RESUMO
BACKGROUND: Adolescent idiopathic scoliosis (AIS) is a structural lateral spinal curvature of ≥10° with rotation. Approximately 2%-3% of children across populations are affected with AIS, and this condition is responsible for ~$3 billion in costs within the USA. Although AIS is believed to have a strong genetic contribution, clinical translation of identified genetic variants has stalled. METHODS: The databases MEDLINE (via PubMed), Embase, Google Scholar and Ovid MEDLINE were searched and limited to articles in English. Title and abstract, full-text and data extraction screening was conducted through Covidence, followed by data transfer to a custom REDCap database. Studies containing variant-level data using genome-wide methodology as well as validation studies of genome-wide methods were considered. Quality assessment was conducted using Q-Genie. RESULTS: 33 studies were included, including 9 genome-wide association studies, 4 whole exome sequencing and 20 validation studies. Combined, these studies included data from >35,000 cases and >67,000 controls, not including validation cohorts. Additionally, results from six meta-analyses containing novel cohorts were also reported. All included study cohorts were from populations of primarily East Asian or Caucasian descent. Quality assessment found that overall study quality was high and control group selection was moderate. The highest number of reported associations were in single nucleotide polymorphisms (SNPs) in or near LBX1, LBX1-AS1, GPR126/ADGRG6 or BNC2. CONCLUSION: AIS risk may be influenced by specific SNPs, particularly those in/near LBX1 and GPR126. Translatability of study findings is unknown due to an underrepresentation of most ethnic groups as well as few identified genome-wide studies. Further studies may benefit from increased cohort diversity and thorough evaluation of control cohort groups.

BACKGROUND: Clubfoot, presenting as a rigid inward and downward turning of the foot, is one of the most common congenital musculoskeletal anomalies. The aetiology of clubfoot is poorly understood and variants in known clubfoot disease genes account for only a small portion of the heritability. METHODS: Exome sequence data were generated from 1190 non-syndromic clubfoot cases and their family members from multiple ethnicities. Ultra-rare variant burden analysis was performed comparing 857 unrelated clubfoot cases with European ancestry with two independent ethnicity-matched control groups (1043 in-house and 56 885 gnomAD controls). Additional variants in prioritised genes were identified in a larger cohort, including probands with non-European ancestry. Segregation analysis was performed in multiplex families when available. RESULTS: Rare variants in 29 genes were enriched in clubfoot cases, including PITX1 (a known clubfoot disease gene), HOXD12, COL12A1, COL9A3 and LMX1B. In addition, rare variants in posterior HOX genes (HOX9-13) were enriched overall in clubfoot cases. In total, variants in these genes were present in 8.4% (100/1190) of clubfoot cases with both European and non-European ancestry. Among these, 3 are de novo and 22 show variable penetrance, including 4 HOXD12 variants that segregate with clubfoot. CONCLUSION: We report HOXD12 as a novel clubfoot disease gene and demonstrate a phenotypic expansion of known disease genes (myopathy gene COL12A1, Ehlers-Danlos syndrome gene COL9A3 and nail-patella syndrome gene LMX1B) to include isolated clubfoot.

