RESUMEN
Background: Suture anchors have been used in surgical repair of acromioclavicular joint (ACJ) dislocation. While some reports indicate favorable results, others emphasize less promising outcomes. This case series reports our experience with suture anchors for surgical treatment of ACJ dislocation. Methods: Clinical and radiographic outcomes in three patients treated operatively for ACJ dislocations were reviewed. In all patients, two suture anchors were inserted in the coracoid (unicortical) and #5 nonabsorbable suture from the suture anchor was shuttled through drill holes in the clavicle and tied over two button devices. The coracoclavicular ligaments were reconstructed using a figure of eight semitendinosus allograft around the coracoid and clavicle. Postoperatively, sling immobilization was used for 6 weeks, and physical therapy was initiated at 6 weeks with contact activity allowed at 6 months. Results: Three male patients underwent treatment for Rockwood type 3 (chronic; n = 1) and type 5 (n = 2) ACJ dislocations. Loss of reduction was noted within 6 weeks postoperatively. Two patients exhibited failure due to complete suture anchor pullout and the third patient had partial pull out of one of the anchors. Additionally, the third patient also suffered a coracoid fracture adjacent to the anchor's placement after sustaining direct trauma to his shoulder, one-year postoperatively. Conclusion: In our case series, we found a high rate of fixation failure and early loss of reduction with the use of suture anchors for the treatment of ACJ dislocation. These findings should be taken into consideration when selecting an appropriate implant for fixation of ACJ dislocation.
RESUMEN
BACKGROUND: In the past decade the prevalence of end stage inflammatory elbow arthritis has declined with consequential changes in indications and utilization of total elbow arthroplasty (TEA). Current literature lacks future projections for the utilization of TEA. This aim of this study is to review the trends in utilization of TEA in last two decades and determine the projections of utilization for TEA (primary and revision) through 2060. METHODS: This analysis utilized the publicly available 2000-2019 data from the CMS Medicare Part-B National Summary. Procedure volumes including TEA, and revision TEA, were determined using current procedural terminology (CPT) codes and were uplifted to account for the growing number of Medicare eligible patients covered under Medicare Advantage. Using these volumes log-linear, Poisson, negative binomial regression, and autoregressive integrated moving average (ARIMA) models were applied to generate projections from 2020-2060. The Poisson model was chosen to display the data based on error analysis and prior literature. RESULTS: The projected annual growth rate from 2020 to 2060 for primary and revision TEA are 1.03% growth (95% CI 0.82% - 1.25%) and 5.17% growth (95% CI 3.02%-6.97%), respectively. By 2060, the demand for primary TEA and revision TEA is projected to be 2084 procedures (95% FI 1995 - 2174) and 3161 procedure (95% FI 3052 - 3272), respectively. The procedure volume for revision TEA is estimated to outnumber primary TEA by year 2050. CONCLUSION: The overall procedural volume of primary TEA, and revision TEA continues to be low. Although it is estimated that the incidence of primary and revision TEA will continue to increase in next 40 years, the utilization trends only show mild increase, which is five times higher for revision TEA compared to primary TEA.
