) with the exception of one revised prosthesis. Conclusion In conclusion, we found that 20 out of 24 implants stabilized within 12 months postoperatively. The significance of continuous migration in four implants is unclear and future research on the predictive value of early migration for future loosening in TSA is required. Clinical results revealed a clinically relevant improvement. Cite this article: Bone Joint J 2022;104-B(1):76–82.