Poor bone quality is a risk factor for complications after spinal fusion surgery. This study investigated pre-operative bone quality in postmenopausal women undergoing spine fusion and found that those with small bones, thinner cortices and surgeries involving more vertebral levels were at highest risk for complications. PURPOSE: Spinal fusion is one of the most common surgeries performed worldwide. While skeletal complications are common, underlying skeletal deficits are often missed by pre-operative DXA due to artifact from spinal pathology. This prospective cohort study investigated pre-operative bone quality using high resolution peripheral CT (HRpQCT) and its relation to post-operative outcomes in postmenopausal women, a population that may be at particular risk for skeletal complications. We hypothesized that women with low volumetric BMD (vBMD) and abnormal microarchitecture would have higher rates of post-operative complications. METHODS: Pre-operative imaging included areal BMD (aBMD) by DXA, cortical and trabecular vBMD and microarchitecture of the radius and tibia by high resolution peripheral CT. Intra-operative bone quality was subjectively graded based on resistance to pedicle screw insertion. Post-operative complications were assessed by radiographs and CTs. RESULTS: Among 50 women enrolled (age 65 years), mean spine aBMD was normal and 35% had osteoporosis by DXA at any site. Low aBMD and vBMD were associated with "poor" subjective intra-operative quality. Skeletal complications occurred in 46% over a median follow-up of 15 months. In Cox proportional models, complications were associated with greater number of surgical levels (HR 1.19 95% CI 1.06-1.34), smaller tibia total area (HR 1.67 95% CI1.16-2.44) and lower tibial cortical thickness (HR 1.35 95% CI 1.05-1.75; model p < 0.01). CONCLUSION: Women with smaller bones, thinner cortices and procedures involving a greater number of vertebrae were at highest risk for post-operative complications, providing insights into surgical and skeletal risk factors for complications in this population.

OBJECTIVES: The purpose of this study was to assess morphological and quantitative changes of the anterior cruciate ligament (ACL) and cartilage after ACL repair. METHODS: 7T MRI of the knee was acquired in 31 patients 1.5 years after ACL repair and in 13 controls. Proton density-weighted images with fat saturation (PD-fs) were acquired to assess ACL width, signal intensity, elongation, and fraying. T2/T2* mapping was performed for assessment of ACL and cartilage. Segmentation of the ACL, femoral, and tibial cartilage was carried out at 12 ROIs. The outcome evaluation consisted of the Lysholm Knee Score and International Knee Documentation Committee (IKDC) subjective score and clinical examination. RESULTS: ACL showed a normal signal intensity in 96.8% and an increased width in 76.5% after repair. Fraying occurred in 22.6% without having an impact on the clinical outcome (Lysholm score: 90.39 ± 9.75, p = 0.76 compared to controls). T2 analysis of the ACL revealed no difference between patients and controls (p = 0.74). Compared to controls, assessment of the femoral and tibial cartilage showed a significant increase of T2* times in all ROIs, except at the posterolateral femur. Patients presented a good outcome in clinical examination with a Lysholm score of 87.19 ± 14.89 and IKDC of 80.23 ± 16.84. CONCLUSION: T2 mapping results suggest that the tissue composition of the ACL after repair is similar to that of a native ACL after surgery, whereas the ACL exhibits an increased width. Fraying of the ACL can occur without having any impact on functional outcomes. T2* analysis revealed early degradation at the cartilage. CLINICAL RELEVANCE STATEMENT: MRI represents a noninvasive diagnostic tool for the morphological and compositional assessment of the anterior cruciate ligament after repair, whereas knowledge about post-surgical alterations is crucial for adequate imaging interpretation. KEY POINTS: ⢠There has been renewed interest in repairing the anterior cruciate ligament with a proximally torn ligament. ⢠T2 times of the anterior cruciate ligament do not differ between anterior cruciate ligament repair patients and controls. ⢠T2 mapping may serve as a surrogate for the evaluation of the anterior cruciate ligament after repair.

