RESUMEN
BACKGROUND: The design of reverse shoulder arthroplasty (RSA) implants has evolved significantly over the past 50 years. Today there are many options available that differ in design of the glenoid and humeral components, fixation methods, sizes, and modularity. With respect to the humeral component, the literature has generally focused on the differences between inlay and onlay designs and the potential impact on outcomes. However, inlay and onlay design represents only one factor of many. METHODS: It is our hypothesis that separating onlay and inlay designs into 2 distinct entities is an oversimplification as there can be a wide overlap of the 2 designs, depending on surgical technique and the implant selected. As such, the differences between inlay and onlay designs should be measured in absolute terms-meaning combined distalization and lateralization. RESULTS: By reviewing the many factors that can contribute to the glenosphere-humerus relationship, the role of inlay and onlay humeral designs as an important distinguishing feature is shown to be limited. Preliminary studies suggest that the amount of distalization and lateralization of the construct may be the most accurate method of describing the differences in the constructs. CONCLUSIONS: Inlay and onlay humeral component design represents only one factor of many that may impact outcomes. A more accurate method of defining specific design and technique factors in RSA is the degree of lateralization and distalization.

BACKGROUND: The purpose of this study was to define the optimal combination of surgical technique and postoperative rehabilitation protocol for elderly patients undergoing either hemiarthroplasty (HA) or reverse total shoulder arthroplasty (rTSA) for acute proximal humerus fracture (PHF) by performing a network meta-analysis of the comparative studies in the literature. METHODS: A systematic review of the literature using Preferred Reporting Items for Systematic Reviews and Meta-analyses guidelines of MEDLINE, EMBASE, and Cochrane Library was screened from 2007 to 2023. Inclusion criteria were level I-IV studies utilizing primary HA and/or rTSA published in a peer-reviewed journal, that specified whether humeral stems were cemented or noncemented, specified postoperative rehabilitation protocol, and reported results of HA and/or rTSA performed for PHF. Early range of motion (ROM) was defined as the initiation of active ROM at ≤3 weeks after surgery. Level of evidence was evaluated based on the criteria by the Oxford Centre for Evidence-Based Medicine. Clinical outcomes were compared using a frequentist approach to network meta-analysis with a random-effects model that was performed using the netmeta package version 0.9-6 in R. RESULTS: A total of 28 studies (1119 patients) were included with an average age of 74 ± 3.7 and mean follow-up of 32 ± 11.1 months. In the early ROM cohort (Early), the mean time to active ROM was 2.4 ± 0.76 weeks compared to 5.9 ± 1.04 weeks in the delayed ROM cohort (Delayed). Overall, rTSA-Pressfit-Early resulted in statistically superior outcomes including postoperative forward elevation (126 ± 27.5), abduction (116 ± 30.6), internal rotation (5.27 ± 0.74, corresponding to L3-L1), American Shoulder and Elbow Surgeons score (71.8 ± 17), tuberosity union (89%), and lowest tuberosity nonunion rate (9.6%) in patients ≥65 year old with acute PHF undergoing shoulder arthroplasty (all P ≤ .05). In total there were 277 (14.5%) complications across the cohorts, of which 89/277 (34%) were in the HA-Cement-Delayed cohort. HA-Cement-Delayed resulted in 2-times higher odds of experiencing a complication when compared to rTSA-Cement-Delayed (P = .005). Conversely, rTSA-Cement-Early cohort followed by rTSA-Pressfit-Early resulted in a total complication rate of 4.7% and 5.4% (odds ratios, 0.30; P = .01 & odds ratios, 0.42; P = .05), respectively. The total rate of scapular notching was higher in the cemented rTSA subgroups (16.5%) vs. (8.91%) in the press fit rTSA subgroups (P = .02). CONCLUSION: Our study demonstrates that patients ≥65 years of age, who sustain a 3-or 4-part PHF achieve the most benefit in terms of ROM, postoperative functional outcomes, tuberosity union, and overall complication rate when undergoing rTSA with a noncemented stem and early postoperative ROM when compared to the mainstream preference-rTSA-Cement-Delayed.
RESUMEN
BACKGROUND: The incidence of proximal humerus fractures (PHF) is continuing to rise due to shifts towards a more aged population as well as advancements in surgical treatment options. The purpose of this study is to examine and compare trends in the treatment of PHFs (nonoperative vs. operative; different surgical treatments) across different age groups over the last decade (2010-2020). METHODS: The New York Statewide Planning and Research Cooperative System (SPARCS) database was queried using International Classification of Diseases and Current Procedural Terminology codes to identify all patients presenting with or undergoing surgery for PHF between 2010 and 2020. Treatment trends, demographics, and insurance information were analyzed during the study period. Comparisons were made between operative and nonoperative trends with respect to the number and type of surgeries performed among 3 age groups: ≤49 years, 50-64 years, and ≥65 years. The rate of postoperative complications and reoperations was evaluated and compared among different surgical treatments for patients with a minimum 1-year postoperative follow-up. RESULTS: A total of 92,308 patients with a mean age of 67.8 ± 16.8 years were included. Over the last decade, there was no significant increase in the percentage of PHFs treated with surgery. A total of 15,523 PHFs (16.82%) were treated operatively, and these patients, compared with the nonoperative cohort, were younger (64.9 years vs. 68.4 years, P < .001), more likely to be White (80.2% vs. 74.7%, P < .001), and more likely to have private insurance (41.4% vs. 32.0%, P < .001). For patients ≤49 years old, trends in operative treatment have remained stable with internal fixation (IF) as the most used surgical modality. For patients 50-64 years old, we observed a gradual decline in the use of hemiarthroplasty (HA), with a corresponding increase in the use of reverse total shoulder arthroplasty (rTSA), but IF continued to be the most used operative modality. In patients over 65 years, a steep decline in the use of IF and HA was noted during the first half of the decade along with a significant exponential increase in the use of rTSA, which surpassed the use of IF in 2019. Despite the increase in the use of rTSA, no differences in rate of surgical complications were noted between rTSA and IF (χ2 = 0.245, P = .621) or reoperations (χ2 = 0.112, P = .730). CONCLUSION: Nonsurgical treatment remains the mainstay treatment of PHFs. Although there is no increase in the prevalence of operative treatment in patients ≥50 years in the last decade, there is an exponential increase in the use of rTSA with a corresponding decrease in HA and IF, a trend more substantial in patients ≥65 years compared with patients between 50 and 64 years.

