Hypothesis and Background
Lateralizing the center of rotation in reverse shoulder arthroplasty (RSA) decreases the risk of scapular notching due to inferior impingement but may limit range of motion (ROM) in abduction and forward flexion related to superior acromial impingement. Our primary hypothesis was that, using a 3-dimensional (3D) computer model, a virtual acromioplasty (with or without tuberoplasty) could improve abduction and forward flexion following RSA for cuff tear arthritis (CTA) or massive cuff tear. Our secondary hypothesis was that, based on the virtual planning, a surgical acromioplasty could be performed safely during RSA, without increasing the risk of postoperative acromial fracture.
Methods
Eighty seven patients with CTA scheduled for RSA were analyzed with a 3D software and impingement-free ROM was measured. After virtual prosthesis implantation, early acromio-humeral impingement (abduction ≤ 80° or forward flexion ≤ 120°) was observed in 25% of the cases (22/87). A virtual acromioplasty (with or without tuberoplasty) was then performed and glenohumeral ROM was measured again. Based on this 3D planning, a surgical acromioplasty (with or without tuberoplasty) was performed to improve ROM in the vertical plane in these 22 patients with early acromial impingement. Patients were followed with minimum 24 months of follow-up to assess final shoulder ROM and complications.
Results
After virtual acromioplasty alone (n = 11) or acromioplasty with tuberoplasty (n = 11), glenohumeral abduction significantly increased from 75° ± 6.9 before to 89.5° ± 23.4, and forward flexion from 119.3° ± 12 to 135.2° ± 10 (P < .001). After surgical acromioplasty/tuberoplasty, the final mean global forward flexion was 148° ± 5 and mean global abduction 150° ± 8 in these patients. At last follow-up, no acromial fracture was observed.
Conclusion
In a 3D model, early acromial impingement may limit abduction (≤80°) or forward flexion (≤120°) after virtual RSA implantation for CTA or massive cuff tear. Virtual acromioplasty (with or without tuberoplasty) shows improved ROM in abduction and flexion. In patients with early impingement, a surgical acromioplasty can be performed safely during RSA, through a deltopectoral approach, without increasing the risk of postoperative acromial fracture.

Background
Scapular orientation may play an important role in preoperative planning for shoulder arthroplasty; however, there is currently no defined method for producing standardized three-dimensional measurements. The purpose of this study is to develop a reproducible measurement system of scapular orientation and to evaluate differences between unaffected shoulders and those with diagnoses of primary glenohumeral osteoarthritis (GHOA) and rotator cuff tear arthropathy (CTA).
Methods
Patients receiving computed tomography scans for preoperative shoulder arthroplasty planning were enrolled prospectively. Thin sliced axial images that included bilateral shoulders and the thorax were reformatted. The pathology of the bilateral glenohumeral joints was defined as GHOA, CTA, or unaffected. Scapular orientation was defined relative to the thorax using three-dimensional models to define the protraction, rotation, and tilt angles in the supine position. Univariate analysis was performed to compare demographics and scapular measurements between patients with GHOA, CTA, and unaffected shoulder pathology. Multivariate linear regression analysis was performed to identify independent predictors of scapular orientation.
Results
One hundred fifty-eight shoulders, comprising 79 patients were included. Twenty-seven percent (n = 21/79) of patients had an unaffected contralateral shoulder. Shoulders with GHOA had significantly greater downward scapular rotation (-14 ± 7 degrees) than both unaffected shoulders (-8 ± 7 degrees; P < .001) and those with CTA (-7 ± 8 degrees; P < .001). Increased downward scapular rotation was predicted by a shoulder pathology of GHOA in multivariate analysis (beta -7.09; P < .001). The magnitude of side-to-side difference was greatest in scapular rotation for patients with GHOA compared to CTA, with no significant differences in tilt or protraction.
Conclusion
Scapular rotation in the supine position varies by shoulder pathology, with greater downward rotation seen in patients with primary GHOA. These findings underscore the need for awareness of scapular orientation in addition to glenoid morphology when evaluating and planning shoulder arthroplasty cases.

