Abstract Background The introduction of reverse total shoulder arthroplasty (RSA) as a treatment option in complex proximal humeral fractures, has significantly extended the surgical armamentarium. The aim of this study was to investigate the mid-term outcome following fracture RSA in acute or sequelae, as well as salvage procedures. It was hypothesized that revision RSA (SRSA) leads to similar mid-term results as primary fracture treatment by RSA (PRSA). Methods This retrospective study describes the radiological and clinical mid-term outcomes in a standardized single-centre and Inlay design. Patients who underwent RSA in fracture care between 2008 and 2017 were included (minimum follow-up: 2 years, minimum age: 60 years). The assessment tools used for functional findings were range of motion (ROM), Visual Analogue Scale, absolute (CS) plus normative Constant Score, QuickDASH, and Subjective Shoulder Value. All adverse events as well as the radiological results and their clinical correlations were statistically analysed (using p < .05and 95% confidence intervals). Results Following fracture RSA, 68 patients were included (mean age: 72.5 years, mean follow-up: 46 months). Forty-two underwent primary RSA (PRSA), and 26 underwent revision RSA (SRSA). Adverse advents were observed in 13% (n = 9/68). No statistically significant results were found for the scores of the PRSA and SRSA groups, while the failed osteosynthesis SRSA subgroup obtained statistically significantly negative values for ROM subzones (flexion: p = .020, abduction: p = .020). Decreased instances of tubercle healing were observed for the in PRSA group relative to the SRSA group (p = .006). The absence of bony healing of the tubercles was related to significant negative clinical and subjective outcomes (all scores: p < .05, external rotation: p= .019). Significant postoperative improvements were evaluated in the SRSA group (CS: 23 to 56 at mean, p = .001), the time from index surgery to operative revision revealed no associations in functional findings. Conclusions RSA is an effective option in severe shoulder fracture management with predictable results for salvage as well as first-line treatment. Promising mid-term functional results, reasonable implant survival rates, and high patient satisfaction can be achieved. Level of evidence Level III.

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 In a reverse total shoulder arthroplasty, the altered glenohumeral joint center of rotation subjects the glenoid baseplate to increased shear forces and potential loosening. Methods This study examined glenoid baseplate micromotion and initial fixation strength with the application of direct shear force in a Sawbone model. The reverse total shoulder arthroplasty systems examined were the DJO Reverse® Shoulder Prosthesis, the Exactech Equinoxe® Reverse System, and the Tornier AequalisTM Reverse Shoulder Prosthesis. Specimens were cyclically tested with increasing shear loads until 150 µm of displacement between the implant and glenoid was achieved, and subsequently until failure, classified as either 1 cm of implant/glenoid displacement or fracture. Results The average load withstood for the 150 µm threshold for DJO, Tornier, and Exactech was 460 ± 88 N, 525 ± 100 N, and 585 ± 160 N, respectively. The average total load at device failure for DJO, Tornier, and Exactech was 980 ± 260 N, 1260 ± 120 N, and 1350 ± 230 N, respectively. Discussion The Exactech implant design trended toward requiring more load to induce micromotion at each threshold and to induce device failure, most commonly seen as inferior screw pull out. This study proposes design features that may enhance fixation and suggests little risk of initial micromotion or failure during initial post-operative recovery.