INTRODUCTION: Though Patient-Reported Outcomes Measurement Information System (PROMIS) Upper Extremity (P-UE) has been validated in upper extremity orthopedics, it's ability to capture a patient's functional recovery after arthroscopic rotator cuff repair (aRCR), as measured by its responsiveness, is minimal in the early postoperative period. The primary purpose of this study is to determine if addition of PROMIS Pain Intensity (P-Intensity) or Pain Interference (P-Interference) scores to PROMIS UE improves the responsiveness throughout the one-year postoperative period after aRCR. METHODS: This prospective, longitudinal study included 100 patients who underwent aRCR. Patients completed P-UE, P-Interference, P-Intensity, American Shoulder and Elbow Surgeons (ASES), and Western Ontario Rotator Cuff Index (WORC) scores preoperatively and at 2-weeks, 6-weeks, 3 months, 6-months and 12-months after surgery. Responsiveness at each time-point relative to preoperative baseline and one-way analysis of variance with post-hoc analysis was conducted for each PROM. Responsiveness of the outcome score was determined using the effect size (ES), graded as small (0.2), medium (0.5), or large (0.8). The Pearson correlation coefficient (r) was determined between these instruments at each time-point. RESULTS: In isolation, P-UE, P-Interference, and P-Intensity showed a medium-large ability to detect change (positive and negative) throughout the one-year postoperative period. The addition of PROMIS pain scores to P-UE improved the responsiveness of the instrument (from medium to a large effect size) starting at 3 months and continued throughout the 12 month follow-up period. Though the addition of pain scores increases the response burden for PROMIS, this was still lower when compared to the response burden for the legacy outcome scores (p<0.05). CONCLUSION: The addition of PROMIS pain instruments improves the responsiveness of the P-UE function score in patients undergoing aRCR.
RESUMEN
BACKGROUND: The Walch classification is commonly used by surgeons when determining the treatment of osteoarthritis (OA). However, its utility in prognosticating patient clinical state before and after TSA remains unproven. We assessed the prognostic value of the modified Walch glenoid classification on preoperative clinical state and postoperative clinical and radiographic outcomes in total shoulder arthroplasty (TSA). METHODS: A prospectively collected, multicenter database for a single-platform TSA system was queried for patients with rotator cuff-intact OA and minimum 2 year follow-up after anatomic (aTSA) and reverse TSA (rTSA). Differences in patient-reported outcome scores (Simple Shoulder Test, American Shoulder and Elbow Surgeons Standardized Shoulder Assessment Form, Shoulder Pain and Disability Index, visual analog scale for pain, Shoulder Function score), combined patient-reported and clinical-input scores (Constant, University of California-Los Angeles shoulder score, Shoulder Arthroplasty Smart Score), active range of motion values (forward elevation [FE], abduction, external rotation [ER], internal rotation [IR], and radiographic outcomes (humeral and glenoid radiolucency line rates, scapula notching rate) were stratified and compared by glenoid deformity type per the Walch classification for aTSA and rTSA cohorts. Comparisons were performed to assess the ability of the Walch classification to predict the preoperative, postoperative, and improved state after TSA. RESULTS: 1008 TSAs were analyzed including 576 aTSA and 432 rTSA. Comparison of outcomes between Walch glenoid types resulted in 15 pairwise comparisons of 12 clinical outcome metrics, yielding 180 total Walch glenoid pairwise comparisons for each clinical state (preoperative, postoperative, improvement). Of the 180 possible pairwise Walch glenoid type and metric comparisons studied for aTSA and rTSA cohorts, <6% and <2% significantly differed in aTSA and rTSA cohorts, respectively. Significant differences based on Walch type were seen after adjustment for multiple pairwise comparisons in the aTSA cohort for FE and ER preoperatively, the Constant score postoperatively, and for abduction, FE, ER, Constant score, and SAS score for pre- to postoperative improvement. In the rTSA cohort, significant differences were only seen in abduction and Constant score both postoperatively and for pre- to postoperative improvement. There were no statistically significant differences in humeral lucency rate, glenoid lucency rate (aTSA), scapular notching rate (rTSA), complication rates, or revision rates between Walch glenoid types after TSA. CONCLUSION: Although useful for describing degenerative changes to the glenohumeral joint, we demonstrate a weak association between preoperative glenoid morphology according to the Walch classification and clinical state when evaluating patients undergoing TSA for rotator cuff-intact OA. Alternative glenoid classification systems or predictive models should be considered to provide more precise prognoses for patients undergoing TSA for rotator cuff-intact OA.