RESUMEN
Aim: Retinal cell therapy modalities, in the category of advanced therapy medicinal products (ATMPs), are being developed to target several retinal diseases. Testing in large animal models (LAMs) is a crucial step in translating retinal ATMPs into clinical practice. However, challenges including budgetary and infrastructure constraints can hinder LAM research design and execution. Here, to facilitate the comparison of the various LAMs in pluripotent retinal cell therapy research, we aimed to systematically evaluate the species distribution, reported scientific utility, and methodology of a range of LAMs. Methods: A systematic search using the words retina, stem cell, transplantation, large animal, pig, rabbit, dog, and nonhuman primate was conducted in the PubMed, Embase, Science Direct and GoogleScholar databases in February 2023. Results: We included 22 studies involving pluripotent stem cells (induced pluripotent stem cells or human embryonic stem cells) in LAMs, including non-human primates (NHP), pigs, dogs, and rabbits. Nearly half of the studies utilized wild-type animal models. In other studies, retinal degeneration features were simulated via laser, chemical, or genetic insult. Transplants were delivered subretinally, either as cell suspensions or pre-formed monolayers (with or without biodegradable scaffolding). The transplanted cells dose per eye varied widely (40,000 - 4,000,000 per dose). Cells were delivered via vitrectomy surgery in 15 studies and by an "ab externo" approach in one study. Structural outcomes were assessed using confocal scanning laser ophthalmoscopy imaging. Functional outcomes included multifocal electroretinogram and, in one case, a measure of visual acuity. Generally, cell suspension transplants exhibited low intraretinal incorporation, while monolayer transplants incorporated more efficiently. Immune responses posed challenges for allogeneic transplants, suggesting that autologous iPSC-derived transplants may be required to decrease the likelihood of rejection. Conclusion: The use of appropriate LAMs helps to advance the development of retinal ATMPs. The anatomical similarity of LAM and human eyes allows the implementation of clinically-relevant surgical techniques. While the FDA Modernization Act 2.0 has provided a framework to consider alternative methods including tissue-on-a-chip and human cell culture models for pharmacologic studies, LAM testing remains useful for cell and tissue replacement studies to inform the development of clinical trial protocols.
RESUMEN
BACKGROUND: Healthcare disparity exists in utilization and delivery of musculoskeletal care and continues to be an obstacle for orthopedic healthcare providers to mitigate. Racial and ethnic disparities exist within various surgical fields including orthopedic surgery and are expected to continue to rise in upcoming years. The aim of this systematic review is to analyze the racial and ethnic disparities on utilization and outcomes after common shoulder surgical procedures. QUESTIONS/PURPOSE: Are there racial or ethnic disparities in outcomes and utilization of shoulder surgeries? Is there evidence to explain the etiology underlying the differences in outcomes among racial and ethnic groups after shoulder surgery? PATIENTS/METHODS: A primary literature search was performed using PubMed, Embase, Cochrane Central Register of Controlled Trials, and Clinicaltrials.gov databases using comprehensive Medical Subject Headings and subject-heading search terms. Studies were included if they reported utilization and or outcomes across two or more racial/ethnic groups in patients (age >16) who underwent shoulder arthroplasty (TSA), rotator cuff repair (RCR), arthroscopic Bankart repair (ABR), Latarjet (LP) and internal fixation (ORIF) of PHF. Baseline demographics, data on procedure utilization, perioperative measures including mortality, operative time, length of stay (LOS), readmission and complications were extracted from included studies, and descriptive statistical analysis performed. RESULTS: Eighteen studies were identified for full text review of which 13 found race and ethnicity as factors affecting utilization and outcomes in TSA, RCR, ABR, LP and ORIF of PHF. Compared to White patients, Black patients were found to have decreased utilization, longer LOS, and greater operative time and mortality after TSA; Black patients also had longer operative times and time to discharge, and lower levels of reported satisfaction after RCR. Hispanic/Latino ethnicity was reported as an independent risk factor for post operative falls following TSA. Hispanic/Latino and Black patients have a higher risk of delayed surgery and greater risk of readmission after surgical treatment of PHF compared to patients of White race. CONCLUSION: This systematic review highlights the limited literature reporting the existence of racial and ethnic disparities in utilization and outcomes after common shoulder surgical procedures. Additionally, there is paucity of studies exploring the underlying etiology of racial and ethnic disparity in outcomes after shoulder surgery. More research is necessary to pave the way for evidence-based action plans to mitigate healthcare disparities after shoulder surgeries, but this review serves as a baseline for where efforts in direct improvement can begin.
