Öğe Classification of Osteophytes Occurring in the Lumbar Intervertebral Foramen(Mdpi, 2024) Tacyildiz, Abdullah Emre; Inceoglu, FeyzaBackground: Surgeons have limited knowledge of the lumbar intervertebral foramina. This study aimed to classify osteophytes in the lumbar intervertebral foramen and to determine their pathoanatomical characteristics, discuss their potential biomechanical effects, and contribute to developing surgical methods. Methods: We conducted a retrospective, non-randomized, single-center study involving 1224 patients. The gender, age, and anatomical location of the osteophytes in the lumbar intervertebral foramina of the patients were recorded. Results: Two hundred and forty-nine (20.34%) patients had one or more osteophytes in their lumbar 4 and 5 foramina. Of the 4896 foramina, 337 (6.88%) contained different types of osteophytes. Moreover, four anatomical types of osteophytes were found: mixed osteophytes in 181 (3.69%) foramina, osteophytes from the lower endplate of the superior vertebrae in 91 (1.85%) foramina, osteophytes from the junction of the pedicle and lamina of the upper vertebrae in 39 foramina (0.79%), and osteophytes from the upper endplate of the lower vertebrae in 26 (0.53%) foramina. The L4 foramen contained a significantly higher number of osteophytes than the L5 foramen. Osteophyte development increased significantly with age, with no difference between males and females. Conclusions: The findings show that osteophytic extrusions, which alter the natural anatomical structure of the lumbar intervertebral foramina, are common and can narrow the foramen.Öğe Improving the Visualization of Superior Longitudinal Fascicule-2 and Superior Longitudinal Fascicule-3 Using Photoshop Filters(Elsevier Science Inc, 2024) Tacyildiz, Abdullah Emre; Barut, Ozan; Ucer, Melih; Ozgunduz, Yaser; Bozyigit, Bulent; Tanriover, Necmettin- BACKGROUND AND OBJECTIVES: Several studies are currently exploring the anatomical origins of superior longitudinal fascicule (SLF) 2 and SLF-3, which are components of the frontoparietal network. This study aimed to achieve optimum visualization of the anatomical corridors of these fibers using Photoshop filters. - METHODS: Four postmortem brain hemispheres were dissected in accordance with the method proposed by Klingler and Ludwig. Dissections were performed under a surgical microscope (Carl Zeiss AG, Oberkochen, Germany) at 4 3 and 40 3 magnification. All dissections were documented at each stage using a professional digital camera (Canon EOS 600D) with a macro 100 mm lens (Canon), ringflash attachment (Canon), and professional tripod (Manfrotto 808 C4). We aimed to improve the visual quality of the images by avoiding monotone using various the features and filters in Photoshop . - RESULTS: SLF-2 originates from the angular gyrus (Brodmann area [BA] 39) in the right hemisphere and has been observed to project fibers from BA7 and BA19 and toward BA8, 9, 10, and 46. Further, these fibers traverse from the depths of BA40, 2, 3, 1, and 6 as they progress. SLF2 also projects fibers from the supramarginal gyrus in the left hemisphere. SLF-3 lies between the supramarginal gyrus and the inferior frontal lobe in both the right and left hemispheres. - CONCLUSIONS: The visual descriptions of the dissections were enriched after using Photoshop to avoid monotony. Increasing the visual quality with Photoshop features enable us to gain a better understanding of these pathways. Additionally, it facilitates the comprehension of the symptoms associated with pathology. We hope these results will further aid in reducing the occurrence of postoperative complications.Öğe Neurosurgical analysis of logging accidents: An observational study(Elsevier, 2021) Tacyildiz, Abdullah Emre; Akinci, Cevat; Guler, Tugba Morali; Demirkol, Hikmet; Ucer, Melih; cekmen, BoraObjective: Forestry is one of the most dangerous occupations with record high rates of accidents and mortality relative to other occupations. In the past, related studies have been conducted within the scope of occupational safety, occupational health, and public health. Clinical studies on this subject are extremely rare and not within the scope of neurosurgery. We intended to facilitate the management of logging accidents for physicians by conducting a clinical study on logging accidents. This first-of-its-kind study also aimed to comprehend the injury mechanisms in order to contribute to the efforts made to prevent injuries and to facilitate the management of these cases. Methods: The hospital records of patients who presented at the Karabuk University EAH Emergency Department owing to logging accidents between 1/1/2019 and 5/1/2020 in the Karabuk province were retrospectively analyzed. The information about patient profile, demographic information, mechanism of the logging injury, and the patterns of spinal and cranial injuries as well as other body area injuries (if any) were retrieved from the hospital records. The spinal and cranial injury patterns were analyzed from the imaging records (MRI or CT). Results: A total of 19 subjects were included in this analysis, of which 5 had cranial injury (26.3%), 2 had spinal injury (10.5%), 1 (5.2%) had both cranial and spinal injuries (this subject died in the intensive care unit at follow-up). A total of 9 (47%) subjects died. Three subjects were followed up for observation (15.7%), while 5 (26.3%) were referred to the department of orthopedics. The cranial and spinal injuries were accompanied by additional injuries such as rib fracture, hemothorax, fibula fracture, and pneumothorax. These injuries occurred in pathological conditions such as cardiac arrhythmia, facial paralysis, and epilepsy. One subject developed spinal cord damage (5.2%) that progressed to neurological shock and crash syndrome. Overall, 19 injuries occurred mainly due to 5 different mechanisms. Conclusions: The patterns of resultant spinal and cranial injuries and the related demographic information would facilitate efficient patient management. Understanding the injury mechanisms would facilitate both the management and diagnosis of such cases and the prevention of logging accidents through combined efforts of occupational safety and public health specialists.Öğe A retrospective analysis of spinal and cranial injury patterns caused by a fall from a tree in the Karabuk province(Elsevier, 2022) Tacyildiz, Abdullah Emre; Cekmen, Bora; Uzun, Ahmet; Ciftci, Temel Cevher; Uzuncu, Halil Berkay; Serdar, Sefa; Ucer, MelihIntroduction and purpose: Falling from a tree is a common cause of injury in and around the Karabuk province. Such injuries can impair the quality of life by causing permanent damage and can increase morbidity and mortality. This study aimed to reveal the patterns of spinal and cranial injuries in patients admitted to the hospital. Methods: Patients who were admitted to the emergency department after falling from a tree in the Karabuk province over a 2-year period and were diagnosed with injuries caused by falling from a tree were included. The parameters of age, sex, type of tree which the patient fell from, spinal and cranial fracture patterns and pain scores during follow-up were evaluated. Results: We studied 98 patients over a 2-year period. Of these, 5 (5.10%) patients were aged <18 and belonged to the pediatric group and 93 (94.89%) were adults. Moreover, 26 (26.53%) patients were female and 72 (73.46%) were male. The mean age of the patients was 54.4 +/- 15.78 years. Spinal injury occurred in 35 (35.71%), cranial injury in 5 (5.10%), and simple injuries to the scalp and neck in 7 (7.14%), Further, 24 (24.48%) patients had musculoskeletal fractures, including orthopedic fractures, and 27 (27.55%) patients had chest injuries. Conclusion: Falling from trees is a seasonal phenomenon. In addition to being a major cause of morbidity and mortality, it can impair the quality of life by causing disabilities as well as other damage. Occupational safety experts, public health experts, and clinicians and surgeons should work together to find a solution.
