The Patient-Reported Outcomes Measurement Information System Upper Extremity Computer Adaptive Test (PROMIS UE CAT) is a newer patient-reported outcome measure for upper extremity physical function. To date, no longitudinal study exists assessing PROMIS UE CAT responsiveness in patients undergoing shoulder arthroplasty. The purpose of this prospective longitudinal study is to report PROMIS UE CAT responsiveness to change and correlation to legacy instruments in patients undergoing total shoulder arthroplasty (TSA). Ninety-six patients (97 shoulders) undergoing TSA completed the PROMIS UE, Oxford Shoulder Score (OSS), American Shoulder and Elbow Surgeons (ASES), and Simple Shoulder Test (SST) preoperatively and postoperatively at 6 weeks, 12 weeks, and after 6 months. Spearman's correlation coefficients (r) were calculated between PROMIS UE and other scores at each time-point. Responsiveness to change was assessed using the effect size (Cohen's d) and standardized response mean compared with the preoperative time-point. Floor and ceiling effects were also assessed. PROMIS UE CAT demonstrated positive responsiveness at all time-points after TSA. It demonstrated excellent correlation (range: 0.68-0.84) with ASES, SST, and OSS at all postoperative time-points, but the correlation was weaker (r < 0.6, except OSS) preoperatively. Only OSS and SST showed ceiling effects at the 6-12-month time-point (16.8% and 18.2%, respectively). PROMIS UE CAT responsiveness to change and strength of correlation with legacy instruments improves with time elapsed after TSA. Further quantification of meaningful responsiveness to change will require estimation of the minimal clinically important difference and substantial clinical benefit for PROMIS UE CAT.

Background/UNASSIGNED:The Patient-Reported Outcomes Measurement Information System minimal clinically important difference (PROMIS MCID), substantial clinical benefit (SCB), and patient acceptable symptom state (PASS) of patient-reported outcome measures provide clinical significance to patient-reported outcome measures scores. The goal of this study is to measure the MCID, SCB, and PASS of PROMIS Upper Extremity v2.0 (PROMIS UE) in patients undergoing total shoulder arthroplasty (TSA). Methods/UNASSIGNED:All patients who underwent TSA since October 2017 were identified from our institutional database. Patients who had completed the PROMIS UE outcome measure before surgery were asked to complete a PROMIS UE and anchor survey that contained two transition questions to assess patient satisfaction and change in symptoms since treatment. The anchor-based MCID, SCB, and PASS were calculated as the change in PROMIS UE score that represented the optimal cutoff for a receiver operating characteristic curve. The distribution-based MCID was calculated as a range between the average standard error of measurement multiplied by 2 different constants: 1 and 2.77. Results/UNASSIGNED:This study enrolled 165 patients. The anchor-based MCID for PROMIS UE was calculated to be 8.05 with an AUC of 0.814. The anchor-based SCB was calculated to be 10.0 with an AUC of 0.727. The distribution-based MCID was calculated to be between 3.12 and 8.65. The PASS was calculated to be 37.2 with an AUC of 0.90. Conclusions/UNASSIGNED:The establishment of MCID, SCB, and PASS for PROMIS UE scores after shoulder arthroplasty provides meaningful and objective clinical interpretation of the improvements in outcome scores after TSA.

Background: The purpose of this study was to determine if addition of CT to axillary radiographs (AXR) alters preoperative decision making for shoulder arthroplasty. Methods: Preoperative deidentified images (XR alone and XR with CT) of 50 patients with glenohumeral arthritis were reviewed independently by 3 reviewers in a blinded fashion. Each reviewer graded images for glenoid wear pattern as simple (Walch A1 or B1) or advanced [A2, B2, C]), adequacy of AXR and need for advanced imaging. The reviewers determined a preoperative plan for all patients based on XR alone vs. XR and CT including the arthroplasty type (anatomic or reverse total shoulder) and their plan for treating glenoid wear (eccentric or standard reaming vs. bone graft or augment). Kappa values (κ) were calculated to determine inter-rater agreement and consistency among multiple reviewers. Fisher's exact test was used to assess any difference in preoperative plan once the shoulders were separated into simple and advanced glenoid wear patterns. Results: The 3 reviewers agreed that quality of AXRs was significantly inadequate (P <.001) for assessing glenoid wear in advanced glenoid wear patterns compared to simple wear patterns. Following evaluation on AXRs alone, the need for CT imaging was significantly higher in advanced glenoid wear patterns compare to simple ones (81% vs. 31%; P <.001). The addition of CT images did not result in a significant change to the preoperative plan in simple glenoid wear patterns but in advanced glenoid wear, addition of CT can change the preoperative plan with respect to arthroplasty type and/or strategy for addressing glenoid wear. Conclusion: Axillary radiographs are often inadequate for preoperative planning in shoulder arthritis with advanced glenoid wear patterns (Walch A2, B2, C types). Addition of CT imaging to radiographs in shoulder arthritis with advanced glenoid wear can affect the preoperative decision with respect to type of shoulder arthroplasty and/or plan for addressing glenoid wear (reaming, bone graft or augmented glenoids). Level of evidence: Level IV