Background
Sleep apnea (SA) has been shown to negatively affect cognition, immunity, and bone mineralization. There is conflicting evidence for the contribution of SA to outcomes following total shoulder arthroplasty. However, the impact of SA on reverse shoulder arthroplasty (RSA) has not been elucidated. A substantial increase in utilization of RSA is projected through the 2030s. Our objective was to assess postoperative medical and implant-related complications and healthcare utilization in patients with SA undergoing RSA.
Methods
A retrospective review of a private insurance claims database was conducted from 2010 to 2021. All cases of RSA and those with a prior diagnosis of SA were identified using their corresponding diagnosis and procedural codes. Patients undergoing RSA with a diagnosis of SA were matched to control patients 1:2 based on demographic and comorbidity profiles.
Results
A total of 18,229 SA patients were matched to 35,988 control patients. The SA cohort had significantly greater odds of all medical complications assessed compared to the control cohort. The SA cohort had greater odds of all implant-related complications including dislocation and mechanical loosening when compared to the control cohort. Mean length of stay was significantly greater in the SA group.
Conclusion
The current data demonstrate that SA patients may have an increased risk of complications and healthcare burden following RSA compared to RSA patients without SA. These findings indicate potential value in preoperative screening for SA prior to RSA.

Background
Three-dimensional, computed tomography preoperative planning has been increasingly adopted among shoulder arthroplasty surgeons. Prior studies have not examined outcomes in patients undergoing reverse total shoulder arthroplasty in which the surgeon implanted prostheses that deviated from the preoperative plan compared to patients in which the surgeon followed the preoperative plan. The hypothesis of this study was that clinical outcomes would not be different between patients in which the surgeon utilized components that deviated from those predicted in the preoperative plan and patients in which the surgeon followed the preoperative plan.
Methods
A retrospective review of patients that had preoperative planning for reverse total shoulder arthroplasty from April 2017 through February 2022 was performed. Patients were stratified into two groups: patients in which the surgeon utilized components that deviated from those anticipated by the preoperative plan (changed group), and patients in which the surgeon utilized all of the components anticipated by the preoperative plan (as planned group). Patient-reported outcomes including the Western Ontario Osteoarthritis Index, American Shoulder and Elbow Surgeons score, Single Assessment Numeric Evaluation, Simple Shoulder Test, and Shoulder Activity Level were recorded preoperatively, at one year, and at two years. Preoperative and one-year postoperative range of motion was recorded.
Results
One hundred and eighty-nine patients were included in this study. One hundred forty-seven patients had intraoperative changes to their preoperative plan and 42 patients underwent reverse total arthroplasty without changes to their preoperative plan. There was no difference determined between any patient-reported outcome score at the one- and two-year postoperative time points between the as planned group and the changed group. No differences were found in range of motion between groups. Patients initially planned to undergo anatomic total shoulder arthroplasty that were intraoperatively converted to a reverse total shoulder arthroplasty had equivalent outcomes compared to those that had 1) other intraoperative deviations or 2) had no changes to their original preoperative plan.
Conclusion
Patients undergoing reverse total shoulder arthroplasty that had an intraoperative deviation to the components utilized in the preoperative plan had equivalent 1) patient-reported outcomes at one and two years after surgery and 2) range of motion one year after surgery compared to those that did not change from the preoperative plan. This study suggests it is safe to make intraoperative changes to the components utilized in the preoperative plan without concern for inferior postoperative outcomes when performing reverse total shoulder arthroplasty.