INTRODUCTION: Traumatic injury is responsible for eight million childhood deaths annually. In Uganda, there is a paucity of comprehensive data describing the burden of pediatric trauma, which is essential for resource allocation and surgical workforce planning. This study aimed to ascertain the burden of non-adolescent pediatric trauma across four Ugandan hospitals. METHODS: We performed a descriptive review of four independent and prospective pediatric surgical databases in Uganda: Mulago National Referral Hospital (2012-2019), Mbarara Regional Referral Hospital (2015-2019), Soroti Regional Referral Hospital (SRRH) (2016-2019), and St Mary's Hospital Lacor (SMHL) (2016-2019). We sub-selected all clinical encounters that involved trauma. The primary outcome was the distribution of injury mechanisms. Secondary outcomes included operative intervention and clinical outcomes. RESULTS: There was a total of 693 pediatric trauma patients, across four hospital sites: Mulago National Referral Hospital (n = 245), Mbarara Regional Referral Hospital (n = 29), SRRH (n = 292), and SMHL (n = 127). The majority of patients were male (63%), with a median age of 5 [interquartile range = 2, 8]. Chiefly, patients suffered blunt injury mechanisms, including falls (16.2%) and road traffic crashes (14.7%) resulting in abdominal trauma (29.4%) and contusions (11.8%). At SRRH and SMHL, from which orthopedic data were available, 27% of patients suffered long-bone fractures. Overall, 55% of patients underwent surgery and 95% recovered to discharge. CONCLUSIONS: In Uganda, non-adolescent pediatric trauma patients most commonly suffer injuries due to falls and road traffic crashes, resulting in high rates of abdominal trauma. Amid surgical workforce deficits and resource-variability, these data support interventions aimed at training adult general surgeons to provide emergency pediatric surgical care and procedures.

Platelet-rich plasma (PRP) is the platelet and leukocyte-containing plasmatic fraction of anticoagulated autologous blood. While evidence supporting the clinical use of PRP in dentistry is low, PRP is widely used in sports medicine, orthopedics, and dermatology. Its beneficial activity is commonly attributed to the growth factors released from platelets accumulating in PRP; however, evidence is indirect and not comprehensive. There is thus a demand to revisit PRP with respect to basic and translational science. This review is to (i) recapitulate protocols and tools to prepare PRP; (ii) to discuss the cellular and molecular composition of PRP with a focus on platelets, leukocytes, and the fibrin-rich extracellular matrix of coagulated plasma; and finally (iii) to discuss potential beneficial effects of PRP on a cellular and molecular level with an outlook on its current use in dentistry and other medical fields.
RESUMO
BACKGROUND: The COVID-19 pandemic has affected all aspects of human life and society and has damaged the global economy. Health systems and hospitals were not exempted from this situation. The performance of hospitals during the COVID-19 pandemic was affected by policies related to the pandemic and other factors. This study aimed to investigate hospital performance indicators such as admissions and revenue. METHODS: The medical records of patients with selected orthopedic and general surgical diseases were studied in two government hospitals in the capital city of Urmia in the second quarter of 2019, with the same period in 2020. Data were extracted based on the number of medical records, including length of stay, hospitalization type, sex, age, insurance, number of deaths, and readmissions from the medical records department. Payment amounts were collected from the revenue department and Hospital Information System. Two performance indicators, two result indicators, and two control indicators were used. Mean disease-specific revenue, total revenue, length of stay, and bed occupancy rate were calculated for both periods. Data were analyzed using SPSS (version 16) and the Mann-Whitney statistical test. RESULTS: 2140 cases were studied in the two disease groups. An increase was observed in the number of hospitalizations and average length of stay during the pandemic. The mean disease-specific revenue in the quarter of 2020 was higher than in 2019. However, total revenue decreased, and the difference in the mean of total revenue was significant for the two years (P = 0.00) in teaching center. The number of readmissions remained unchanged throughout in the pandemic. The number of deaths due to general surgery diseases in 2020 compared to the same period in 2019 was associated with a relative increase. CONCLUSIONS: The COVID-19 pandemic increased the slope of health care costs. The analysis of the studied variables as performance, result, and control indicators showed that hospitalization rate, bed occupancy rate, and total revenue followed a similar and decreasing pattern in the selected hospitals during the COVID-19 pandemic. Hospitals should adopt appropriate strategies so that, in conditions identical to the COVID-19 pandemic, their performance is accompanied by proper management of resources, efficiency, and minimal reduction in revenue.
RESUMO
Congenital vertebral malformations (CVMs) and neural tube defects (NTDs) are common birth defects affecting the spine and nervous system, respectively, due to defects in somitogenesis and neurulation. Somitogenesis and neurulation rely on factors secreted from neighbouring tissues and the integrity of the axial structure. Crucial signalling pathways like Wnt, Notch and planar cell polarity regulate somitogenesis and neurulation with significant crosstalk. While previous studies suggest an association between CVMs and NTDs, the exact mechanism underlying this relationship remains unclear. In this review, we explore embryonic development, signalling pathways and clinical phenotypes involved in the association between CVMs and NTDs. Moreover, we provide a summary of syndromes that exhibit occurrences of both CVMs and NTDs. We aim to provide insights into the potential mechanisms underlying the association between CVMs and NTDs, thereby facilitating clinical diagnosis and management of these anomalies.

