Subscapularis Management in Anatomic Total Shoulder Arthroplasty A Review.

Surgical management of the subscapularis tendon is critical to a successful outcome following anatomic total shoulder arthroplasty. However, the optimal surgical technique for adequate exposure of the glenohumeral joint while mini-mizing complications resulting from subscapularis tendon dysfunction continues to be controversial. Common surgical techniques for the management of the subscapularis tendon include tenotomy, peeling, sparing, and lesser tuberosity oste-otomy. Despite a number of published studies comparing these techniques, no consensus has been reached regarding optimal management. This article reviews the extensive literature on the biomechanical, radiologic, and clinical outcomes of each technique, including recently published comparison studies.

Factors affecting operating room scheduling accuracy for primary and revision total hip arthroplasty: a retrospective study.

INTRODUCTION: Optimizing operating room (OR) scheduling accuracy is important for OR efficiency, meeting patient expectations, and maximizing value for health systems. However, limited data exist on factors influencing the precision of Total Hip Arthroplasty (THA) OR scheduling. This study aims to identify the factors influencing the accuracy of OR scheduling for THA. METHODS: A retrospective review of 6,072 THA (5,579 primary THA and 493 revision THA) performed between January 2020 and May 2023 at an urban, academic institution was conducted. We collected baseline patient characteristics, surgeon years of experience, and compared actual wheels in to wheels out (WIWO) OR time against scheduled OR time. Significant scheduling inaccuracies were defined as actual OR times deviating by at least 15% from scheduled OR times. Logistic regression analyses were employed to assess the impact of patient, surgeon, and intraoperative factors on OR scheduling accuracy. RESULTS: Using adjusted odds ratios, primary THA patients who had a lower BMI and surgeons who had less than 10 years of experience were associated with overestimation of OR time. Whereas, higher BMI, younger age, general anesthesia, non-primary osteoarthritis indications, and afternoon procedure start times were linked to underestimation of OR time. For revision THA, lower BMI and fewer components revised correlated with overestimated OR time. Men, higher BMI, more components revised, septic indication for surgery, and morning procedure start times were associated with underestimation of OR time. CONCLUSION: This study highlights several critical patient, surgeon, and intraoperative factors influencing OR scheduling accuracy for THA. OR scheduling models should consider these factors to enhance OR efficiency.

Calibration of magnification in two-dimensional low-dose full-body imaging for preoperative planning of total hip arthroplasty.

INTRODUCTION: Preoperative planning of total hip arthroplasty (THA) using two-dimensional low-dose (2DLD) full-body imaging has gained popularity in recent years. The low-dose imaging system is said to produce a calibrated image with constant 1:1 magnification. However, the planning software used in conjunction with those images may introduce variations in the degree of magnification in 2DLD imaging, and this has not yet been investigated. The purpose of the present study was to quantify any variation in 2DLD image to assess the need for image calibration when using conventional planning software. METHODS: Postoperative 2DLD images from 137 patients were retrospectively evaluated. Only patients who underwent THA for primary osteoarthritis were included in the study cohort. The femoral head diameter was measured by two independent observers using both Orthoview™ and TraumaCad™ planning software programs. Actual sizes of the femoral head implants were extracted from surgical reports to calculate image magnification. Magnification measurement reliability was calculated with the intra-class correlation coefficient (ICC) index. RESULTS: Image magnification varied among cases (mean 133%, range 129-135%). There was no statistical difference in mean image magnification among the various implant sizes (p = 0.8). Mean observer and inter-observer reliability was rated excellent. CONCLUSION: THA planning with 2DLD imaging is subject to variation in magnification as analyzed with conventional planning software in this series. This finding is of paramount importance for surgeons using 2DLD imaging in preparation for THA since errors in magnification could affect the accuracy of preoperative planning and ultimately the clinical outcome.

Excellent Correlation of the Patient-Reported Outcomes Measurement Information System Upper Extremity Score With Legacy Outcome Scores Preoperatively and at 1 Year After Arthroscopic Rotator Cuff Repair.