Background
Reverse shoulder arthroplasty (RSA) has extended its indications in recent years to include complex proximal humerus fractures (PHFs) in elderly patients. The traditional approach in cases of PHF has been to cement the stem but, as in orthopedic surgery, the current trend in PHF is to avoid cementing the humeral stem as well.
Methods
We evaluated 63 patients (representing 63 shoulders) who underwent RSA with uncemented stem after acute fracture of the proximal humerus. We analyzed the clinical and radiological outcomes, as well as medium-term complications, using two different prosthesis models.
Results
The mean postoperative follow-up period was 21-23 months, and the mean age of the patients was 74.5 years. The average Constant Score was 56.94 points; there were no statistical significant differences in Constant Score depending on the prosthesis model used. No cases of aseptic loosening were observed. However, there was evidence of stress-shielding in prostheses with diaphyseal fixation, although this phenomenon did not appear to have functional or clinical consequences for the patients. Intraoperative complications occurred in 6.35% of cases, and postoperative complications were noted in 4.92%.
Conclusion
Based on the results of this study, we can affirm that the use of RSA with cementless stems in PHF can be a safe alternative, providing satisfactory clinical, functional, and radiographic results in the short term without the need to use cement in their fixation. The choice of prosthesis model may influence the occurrence of radiographic phenomena but does not seem to affect clinical outcome.

Background
Anatomic total shoulder arthroplasty (aTSA) and reverse total shoulder arthroplasty (rTSA) are proven surgical treatment options for both traumatic and degenerative conditions of the shoulder. Our objective is to report both clinical and patient-reported outcomes (PROs) of patients over the age of 75 at the time of arthroplasty. We hypothesize no functional difference in outcomes between patient groups.
Methods
Patients over the age of 75 at the time of surgery who received primary aTSA or rTSA between 2009 and 2020 with a minimum of two-year follow-up were selected. A retrospective chart review was performed. Patients 60-75 were included as a control group. 2:1 propensity matching using sex, Charlson Comorbidity Index, preoperative forward elevation (FE), and external rotation (ER) was used in selecting a comparison cohort of patients 60-75. Statistical analysis included the t-test, Wilcoxon signed-rank test, and chi-squared test.
Results
For aTSA, 25 patients older than 75 years fit the inclusion criteria. The mean follow-up time was 4.2 (2.0-12.0) years. aTSA patients over the age of 75 had significant improvements in FE 111 to 141 degrees (P = .007), ER 28 to 44 degrees (P < .001), and internal rotation (IR) sacrum to L4 (P = .003). There were also improvements in FE strength (FES) 4+/5 to 5/5 (P = .0303) and IR strength (IRS) but not ER strength (ERS) from 4+/5 to 5/5 (P = .098). There was no significant difference in range of motion (ROM), strength, or PROs between age groups (>75 years vs. 60-74 years). For rTSA, 47 patients older than 75 years fit the inclusion criteria. Average clinical follow-up was 3.5 (2.0-10.6) years. Patients demonstrated ROM improvements in ER (31 to 40 degrees, P = .0413), FE (96 to 138 degrees, P <.001) but not IR (L5 to L4, P = .3509). There were significant improvements in postoperative strength in FES (4-/5 to 4+/5, P <.001), ERS (4-/5 to 4+/5, P <.001), and IRS (4/5 to 5/5, P <.001). The only significant difference between propensity-matched age groups was postoperative IR (L4 to L5, P = .013). There were no significant differences in PROs between different age groups.
Conclusion
aTSA and rTSA provide significant improvements in ER, FE, ROM, ERS, FES, and IRS in patients over the age of 75 with no significant difference in outcomes compared to a younger cohort.