BACKGROUND: Clinical significance, as opposed to statistical significance, has increasingly been utilized to evaluate outcomes after total shoulder arthroplasty (TSA). The purpose of this study was to identify thresholds of the minimal clinically important difference (MCID), substantial clinical benefit (SCB), and patient acceptable symptomatic state (PASS) for TSA outcome metrics and determine if these thresholds are influenced by prosthesis type (anatomic or reverse TSA), sex, or preoperative diagnosis. METHODS: A prospectively collected international multicenter database inclusive of 38 surgeons was queried for patients receiving a primary aTSA or rTSA between 2003 and 2021. Prospectively, outcome metrics including ASES, shoulder function score (SFS), SST, UCLA, Constant, VAS Pain, shoulder arthroplasty smart (SAS) score, forward flexion, abduction, external rotation, and internal rotation was recorded preoperatively and at each follow-up. A patient satisfaction question was administered at each follow-up. Anchor-based MCID, SCB, and PASS were calculated as defined previously overall and according to implant type, preoperative diagnosis, and sex. The percentage of patients achieving thresholds was also quantified. RESULTS: A total of 5851 total shoulder arthroplasties (TSAs) including aTSA (n = 2236) and rTSA (n = 3615) were included in the study cohort. The following were identified as MCID thresholds for the overall (aTSA + rTSA irrespective of diagnosis or sex) cohort: VAS Pain (-1.5), SFS (1.2), SST (2.1), Constant (7.2), ASES (13.9), UCLA (8.2), SPADI (-21.5), and SAS (7.3), Abduction (13°), Forward elevation (16°), External rotation (4°), Internal rotation score (0.2). SCB thresholds for the overall cohort were: VAS Pain (-3.3), SFS (2.9), SST 3.8), Constant (18.9), ASES (33.1), UCLA (12.3), SPADI (-44.7), and SAS (18.2), Abduction (30°), Forward elevation (31°), External rotation (12°), Internal rotation score (0.9). PASS thresholds for the overall cohort were: VAS Pain (0.8), SFS (7.3), SST (9.2), Constant (64.2), ASES (79.5), UCLA (29.5), SPADI (24.7), and SAS (72.5), Abduction (104°), Forward elevation (130°), External rotation (30°), Internal rotation score (3.2). MCID, SCB, and PASS thresholds varied depending on preoperative diagnosis and sex. CONCLUSION: MCID, SCB, and PASS thresholds vary depending on implant type, preoperative diagnosis, and sex. A comprehensive understanding of these differences as well as identification of clinically relevant thresholds for legacy and novel metrics is essential to assist surgeons in evaluating their patient's outcomes, interpreting the literature, and counseling their patients preoperatively regarding expectations for improvement. Given that PASS thresholds are fragile and vary greatly depending on cohort variability, caution should be exercised in conflating them across different studies.

BACKGROUND: Superior augment use may help avoid superior tilt while minimizing removal of inferior glenoid bone. Therefore, our goal was to compare superior augments vs. no-augment baseplates in reverse shoulder arthroplasty (RSA) for patients with rotator cuff dysfunction and no significant superior glenoid erosion. METHODS: A multicenter retrospective analysis of 145 patients who underwent RSA with intraoperative navigation (Equinoxe GPS; Exactech) and 3-year follow-up (mean 32 months' follow-up, range 20-61 months) who had preoperative superior inclination less than 10° and retroversion less than 15°. Patient demographics, radiographic measurements, surgical characteristics, patient-reported outcomes at preoperative and postoperative visit closest to 3 years, and adverse events at final follow-up were obtained. Operative time, planned inclination, and planned version of the baseplate were obtained. χ2 test was used to compare categorical variables, and Student t test was used to compare the augment and no-augment cohorts. RESULTS: The study population consisted of 54 superior augment patients and 91 no-augment patients. The augment cohort had lower body mass index (27.2 vs. 29.4, P = .023) and higher native superior inclination (5.9° vs. 1.4°, P < .001). No difference between the augment and no-augment cohorts was found regarding age (P = .643), gender (P = .314), medical comorbidities (P > .05), surgical indication (P = .082), and native glenoid version (P = .564). The augment cohort had higher internal rotation score (4.6 vs. 3.9, P = .023), and all remaining range of motion (ROM) and patient-reported outcomes (PROs) preoperatively were not significantly different. At final follow-up, active ROM in all planes was not different between the cohorts. Regarding PROs, the postoperative Shoulder Arthroplasty Smart score was significantly higher (78.0 vs. 73.6, P = .042), and American Shoulder and Elbow Surgeons Standardized Shoulder Assessment Form score trended toward higher (83.6 vs. 77.5, P = .063) in the augment cohort. The augment cohort had a significantly lower proportion of patients who planned to have superior baseplate tilt (1.9% vs. 14.3%, P = .012) and had greater mean inclination correction (6.3° vs. 1.3°, P < .001), compared with the no-augment cohort. Adverse events were rare, and there was no significant difference found between the augment and no-augment cohorts (5.6% vs. 3.3%, P = .509). DISCUSSION: Superior augmented baseplate in RSA with minimal superior glenoid erosion is associated with similar ROM and adverse events with somewhat improved postoperative PROs compared with nonaugmented baseplates at the 3-year follow-up. Additionally, superior augments resulted in a greater proportion of baseplates planned to avoid superior tilt, and trended toward shorter operative times. Further investigation of long-term glenoid baseplate loosening is imperative to fully understand the cost-effectiveness of superior augments in the setting of minimal glenoid deformity.
RESUMEN
It is important to educate and equip the orthopaedic community with tools to address health care disparities and improve orthopaedic specialty recruitment for racial minorities. How patients and providers are affected by systemic racism in healthcare and what that means in orthopaedic surgery, methods to identify bias and improve access to orthopaedic care for racial minorities, and how to structure a program and department environment to encourage and promote diversity are important topics of discussion.

