RESUMO
Purpose: This study seeks to assess the quality and reliability of YouTube videos on Dupuytren's contracture. Methods: The first 50 unique videos on Dupuytren's contracture were evaluated by searching YouTube for Dupuytren's contracture. Video metrics, source, and content type were recorded. Video reliability was assessed using the Journal of American Medical Association (JAMA) Benchmark criteria. Video educational quality was assessed using the Global Quality Score (GQS) and a Dupuytren's Contracture-Specific Score (DC-SS). Results: The total number of views for all 50 videos evaluated was 1,908,608 (mean, 38,172.16 ± 5,502.45 views). The mean reliability (JAMA) score was 2.21 ± 0.69 (range 0-4), the mean educational quality (GQS) score was 2.80 ± 1.28 (range 1-5), and the mean disease-specific (DC-SS) score was 6.05 ± 2.17 (range 0-15). Nonphysician health care professionals had the most popular videos, but the lowest DC-SS. GQS varied based on the video source, with physician-uploaded videos having the highest average quality scores. Physician source was an independent positive predictor of higher quality (GQS) (ß = 0.477). Conclusions: Videos on Dupuytren's contracture were frequently viewed on YouTube but had overall low educational quality and reliability. Of the videos that discussed collagenase as a treatment option, 40% failed to mention percutaneous needle aponeurotomy. Patients may be exposed to an incomplete set of treatment options. Educational content on YouTube should be interpreted cautiously and proper in-office education and high-quality resources for Dupuytren's contracture should be provided by physicians. Type of Study/Level of Evidence: Therapeutic IV.
RESUMO
Purpose: Distal radioulnar joint (DRUJ) injuries can be devastating and challenging to manage. The multiplanar curvature exhibited by the ulna impacts the morphology of the DRUJ, making it difficult to assess through two-dimensional radiographs alone. We used full-length, three-dimensional (3D) computed tomography angiography scans to assess the relationship between ulnar bowing, DRUJ ulnar variance (UV), and sigmoid notch angle. The goal of this study was to establish normal anatomic ranges for these landmarks to improve treatment for forearm traumas and DRUJ pathologies. Methods: Eighty-two intact upper extremity computed tomography angiography scans were examined and reconstructed into 3D models. We characterized ulnar bowing and DRUJ metrics using computer-aided design software. Measures of central tendency and Pearson correlation coefficients were calculated for comparative analysis. Results: The study yielded an average ulnar length of 272.3 mm. We identified the proximal ulnar bow at 36.7% of the bone's total length, possessing a depth of 10.3 mm, a proximal angle of 6.6°, and a distal angle of 3.9°. The distal ulnar bow appeared at 75.3% of the bone's length, characterized by a depth of 4.2 mm, a proximal angle of 2°, and a distal angle of 4.3°. In the coronal plane, the proximal angle of the proximal ulnar bow correlated positively with UV (r = 0.39, P < .001), whereas the distal angle of the distal ulnar bow correlated negatively (r = -0.48, P < .001). We also found significant correlations between the depths of both proximal and distal bows with UV (r = 0.38, P < .001; r = -0.34, P < .001, respectively). Moreover, UV within the DRUJ strongly correlated with the sigmoid notch angle (r = -0.77, P = .01). In contrast, the sagittal plane metrics did not show meaningful correlations with UV. Conclusion: Sagittal alignment and translation at the DRUJ articulation are directly related to ulna bowing at the distal ulna. A nuanced understanding of these 3D relationships can enhance preoperative planning when correcting ulnar-side pathology. Type of study/level of evidence: Therapeutic IV.
RESUMO
Background: Medical school clerkship grades are used to evaluate orthopedic surgery residency applicants, however, high interinstitutional variability in grade distribution calls into question the utility of clerkship grades when evaluating applicants from different medical schools. This study aims to evaluate the variability in grade distribution among medical schools and look for trends in grade distribution over recent years. Methods: Applications submitted to Rush University's orthopedic surgery residency program from 2015, 2019, and 2022 were collected from the Electronic Residency Application Service. Applications from the top 100 schools according to the 2023-2024 U.S. News and World Report Research Rankings were reviewed. The percentage of "honors" grades awarded by medical schools for the surgery and internal medicine clerkships were extracted from applicants' Medical Student Performance Evaluation letters. Results: The median percentage of honors given in 2022 was 36.0 % (range 10.0-82.0) for the surgery clerkship and 33.0 % (range 6.7-80.0) for the internal medicine clerkship. Honors were given 6.6 % more in the surgery clerkship in 2022 compared to 2015. There was a negative correlation between a higher (worse) U.S. News and World Report research ranking and the percentage of honors awarded in 2022 for the surgery and internal medicine clerkships. Conclusion: There is substantial interinstitutional variability in the rate that medical schools award an "honors" grade with evidence of grade inflation in the surgery clerkship. Residency programs using clerkship grades to compare applicants should do so cautiously provided the variability demonstrated in this study.
