    Classification of Osteophytes Occurring in the Lumbar Intervertebral Foramen
    (Mdpi, 2024) Tacyildiz, Abdullah Emre; Inceoglu, Feyza
    Background: 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.

    Microendoscopic Discectomy for Lumbar Disc Herniations: A Series of 389 Cases
    (Galenos Publ House, 2023) Bozyigit, Bulent; Abbasoglu, Bilal; Unluer, Caner; Ulku, Goktug; Tacyildiz, Abdullah Emre; Kertmen, Huseyin Hayri
    Objective: Lumbar disc herniation is one of the discogenic causes of lower back pain. Patients with severe nerve root compression or progressive neurologic deficit who do not respond to conventional treatments require surgical intervention. These surgical treatments include minimally invasive and traditional methods. In this study, we have presented the clinical data of patients who underwent microendoscopic discectomy (MED)-a minimally invasive method.Methods: The surgical and clinical data of 389 adult patients who were operated through MED by a single surgeon between 2017 and 2022 were retrospectively evaluated. Parameters such as per-oppostop visual analog scale (VAS), follow-up time, duration of hospitalization, and amount of intraoperative blood loss were examined.Results: Of the 389 patients included in our study, 169 were female and 220 were male, and their mean age was 42.78 years. L4-L5 (n=205, 51.6%), L5-S1 (n=185, 46.8%), L3-L4 (n=4, 1%), and L2-L3 (n=2, 0%) were the most frequently operated levels, showing a sequentially decreasing frequency. Bilateral surgery was performed in two patients. Recurrence was observed in 11 patients (2.8%). Cerebrospinal fluid was detected in 2 (0.5%) patients. The mean pre-and post-op VAS scores were calculated as 7.45 and 1.14, with a significant difference of p<0.001. The mean blood loss during surgery was calculated as 9.6 +/- 5.8 mL, and the postoperative hospital stay was 17.2 +/- 8.5 hours.Conclusion: MED was comparable to conventional methods in terms of symptom relief, recurrence rate, recovery time after surgery, and intraoperative blood loss.

    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, Melih
    Introduction 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.