BACKGROUND:The objective of this study is to assess patient satisfaction and preference for telemedicine- versus in-person visits for outpatient shoulder and elbow musculoskeletal consultation during the COVID-19 pandemic and in the future. METHODS:Patients who had telemedicine visits for shoulder and elbow musculoskeletal complaints at a single institution from March through June, 2020, were invited to respond to a post-visit survey. The survey included a standardized questionnaire that focused on the patient's satisfaction with the telemedicine visit(s) during the pandemic and preference for using the telemedicine platform in the future following the pandemic. Additional details regarding their virtual visits (severity of their medical condition, previous virtual- or ER visits) were also obtained. Data regarding patient demographics and visit details (primary diagnosis, type of visit, length of visit, treating physician) were extracted from electronic medical records. RESULTS:In total, 153 patients participated in the study. Overall, high satisfaction scores regarding the telemedicine visit were noted: 91% of patients reported that their concerns were adequately addressed, 89% would recommend telemedicine to a friend and 94% stated that they would use this platform again in the presence of a situation like the COVID-19 pandemic. However, the majority of patients (76%) reported a preference for in-person visits for the same musculoskeletal complaint if it were not for COVID-19. A telemedicine visit duration of more than 10 minutes and a first-time telemedicine visit correlated with higher satisfaction rates (P=0.037 and P=0.001, respectively). CONCLUSIONS:COVID-19 has provided a boost to the use of our telemedicine platform, with a high satisfaction rate among patients with shoulder and elbow musculoskeletal complaints, largely due to safety reasons and limited access to in-person doctor visits. However, a considerable number of patients would have preferred in-person visits for similar health complaints if there were no pandemic. Further research on optimizing the selection of patients for telemedicine visits and addressing their expectations and concerns regarding their visits will improve patients' preference for future telemedicine visits.

PURPOSE/OBJECTIVE:To correlate the Patient Reported Outcomes Measurement Information System Upper Extremity (PROMIS UE) score with preexisting validated outcomes scores, American Shoulder and Elbow Surgeons score (ASES), and Constant score (CS) in patients with idiopathic adhesive capsulitis (AC). METHODS:Patients with a clinical diagnosis of idiopathic AC ("freezing" or "frozen" phases) who agreed to complete the ASES, CS, and PROMIS UE scores during their office visit were included in this study. Trained researchers performed the objective clinical assessments on the included patients. Responses to the 3 outcomes scores were statistically analyzed and compared utilizing Pearson correlation coefficients. Floor and ceiling effects were calculated. RESULTS:The final cohort included 100 patients with AC of which there were 72% female and 87% right hand dominant, with a mean age of 55 years. The PROMIS UE required fewer question responses (5.02 ±1.84) compared to the fixed questions burden with ASES (12) and CS (9). The mean outcome scores were 34.6 ± 2.5 (PROMIS UE), 55 ± 22 (ASES), and 51 ± 16 (CS). The PROMIS UE displayed excellent correlation with both the ASES (r = 0.80, 95% [CI: 0.72, 0.86], p < 0.001) and CS (r = 0.76, 95% CI [0.67, 0.83], p < 0.001). Neither ceiling nor floor effects were present. CONCLUSION/CONCLUSIONS:The PROMIS UE displayed comparable efficacy to commonly used legacy outcome scores (ASES and CS) in adhesive capsulitis. A lower question burden with the PROMIS UE carries a potential for wider acceptibility with the researchers and patients with shoulder pathology.

Traditionally, total shoulder arthroplasty is performed through the deltopectoral approach with violation of the subscapularis tendon. In order to reduce the incidence of postoperative subscapularis dysfunction, the subscapularis-sparing approach, performed entirely through the rotator interval, was developed. This technique allows earlier rehabilitation and may potentially prevent subsequent subscapularis insufficiency and clinical failures.