Purpose: To assess the preoperative and postoperative performance of the Patient-Reported Outcomes Measurement Information System Upper Extremity (PROMIS-UE, version 2.0) outcome score in comparison to the American Shoulder and Elbow Surgeons (ASES) and Western Ontario Rotator Cuff Index (WORC) instruments in patients undergoing rotator cuff repair. Methods: This prospective longitudinal study included 91 patients undergoing rotator cuff repair. Patients completed the PROMIS-UE, ASES, and WORC instruments preoperatively and postoperatively at 2 weeks, 6 weeks, 3 months, and 12 months. The Pearson correlation coefficient (r) between these tools was calculated at each time point. Correlations were graded as excellent (>0.7), excellent-good (0.61-0.7), good (0.4-0.6), or poor (<0.4). Responsiveness to change was assessed using the effect size and the standardized response mean. Floor and ceiling effects for each instrument were also assessed. Results: The PROMIS-UE instrument showed good to excellent correlation with the legacy instruments at all time points. There were variations in the measured effect sizes of the various instruments, with the PROMIS-UE instrument showing responsiveness to change at 3 and 12 months but the ASES and WORC instruments showing responsiveness at 6 weeks, 3 months, and 12 months. Both PROMIS-UE and ASES scores displayed ceiling effects at 12 months. Conclusions: The PROMIS-UE instrument shows excellent correlation with the ASES instrument and a rotator cuff-specific outcome instrument-the WORC instrument-preoperatively and at 1 year after arthroscopic rotator cuff repair. Variations in the measured effect sizes at different postoperative time points and high ceiling effects of the PROMIS-UE instrument at the 1-year time point may limit its utility in the early postoperative phase and at long-term follow-up after rotator cuff repair. Clinical Relevance: The performance of the PROMIS-UE outcome measure after arthroscopic rotator cuff repair was investigated.

Analysis of patient factors associated with selection of corticosteroid injection in the freezing phase of idiopathic adhesive capsulitis.

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.

Total knee arthroplasty in patients with lumbar spinal fusion leads to significant changes in pelvic tilt and sacral slope.

BACKGROUND: The knee-hip-spine syndrome has been well elucidated in the literature in recent years. The aim of this study was to evaluate the effect of total knee arthroplasty (TKA) on spinopelvic sagittal alignment in patients with and without pre-TKA lumber spinal fusion. METHODS: This is a retrospective cohort study of 113 patients who underwent TKA for primary osteoarthritis. Patients were stratified into the following three groups: (1) patients who had pre-TKA spinal fusion (SF, n = 19), (2) patients who had no spinal fusion but experienced pre-TKA flexion contracture (FC, n = 20), and (3) patients without flexion contracture or spinal fusion before TKA (no SF/FC, n = 74). Spinopelvic sagittal alignment parameters, including pelvic tilt (PT), sacral slope (SS), lumbar lordosis (LL), thoracic kyphosis (TK), and plumb line-sacrum distance (SVA) were measured preoperatively and 3 months postoperatively on lateral standing full-body low-dose images. RESULTS: TKA resulted in significant pre- to postoperative changes in pelvic tilt (average ∆ PT = - 8.6°, p = 0.018) and sacral slope (average ∆ SS = 8.6°, p = 0.037) in the spinal fusion (SF) group. Non-significant changes in spinopelvic sagittal alignment parameters (PT, SS, LL, TK, SVA) were noted postoperatively in all patients in the FC and the no SF/FC groups. CONCLUSIONS: TKA can lead to meaningful changes in spinopelvic alignment in patients with prior lumbar fusion compared to those without spinal fusion. Patients with spinal fusion who are candidates for both hip and knee replacements should consider undergoing TKA first since changes in spinopelvic sagittal alignment can increase the risk of future complications. LEVEL III EVIDENCE: Retrospective Cohort Study.

Outcomes of arthroscopic tuberoplasty for symptomatic irreparable rotator cuff tendon tear without pseudoparalysis.

