Abstract
Background: The aim of this study is to measure the quality of information about ‘flatfoot’ and ‘pes planus’ presented online on the social media site YouTube and to determine the trends of viewers to medical information on YouTube.
Methods: ‘flatfoot and pes planus’ was typed into the YouTube search module. From the search results, videos with 50000 views or more, longer than 45 seconds, containing information about flatfoot and pes planus disease were selected. DISCERN, JAMA scoring, daily average views, number of likes, number of comments were collected from 53 videos that met the criteria. The profession of the sharer was evaluated in terms of the information quality of the sharing and the orientation of the audience.
Results: The mean number of views per day of the examined videos was 2047. Mean video presentation time was 8 minutes 50 seconds. The mean JAMA score was 2/4 and the mean DISCERN score was 38.16/75. According to the DISCERN score according to the professions, the video quality was moderate in doctors (41.44±12.99), moderate in physiotherapists (41.91±9.04), poor in coaches (32.78±7.87), poor in patients (34.50±5.32) and weak in others (34.89±14.00). According to the Spearman correlation between DISCERN score and mean daily viewing significant relationships were found in the doctors group p:0.0102 and the others group p:0.0033, however, no significant relationships were observed in the physiotherapists group p:0.1073, the flatfoot patients group p:0.5363 and the coaches group p:0.9111. There were significant relationships between like and comment counts in all groups (doctors p:0.0088, coaches p:0.0069, physiotherapists p:0.0007, others p:0.0018, patients p:0.0066).
Conclusions: Looking at previous studies, it was observed that the quality of online health information was historically inadequate. Likewise, in our study on YouTube, we found that the quality of flatfoot and pes planus information was poor to moderate.
Abstract
Background: Distal osteotomy of the first metatarsal is a widely used method for the correction of mild-to-moderate hallux valgus deformities. The objective of this study was to compare the stability of headless compression screws, kirschner wires and absorbable pins in terms of stiffness and maximum load in distal oblique metatarsal osteotomy.
Methods: A total of 30 4th generation first metatarsal synthetic bone models were divided into three groups according to the fixation techniques. The stiffness of the first metatarsal was calculated as the slope of the linear curve that fit with the first linear part of the force displacement curve. The failure strength was recorded as the maximum load. The stiffness and maximum load values in the axillary and transverse configurations were compared between the three fixation groups.
Results: The stiffness was statistically higher in Group K and Group C compared to Group B in both axial and transverse loading. Similarly, the maximum load was significantly higher in both Group K and Group C compared to Group B in both loading conditions. No significant difference was found between Group K and Group C in stability. The higher failure strength was obtained with headless compression screws (113.34±35.88 N) in the axial loading. The lowest failure strength was found in the absorbable pins technique (16.17±7.72 N) in the transverse loading.
Conclusion: No significant difference was found between the Kirschner wires and headless compression screws techniques, although the highest strength was obtained with headless compression screws that are increasingly used in orthopedic practice.