PURPOSE OF REVIEW: Osteoarthritis (OA) is a prevalent and debilitating condition characterized by joint degeneration and pain. Current treatment options aim to alleviate symptoms and slow disease progression but lack curative potential. Stem cell therapies have emerged as a promising alternative. This article explores the epidemiology, pathophysiology, clinical manifestations of hip and knee OA, and the evolving role of stem cell therapies in their treatment. RECENT FINDINGS: The global prevalence of OA, with knee OA being the most common form, has fueled the demand for stem cell therapies. Despite limited robust evidence supporting their efficacy, clinical trials investigating stem-cell treatments for OA have reported encouraging radiological and clinical improvements. Stem cell therapies offer potential disease-modifying benefits through immunomodulatory actions, growth factor secretion, and chondrogenic capabilities. Adipose-derived mesenchymal stem cells (ADMSCs) have shown promise in clinical trials for OA treatment, offering potential pain relief and functional improvement. ADMSCs possess advantages such as accessibility and a favorable safety profile, making them a viable option for OA management. Although other stem-cell types, including human embryonic stem cells (hESCs) and induced pluripotent stem cells (iPSCs), have been used in OA treatment, ADMSCs have demonstrated superior outcomes. By providing a comprehensive overview of the evolving landscape of stem cell therapies for hip and knee OA, this article highlights the potential of stem-cell treatments to address the limitations of current therapies. However, further research is required to establish their long-term efficacy, identify optimal stem-cell types, and develop standardized protocols.

INTRODUCTION: Flexor tenosynovitis (FTS) is a deep space infection of an upper extremity digit which carries a high rate of morbidity. OBJECTIVE: This review highlights the pearls and pitfalls of FTS, including presentation, diagnosis, and management in the emergency department (ED) based on current evidence. DISCUSSION: FTS typically occurs after direct penetrating trauma to the volar aspect of an upper extremity digit. Development of a deep space infection that quickly propagates through the flexor tendon sheath of a digit can result in serious structural damage to the hand and place the patient at risk for significant morbidity such as finger amputation or even result in death. Signs of FTS include symmetrical swelling of the affected finger, the affected finger being held in a flexed position, pain on any attempt of passive finger extension, and tenderness along the course of flexor tendon sheath, known as the Kanavel signs. Systemic symptoms such as fevers and chills may occur. Recognition of these signs and symptoms is paramount in diagnosis of FTS, as laboratory and imaging assessment is not typically diagnostic. ED management involves intravenous antibiotics and emergent surgical specialist consultation. CONCLUSION: An understanding of the presentation and risk factors for development of FTS can assist emergency clinicians in diagnosing and managing this disease in an expedited fashion.