Background: The purpose of this study is to report the outcomes in patients undergoing arthroscopic tuberoplasty for symptomatic irreparable rotator cuff tear (RCT). Methods: This is a retrospective cohort study comparing preoperative and postoperative data of patients undergoing arthroscopic tuberoplasty for symptomatic irreparable RCT. Exclusion criteria included open tuberoplasty, concomitant partial RCT repair, glenohumeral arthritis, concomitant ipsilateral extremity fractures, <12 months follow-up, or pseudoparalysis. Demographics, shoulder range of motion (ROM), RCT morphology, re-operation rates, satisfaction and outcome scores were collected from medical records and questionnaires. Outcome scores included Patient Reported Outcome Measurement Information System Upper Extremity (PROMIS), American Shoulder and Elbow Surgeons score (ASES), Subjective Shoulder Value (SSV), and pain Visual Analog Score (VAS). Results: Out of 28 patients identified between 2012 and 2019, 20 (21 shoulders) were available for follow-up at a mean of 43.3 ± 20.9 months. Mean age was 64.6 ± 8.8 years. Mean PROMIS was 37.7 ± 7.3, ASES was 82.9 ± 13.8, and SVV was 67.1 ± 19.4. VAS with activity decreased from 5.0 ± 2.9 preoperatively to 2.3 ± 2.6 (P = .0029). Pre- and post-operative ROM were unchanged. There were 4 failures requiring revision. The remaining 17 patients reported high satisfaction scores (3.4 ± 0.7) and 15 (88.2%) answered "yes" to getting the procedure again, with 3/4 failures stating they would also undergo arthroscopic tuberoplasty again. Conclusion: Arthroscopic tuberoplasty demonstrates high levels of satisfaction and pain reduction in symptomatic irreparable RCT. In appropriately indicated patients, this treatment should be considered prior to other salvage options.

Analysis of patient's willingness and concerns for discharge following shoulder arthroplasty.

Background: Patient's willingness and barriers for discharge after shoulder arthroplasty (SA) has not been studied. The aim of this study was to prospectively analyze patient's willingness for discharge and barriers to discharge beyond postoperative day #1 (POD#1) after SA. Methods: In this prospective study, patients undergoing primary or revision SA (anatomic, reverse, or hemiarthroplasty) at our institution were enrolled to determine their willingness and concerns for discharge after SA. Patient's willingness for discharge was inquired daily until discharge. Demographic information, patient's medical history, intraoperative details (duration of surgery, estimated blood loss, intraoperative complication), discharge disposition, length of stay (LOS), and reasons for extension of LOS beyond POD#1 were analyzed. Results: A total of 184 patients who underwent SA were included. Eight patients were discharged on POD#0, 114 patients on POD#1, 37 patients on POD#2, and 25 patients after POD#2. One hundred nineteen (119) patients were discharged to home, 40 were discharged to home with services, 15 were discharged to nursing facilities, and 10 were discharged to rehabilitation centers. Reasons for extension of LOS past POD#1 included patients failing to clear home safety evaluation (n = 4), inadequate pain control (n = 6), worsening of preexisting medical conditions (n = 8), delay in patient disposition (awaiting placement in a rehabilitation facility [n = 6] and awaiting culture results [n = 9]). Social reasons (n = 29) were the most common reasons for extension of LOS. These included patients requesting an extra day of stay (n = 20), patients requesting rehabilitation facility placement (n = 5), lack of a timely ride home (n = 2), and family-related reasons (death in the family [n = 1], lack of home help [n = 1]). Conclusions: This prospective study demonstrates modifiable factors associated with LOS beyond POD#1 (inadequate pain control, logistic delays in disposition, and patient-related social concerns) after SA. With increasing interest in same-day discharge and rising concerns to control cost and use bundled payment initiatives with SA, improving patient's willingness to discharge by addressing their concerns can improve early discharge after SA.

Outcomes of reverse shoulder arthroplasty following failed superior capsular reconstruction.