Background: Pectoralis major ruptures are increasing in incidence primarily due to an increase in awareness, activity level among young males between 20 - 40 years of age, and use of anabolic steroids. Although the majority of pectoralis major ruptures are acute injuries, many chronic ruptures are unrecognized and it is imperative to understand proper evaluation of these injuries, as well as the appropriate treatment for acute and chronic ruptures. Purpose: Pectoralis major ruptures can lead to deformity and physical disability if left untreated. This review paper discusses the both acute and chronic ruptures as well as indications for nonoperative treatment and operative treatment to give the reader the best understanding of this diagnosis and proper management. Methods: A systematic review of the literature was performed using a search of electronic databases. Search terms such as pectoralis major rupture, pectoralis major repair, pectoralis major tendon transfer and pectoralis major nonoperative treatment were used. Case reports, systematic reviews, prospective and retrospective studies were included to provide a comprehensive review. The only exclusion criteria consisted of studies not published in English. This review article includes the anatomy and biomechanics of the pectoralis major muscle, proper evaluation of the patient, operative and nonoperative treatment of acute and chronic pectoralis major ruptures, and outcomes of the recommended treatment. Conclusion: Nonoperative treatment is indicated for patients with medical comorbidities, older age, incomplete tears, or irreparable damage. Patients treated non-operatively have been shown to lose strength, but regain full range of motion. Patients with surgery before 6 weeks reported better outcomes than patients with surgery between 6-8 weeks. The chronicity of the rupture (>8 weeks) increases likelihood of reconstruction, involving the use of autografts or allografts. Patients treated with delayed repair had significantly better strength, satisfaction and outcomes than patients with nonoperative treatment. The pectoralis tendon can also be transferred in patients with rotators cuff tears, atrophy, or significant functional limitation. Tendon transfers have been shown to have unpredictable outcomes, but overall satisfactory results.

Although total shoulder arthroplasty (TSA) is generally associated with good to excellent outcomes in most patients, the integrity and function of the subscapularis tendon (SSC) is of paramount importance because SSC rupture after TSA can lead to inferior outcomes. Therefore, the efficacy of a SSC-sparing TSA procedure was evaluated through a prospective, double-blinded, randomized study. Patients with end-stage osteoarthritis of the shoulder were randomized into 2 groups. Group 1 patients were treated with TSA in which the prosthesis was inserted entirely through the rotator interval without violating the SSC tendon (SPARING). Group 2 patients were treated with TSA using the SSC tenotomy approach (STANDARD). Both the patients and the evaluators remained blinded to the surgical approach throughout the study. Outcome data collected included the visual analog scale score for pain and the American Shoulder and Elbow Surgeons outcome score. Complete 2-year outcome data were collected from 32 SPARING and 38 STANDARD patients at a mean follow-up of 31.1 and 33.4 months, respectively. The American Shoulder and Elbow Surgeons and visual analog scale scores improved significantly for both groups. Differences between groups did not reach statistical significance. Complication profiles were similar for the 2 groups, with 3 patients in the SPARING group and 2 patients in the STANDARD group requiring revision surgery during the study. At short-term follow-up, the outcome of TSA using the SSC-sparing surgical approach was similar to the outcome of TSA using the standard approach. Studies with longer follow-up are required to document the potential benefits of this surgical technique. [Orthopedics. 2019; 42(1):e61-e67.].

AIMS/OBJECTIVE:The aim of this study was to investigate the effects of preoperative bisphosphonate treatment on the intra- and postoperative outcomes of arthroplasty of the shoulder. The hypothesis was that previous bisphosphonate treatment would adversely affect both intra- and postoperative outcomes. PATIENTS AND METHODS/METHODS:group, there were 52 female and six male patients, with a mean age of 72.1 years (53 to 88). RESULTS:Previous treatment with bisphosphonates was positively associated with intraoperative complications (fracture; odds ratio (OR) 39.40, 95% confidence interval (CI) 2.42 to 6305.70) and one-year postoperative complications (OR 7.83, 95% CI 1.11 to 128.82), but did not achieve statistical significance for complications two years postoperatively (OR 3.45, 95% CI 0.65 to 25.28). The power was 63% for complications at one year. CONCLUSION/CONCLUSIONS:Patients who are treated with bisphosphonates during the three-year period before shoulder arthroplasty have a greater risk of intraoperative and one-year postoperative complications compared with those without this previous treatment.