PURPOSE: To calculate and determine what factors are associated with achieving the Minimal Clinically Important Difference (MCID) and the Substantial Clinical Benefit (SCB) of Patient-Reported Outcomes Measurement Information System (PROMIS) Upper Extremity Computer Adaptive Testing v2.0 (UE), Pain Interference (P-Interference), and Pain Intensity (P-Intensity) in patients undergoing arthroscopic rotator cuff repair (aRCR). METHODS: The change in PROMIS scores representing the optimal cutoff for a ROC curve with an area under the curve analysis was used to calculate the anchor-based MCID and SCB. To assess the responsiveness of each PROM, effect sizes and standardized response means (SRM) were calculated. To identify factors associated with attaining the MCID and SCB, univariate and multivariate logistic regression analyses were performed. RESULTS: A total of 323 patients with an average age of 59.9 ± 9.5 were enrolled in this study, of which, 187/323 [57.9%] were male and 136/323 [42.1%] were female. The anchor-based MCID for PROMIS UE, P-Interference, and P-Intensity was: 9.0, 7.5, and 11.2, respectively. The respective SCB was 10.9, 9.3, and 12.7. Effect size and SRM were: PROMIS UE (1.4, 1.3), P-Interference (1.8, 1.5), and P-Intensity (2.3, 2.0). Lower preoperative P-Intensity scores (p = 0.02), dominant arm involvement (p = 0.03), and concomitant biceps tenodesis (p = 0.03) were associated with patients achieving the SCB for PROMIS UE. CONCLUSION: A large responsiveness for each of the PROMIS instruments due to the majority of patients reporting great improvement after aRCR and a small standard deviation across all outcome measures was shown in our study. Lower preoperative P-Intensity scores and concomitant biceps tenodesis were associated with higher odds of achieving the SCB for PROMIS UE. The knowledge of MCID and SCB values for PROMIS instruments will allow the surgeon to determine whether the improvements in the PROMIS scores after aRCR are clinically meaningful. LEVEL OF EVIDENCE: Level III.

BACKGROUND: Anxiety and depression are the 2 most commonly diagnosed psychiatric disorders in the United States. The effect of these disorders on total shoulder arthroplasty (TSA) outcomes must be appreciated. The purpose of this study was to examine the correlation between a preoperative diagnosis of anxiety and depression and postoperative outcomes after TSA. The secondary goals were to determine whether patients contemporaneously treated with medication for their mental health diagnosis fared better than a cohort treated without medication and to examine the degree to which Patient-Reported Outcomes Measurement Information System Mental Health (PROMIS-MH) scores correlate with patient outcomes. Our hypothesis was that a history of anxiety and/or depression would negatively impact patient outcomes after TSA. METHODS: We performed a retrospective analysis of a prospectively collected cohort at a single institution. Patients undergoing anatomic total shoulder arthroplasty (aTSA) and reverse total shoulder arthroplasty (rTSA) with anxiety and/or depression were identified and compared with a cohort of patients without a mental health diagnosis enrolled in an institutional registry from 2011 to 2020. Demographic characteristics, diagnoses, implant types, range of motion, adverse events, and clinical outcome metric scores-PROMIS-MH score, American Shoulder and Elbow Surgeons score, Constant score, Shoulder Arthroplasty Smart Score-were recorded. Outcomes between cohorts were analyzed using conventional statistics, as well as stratification by the minimal clinically important difference and substantial clinical benefit thresholds where applicable. RESULTS: The study comprised 218 patients (114 rTSA and 95 aTSA patients) with a diagnosis of either anxiety and/or depression and 378 patients (153 rTSA and 217 aTSA patients) with no history. Although both cohorts achieved the minimal clinically important difference and substantial clinical benefit thresholds for the postoperative American Shoulder and Elbow Surgeons score, the cohort with anxiety and/or depression showed lower postoperative outcome scores (P < .05), higher AE rates, and significantly lower preoperative-to-postoperative differences in all variables when compared with the cohort without anxiety and/or depression. There were no differences in outcome scores after rTSA or aTSA between patients being treated for anxiety and/or depression and those not receiving treatment. The PROMIS-MH score was positively correlated with postoperative outcomes and patient satisfaction. CONCLUSION: This study shows that patients with anxiety and/or depression who underwent TSA had inferior postoperative outcomes and higher rates of AEs compared with a cohort without a mental health diagnosis. In addition, patients taking medication for treatment of depression and/or anxiety did not gain any significant benefit in terms of their postoperative shoulder outcomes or satisfaction rate compared with those with this diagnosis but not taking medication. Additionally, we found that, independent of a patient's underlying shoulder pathology or psychiatric diagnosis, lower PROMIS-MH scores were correlated with worse postoperative outcomes.