RESUMEN
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: Talar neck non-unions result in significant hindfoot deformity and morbidity and are infrequently reported in the literature. The optimal surgical management for this condition is evolving, with various authors reporting the results of open reduction and internal fixation (ORIF) with bone grafting (BG), ankle fusion and modified Blair fusion. We performed this study to report the clinical and radiological outcomes of a cohort of talar neck non-unions managed by ankle joint preserving reconstruction. METHODS: This was an ambispective study which included 8 patients (7 male and 1 female) with talar neck non-unions. All patients underwent ORIF+BG through dual approaches. Additional medial malleolar osteotomy was done in 2 cases, and calcaneofibular split approach to the subtalar joint in 3. Adjunct subtalar fusion was done in 5 cases. Clinical and radiological evaluation was performed pre- and post-operatively. Functional outcomes were assessed by the Manchester Oxford Foot Questionnaire (MOxFQ). RESULTS: The mean age of patients 32.3 ± 13.1 years. The mean surgical delay was 4.1 ± 1.7 months. As per Zwipp and Rammelt classification of post-traumatic talar deformities, 5 cases were classified as Type 3, 2 were Type 4, and 1 was Type 1. Union was achieved in 7 cases at a mean of 3.4 ± 1.3 months. One case had progressive collapse, which was managed by pantalar arthrodesis. All 3 cases where subtalar fusion was not performed primarily demonstrated subtalar arthrosis, but none required a secondary subtalar fusion. The MOxFQ score from 61.1 ± 10.1 to 41 ± 14.1 postoperatively (P = 0.005). The mean follow-up was 14.6 ± 6.8 months. CONCLUSION: ORIF+BG of the talar neck, with or without subtalar fusion has the potential to achieve solid union, correct the hindfoot deformity and improve functional outcomes. However, larger studies with longer follow-up are needed to evaluate the long-term efficacy of this procedure.

BACKGROUND AND AIMS: The aim of this study was to determine the prognostic value of coronary computed tomography angiography (CCTA)-derived atherosclerotic plaque analysis in ISCHEMIA. METHODS: Atherosclerosis imaging quantitative computed tomography (AI-QCT) was performed on all available baseline CCTAs to quantify plaque volume, composition, and distribution. Multivariable Cox regression was used to examine the association between baseline risk factors (age, sex, smoking, diabetes, hypertension, ejection fraction, prior coronary disease, estimated glomerular filtration rate, and statin use), number of diseased vessels, atherosclerotic plaque characteristics determined by AI-QCT, and a composite primary outcome of cardiovascular death or myocardial infarction over a median follow-up of 3.3 (interquartile range 2.2-4.4) years. The predictive value of plaque quantification over risk factors was compared in an area under the curve (AUC) analysis. RESULTS: Analysable CCTA data were available from 3711 participants (mean age 64 years, 21% female, 79% multivessel coronary artery disease). Amongst the AI-QCT variables, total plaque volume was most strongly associated with the primary outcome (adjusted hazard ratio 1.56, 95% confidence interval 1.25-1.97 per interquartile range increase [559 mm3]; P = .001). The addition of AI-QCT plaque quantification and characterization to baseline risk factors improved the model's predictive value for the primary outcome at 6 months (AUC 0.688 vs. 0.637; P = .006), at 2 years (AUC 0.660 vs. 0.617; P = .003), and at 4 years of follow-up (AUC 0.654 vs. 0.608; P = .002). The findings were similar for the other reported outcomes. CONCLUSIONS: In ISCHEMIA, total plaque volume was associated with cardiovascular death or myocardial infarction. In this highly diseased, high-risk population, enhanced assessment of atherosclerotic burden using AI-QCT-derived measures of plaque volume and composition modestly improved event prediction.
RESUMEN
BACKGROUND: In the past few decades, the primary management for uveal melanoma has evolved from enucleation to eye-preserving treatments. However, despite achieving a high rate of local tumour control, complications following eye-preserving treatments still occur and are partly responsible for functional loss and secondary enucleation. METHODS: A literature review by a broad international panel. RESULTS: We summarised the current literature on utilizing vitreoretinal (VR) surgery for managing the complications of uveal melanoma. We also provided insights from the authors' personal experience and practical recommendations for clinical care. CONCLUSIONS: With the advancement of VR instruments and surgical techniques and the combination of VR and ocular oncology knowledge ("Onco-VR"), it is now possible to manage or even prevent complications such as vitreous haemorrhage, retinal detachment, and toxic tumour syndrome.
