Öğe Abdominal vascular injury during lumbar disc surgery: report of three cases(TURKISH ASSOC TRAUMA EMERGENCY SURGERY, 2007) Torun, Fuat; Tuna, Hakan; Deda, HalukAnterior longitudinal ligament perforation and abdominal vascular injury is one of the most critical complications that may develop during lumbar disc surgery. The vascular injury-related symptoms that warns the surgeon may be late to appear; they usually turn out to be mortal. The hypotension during the operation, tachycardia and pulsatile unstoppable hemorrhage observed in the disc space are the major findings. Urgent detection of this complication and the repair of the vascular injury prevent the case from turning out to be fatal. In the present study, three patients who underwent surgical treatment of abdominal vascular injuries that had developed during lumbar disc surgery, were presented.Öğe Akademik bir örgütte iletişim doyumunun örgütsel özdeşleşmeye etkisi(Selçuk Üniversitesi İletişim Fakültesi, 2017) Derin, Neslihan; Tuna, HakanÇalışma hayatında da olumlu ve sağlıklı ilişkilerin varlığı, bireylerin mesleklerine ve örgütlerine olan bakış açılarını pozitif kılacaktır. Çalışanların organizasyon içindeki ilişkilerden ve bilgi akışından elde ettiği tatmini yansıtan iletişim doyumunu değerlendirmek, örgütsel iletişimin etkililiğinin belirlenmesinde önemli bir faktördür. Etkili örgütsel iletişim ile üyenin örgütle özdeşleşmesi yani “bireylerin kendilerini kurumlarının bir unsuru olarak tanımlamaları” güçlendirilebilinir. Akademik örgütler, insan ilişkilerinin yüksek olduğu ve eğitim düzeyleri yüksek olan insanların çalıştığı yerlerdir. Bu tür örgütlerde her türlü beklenti yüksek olabileceği gibi iletişime dönük beklenti de yüksek olacaktır. Bu çalışmanın amacı, bir akademik örgüt olarak İnönü Üniversitesi’ndeki öğretim elemanlarının iletişim doyum ve örgütsel özdeşleşme düzeylerini tespit etmek iletişim doyumunun örgütsel özdeşleşmenin bir belirleyicisi olduğunu ortaya koyabilmektir. Yapılan araştırmayla, öğretim elemanlarının genel iletişim doyum ortalamalarının orta düzeyde olduğu, örgütsel özdeşleşme düzeylerinin ortanın üstünde olduğu, iletişim doyumunun örgütsel özdeşleşme üzerinde anlamlı belirleyici bir etkiye sahip olduğu sonucuna ulaşılmıştır.Öğe Bilateral Traumatic Neuroma of the Anterior Cervical Nerve Root(2005) Torun, Fuat; Tuna, Hakan; Kahiloğulları, Gökmen; Bağdatoğlu, Celal; Çağlar, ŞükrüObjectives. A rare case of anterior cervical second root traumatic neuroma with no history of trauma is reported, and possible etiology is discussed. Summary of Background Data. Traumatic neuroma is the reactive, nonneoplastic proliferation in the injured nerve. Several atypical locations of traumatic neuroma have been reported. To date, only 4 cervical traumatic neuroma cases with no history of trauma have been reported, and, to our knowledge, there is no case of bilateral cervical traumatic neuroma published in the literature. Methods. A patient with a history of neck and left upper extremity pain, who had hypoesthesia in left C2 dermatome on neurologic examination is presented. A left C2–C3 hemilaminectomy and tumor extirpation were performed. Results. A histopathologic study revealed features of a typical traumatic neuroma. The patient had no deficits on her postoperative neurologic examination, and her neck and left arm pain improved. The unusual location of this lesion and possible etiology of such a traumatic neuroma are discussed. Conclusions. A rare case of anterior bilateral cervical second root traumatic neuroma with no history of trauma is reported. An unnoticed history of trauma may play an etiologic role in the development of these lesions.Öğe The lumbar roots and pedicles: a morphometric analysis and anatomical features(ELSEVIER SCI LTD, 2008) Torun, Fuat; Tuna, Hakan; Buyukmumcu, Mustafa; Caglar, Sukru; Baysefer, AlperThe objective of this study was to conduct a morphometric analysis of the lumbar nerve roots and surrounding structures. In this investigation, the lumbar roots were studied in 14 cadavers (70 lumbar vertebrae). Lumbar pedicle heights and widths were measured at every level of the lumbar vertebrae. The largest mean root diameter was 5.6 mm (L5 root) and the smallest 3.5 mm (L1 root). With regard to the root-dura exit angle, the widest was measured at L1 as 26.2 +/- 1.6 degrees and the narrowest at L5 as 16.3 +/- 2.4 degrees. The widest lumbar pedicle was measured at L5 as 17.1 +/- 4.2 mm and the narrowest at L1 as 8.4 +/- 1.8 mm. The longest lumbar pedicle was measured at L2 as 15.3 +/- 2.2 mm and the shortest at L4 as 13.8 +/- 2.3 mm. Quantitative measurements of lumbar root diameters, their exit angles from the dura, and lumbar pedicle heights and widths in anatomical dissection models may help us to gain a deeper understanding of the pathologies of this region and positively influence the success of surgical interventions.

Methods: Using the recent breakthroughs in microscopic anatomic dissections, the roots and vertebral foramina of the lumbar region were examined in 15 cadavers. Morphometric analysis of the roots and vertebral foramina of 80 lumbar vertebral objects was conducted. Results: The transverse and sagittal diameters of the lumbar intervertebral foramina were measured at each vertebral level. The median diameter of the lumbar neural foramina was 8.8 +/- 1.7 mm for the transverse and 19.4 +/- 2.7 mm for the sagittal planes. The widest median diameter of roots was 3.9 mm in the L4 root, and the narrowest was 3.3 mm in the L1 root. Conclusion: Quantitative measurements of the diameters of the neural foramina and roots of the lumbar region in anatomic dissection models may provide a deeper understanding about the pathologies of this region and influence the success of surgical interventions.