BACKGROUND: Cervical spine pathology can affect the supporting muscles and function of the shoulder and contribute to shoulder and arm pain and hence may impact postoperative outcomes following shoulder arthroplasty. The purpose of this study was to evaluate the impact of a history of cervical spine arthrodesis and its timing, before or after total shoulder arthroplasty (TSA), on the outcomes of TSA. Our hypothesis is that a history of cervical arthrodesis (CA) will negatively impact patient outcomes after shoulder arthroplasty. METHODS: A retrospective analysis was performed on a prospectively collected cohort at a single institution. Anatomic (aTSA) and reverse TSA (rTSA) patients with CA were identified and compared to a cohort of patients without CA (NCA) enrolled in an institutional registry from 2011 to 2020. Demographic characteristics, diagnoses, implant type, range of motion, adverse events, and clinical outcome metric scores (American Shoulder and Elbow Surgeons Standardized Shoulder Assessment Form [ASES], Constant, Shoulder Function score, patient satisfaction) were recorded. Outcomes between cohorts were analyzed using conventional statistics as well as stratification by minimal clinically important difference and substantial clinical benefit (SCB) thresholds where applicable. RESULTS: Of the 573 TSAs evaluated, 48 (20a CA-aTSA and 28 CA-rTSA) had a history of CA and 525 (280 NCA-aTSA and 245 NCA-rTSA) had no history of CA. The CA-TSA (aTSA and rTSA) had lower Constant, ASES, and Shoulder Function scores postoperatively as well as less improvement in active external rotation and an overall lower satisfaction rating (P < .05 for all) compared with NCA-TSA. The adverse event rate in the CA-TSA cohort was higher compared with the NCA-TSA cohort (25% vs. 6.5% [rTSA; P = .004] and 24.5% vs. 11% [aTSA; P = .068]). Optimal cutoff analysis showed that a time from CA to TSA of greater than 1.33 years had a sensitivity of 75.0% and specificity of 75.0% in predicting achievement of SCB for ASES score. CONCLUSION: The current study demonstrates that patients with a history of CA undergoing shoulder arthroplasty results in lower postoperative functional outcomes, lower satisfaction, and higher rates of postoperative adverse events requiring surgical revision when compared to a cohort without a history of CA. Additionally, the current study demonstrates that a time interval of at least 16 months between CA and shoulder arthroplasty optimizes the chances of achieving SCB for ASES score.

BACKGROUND: The purpose of this study was to compare clinical, implant-related, and patient-reported outcomes of shoulders undergoing conversion to reverse total shoulder arthroplasty (rTSA) following previous open reduction-internal fixation vs. shoulders undergoing rTSA as a primary treatment modality for acute proximal humeral fractures (PHFs) in patients aged ≥65 years. METHODS: We performed a retrospective analysis of a prospectively collected cohort of patients who underwent primary rTSA for PHFs vs. a cohort who underwent conversion arthroplasty with rTSA following fracture repair between 2009 and 2020. Outcomes were assessed preoperatively and at latest follow-up. Demographic characteristics and outcomes were analyzed between cohorts using conventional statistics, as well as stratification by minimal clinically important difference and substantial clinical benefit thresholds where applicable. RESULTS: In total, 406 patients met the study criteria, of whom 322 underwent primary rTSA for PHF and 84 underwent conversion rTSA after failed PHF open reduction-internal fixation. The conversion rTSA cohort was, on average, 7 years younger than the primary rTSA cohort (65 ± 10 years vs. 72 ± 9 years, P < .001). The follow-up periods were similar between the cohorts, with an average of 47.1 months (range, 24-138 months). The percentages of Neer 3-part (41.9% vs. 45.2%) and 4-part (49.1% vs. 46.4%) PHFs were similar (P > .99). The primary rTSA cohort achieved higher forward elevation, external rotation, and patient-reported outcome measurements including Simple Shoulder Test, American Shoulder and Elbow Surgeons, University of California-Los Angeles, Constant, Shoulder Arthroplasty Smart, and Shoulder Pain and Disability Index scores at a minimum of 24 months postoperatively (P < .05 for all). Patient satisfaction was higher in the primary rTSA group than in the conversion rTSA cohort (P = .002). Patient-reported outcome measures uniformly favored the primary rTSA cohort, rising to the level of statistical significance for forward elevation, American Shoulder and Elbow Surgeons score, and Shoulder Pain and Disability Index score (P < .05) relative to substantial clinical benefit. The adverse event rate and revision rate in the conversion rTSA cohort were higher than those in the primary rTSA cohort (26.2% vs. 2.5% [P < .001] and 8.3% vs. 1.6% [P = .001], respectively). At 10 years postoperatively, the revision-free implant survival rate was significantly lower in the conversion cohort compared with the primary cohort (66% vs. 94%, P = .012). Finally, the hazard ratio of revision was 3.69 in the conversion rTSA cohort compared with only 1.0 in the primary rTSA cohort. CONCLUSION: This study demonstrates that elderly patients who undergo rTSA as a conversion procedure following previous osteosynthesis do not fare as well as those treated with rTSA for acute displaced PHFs. Conversion rTSA patients report lower patient satisfaction and have significantly restricted range of shoulder motion, a higher risk of complications, a higher risk of revision, poorer patient-reported outcomes, and a shorter implant survival rate at 10 years compared with patients undergoing acute rTSA.

BACKGROUND: The purpose of this study was to implement a modified Delphi technique among a group of experts affiliated with American Shoulder and Elbow Surgeons (ASES) and European Society for Surgery of the Shoulder and Elbow (SECEC) to determine areas of consensus regarding what factors influence their decision to manage a patient surgically and what specific treatment modalities they utilize for patients ≤50 years of age with glenohumeral arthritis. METHODS: The panel of experts comprised 168 shoulder and elbow specialists, 138 ASES and 30 SECEC members. In the first round, an open-ended questionnaire was utilized to solicit features that are important in making decisions regarding treatment. The second round involved ranking the features identified in the first round as to their importance in helping decision making for surgery. The results of round 2 were then utilized and 18 complex surgical cases previously treated by one of the lead authors were provided for the study. One additional case was included to address the management of Cutibacterium acne infection. RESULTS: A total of 159 (95.0%) participants completed the round one survey, 142 (89%) responded to the second and third round surveys. In total 50 individual factors were positively associated with the decision to proceed with surgery. Ten of these were strongly supportive of surgery. Eight out of 18 clinical cases demonstrated > 80% agreement on the surgical treatment modality chosen. Over 90% of respondents chose reverse total shoulder arthroplasty (TSA) to manage pathology when an incompetent rotator cuff was present. Over 90% of respondents managed avascular necrosis with hemiarthroplasty. Over 70% of respondents chose anatomic TSA for inflammatory arthritis with low demand on their shoulder. Overall, 79% of respondents chose a stemless humeral component when a hemiarthroplasty or anatomic TSA was chosen in response to the proposed surgical cases. If arthroscopy was chosen then there was good agreement on 5 core procedures. There was only fair consensus on the approach to C. acnes in patients with glenohumeral osteoarthritis ≤ 50 years of age. CONCLUSION: The optimal treatment of glenohumeral arthritis in patients ≤ 50 years of age remains controversial, and there are many treatment options to consider when responding to the variety of clinical presentations and anatomic pathologies. While physicians and patients engage in the shared decision-making process regarding the final choice for management, this consensus statement serves as a basis for discussion amongst colleagues and between patients and surgeons though it clearly demonstrates that the topic must be further investigated prospectively and with large cohorts.