PURPOSE: Patients with COVID-19 undergoing hip fracture surgeries have a 30-day mortality of up to 34%. We aimed to evaluate the association between anesthesia technique and 30-day mortality after hip fracture surgery in patients with COVID-19. METHODS: After ethics approval, we performed a retrospective cohort analysis of the American College of Surgeons National Surgical Quality Improvement Program data set from January to December 2021. Inclusion criteria were age ≥ 19 yr, laboratory-confirmed SARS-CoV-2 infection within 14 days preoperatively, and hip fracture surgery under general anesthesia (GA) or spinal anesthesia (SA). Exclusion criteria were American Society of Anesthesiologists Physical Status V, ventilator dependence, international normalized ratio ≥ 1.5, partial thromboplastin time > 35 sec, and platelet count < 80 × 109 L-1. The primary outcome was all-cause 30-day mortality. The adjusted association between anesthetic technique and 30-day mortality was analyzed using multivariable logistic regression. RESULTS: Of 23,045 patients undergoing hip fracture surgery, 331 patients met the study criteria. The median [interquartile range] age was 82 [74-88] yr, and 32.3% were male. The 30-day mortality rate was 10.0% (33/331) for the cohort (10.7%, 29/272 for GA vs 6.8%, 4/59 for SA; P = 0.51; standardized mean difference, 0.138). The use of SA, compared with GA, was not associated with decreased mortality (adjusted odds ratio, 0.61; 95% confidence interval, 0.21 to 1.8; E-value, 2.49). CONCLUSION: Anesthesia technique was not associated with mortality in patients with COVID-19 undergoing hip fracture surgery. The findings were limited by a small sample size.

RéSUMé: OBJECTIF: Les personnes atteintes de COVID-19 bénéficiant d'une chirurgie de fracture de la hanche ont une mortalité à 30 jours allant jusqu'à 34 %. Notre objectif était d'évaluer l'association entre la technique d'anesthésie et la mortalité à 30 jours après une chirurgie de fracture de la hanche chez les personnes atteintes de COVID-19. MéTHODE: Après l'approbation du comité d'éthique, nous avons réalisé une analyse de cohorte rétrospective de l'ensemble de données du Programme national d'amélioration de la qualité chirurgicale de l'American College of Surgeons de janvier à décembre 2021. Les critères d'inclusion étaient un âge ≥ 19 ans, une infection par le SRAS-CoV-2 confirmée en laboratoire dans les 14 jours préopératoires et une chirurgie de fracture de la hanche sous anesthésie générale (AG) ou rachianesthésie (RA). Les critères d'exclusion étaient un statut physique V selon l'American Society of Anesthesiologists, la dépendance à une assistance ventilatoire, un ratio international normalisé ≥ 1,5, un temps de thromboplastine partielle > 35 sec, et une numération plaquettaire < 80 × 109 L−1. Le critère d'évaluation principal était la mortalité à 30 jours toutes causes confondues. L'association ajustée entre la technique anesthésique et la mortalité à 30 jours a été analysée à l'aide d'une régression logistique multivariée. RéSULTATS: Sur 23 045 patient·es opéré·es pour une fracture de la hanche, 331 répondaient aux critères de l'étude. L'âge médian (écart interquartile) était de 82 [7488] ans et 32,3 % étaient des hommes. Le taux de mortalité à 30 jours était de 10,0 % (33/331) pour la cohorte (10,7 %, 29/272 pour l'AG vs 6,8 %, 4/59 pour la RA; P = 0,51; différence moyenne standardisée, 0,138). L'utilisation de la RA, par rapport à l'AG, n'a pas été associée à une diminution de la mortalité (rapport de cotes ajusté, 0,61; intervalle de confiance à 95 %, 0,21 à 1,8; valeur E, 2,49). CONCLUSION: La technique d'anesthésie n'a pas été associée à la mortalité chez les personnes atteintes de COVID-19 bénéficiant d'une chirurgie de fracture de la hanche. Les résultats ont été limités par la petite taille de l'échantillon. ENREGISTREMENT DE L'éTUDE: www.ClinicalTrials.gov (NCT05133648); enregistrée le 24 novembre 2021.

