In this study, it was aimed to determine the quality and accuracy of the videos on YouTube about lateral epicondylitis. MethodsThe first 100 videos were included in the study by typing the keyword "lateral epicondylitis" in the YouTube search tab without using any filters. The video power index (VPI) was used to evaluate the popularity of the videos, and the global quality score (GQS), Journal of the American Medical Association (JAMA), and DISCERN scoring systems were used to evaluate the quality. The obtained data were statistically analyzed according to these scoring systems. ResultsThe mean DISCERN, JAMA, and GQS of the analyzed videos were 46.66, 3.13, and 3.85, respectively. According to these results, it was determined that the videos were of medium quality. A statistically insignificant and weak correlation was found between the VPI and DISCERN, GQS, and JAMA scores (p>0.05, intraclass correlation coefficient, ICC: −0.05, 0.09, and −0.05, respectively). While there was no significant relationship between the video source and the DISCERN, JAMA, and GQS scores (p>0.05), it was determined that the DISCERN, JAMA, and GQS scores in the exercise videos were significantly higher than in the other content types in terms of the video content (p=0.041). ConclusionsAccording to the results obtained, it was determined that YouTube videos about lateral epicondylitis were not of sufficient quality. In order to ensure standardization for quality videos, internationally acceptable guidelines should be determined and studies should be carried out to provide an adequate infrastructure for the preparation of quality medical videos that can meet the increasing needs of patients by health institutions.

This study aims to determine the gender differences in hip joint functional anthropometric measurement values in Turkish adults. Materials and Methods: Digital pelvis anteriorposterior radiographs of 300 randomly selected patients were analyzed. In these radiographs, reference lines were drawn and femoral neck-shaft angle (NSA), hip rotation center (HRC), abductor moment arm (AMA), body weight moment arm (BMA) were calculated. The relationship of the distribution of measurement results with gender and age was examined. Results: It was determined that the mean NSA scores in men were significantly higher than in women (p<0.05). It was determined that AMA value was significantly higher in men and BMA value was significantly higher in women (p<0.05). BMA/AMA ratio was found to be statistically significantly higher in women (p<0.005). Conclusion: Statistically significant differences were found between men and women in the mean of AMA, BMA and BMA/AMA in the Turkish population.

Background: Our aim in this study is to investigate the role of Doppler ultrasonography (DUS) in the localization of obstruction in the arterial system in patients who underwent lower extremity amputation due to diabetic foot, and to compare the sensitivity, specificity and accuracy of DUS compared to computed tomography angiography (CTA). Materials and Method: Patients who underwent lower extremity amputation due to diabetic foot between 2018 and 2020 were evaluated retrospectively. 102 patients with both DUS and CTA imaging before the first amputation were included in the study. The stenosis and occlusion data detected in the vessel segments in both imaging modalities were analyzed statistically and the sensitivity, specificity and accuracy of DUS according to CTA were determined. Results: Of 102 patients, 92 (90.2%) were male and 10 (9.8%) were female. The mean age was 67.23±1.06 (range: 39-87 years). A total of 714 artery segments in the reamputated lower extremity were visualized with both DUS and CTA. When all segments were examined, 211 (29.4%) stenosis and 245 (34%) occlusion were detected in CTA, while 269 (37.4%) stenosis and 109 (15.1%) occlusions were detected in DUS. The results obtained as a result of the statistical evaluation performed to determine the sensitivity, specificity and accuracy of DUS compared to CTA were 87.93%, 91%, and 88.77%, respectively. Conclusion:According to this study, DUS is a safe and non-invasive method for investigating the lower extremity arterial system. We think that it is a method that can be preferred as an alternative to CTA, which is especially performed by experienced radiologists.