BACKGROUND: Identifying risk factors for acromial and scapular fractures improves our understanding about which variables are relevant to these fracture complications; however, these data are difficult to integrate into clinical practice because the majority of reverse total shoulder arthroplasty (rTSA) patients have ≥1 risk factor. The goal of this study was to better facilitate preoperative identification of patients at risk of acromial and scapular fractures and quantify the impact of accumulating risk factors on the incidence of fracture. METHODS: We retrospectively analyzed 9079 rTSA patients from a multicenter database of rTSA procedures performed with a single medialized glenoid-lateralized humerus onlay rTSA prosthesis to quantify the rate of acromial and scapular fractures. Univariate and multivariate analyses were performed to identify risk factors for fracture. Next, we quantified the number of patients with 1 or multiple significant risk factors for fracture. Finally, to facilitate preoperative identification of patients most at risk of fracture, we stratified our data set using multiple combinations of age, sex, and diagnosis risk factors and calculated the odds ratio for each cohort to quantify the impact of accumulating risk factors on the incidence of fracture. RESULTS: A fracture of the acromion or scapula was radiographically identified in 138 of 9079 patients, for a rate of 1.52%. Patients with fractures were more likely to be older, of female sex, to have a diagnosis of rheumatoid arthritis and/or cuff tear arthropathy, and were less likely to have a diagnosis of diabetes. Eighty-five percent of rTSA patients had ≥1 fracture risk factor. Individually, age, sex, or diagnosis failed to identify any patient cohort with an odds ratio >2.5. Use of multiple combinations of patient risk factors refined the identification of at-risk patients better than any individual risk factor or 2-risk factor combination and demonstrated that the patients with the greatest fracture risk were female patients with a rheumatoid arthritis diagnosis who were aged >70, >75, and >80 years. CONCLUSION: This 9079-rTSA multicenter study demonstrated that 1.52% of patients experienced acromial and/or scapular fractures with a single medialized glenoid-lateralized humerus onlay rTSA prosthesis. Our analysis identified numerous risk factors and quantified the impact of accumulating risk factors on fracture incidence. Patients who are considering rTSA and who have these age, sex, and diagnosis risk factors should be made aware of their elevated complication risk.

BACKGROUND: The goal of this longitudinal analysis of anatomic total shoulder arthroplasty (aTSA) and reverse total shoulder arthroplasty (rTSA) utilization from 2007 to 2021 is to quantify changes in clinical outcomes, cost, and value, resulting from the introduction and adoption of new shoulder arthroplasty (SA) technologies. METHODS: We analyzed an international database of a single SA prosthesis (Equinoxe; Exactech, Inc.; Gainesville, FL, USA) for all clinical sites that have continuously enrolled cases from 2007 to 2021 to compare changes in primary aTSA and primary rTSA utilization and outcomes across 3, 5-year cohorts based upon the date of implantation. A value analysis was conducted across the 5-year implantation cohorts, with value measured by the ratio of each postoperative outcome measure at 24-36 months and 36-60 months after surgery, and the average implant selling price each year for the U.S. sites in constant 2007 U.S. dollars. These measures of value were compared between cohorts to quantify the impact of new technology introduced over the study period. RESULTS: A dramatic increase in rTSA utilization was observed across the 6 sites over the 15-year study period, along with a rapid adoption of new aTSA and rTSA technologies. The average patient receiving primary aTSA and primary rTSA changed over the 15-year study period, with significant shifts in diagnosis, comorbidities, and preoperative functional status. A comparison of postoperative results demonstrated that both aTSA and rTSA clinical and radiographic outcomes showed improvement relative to 2007-2011. Over this 15-year study period, the average aTSA implant selling price has been relatively stable while the average rTSA implant selling price has significantly declined. As a result, the value associated with the Equinoxe rTSA significantly increased for nearly every outcome measure at 24-36 months and 36-60 months after surgery, while value associated with the Equinoxe aTSA stayed relatively constant from 2007 to 2021. CONCLUSION: Our 6042-patient longitudinal analysis quantified numerous changes in utilization, outcomes, and value across 6 clinical sites over the 15-year study period. Rapid adoption of new aTSA and rTSA technologies was observed and clinical and radiographic outcomes improved relative to 2007-2011. These clinical improvements, in combination with steady aTSA and declining rTSA implant prices, have driven rTSA value to continuously increase while aTSA value has been maintained at a high-level over the 15-year study period with this particular SA system, even when considering the cost and adoption of new technologies.