RESUMEN
PURPOSE: To evaluate high-risk histopathological features (HRHF) following primary enucleation of eyes with retinoblastoma (RB) and assess the patient outcomes across continents. METHODS: Retrospective study of 1426 primarily enucleated RB eyes from five continents. RESULTS: Of all, 923 (65%) were from Asia (AS), 27 (2%) from Australia (AUS), 120 (8%) from Europe (EUR), 162 (11%) from North America (NA), and 194 (14%) from South America (SA). Based on the continent (AS vs. AUS vs. EUR vs. NA vs. SA), the histopathology features included massive choroidal invasion (31% vs. 7% vs. 13% vs. 19% vs. 27%, p=0.001), post-laminar optic nerve invasion (27% vs. 0% vs. 16% vs. 21% vs. 19%, p=0.0006), scleral infiltration (5% vs. 0% vs. 4% vs. 2% vs. 7%, p=0.13), and microscopic extrascleral infiltration (4% vs. 0% vs. <1% vs. <1% vs. 4%, p=0.68). Adjuvant chemotherapy with/without orbital radiotherapy was given in 761 (53%) patients. Based on Kaplan-Meier estimates in different continents (AS vs. AUS vs. EUR vs. NA vs. SA), the 6-year risk of orbital tumor recurrence was 5% vs. 2% vs. 0% vs. 0% vs. 12% (p<0.001), systemic metastasis was reported in 8% vs. 5% vs. 2% vs. 0% vs. 13% (p=0.001), and death in 10% vs. 3% vs. 2% vs. 0% vs. 11% (p<0.001) patients. CONCLUSION: There is a wide variation in the infiltrative histopathology features of RB across continents, resulting in variable outcomes. SA and AS had a higher risk of orbital tumor recurrence, systemic metastasis, and death compared to AUS, EUR, and NA.
RESUMEN
Introduction: Retinal focal nodular gliosis (FNG), also known as vasoproliferative tumors (VPTs), are rare, benign vascular tumors associated with exudation with no current consensus on management. Herein, we describe the varied clinical course and management of 3 patients with retinal FNG, one of whom is associated with retinitis pigmentosa. Case Presentations: Case 1 is a 76-year-old female who presented with reduced vision and distortion secondary to a vitreous hemorrhage and epiretinal membrane (ERM) as complications of a known small peripheral retinal FNG. She underwent vitrectomy for the hemorrhage to relieve vascular traction and the ERM peel, and the tumor was kept under observation. Case 2 is a 24-year-old female with genetically uncharacterized retinitis pigmentosa-like phenotype who presented with gradual loss of central vision in one eye due to cystoid macular oedema (CMO). She was found to have two peripheral retinal areas of FNG located inferonasally. Tumors were treated with cryotherapy and adjuvant intraocular steroid implant to control the CMO. Case 3 is a 28-year-old female with retinitis pigmentosa secondary to genetically confirmed variant in CRB1 gene who presented with intractable right eye CMO and localized inferior serous retinal detachment secondary to a large inferotemporal FNG. Her left eye has no light perception vision due to previous extensive serous retinal detachment and anterior segment ischemia. The right eye tumor was managed with multiple rounds of cryotherapy and laser therapy to control the serous detachment. Despite this, the condition progressed and was ultimately treated with plaque brachytherapy. Unfortunately, this resulted in extensive retinal inflammation causing annular tractional retinal detachment which was treated with combined pars plana vitrectomy and scleral buckle. Conclusion: We characterized the retinal phenotype of 3 patients with retinal FNG (VPTs) and found them to have varied clinical courses requiring tailored surgical management. The case associated with retinitis pigmentosa had a known pathogenic variant in Crumbs homolog-1 (CRB1) gene affecting retinal structure and exhibited a more severe clinical course. It is therefore important for patients with retinal dystrophies to undergo thorough peripheral examinations and detect FNG early as they may require prompt, aggressive treatment.