BACKGROUND: The modified Gartland classification is the most widely accepted grading method of supracondylar humeral fractures among orthopedic surgeons and is relevant to identifying fractures that may require surgery. OBJECTIVE: To assess the interobserver reliability of the modified Gartland classification among pediatric radiologists, pediatric orthopedic surgeons, and pediatric emergency medicine physicians. MATERIALS AND METHODS: Elbow radiographs for 100 children with supracondylar humeral fractures were retrospectively independently graded by two pediatric radiologists, two pediatric orthopedic surgeons, and two pediatric emergency medicine physicians using the modified Gartland classification. A third grader of the same subspecialty served as a tie-breaker as needed to reach consensus. Readers were blinded to one another and to the medical record. The modified Gartland grade documented in the medical record by the treating orthopedic provider was used as the reference standard. Interobserver agreement was assessed using kappa statistics. RESULTS: There was substantial interobserver agreement (kappa = 0.77 [95% CI, 0.69-0.85]) on consensus fracture grade between the three subspecialties. Similarly, when discriminating between Gartland type I and higher fracture grades, there was substantial interobserver agreement between specialties (kappa = 0.77 [95% CI, 0.66-0.89]). The grade assigned by pediatric radiologists differed from the reference standard on 15 occasions, pediatric emergency medicine differed on 19 occasions, and pediatric orthopedics differed on 9 occasions. CONCLUSION: The modified Gartland classification for supracondylar humeral fractures is reproducible among pediatric emergency medicine physicians, radiologists, and orthopedic surgeons.

PURPOSE: To explore whether it is necessary to put drain tubes after posterior pedicle screw fixation of thoracolumbar fractures. METHODS: From April 2020 to January 2023, a total of 291 patients with recent thoracolumbar fractures (AO type-A or type-B) who received the pedicle screw fixation operation were enrolled retrospectively. In 77 patients, drain tubes were used in the pedicle screw fixation surgery, while no drain tubes were placed in the other group. After gleaning demographic information and results of lab examination and imageology examination, all data were put into a database. Independent-sample t-tests, Pearson Chi-Square tests, Linear regression analysis, and correlation analysis were then performed. RESULTS: Compared to the control group, the drainage group had significantly lower postoperative CRP levels (P = 0.047), less use of antipyretics (P = 0.035), higher ADL scores (P = 0.001), and lower NRS scores (P < 0.001) on the 6th day after surgery. Other investigation items, such as demographic information, operation time, intraoperative blood loss, body temperature, and other preoperative and postoperative lab results, showed no significant differences. CONCLUSIONS: The use of a drain tube in the pedicle screw fixation of thoracolumbar fractures is correlated with the improvement of patients' living and activity ability and the reduction of inflammation, postoperative fever and pain.