BACKGROUND: Preoperative planning software with intraoperative guidance technology is increasingly being used to manage complex glenoid deformity in anatomic total shoulder arthroplasty (TSA) and reverse TSA. The aim of this study was to review the intraoperative efficacy and complications of computer-assisted navigation (CAN) surgery for the treatment of glenoid deformity in TSA. METHODS: We performed a retrospective review of all TSAs implanted using a single computer navigation shoulder system. All patients underwent preoperative planning with computed tomography-based preoperative planning software. The starting point on the glenoid and the final version and inclination of the central post (cage) of the glenoid component were reviewed on the intraoperative navigation guidance report and compared with these parameters on the preoperative plan for each patient. The intraoperative accuracy of CAN for glenoid positioning was determined by the deviation of the starting point and final position of the central cage drill in the glenoid compared with the preoperative plan. Data regarding intraoperative complications and the number of times the navigation system was abandoned intraoperatively were collected. RESULTS: A total of 16,723 anatomic TSAs and reverse TSAs performed worldwide with the aforementioned navigation system were included in this review. In 16,368 cases (98%), every step of the navigation procedure was completed without abandoning use of the system intraoperatively. There was minimal deviation in the intraoperative execution of the preoperative plan with respect to version (0.6° ± 1.96°), inclination (0.2° ± 2.04°), and the starting point on the glenoid face (1.90 ± 1.2 mm). In this cohort, 9 coracoid fractures (0.05%) were reported. CONCLUSION AND DISCUSSION: This study demonstrates the safety and efficacy of CAN for glenoid implantation in TSA. Future studies should focus on assessing the impact of CAN on the longevity and survival of glenoid components and improving the cost-effectiveness of this technology.

BACKGROUND: Primary idiopathic adhesive capsulitis (AC) is characterized by shoulder pain and global limitations in range of motion (ROM). The aim of this study was to determine (1) if a spectrum of symptom severity exists during the freezing phase of AC and (2) identify factors associated with patient selection of corticosteroid injection (CSI) for treatment. METHODS: Patients presenting within 6 months of symptom onset of AC (freezing phase) were enrolled in this single-site retrospective case control study. Visual analog pain scale (VAS) score, shoulder ROM, American Shoulder and Elbow Surgeons Standardized Shoulder Assessment Form (ASES) scores, and Patient-Reported Outcomes Measurement Information System (PROMIS function and pain) scores were collected. Each patient was offered oral anti-inflammatory medication, physical therapy, and intra-articular CSI. Patients were divided into 2 cohorts: those electing vs. those deferring CSI. Multivariable logistic regression was performed to identify patient or symptom characteristics predictive of electing CSI. RESULTS: A total of 112 patients (mean age = 54.7 ± 8.8 years, female = 76 [67.9%], mean symptom duration = 13.2 ± 7.9 weeks, elected CSI = 74 [66.1%]) were included in our analysis. The overall study population demonstrated a wide spectrum of VAS pain scores (6.0 ± 2.8, range: 0-10) and ROM: forward elevation (99° ± 27°, range: 30°-150°), abduction (82° ± 24°, range: 30°-130°), external rotation (47° ± 13°, range: 0°-90°), internal rotation (38° ± 26°, range: 5°-90°). The CSI group had higher mean VAS pain score (6.6 ± 2.5 vs. 4.9 ± 3.0, P = .005) and greater limitations in ROM for forward elevation (92° ± 27° vs. 113° ± 25°, P = .001) and abduction (77° ± 24° vs. 90° ± 21°, P = .005) compared with the non-CSI cohort. The CSI group demonstrated significantly worse shoulder function based on Constant (P < .05), ASES (P = .001), P-UE (P = .016), P-Intensity (P = .002), and P-Interference (P = .004). Logistic regression demonstrated decreased total shoulder ROM in forward elevation and abduction plane (OR = 0.98, 95% CI = 0.97-0.99, P = .004). Hispanic ethnicity and increased VAS pain score (OR = 1.20, 95% CI = 1.01-1.43, P = .04) were associated with increased likelihood of electing CSI. CONCLUSION: A spectrum of symptom severity exists during the freezing phase of primary AC, despite similar etiology. AC patients with greater pain severity, and greater limitations in ROM at initial evaluation were associated with patient selection of CSI.

BACKGROUND: Early reverse total shoulder arthroplasty (rTSA) designs had high failure rates, mainly from loosening of the glenoid baseplate. The purpose of this study was to determine the incidence of aseptic glenoid baseplate loosening after primary rTSA using a contemporary medialized glenoid-lateralized humerus system and identify significant risk factors associated with loosening. METHODS: A total of 7162 patients underwent primary rTSA with a single-platform rTSA system between April 2007 and August 2021; of these primary rTSA patients, 3127 with a minimum 2-year follow-up period were identified. Patients with aseptic glenoid baseplate loosening were compared with all other primary rTSA patients without loosening. Univariate and multivariate analyses were performed to compare these cohorts and identify the demographic characteristics, comorbidities, operative parameters, and implant characteristics associated aseptic glenoid loosening after rTSA. Odds ratios (ORs) were calculated for each significant risk factor and for multiple combinations of risk factors. RESULTS: Irrespective of minimum follow-up, 53 of 7162 primary rTSA shoulders (31 female and 22 male shoulders) experienced aseptic glenoid loosening, for an overall rate of 0.74%. At latest (2-year minimum) follow-up, 30 of 3127 patients experienced aseptic glenoid loosening and showed significantly lower clinical scores, function, and active range of motion and higher pain scores than patients without loosening. Univariate analysis identified rheumatoid arthritis (P = .029; OR, 2.74) and diabetes (P = .028; OR, 1.84) as significant risk factors for aseptic glenoid loosening after rTSA, and multivariate analysis identified Walch glenoid types B2 (P = .002; OR, 4.513) and B3 (P = .002; OR, 14.804), use of expanded lateralized glenospheres (P = .025; OR, 2.57), and use of augmented baseplates (P = .001; OR, 2.50) as significant risk factors. CONCLUSION: The incidence of aseptic glenoid baseplate loosening was 0.74% for the evaluated medialized glenoid-lateralized humerus rTSA system. Numerous risk factors for aseptic loosening were identified, including rheumatoid arthritis, diabetes, Walch type B2 and B3 glenoids, posteriorly-superiorly augmented baseplates, and expanded lateralized glenospheres. Finally, analysis of multiple combinations of risk factors identified patients and implant configurations with the greatest risk of aseptic glenoid loosening.