BACKGROUND: History of prior rotator cuff repair (RCR) may adversely affect the outcomes of reverse total shoulder arthroplasty (RTSA), but there is no information regarding the influence of prior superior capsular reconstruction (SCR) surgery on the outcomes of RTSA. The purpose of this study is to evaluate the outcomes of RTSA following failed arthroscopic SCR. METHODS: All patients who underwent RTSA for failed SCR (SCR cohort) at our institution were identified from our institutional database. A comparative cohort of patients who had RTSA with a history of failed RCR (Control cohort) was also reviewed. Demographic information, 90-day complication rate, 90-day emergency department visits, length of stay, and outcome scores (patient-reported outcomes measurement information system [PROMIS] physical function upper extremity, Visual Analog Scale score, and range of motion) were compared. RESULTS: From 2015 to 2020, 87 arthroscopic SCRs were performed at our institution and of these, 13 patients underwent RTSA at a mean time of 14.6 months (5.8-32.4) after SCR and were followed up for an average of 17.9 months (1.6-44.6). The average number of shoulder surgeries prior to RTSA was 2.8 (1-7), with the last surgery being SCR. During the same period, we identified 15 patients who underwent an RTSA after a failed RCR (control cohort). The RTSA in the control cohort was performed on average at 12.8 months (1.5-39.5) following the last RCR, and patients were followed up for an average of 27.7 months (2.8-53.9). The average number of shoulder surgeries before the RTSA in the control cohort was 1.4 (1-3). Although the SCR cohort had significant improvements in pain scores and forward flexion (FF), there was only a modest functional improvement with PROMIS scores and no meaningful improvement with external rotation. Complications (23%) in the SCR cohort included 1 periprosthetic joint infection requiring 2-stage revision, 1 acromion stress fracture, and 1 ulnar neuritis. Overall, compared to the SCR cohort, patients in the control cohort had better function (PROMIS physical function upper extremity), lower Visual Analog Scale score, and greater range of motion (FF and external rotation) preoperatively and at last follow-up, but there were no differences in the length of stay and 90-day emergency department visits, infection, and complication rate between the 2 cohorts. CONCLUSION: RTSA after failed SCR improves pain and FF but is associated with modest functional improvements and high complication rates. However, these findings will require confirmation in a larger cohort with longer follow-up.

Effect of Total Knee Arthroplasty on Coronal Alignment of the Ankle Joint.

BACKGROUND: The effect of total knee arthroplasty (TKA) on the ankle joint is not entirely clear. The purpose of this study is to assess postoperative changes in the coronal alignment of the ankle joint in patients undergoing TKA for various degrees of knee deformity. METHODS: This retrospective study included 107 patients who had undergone TKA for primary osteoarthritis. In all cases, preoperative coronal alignment deformity of the knee was corrected in an attempt to restore the native mechanical axis of the knee. Patients were stratified into 3 groups according to the degree of knee coronal alignment correction achieved intraoperatively: group 1 (<10° varus/valgus correction, n = 60), group 2 (≥10° varus correction, n = 30), and group 3 (≥10° valgus correction, n = 17). Knee/ankle alignment angles were measured on full-length, standing anteroposterior imaging preoperatively and postoperatively and included the following: hip-knee-ankle angle, tibial plafond inclination (TPI), talar inclination (TI), and tibiotalar tilt angle. RESULTS: Significant changes in ankle alignment, specifically with regard to TPI (9.5° ± 6.9°, P < .01) and TI (8.8° ± 8.8°, P = .03) were noted in the ≥10° valgus correction group compared to the other 2 groups. Regardless of the degree of knee deformity correction, TKA did not lead to significant changes in the tibiotalar tilt angle. CONCLUSION: A correction of ≥10° in a genu valgum deformity can affect ankle joint alignment, leading to alterations in TPI and TI. These findings need to be taken into consideration in assessing candidates for TKA as a possible cause of postoperative ankle pain.

Radiographic and clinical characterization of coracoid fractures: a retrospective cohort analysis.