Orthopaedic and sports medicine clinicians can improve outcomes for transgender patients by understanding the physiological effects of gender-affirming hormone therapy (GAHT). This narrative review investigated the role of GAHT on bone mineral density, fracture risk, thromboembolic risk, cardiovascular health and ligament/tendon injury in this population. A search from the PubMed database using relevant terms was performed. Studies were included if they were levels 1-3 evidence. Due to the paucity of studies on ligament and tendon injury risk in transgender patients, levels 1-3 evidence on the effects of sex hormones in cisgender patients as well as basic science studies were included for these two topics. This review found that transgender patients on GAHT have an elevated fracture risk, but GAHT has beneficial effects on bone mineral density in transgender women. Transgender women on GAHT also have an increased risk of venous thromboembolism, stroke and myocardial infarction compared with cisgender women. Despite these elevated risks, studies have found it is safe to continue GAHT perioperatively for both transgender women and men undergoing low-risk operations. Orthopaedic and sports medicine clinicians should understand these unique health considerations for equitable patient care.
RESUMO
BACKGROUND: ChatGPT is a natural language processing model developed by OpenAI, which can be iteratively updated and optimized to accommodate the changing and complex requirements of human verbal communication. OBJECTIVE: The study aimed to evaluate ChatGPT's accuracy in answering orthopedics-related multiple-choice questions (MCQs) and assess its short-term effects as a learning aid through a randomized controlled trial. In addition, long-term effects on student performance in other subjects were measured using final examination results. METHODS: We first evaluated ChatGPT's accuracy in answering MCQs pertaining to orthopedics across various question formats. Then, 129 undergraduate medical students participated in a randomized controlled study in which the ChatGPT group used ChatGPT as a learning tool, while the control group was prohibited from using artificial intelligence software to support learning. Following a 2-week intervention, the 2 groups' understanding of orthopedics was assessed by an orthopedics test, and variations in the 2 groups' performance in other disciplines were noted through a follow-up at the end of the semester. RESULTS: ChatGPT-4.0 answered 1051 orthopedics-related MCQs with a 70.60% (742/1051) accuracy rate, including 71.8% (237/330) accuracy for A1 MCQs, 73.7% (330/448) accuracy for A2 MCQs, 70.2% (92/131) accuracy for A3/4 MCQs, and 58.5% (83/142) accuracy for case analysis MCQs. As of April 7, 2023, a total of 129 individuals participated in the experiment. However, 19 individuals withdrew from the experiment at various phases; thus, as of July 1, 2023, a total of 110 individuals accomplished the trial and completed all follow-up work. After we intervened in the learning style of the students in the short term, the ChatGPT group answered more questions correctly than the control group (ChatGPT group: mean 141.20, SD 26.68; control group: mean 130.80, SD 25.56; P=.04) in the orthopedics test, particularly on A1 (ChatGPT group: mean 46.57, SD 8.52; control group: mean 42.18, SD 9.43; P=.01), A2 (ChatGPT group: mean 60.59, SD 10.58; control group: mean 56.66, SD 9.91; P=.047), and A3/4 MCQs (ChatGPT group: mean 19.57, SD 5.48; control group: mean 16.46, SD 4.58; P=.002). At the end of the semester, we found that the ChatGPT group performed better on final examinations in surgery (ChatGPT group: mean 76.54, SD 9.79; control group: mean 72.54, SD 8.11; P=.02) and obstetrics and gynecology (ChatGPT group: mean 75.98, SD 8.94; control group: mean 72.54, SD 8.66; P=.04) than the control group. CONCLUSIONS: ChatGPT answers orthopedics-related MCQs accurately, and students using it excel in both short-term and long-term assessments. Our findings strongly support ChatGPT's integration into medical education, enhancing contemporary instructional methods.

BACKGROUND: Several systematic reviews (SRs) assessing the use of telemedicine for musculoskeletal conditions have been published in recent years. However, the landscape of evidence on multiple clinical outcomes remains unclear. OBJECTIVE: We aimed to summarize the available evidence from SRs on telemedicine for musculoskeletal disorders. METHODS: We conducted an umbrella review of SRs with and without meta-analysis by searching PubMed and EMBASE up to July 25, 2022, for SRs of randomized controlled trials assessing telemedicine. We collected any kind of patient-reported outcome measures (PROMs), patient-reported experience measures (PREMs), and objective measures, including direct and indirect costs. We assessed the methodological quality with the AMSTAR 2 tool (A Measurement Tool to Assess systematic Reviews 2). Findings were reported qualitatively. RESULTS: Overall, 35 SRs published between 2015 and 2022 were included. Most reviews (n=24, 69%) were rated as critically low quality by AMSTAR 2. The majority of reviews assessed "telerehabilitation" (n=29) in patients with osteoarthritis (n=13) using PROMs (n=142 outcomes mapped with n=60 meta-analyses). A substantive body of evidence from meta-analyses found telemedicine to be beneficial or equal in terms of PROMs compared to conventional care (n=57 meta-analyses). Meta-analyses showed no differences between groups in PREMs (n=4), while objectives measures (ie, "physical function") were mainly in favor of telemedicine or showed no difference (9/13). All SRs showed notably lower costs for telemedicine compared to in-person visits. CONCLUSIONS: Telemedicine can provide more accessible health care with noninferior results for various clinical outcomes in comparison with conventional care. The assessment of telemedicine is largely represented by PROMs, with some gaps for PREMs, objective measures, and costs. TRIAL REGISTRATION: PROSPERO CRD42022347366; https://osf.io/pxedm/.

