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.
Background: The aim of this study was to create AO 44 A1, B1 and C1 fractures using finite element analysis (FEA), to determine the stability of k-wire, intramedullary screw (IS) and plate-screw (PS) fixation methods in fracture
Methods: Using FEA the post-reduction behaviour of AO 44 A1, B1 and C1 fractures with k-wire, IS and PS fixation methods was analysed and compared in terms of displacement and stress.
Results: The lowest amount of displacement was provided with the IS method in AO 44 A1 and B1. It was observed in the detection of 4 mm k-wire in AO 44 C1. The total displacement of the IS system used for fixation in AO 44 A1, B1 and C1 fractures was lower
Conclusions: According to FEA results, the lowest amount of displacement was obtained with IS in AO 44 A1 and B1, while 4 mm K-wire fixation was achieved in AO 44 C1 fractures.
Background: Distal fibula fractures at the ankle level are common and are usually accompanied by ligament injuries. This study aims to evaluate the effects of ankle ligament ruptures on ankle joints, fracture instability, and plate stress after distal fibula fracture fixed with plate created by finite element analysis (FEA) modeling and loading applied to ligament rupture models that may accompany this fracture.
Methods: A finite element model consisting of 3-D (3D) fibula, tibia, foot bones, and ankle ligaments was designed to investigate the effects of ligament injuries accompanying plate-detected Arbeitsgemeinschaft für Osteosynthesefragen (AO 44B2.1)-type fractures on fracture detection, fixation material, and ankle joints. Then, the results were evaluated by modeling ligament rupture in 6 different ways.
Results: In the modeling where the deltoid and the talofibular ligament are broken together, instability is the highest in the ankle (2.31 mm) and fracture line (0.15 mm). In our study, the rupture of the tibiofibular anterior and posterior ligaments associated with syndesmosis caused less instability in the fracture and ankle than the single rupture models of both the deltoid and the talofibular ligament.
Conclusions: In the finite element modeling of AO 44B2.1-type fractures detected with plate, the importance and potential effects of often overlooked ankle ligaments are pointed out shown. It is important to keep in mind that when treating ankle injuries, the ankle should be treated as a whole, with both bone and soft tissue. In some cases, the fracture may represent the visible tip of the iceberg.
Background: This study aimed to compare two-point discrimination in feet with ankle sprains and feet without ankle problems, and to determine whether there was a change in the two-point discrimination values in ankle sprains.
Methods: A total of 108 people were included in the study. These subjects were aged between 18 and 40 years and visited the Medical Faculty of Yozgat Bozok University for various reasons in July and September of 2022. These people were divided into two groups: subjects with an ankle sprain and subjects with no ankle problems. Two-point discrimination values measured in mm were recorded for both groups using a caliper (esthesiometer) used in six regions of 216 feet. The two-point discrimination threshold values of the feet were compared statistically according to feet with ankle sprains and feet without ankle problems, as well as in right and left feet.
Results: The study determined that the two-point discrimination threshold values measured at the 1st toe tip, heel, 3rd plantar metatarsal head, medial malleolus, and lateral malleolus in subjects with an ankle sprain was higher than in subjects with no ankle problems. When comparing both feet of the subjects with an ankle sprain, the two-point discrimination threshold value in the heel of the foot with an ankle sprain was higher than in the heel of the foot without ankle problems.
Conclusions: The two-point discrimination threshold value was higher in subjects with an ankle sprain than in subjects with no ankle problems. The data suggest that the two-point discrimination threshold may be higher in people with an ankle sprain. Further studies are needed to better understand the two-point discrimination threshold in ankle sprains.
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.