RESUMEN
AIM: To report local tumour control, metastasis and survival rates of patients with small choroidal melanoma (CM) after treatment with ruthenium-106 (Ru-106) plaque brachytherapy. METHODS: Retrospective case series of 353 consecutive eyes with small CM (thickness ≤2.5 mm and largest basal diameter ≤16 mm) treated with Ru-106 brachytherapy at the London Ocular Oncology Service, between October 2004 and May 2019. RESULTS: The final cohort included 310 eyes and tumour recurrence was observed in 52 (17%) eyes. Ocular retention rate was 96%. Metastatic disease and tumour-related death occurred in 18 (5.8%) and 12 (3.9%) patients, respectively. Metastases were diagnosed after a median of 54 (54±35; range 3.6-118) months from initial treatment. Kaplan-Meier estimates for tumour recurrence, melanoma-related metastases and survival were 17% (95% CI 13.3% to 22.9%), 4.8% (95% CI 2.6% to 8.5%) and 98% (95% CI 94.4% to 99.1%) at 5 years and 26% (95% CI 18.3% to 35.3%), 16% (95% CI 8.7% to 27.7%) and 92% (95% CI 84.5% to 95.7%) at 10 years, respectively. On multivariable analysis, factors predictive for tumour recurrence included juxtapapillary location, larger plaque and final tumour thickness, and for metastasis exudative retinal detachment. CONCLUSION: Small CMs treated with Ru-106 brachytherapy show recurrence and death rates of 17% and 2% at 5 years and 26% and 8% at 10 years. As small CMs have better prognosis than large tumours, early treatment is the key for better survival outcomes.
RESUMEN
OBJECTIVE: When the peritoneal cavity cannot serve as the distal shunt terminus, nonperitoneal shunts, typically terminating in the atrium or pleural space, are used. The comparative effectiveness of these two terminus options has not been evaluated. The authors directly compared shunt survival and complication rates for ventriculoatrial (VA) and ventriculopleural (VPl) shunts in a pediatric cohort. METHODS: The Hydrocephalus Clinical Research Network Core Data Project was used to identify children ≤ 18 years of age who underwent either VA or VPl shunt insertion. The primary outcome was time to shunt failure. Secondary outcomes included distal site complications and frequency of shunt failure at 6, 12, and 24 months. RESULTS: The search criteria yielded 416 children from 14 centers with either a VA (n = 318) or VPl (n = 98) shunt, including those converted from ventriculoperitoneal shunts. Children with VA shunts had a lower median age at insertion (6.1 years vs 12.4 years, p < 0.001). Among those children with VA shunts, a hydrocephalus etiology of intraventricular hemorrhage (IVH) secondary to prematurity comprised a higher proportion (47.0% vs 31.2%) and myelomeningocele comprised a lower proportion (17.8% vs 27.3%) (p = 0.024) compared with those with VPl shunts. At 24 months, there was a higher cumulative number of revisions for VA shunts (48.6% vs 38.9%, p = 0.038). When stratified by patient age at shunt insertion, VA shunts in children < 6 years had the lowest shunt survival rate (p < 0.001, log-rank test). After controlling for age and etiology, multivariable analysis did not find that shunt type (VA vs VPl) was predictive of time to shunt failure. No differences were found in the cumulative frequency of complications (VA 6.0% vs VPl 9.2%, p = 0.257), but there was a higher rate of pneumothorax in the VPl cohort (3.1% vs 0%, p = 0.013). CONCLUSIONS: Shunt survival was similar between VA and VPl shunts, although VA shunts are used more often, particularly in younger patients. Children < 6 years with VA shunts appeared to have the shortest shunt survival, which may be a result of the VA group having more cases of IVH secondary to prematurity; however, when age and etiology were included in a multivariable model, shunt location (atrium vs pleural space) was not associated with time to failure. The baseline differences between children treated with a VA versus a VPl shunt likely explain current practice patterns.