Recognizing and addressing the controversies surrounding using patient-reported outcome measures (PROMs) is crucial for enhancing evaluation standards in clinical studies in orthopedics, sports medicine, and rehabilitation. The article comprehensively described the challenges of using PROMs to evaluate knee conditions in these fields. Apart from defining and characterizing patient-reported outcomes and their measures, the article discussed controversies around them, such as using them as primary outcomes. It highlighted the importance of standardizing and validating PROMs. Several initiatives taken to improve the selection of appropriate outcomes for clinical research purposes were described. Additionally, the potential of technology, mainly digital health tools and mobile applications, was mentioned in the context of enhancing the collection and analysis of PROMs. The article also raised the issue of the readability of PROMs, defined as the ease with which they can be read and understood by patients. The article concluded that adopting a complementary approach to treatment evaluation by integrating subjective and objective measures is imperative for accurately assessing efficacy. This comprehensive approach provides a more holistic understanding of patient outcomes, forms the foundation for evidence-based medicine, and informs future healthcare policies. Proactive measures are urgently needed to address concerns and improve the reliability and validity of PROMs for clinical practice and research. LEVEL OF EVIDENCE: level V.
RESUMO
BACKGROUND: During the COVID-19 pandemic, large in-person conferences were mostly cancelled to avoid further disease contagion. Physicians continued to demand changes in form to enable participation in lifelong medical education programs, and the traditional model of in-person conferences needed to be rethought. As such, a regional branch of the national orthopedic association tried to move in-person conferences onto a virtual platform. This study aimed to investigate the effect of transitioning large in-person conferences to a virtual model during the COVID-19 pandemic, especially examining any differences in the attendance of each type of conference. METHODS: In this retrospective observational study, 776 participants in virtual conferences and 575 participants in in-person conferences were analyzed. Institutions were classified based on their location in a central city and two neighboring cities. Affiliated institutions were divided into resident training hospitals, general hospitals, and private clinics. The change in the number and proportion of participants between the virtual conference year and in-person conference year was calculated. RESULTS: The number of virtual conference participants was significantly greater than that of in-person conference participants (P = 0.01). Although the highest number of participants was from central city for both years, the proportion of participants from the two neighboring cities increased. Although the proportion of participants from resident training hospitals and private clinics decreased, the proportion of participants from general hospitals increased. CONCLUSIONS: We implemented a virtual platform to tackle challenges associated with lifelong medical education during the COVID-19 pandemic. The virtual platforms can be helpful for organizations that must hold regular lifelong medical education programs for members spread across a wide geographic region.

BACKGROUND: Annually, medical students vie to secure a seat with an orthopedic residency program. This rigorous competition places orthopedic surgery as one of the most competitive specialties in the medical field. Although several international studies have been published regarding the factors that influence program directors when choosing their ideal applicant, the data for Saudi Arabia in that regard is absent. METHODS: In this cross-sectional study, we aimed to survey all orthopedic program directors regarding the factors that influence them when choosing their ideal orthopedic surgery applicant. A survey was sent to all program directors via email during the month of August 2022. A reminder was sent 2 weeks later to maximize the response rate. The survey was completed by 22 out of 36 orthopedic program directors, which gave us a response rate of 61.11%. RESULTS: In this study, 22 orthopedic surgery program directors responded to our survey. When program directors were asked to rank the factors of residency selection criteria, the top ranked factors were good impression on interviews; prior experience in orthopedic surgery with, for example, electives; and performance on ethical questions during interviews, with means of 9.18, 8.95, and 8.82 out of 10, respectively. Furthermore, program directors preferred letters of recommendation from recommenders that they personally know, clinical experience such as electives taken at the program director's institution, and the quality of publications as the most important aspects of research. Most program directors (90.9%) relied on their residents' and fellows' opinions when selecting candidates, and 77.3% did not think gender has an influence on selection of applicants. CONCLUSION: By providing comprehensive data regarding the factors that influence and attract program directors of orthopedic surgery when choosing residency candidates. With the data provided by this study, applicants for orthopedic surgery have the advantage of early planning to build a strong application that may help persuade program directors to choose them.