PURPOSE: Coracoid fracture is a rare injury. The aim of this study is to present the demographics, clinical and radiologic characteristics, and outcomes of coracoid fracture in a cohort of 32 patients. METHODS: We queried our institutional electronic medical record database (years 2012-2020) to identify patients with coracoid fractures using specific International Classification of Disease-10 codes. Demographic data, injury details including mechanism of injury and associated injuries, imaging performed, and treatment outcomes were obtained from retrospective chart review. A radiologist reviewed all available imaging studies (radiographs/CT/MRI) and classified the fractures according to Ogawa and Eyres classifications. Missed diagnoses were determined by comparing initial imaging reports with the follow-up imaging obtained in the office. RESULTS: Thirty-two patients with coracoid fractures were identified during the study period. Sixteen fractures (50%) occurred in the setting of low-energy trauma. Twelve fractures were missed on initial radiographs, and diagnosis with three-view radiographs (AP, scapular-Y and axillary) was 88% compared to 33% (p < 0.03) with two views (AP, scapular-Y). The majority of fractures were non-displaced (94%), and 56% were Ogawa Type-II fractures. Associated injuries were seen in 81% of patients. Most fractures (94%) were treated without surgery with excellent outcomes. CONCLUSION: Coracoid fractures continue to be a rare injury. In contrast to previous studies, in this case series of 32 patients, half of the fractures were associated with low-energy trauma, which correlated with higher percentage of non-displaced fractures and Ogawa Type-II fractures. Addition of the axillary view in the trauma radiographic series significantly improved the initial fracture detection rate. LEVEL IV: Retrospective study.

Minimal clinically important difference, substantial clinical benefit, and patient acceptable symptom state of PROMIS upper extremity after total shoulder arthroplasty.

BACKGROUND: 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: 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: 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: 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.

Pectoralis Major Tendon Tear: A Critical Analysis Review.

¼: Pectoralis major (PM) tendon tears are predominantly seen in young men, and the majority of tears occur as tendon avulsions involving the sternal head. Weightlifting, specifically bench-pressing, and sporting activities with eccentric overloading of the PM tendon are the 2 most common activities that result in PM injury. ¼: Early surgical repair or reconstruction should be offered to younger, active patients with a complete PM tear; the majority of the patients undergoing surgical repair achieve good-to-excellent outcomes. ¼: Nonsurgical treatment of a complete PM tear is an option but will result in cosmetic deformity and a deficit in adduction strength of the arm. Outcomes after nonsurgical treatment of complete PM tears are less satisfactory than those obtained after surgical treatment. ¼: Currently, there is no consensus on the chronological definition of PM tears (acute versus chronic), the critical time limit for performing surgical repair, the ideal fixation device (cortical button, bone tunnel, or suture anchors), the indications for allograft use, and the ideal rehabilitation protocol after treatment of PM tears.

Complex Region Pain Syndrome Following Shoulder Surgery.

PURPOSE: To describe the clinical features, treatment, and outcomes in patients with complex region pain syndrome (CRPS) following shoulder surgeries. METHODS: Three patients were diagnosed with CRPS according to the Budapest criteria. Patients were followed up prospectively at regular intervals for a minimum of 2 years. Demographic data, clinical symptoms, physical examination findings, treatment received, and outcomes were collected and reported. RESULTS: The minimum time interval between surgery and diagnosis was 3 weeks (average, 8 weeks). The index procedures included 2 arthroscopic rotator cuff repairs and 1 open Latarjet. Neurologic pain, muscle spasms, hand and wrist swelling, and joint stiffness were seen in the shoulder, wrist, and hand, but the elbow was spared in all patients. Despite the use of multimodal treatment modalities, the symptoms were refractory to treatment for prolonged periods (range, 6-12 months). Hand and wrist symptoms took an average of 4 months longer than shoulder symptoms to improve. At the latest follow-up (range, 24-26 months), varying degrees of residual hand dysfunction, pain, and inability to make a fist or fully extend the fingers were noted in all 3 patients. CONCLUSIONS: CPRS type 1 following shoulder surgery is a disabling condition with a long-protracted clinical course. CRPS can present as early as few weeks after shoulder surgery, with symptoms of neuropathic pain, spasm, and stiffness affecting the entire upper-extremity joints except the elbow. CRPS symptoms resolve earlier in the shoulder compared with the wrist and hand, with pain improving first, followed by recovery of motion and function. Residual stiffness affecting grip function is last to recover and can present up to 2 years after onset of symptoms. Although prompt recognition and multimodal approach are considered the mainstay of treatment, there is no gold standard treatment modality that can reproducibly alter the natural history of CRPS. LEVEL OF EVIDENCE: IV, therapeutic case series.