RESUMEN
PURPOSE: This study aimed to evaluate the accuracy of information that patients can obtain from large language models (LLMs) when seeking answers to common questions about choroidal melanoma. METHODS: Comparative study comparing frequently asked questions from choroidal melanoma patients and queried three major LLMs-ChatGPT 3.5, Bing AI, and DocsGPT. Answers were reviewed by three ocular oncology experts and scored as accurate, partially accurate, or inaccurate. Statistical analysis compared the quality of responses across models. RESULTS: For medical advice questions, ChatGPT gave 92% accurate responses compared to 58% for Bing AI and DocsGPT. For pre/post-op questions, ChatGPT and Bing AI were 86% accurate while DocsGPT was 73% accurate. There were no statistically significant differences between models. ChatGPT responses were the longest while Bing AI responses were the shortest, but length did not affect accuracy. All LLMs appropriately directed patients to seek medical advice from professionals. CONCLUSION: LLMs show promising capability to address common choroidal melanoma patient questions at generally acceptable accuracy levels. However, inconsistent, and inaccurate responses do occur, highlighting the need for improved fine-tuning and oversight before integration into clinical practice.
RESUMEN
Cardiorenal syndrome (CRS) due to right ventricular (RV) failure is a disease entity emerging as a key indicator of morbidity and mortality. The multifactorial aspects of CRS and the left-right ventricular interdependence complicate the link between RV failure and renal function. RV failure has a direct pathophysiological link to renal dysfunction by leading to systemic venous congestion in certain circumstances and low cardiac output in other situations, both leading to impaired renal perfusion. Indeed, renal dysfunction is known to be an independent predictor of mortality in patients with pulmonary arterial hypertension (PAH) and RV failure. Thus, it is important to further understand the interaction between the RV and renal function. RV adaptation is critical to long-term survival in patients with PAH. The RV is also known for its remarkable capacity to recover once the aggravating factor is addressed or mitigated. However, less is known about the renal potential for recovery following the resolution of chronic RV failure. In this review, we provide an overview of the intricate relationship between RV dysfunction and the subsequent development of CRS, with a particular emphasis on PAH. Additionally, we summarize potential RV-targeted therapies and their potential beneficial impact on renal function.
RESUMEN
INTRODUCTION: Respiratory Syncytial Virus (RSV) is a leading cause of acute lower respiratory infection in children worldwide. Understanding its prevalence, variations, and characteristics is vital, particularly in the context of the COVID-19 pandemic. OBJECTIVE: The study aimed to investigate the RSV positivity rate, subtype prevalence, age and gender distribution, symptomatology, and co-infection rates during pre-pandemic and pandemic periods. METHODS: We analyzed data from 15,381 patients tested for RSV between 2017 and 2023. RESULTS: Our analysis revealed a 7.2% average RSV positivity rate in the pre-pandemic period, with significant fluctuations during the pandemic (1.5% in 2020 to 32.0% in 2021). We observed variations in RSVA and RSVB detection rates. The 0-4 years' age group was consistently the most affected, with a slight male predominance. Fever and cough were common symptoms. Therapeutic interventions, particularly antiviral usage and ventilation requirements, decreased during the pandemic. We also identified variations in co-infection rates with other respiratory viruses. CONCLUSION: Our study offers critical insights into the impact of the COVID-19 pandemic on RSV prevalence, subtype distribution, patient characteristics, and clinical management. These findings underscore the need for ongoing surveillance and adaptive public health responses.

OBJECTIVE: To describe the development of a web-based data collection tool to track the management and outcomes of uveal melanoma patients. DESIGN: Description of a clinical registry. PARTICIPANTS: Patients with uveal melanoma. METHODS: A panel of expert ocular oncologists, with input from other relevant specialties and individuals with expertise in registry development, collaborated to formulate a minimum data set to be collected to track patient centred, real-world outcomes in uveal melanoma. This data set was used to create the Fight Tumour Blindness! (FTB!) registry within Save Sight Registries. RESULTS: The data set to be collected includes patient demographics and medical history, baseline visit, follow-up visit including tumour treatment, metastatic staging and surveillance, pathology, and patient-reported questionnaires. The inbuilt mechanisms to ensure efficient and complete data collection are described. CONCLUSIONS: The FTB! registry can be used to monitor outcomes for patients with uveal melanoma. It allows benchmarking of outcomes and comparisons between different clinics and countries.
