    Biomechanical Effect of Ankle Ligament Injury in AO Type 44B2.1 Lateral Malleolus Fractures After Lateral Plate Fixation A Finite Element Analysis
    (Amer Podiatric Med Assoc, 2024) Olcar, Haci Ali; Mutu, Halil Burak; Ozer, Alaettin; Kuru, Tolgahan; Aydin, Davut; Korkmaz, Murat
    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 a plate created by finite element analysis modeling and loading applied to ligament rupture models that may accompany this fracture. Methods: A finite element model consisting of three-dimensional fibula, tibia, foot bones, and ankle ligaments was designed to investigate the effects of ligament injuries accompanying plate-detected AO type 44B2.1 fractures on fracture detection, fixation material, and ankle joints. Then, the results were evaluated by modeling ligament rupture in six different ways. Results: In the modeling where the deltoid and talofibular ligaments are broken together, instability is highest in the ankle (2.31 mm) and fracture line (0.15 mm). The rupture of the anterior and posterior tibiofibular ligaments associated with syndesmosis caused less instability in the fracture and ankle than the single-ligament rupture models of both the deltoid and talofibular ligaments. Conclusions: In the finite element modeling of AO type 44B2.1 fractures detected with plate, the importance and potential effects of often-overlooked ankle ligament injuries are pointed out. Note 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.

    Computational Mechanical Analysis of AO 44A1, 44B1, and 44C1 Fractures with Finite Element Modeling: Evaluation of Screw, Plate, and Kirschner Wire Fixation
    (Amer Podiatric Med Assoc, 2024) Olcar, Haci Ali; Ozer, Alaettin; Mutu, Halil Burak; Yurdakul, Goker; Kuru, Tolgahan; Aydin, Davut; Korkmaz, Murat
    Background: The aim of this study was to create AO 44A1, 44B1, and 44C1 fractures using finite element analysis to determine the stability of Kirschner wire, intramedullary screw, and plate-screw fixation methods in fracture. Methods: Using finite element analysis, the postreduction behavior of AO 44A1, 44B1, and 44C1 fractures with Kirschner wire, intramedullary screw, and plate-screw fixation methods was analyzed and compared in terms of displacement and stress. Results: The lowest amount of displacement was provided with the intramedullary screw method in AO 44A1 and 44B1 fractures and with the 4-mm Kirschner wire method in AO 44C1 fractures. The total displacement of the intramedullary screw system used for fixation in AO 44A1, 44B1, and 44C1 fractures was lower. Conclusions: According to finite element analysis results, the lowest amount of displacement was obtained with intramedullary screw fixation in AO 44A1 and 44B1 fractures, and 4mm Kirschner wire fixation was achieved in AO 44C1 fractures.

    Effects of early mobilization and weight bearing on postoperative walking ability and pain in geriatric patients operated due to hip fracture: a retrospective analysis
    (Tubitak Scientific & Technological Research Council Turkey, 2020) Kuru, Tolgahan; Olcar, Haci Ali
    Background/aim: Hip fractures in older adults are associated with high morbidity, mortality, and subsequent hospital costs and decreased quality of life. The objective of this study was to evaluate geriatric patients who underwent partial prosthesis surgery following hip fracture and effects of early mobilization and weight bearing on postoperative walking ability and pain. Materials and methods: A total of 52 geriatric patients with intertrochanteric and femoral neck fractures were included in the study. Patients' service files, system records, pre- and postoperative X-rays were retrospectively reviewed. Results: There were 52 patients in the study group with 36 (69.2%) being female. The mean age of the patients was found as 82.9 +/- 6.5 years. The mean length of stay in hospital was found as 6.2 +/- 2.6 days. The mean length of stay in hospital was found as 5.3 +/- 1.7 days in male and 6.6 +/- 2.8 days in female patients, and the difference was statistically significant (P = 0.035). The mean length of stay in hospital was found as 5.4 +/- 1.8 days in early mobilization group and 6.9 +/- 2.9 days in late mobilization group, and the difference was statistically significant (P = 0.026). There was a significant difference between Harris and pain scores in terms of the time of first weight bearing at the postoperative 1st month follow-up. Harris score was found as 84.0 +/- 5.8 (median: 84.0, min-max: 73-94), and the main pain score as 36.8 +/- 6.8 in the group with the first weight bearing within the first 24 h, while Harris score was found as 71.10 +/- 2.8, and the main pain score as 24.4 +/- 6.4 in the group with the first weight bearing after the postoperative 24th hour. Conclusion: The results of our study indicated that early mobilization and full weight bearing in geriatric patients after hip fracture surgery shortened length of stay in hospital, reduced postoperative pain, and increased walking ability.