Background
The purpose of this investigation is to compare Cutibacterium acnes diagnosis using culturing vs. genomic DNA sequencing (NextGen) at various timepoints and locations during primary total shoulder arthroplasty. Additionally, we intend to compare the effects of hydrogen peroxide on standard culture technique results with genomic DNA sequencing.
Methods
A prospective diagnostic study of 40 patients undergoing primary total shoulder arthroplasty was performed. Intraoperatively, 4 tissue samples were collected per patient: subdermal skin edge following initial skin incision, subdermal skin edge following hydrogen peroxide soak for 5 minutes, glenohumeral joint capsule, and subdermal skin edge prior to wound closure. Each tissue specimen was collected twice (one for culture analysis and the other for genomic (NextGen) DNA sequencing analysis) for a total of 8 specimens per patient and 320 tissue specimens in total. All anaerobic cultures were held for 14 days. Each culture plate was divided into quadrants and the amount of growth was quantified. Tissue samples were collected for genomic sequencing DNA analysis. Genomic sequencing results provided relative percentage of bacteria for each specimen detected.
Results
There were 18/40 males (45%) and no postoperative complications. Average age was 72.2 ± 11.8. Overall, 18% (29/160) of standard anaerobic cultures were positive for C. Acnes and 26% (942/160) were positive with genomic (Nextgen) DNA sequencing. When comparing the NextGen results with anaerobic standard cultures, there was a calculated negative predictive value of 85.6% and positive predictive value of 28.6%. Sensitivity of the NextGen was 41.4% and specificity was 77.1%. Bacterial culture rates did not significantly change from the beginning to the end of surgery as demonstrated on standard culturing and the NextGen analysis (P > .05). After treatment with hydrogen peroxide, the standard culturing technique showed no significant difference between the samples; however, there was a significant increase in bacterial burden (12.4%) noted with NextGen analysis (P = .0147).
Conclusion
NextGen culturing is a novel technique to help identify shoulder prosthetic joint infections. These results show that, NextGen is better at identifying the absence of infection, but has a high false positive rate indicative of its ability to identify contaminants as compared to standard anaerobic culturing methods. The increase in bacterial burden after peroxide treatment noted with NextGen could also be secondary to the test’s increased ability to identify both living and dead bacterial pathogens.

Background
Glenohumeral arthritis in adults less than 40 years old represents a challenging clinical scenario to manage. While patients older than 55 have had reproducible success with current shoulder arthroplasty techniques, young patients have historically had less successful outcomes, possibly due to higher physical demands and more complex pathologies. Despite these concerns, anatomic total shoulder arthroplasty (TSA) remains the treatment of choice for young, active patients with severe glenohumeral arthritis and intact rotator cuff. We hypothesize that TSA provides significant relief in pain and functional outcomes in patients less than 40 years old.
Methods
We performed a single-institution retrospective analysis of consecutive patients aged 40 years and younger who underwent TSA between 2007 and 2022. Demographic data included age, sex, body mass index, Charlson comorbidity index, and preoperative diagnosis. Outcome measures included the Single-Assessment Numerical Evaluation (SANE) score, final range of motion, complications, and revision rate. Statistically significant differences between variables were evaluated using a 2-sample t-test at an α level of P < .05.
Results
Twenty-six TSAs were performed in 23 patients with an average final follow-up of 2 years after the procedure. The average age was 33.4 ± 5.3 years with a range of 19-39 years. The most common preoperative diagnosis was osteoarthritis (46%), followed by rheumatoid arthritis (27%) and osteonecrosis/avascular necrosis (19%). The most common glenoid morphology was type B (15) of which 14 were B2 glenoid, followed by type A (11). The SANE score, mean active forward elevation, abduction, external rotation, and internal rotation all improved significantly (P < .05) by the final follow-up. On average, patients in all groups were able to achieve minimal clinically important difference in SANE score after 1 year. There was 1 complication reported of an early postoperative infection treated with irrigation and débridement, and no revision surgeries were performed during the follow-up period.
Discussion/Conclusion
TSA significantly improved functional outcome measures in patients less than 40 years old with a low rate of complications and revisions in short-term outcomes. As the frequency of TSA continues to increase in adults less than 40 years old, additional studies recording long-term functional outcomes and implant survivorship in this population can be explored.