RESUMEN
(1) Background: We reviewed a stem cell-derived therapeutic strategy for advanced neovascular age-related macular degeneration (nAMD) using a human embryonic stem cell-derived retinal pigment epithelium (hESC-RPE) monolayer delivered on a coated, synthetic basement membrane (BM)-the patch-and assessed the presence and distribution of hESC-RPE over 5 years following transplantation, as well as functional outcomes. (2) Methods: Two subjects with acute vision loss due to sub-macular haemorrhage in advanced nAMD received the hESC-RPE patch. Systematic immunosuppression was used peri-operatively followed by local depot immunosuppression. The subjects were monitored for five years with observation of RPE patch pigmentation, extension beyond the patch boundary into surrounding retina, thickness of hESC-RPE and synthetic BM and review for migration and proliferation of hESC-RPE. Visual function was also assessed. (3) Results: The two study participants showed clear RPE characteristics of the patch, preservation of some retinal ultrastructure with signs of remodelling, fibrosis and thinning on optical coherence tomography over the 5-year period. For both participants, there was evidence of pigment extension beyond the patch continuing until 12 months post-operatively, which stabilised and was preserved until 5 years post-operatively. Measurement of hESC-RPE and BM thickness over time for both cases were consistent with predefined histological measurements of these two layers. There was no evidence of distant RPE migration or proliferation in either case beyond the monolayer. Sustained visual acuity improvement was apparent for 2 years in both subjects, with one subject maintaining the improvement for 5 years. Both subjects demonstrated initial improvement in fixation and microperimetry compared to baseline, at year 1, although only one maintained this at 4 years post-intervention. (4) Conclusions: hESC-RPE patches show evidence of continued pigmentation, with extension, to cover bare host basement membrane for up to 5 years post-implantation. There is evidence that this represents functional RPE on the patch and at the patch border where host RPE is absent. The measurements for thickness of hESC-RPE and BM suggest persistence of both layers at 5 years. No safety concerns were raised for the hypothetical risk of RPE migration, proliferation or tumour formation. Visual function also showed sustained improvement for 2 years in one subject and 5 years in the other subject.
RESUMEN
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.

BACKGROUND: This study compares the outcomes of Latarjet-Patte procedures (LPs) performed for primary glenohumeral instability in the setting of critical bone loss (LP-BL) versus salvage surgery performed after a failed arthroscopic Bankart repair (LP-FB). METHODS: LP's performed by senior author from 2017 to 2021 were separated into cohorts by LP indication. Data abstracted from electronic medical records included demographic information, preoperative clinical scores, radiological imaging, and complications. Postoperative clinical outcome scores collected after a 2-year minimum follow-up included: patient-reported outcomes measurement information system (PROMIS) upper extremity (UE), PROMIS pain interference, PROMIS pain intensity, American Shoulder and Elbow Surgeons (ASES), and visual analog scale pain scores. RESULTS: A total of 47 patients (LP-BL: n=29, LP-FB: n=18) with a mean age of 29 years (range, 15-58 years) were included in this study. Both cohorts achieved good upper extremity functionality without significant differences as indicated by mean PROMIS UE (LP-BL: 52.6±10.0 vs. LP-FB: 54.6±7.6, P=0.442) and ASES score (LP-BL: 89.9±15.7 vs. LP-FB: 91.5±14.4, P=0.712). However, the LP-FB cohort reported lower levels of pain (LP-FB: 0.5±1.1 vs. LP-BL: 1.9±2.7, P=0.020) at their latest follow-up. There were no significant differences in complication rates including re-dislocation between cohorts (LP-BL: 2/29 [6.9%] vs. LP-FB: 2/18 [11.1%], P=0.629). CONCLUSIONS: When performed after failed Bankart repair, the LP results in similar postoperative functional outcomes and similar rates of complications and re-dislocations when compared to the primary indication of recurrent glenohumeral instability in the setting of critical bone loss. Level of evidence: III.
