Abstract Deep learning is revolutionizing medical imaging analysis by enabling the classification of various pathoanatomical conditions at scale. Unfortunately, there have been a limited number of accurate and efficient machine learning (ML) algorithms that have been developed for the diagnostic workup of morphological hip pathologies, including developmental dysplasia of the hip and femoroacetabular impingement. The current study reports on the performance of a novel ML model with YOLOv5 and ConvNeXt-Tiny architecture in predicting the morphological features of these conditions, including cam deformity, ischial spine sign, dysplastic appearance, and other abnormalities. The model achieved 78.0% accuracy for detecting cam deformity, 87.2% for ischial spine sign, 76.6% for dysplasia, and 71.6% for all abnormalities combined. The model achieved an Area under the Receiver Operating Curve of 0.89 for ischial spine sign, 0.80 for cam deformity, 0.80 for dysplasia, and 0.81 for all abnormalities combined. Inter-rater agreement among surgeons, assessed using Gwet’s AC1, was substantial for dysplasia (0.83) and all abnormalities (0.88), and moderate for ischial spine sign (0.75) and cam deformity (0.61).

Purpose To use the All of Us database to investigate barriers to health care access for patients with meniscus tears and to examine how specific demographic, socioeconomic, and health‐related factors independently influence their health care utilization. Methods The National Institutes of Health All of Us database was queried for patient data between March 2017 and March 2023 to form a cohort of patients with meniscal tears. Patients with meniscal tears were identified using Systematized Nomenclature of Medicine clinical terms. All patients with self‐reported meniscus tears were included, with no exclusion criteria to ensure a diverse representation of underrepresented individuals. Patient responses to the “Healthcare Access and Utilization Survey” were analyzed across 4 domains: “delayed care,” “could not afford care,” “skipped medication,” and “have not seen a provider in over one year.” Results In total, 5,671 survey respondents with meniscal tears were included for analysis from a population of 436,000 eligible records. Among them, 27.7% reported delayed care, 23.9% were unable to afford care, 11.8% skipped medication, and 2.0% had not seen a provider in over a year. Patients with annual incomes under $50,000 were more likely to delay care (odds ratio [OR], 1.41; P < .001), be unable to afford care (OR, 1.73; P < .001), or skip medications (OR, 1.79; P < .001). Younger age than the cohort mean of 65.4 years, female sex, and poor physical and mental health were associated with impaired access in at least 1 care domain. Conclusions Over one‐fourth of patients with a diagnosis of meniscus tear who responded to the All of Us “Healthcare Access and Utilization Survey” reported difficulties with access to care across 4 domains, with those of low income, younger age, female sex, and poor mental or physical health experiencing significant barriers to care. Clinical Relevance This research can inform strategies for equitable treatment of meniscal injuries by highlighting disparities in orthopaedic care access and utilization.

BACKGROUND Previous epidemiologic studies of autoimmune diseases in the US have included a limited number of diseases or used metaanalyses that rely on different data collection methods and analyses for each disease. METHODS To estimate the prevalence of autoimmune diseases in the US, we used electronic health record data from 6 large medical systems in the US. We developed a software program using common methodology to compute the estimated prevalence of autoimmune diseases alone and in aggregate that can be readily used by other investigators to replicate or modify the analysis over time. RESULTS Our findings indicate that over 15 million people, or 4.6% of the US population, have been diagnosed with at least 1 autoimmune disease from January 1, 2011, to June 1, 2022, and 34% of those are diagnosed with more than 1 autoimmune disease. As expected, females (63% of those with autoimmune disease) were almost twice as likely as males to be diagnosed with an autoimmune disease. We identified the top 20 autoimmune diseases based on prevalence and according to sex and age. CONCLUSION Here, we provide, for what we believe to be the first time, a large-scale prevalence estimate of autoimmune disease in the US by sex and age.

Background: Managing an in-season anterior shoulder instability poses a special challenge for team physicians, as they need to balance the aim of promptly returning the athlete to play while mitigating the chances of recurrence and further injury to the shoulder. Purpose: To investigate and report on the treatment preferences of National Hockey League (NHL) team physicians when managing in-season first-time anterior shoulder instability in professional hockey players. Study Design: Cross-sectional study. Methods: A survey consisting of 33 sport-specific questions focused on the treatment options and preferences for anterior shoulder instability in hockey players was developed, and 32 NHL team physicians were invited to anonymously complete the survey. Following the collection of the data, the distribution of the responses to each question was documented as counts and percentages. Results: Of the 32 invited team physicians, 31 (97%) completed all (n = 28) or most (n = 3) of the survey. The mean experience of the respondents was 13 ± 11 years. A total of 28 (90%) respondents would attempt nonoperative treatment of an in-season initial anterior shoulder dislocation with an isolated soft tissue injury, while 28 (90%) would recommend operative treatment of the same injury with bony involvement. Of the 31 respondents, 30 (97%) utilized rehabilitation parameters rather than time from injury when determining whether a player could return to play. Of those parameters, clinical strength (100%), range of motion (87%), anterior apprehension (84%), and pain (65%) were the most utilized. For surgical management of an isolated soft tissue lesion, 28 (90%) of the respondents preferred arthroscopic repair, while 2 (7%) preferred open repair. Conclusion: Of the 32 NHL team physicians surveyed, 28 preferred nonoperative management for the treatment of initial anterior shoulder dislocations with isolated soft tissue injuries, while initial operative management was preferred by the same number of team physicians for any injuries with bony involvement.