BACKGROUND: Parkinson disease (PD) is an established risk factor for higher rates of complications and revision surgery following shoulder arthroplasty, yet the economic burden of PD remains to be elucidated. The purpose of this study is to compare rates of complication and revisions as well as inpatient charges for shoulder arthroplasty procedures between PD and non-PD patients using an all-payer statewide database. METHODS: Patients undergoing primary shoulder arthroplasty from 2010 to 2020 were identified from the New York (NY) Statewide Planning and Research Cooperative System (SPARCS) database. Study groups were assigned based on concomitant diagnosis of PD at the time of index procedure. Baseline demographics, inpatient data, and medical comorbidities were collected. Primary outcomes measured were accommodation, ancillary, and total inpatient charges. Secondary outcomes included postoperative complication and reoperation rates. Logistic regression was performed to evaluate effect of PD on shoulder arthroplasty revision and complication rates. All statistical analysis was performed using R. RESULTS: A total of 39,011 patients (429 PD vs. 38,582 non-PD) underwent 43,432 primary shoulder arthroplasties (477 PD vs. 42,955 non-PD) with mean follow-up duration of 2.9 ± 2.8 years. The PD cohort was older (72.3 ± 8.0 vs. 68.6 ± 10.4 years, P < .001), with greater male composition (50.8% vs. 43.0%, P = .001), and higher mean Elixhauser scores (1.0 ± 4.6 vs. 7.2 ± 4.3, P < .001). The PD cohort had significantly greater accommodation charges ($10,967 vs. $7,661, P < .001) and total inpatient charges ($62,000 vs. $56,000, P < .001). PD patients had significantly higher rates of revision surgery (7.7% vs. 4.2%, P = .002) and complications (14.1% vs. 10.5%, P = .040), as well as significantly higher incidences of readmission at 3 and 12 months postoperatively. After controlling for age and baseline comorbidities, PD patients had 1.64 times greater odds of reoperation compared to non-PD patients (95% CI 1.10, 2.37; P = .012) and a hazard ratio of 1.54 for reoperation when evaluating revision-free survival following primary shoulder arthroplasty (95% CI 1.07, 2.20; P = .019). CONCLUSIONS: PD confers a longer length of stay, higher rates of postoperative complications and revisions, and greater inpatient charges in patients undergoing TSA. Knowledge of the associated risks and resource requirements of this population will aid surgeons in their decision making as they continue to provide care to a growing number of patients affected by PD.

PURPOSE: The purpose of this study was to compare the outcomes of primary reverse total shoulder arthroplasty (rTSA) using glenoid bone grafting (BG rTSA) with primary rTSA using augmented glenoid baseplates (Aug rTSA) with a minimum 2-year follow-up. METHODS: A total of 520 primary rTSA patients treated with 8° posterior glenoid augments (n = 246), 10° superior glenoid augments (n = 97), or combined 10° superior/8° posterior glenoid augments (n = 177) were compared with 47 patients undergoing glenoid bone grafting for glenoid bone insufficiency. The mean follow-up was 37.0(±16) and 53.0(±27) months, respectively. Outcomes were analyzed preoperatively and at the latest follow-up using conventional statistics and stratification by minimum clinically important difference (MCID) and substantial clinical benefit (SCB) thresholds where applicable. Radiographs were analyzed for baseplate failure, and the incidences of postoperative complications and revisions were recorded. RESULTS: The glenoid Aug rTSA cohort had greater improvements in patient-reported outcome measures (PROMs) and range of motion when compared with the BG rTSA group at a minimum of 2-year follow-up, including Simple Shoulder Test, Constant score, American Shoulder and Elbow Surgeons score, University of California Los Angeles score, Shoulder Pain and Disability Index score, shoulder function, Shoulder Arthroplasty Smart score, abduction, and external rotation (P < .05). Patient satisfaction was higher in the Aug rTSA group compared with the BG rTSA group (P = .006). The utilization of an augmented glenoid component instead of glenoid bone grafting resulted in approximately 50% less total intraoperative time (P < .001), nearly 33% less intraoperative blood loss volume (P < .001), approximately 3-fold less scapular notching (P < .01), and approximately 8-fold less adverse events requiring revision (P < .01) when compared with the BG rTSA cohort. Aside from SCB for abduction, the Aug rTSA cohort achieved higher rates of exceeding MCID and SCB for every PROM compared with BG rTSA. More specifically, 77.6% and 70.2% of the Aug rTSA achieved SCB for American Shoulder and Elbow Surgeons and Shoulder Pain and Disability Index vs. 55% and 48.6% in the BG rTSA, respectively (P = .003 and P = .013). CONCLUSION: The present midterm clinical and radiographic study demonstrates that the utilization of an augmented baseplate for insufficient glenoid bone stock is superior as judged by multiple PROMs and range of motion metrics when compared with bone graft augmentation at minimum 2-year follow-up. In addition, when analyzed according to MCID and SCB thresholds, the use of augmented baseplates outperforms the use of glenoid bone grafting. Complication and revision rates also favor the use of augmented glenoid baseplates over glenoid bone grafting. Long-term clinical and radiographic follow-up is necessary to confirm that these promising midterm results are durable.