    Evaluation of YouTube Information Quality About Pes Planus
    (Amer Podiatric Med Assoc, 2024) Olcar, Haci Ali; Güngör, Berna; Kuru, Tolgahan; Aydin, Davut; Nusran, Gürdal
    Background: The aim of this study was 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 50,000 views or more, longer than 45 seconds, and containing information about flatfoot and pes planus disease were selected. DISCERN and JAMA scoring, daily average views, number of likes, and 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 2,047. The mean video presentation time was 8 minutes 50 seconds. The mean JAMA score was 2 of 4 and the mean DISCERN score was 38.16 of 75. According to the DISCERN score according to the professions, the video quality was moderate for doctors (41.44 +/- 12.99), moderate for physiotherapists (41.91 +/- 9.04), poor for coaches (32.78 +/- 7.87), poor for patients (34.50 +/- 5.32), and weak for others (34.89 +/- 14.00). According to the Spearman correlation between DISCERN score and mean daily viewing, significant relationships were found for the doctors ( P = .0102) and others groups ( P = .0033); however, no significant relationships were observed for the physiotherapists group ( P = .1073), the flatfoot patients group ( P = .5363), and the coaches group ( P = .9111). There were significant relationships between like and comment counts in all groups (doctors, P = .0088; coaches, P = .0069; physiotherapists, P = .0007; others, P = .0018; and patients, P = .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. (J Am Podiatr Med Assoc 114(2), 2024; doi:10.7547/22-168)

    No Sedation, No Traction, and No Need for Assistance: Analysis of New Prakash's Method of Shoulder Reduction
    (Hindawi Ltd, 2020) Kuru, Tolgahan; Olcar, Haci Ali; Bilge, Ali; Nusran, Gurdal; Ozkilic, Recai; Akman, Canan; Prakash, Lakshmanan
    Background and Objective. Shoulder dislocations, which often occur anterior, account for about half of all dislocations. There are numerous reduction methods reported for the conservative treatment of acute anterior dislocations. However, there is still an ongoing search for an optimal method given the procedure time, possible complications, success rates, and need for sedation/analgesia in existing methods. This study seeks to explore the effectiveness and safety of Prakash's method in the treatment of acute shoulder dislocations, which is a novel method in the treatment of anterior shoulder dislocations. Materials and Methods. A total of 19 patients who were admitted to the emergency department with the diagnosis of anterior shoulder dislocation participated in this study. The diagnosis of shoulder dislocation was established in the emergency department with physical examination and anteroposterior shoulder radiography. The method was applied only once to the patients in the sitting position by the same physician without using any help, traction, anesthesia, analgesia, and myorelaxant. Results. The mean age of the patients was 37.3 +/- 13.1 years. Among them, 36.8% n=4 of the patients. The success rate of the method was 94.7% n=18. No complication was noted in the patients. The mean procedure time was 243 +/- 38 seconds. Conclusion. Prakash's method is a safe method for anterior shoulder dislocations that can be quickly performed with no need for sedation, assistance, and traction and has a high success rate.

    Original Research The biomechanical analysis of first metatarsocuneiform arthrodesis using the finite element method: A comparison of plate osteosynthesis in different positions
    (Bayrakol Medical Publisher, 2024) Olcar, Haci Ali; Ozer, Alaettin; Mutu, Halil Burak; Kuru, Tolgahan; Yurdakul, Goker; Aydin, Davut; Korkmaz, Murat
    Aim: The aim of this study was to compare plate positions in Lapidus arthrodesis in terms of displacement and plate stress. Material and Methods: In this study, the Lapidus arthrodesis was performed in a computerised environment using a finite element foot model with differentially positioned plates. The arthrodesis (Lapidus arthrodesis) was applied to the first metatarsocuneiform joint with 2 proximal 2 distal 3.5 mm screws using a 4 -hole plate in three different directions: medial, dorsal and plantar. Results: Displacement in the arthrodesis area and stress on the fixation material, the plate, were evaluated. After loading, the plantar plate arthrodesis model produced more total displacement (1, 97121 mm) and stress (2242 MPa) than other arthrodesis models. On the other hand, the dorsal plate arthrodesis model has less total displacement (1, 20479 mm) and stress (1253 MPa) than other arthrodesis models. In the volar, dorsal and medial finite element models, it was concluded that the least displacement and plate stress were in the dorsal plate application. Discussion: In the finite element study, complications can be seen more frequently in Lapidus arthrodesis performed with plantar and medial plates compared to Lapidus arthrodesis performed with dorsal plates. Therefore, Lapidus arthrodesis performed with a dorsal plate may be more stable.

    Relationship between the AB0 Blood System and Proximal Femoral Fracture Patterns in the Turkish Population
    (Hindawi Ltd, 2020) Kuru, Tolgahan; Olcar, Haci Ali
    Objective. AB0 blood groups have shown to be associated with increased risk of several orthopedic disorders such as Achilles tendon rupture and hip osteoarthritis. The objective of this study was to investigate relationships between the AB0 blood system and hip fracture patterns, duration of hospitalization, and amount of blood transfusion. Methods. Data of 308 patients treated due to hip fractures in our hospital between 2017 and 2019 were evaluated. Epicrisis reports and X-rays of the patients included in this study were retrospectively screened, and hip fractures were classified as intracapsular and extracapsular fractures. Patients were divided into A, B, 0, and AB groups according to blood groups. Results. The mean age of the patients was 75.54 +/- 13.5 years. Of all patients, 103 had an intracapsular fracture and 205 had an extracapsular fracture. No statistically significant correlation was found between blood groups and fracture patterns. No statistically significant difference was found between the amounts of transfusion according to the blood groups, and no significant difference between the durations of hospitalizations according to the blood groups. Conclusion. In our study population, we could not find a significant relationship between the AB0 blood system and fracture patterns. We think that these potential relationships could be explained with further comprehensive studies with larger populations.