The future of health care service in orthopedic practice: telemedicine or in-person visits?

BACKGROUND: The objective of this study was to assess patient satisfaction and preference for telemedicine vs. in-person visits for outpatient shoulder and elbow musculoskeletal consultation during the coronavirus disease 2019 (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 visits during the pandemic and preference for using the telemedicine platform in the future, following the pandemic. Additional details regarding their virtual visits (severity of medical condition, as well as previous virtual or emergency department visits) were also obtained. Data regarding patient demographic characteristics and visit details (primary diagnosis, type of visit, length of visit, and treating physician) were extracted from the electronic medical records. RESULTS: In total, 153 patients participated in the study. Overall, high satisfaction scores regarding the telemedicine visits 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 the telemedicine platform again in the presence of a situation similar to 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 > 10 minutes and a first-time telemedicine visit correlated with higher satisfaction rates (P = .037 and P = .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 owing 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.

Locked Anterior-Inferior Sternoclavicular Joint Dislocation: A Case Report.

CASE: We report a rare variant of sternoclavicular joint (SCJ) dislocation, namely locked anterior-inferior dislocation, with unique clinical, radiographic, and intraoperative findings. In this variant, the medial clavicle was displaced anteriorly and inferiorly and locked in the manubrial-intercostal space, with corresponding mechanical dysfunction of the ipsilateral shoulder girdle joints. Symptoms unique to this variant included painful neck spasms and limited glenohumeral elevation. Nonsurgical treatment was not successful, and open reduction and ligament reconstruction resulted in correction of the fixed deformity with resolution of the clinical symptoms. CONCLUSION: Locked anterior-inferior SCJ dislocation is indicated for early open reduction and ligament reconstruction.

Both Open and Arthroscopic Latarjet Result in Excellent Outcomes and Low Recurrence Rates for Anterior Shoulder Instability.

PURPOSE: The purpose of this study is to evaluate the patient-reported outcomes of open Latarjet (OL) compared to arthroscopic Latarjet (AL) for anterior shoulder instability. METHODS: A retrospective review of patients who underwent either OL or AL for anterior shoulder instability between 2011 and 2019 was performed. Recurrent instability, visual analog scale (VAS) score, Shoulder Instability-Return to Sport after Injury (SIRSI), Subjective Shoulder Value (SSV), Western Ontario Shoulder Instability (WOSI) score, patient satisfaction, willingness to undergo surgery again, and return to work/sport (RTW/RTS) were evaluated. A P value of < .05 was considered to be statistically significant. RESULTS: Our study included 102 patients in total; 72 patients treated with OL, and 30 treated with AL. There were no demographic differences between the two groups (P > .05 for all). At final follow up (mean of 51.3 months), there was no difference between those that underwent OL or AL in the reported WOSI, VAS, VAS during sports, SSV, and SIRSI scores, nor in patient satisfaction, or whether they would undergo surgery again (P > .05). Overall, there was no significant difference in the total rate of RTP (65% vs 60.9%; P = .74), or timing of RTP (8.1 months vs 7 months; P = .35). Additionally, there was no significant difference in the total rate of RTW (93.5% vs 95.5%; P = .75). Overall, 3 patients in the OL group and 2 patients in the AL group had recurrent instability events (6.9% vs 6.7%; P = .96), with no significant difference in the rate of recurrent dislocation (4.2% vs 3.3%; P = .84). CONCLUSION: In patients with anterior shoulder instability, both the OL and AL are reliable treatment options, with a low rate of recurrent instability, and similar patient-reported outcomes.
