Retrospective Assessment of Early Changes in the Sacroiliac Joint After Posterior Lumbar Fusion Surgery via Magnetic Resonance Imaging and Computed Tomography.

Objectives: The need for lumbar-lumbosacral fusion surgery has increased in the recent decade. Although this type of surgical approach has been reported to provide better improvement in low back pain compared with conventional conservative treatments, the ratio of failure varies between 5% and 30% in different studies.

Methods: This retrospective study was conducted through screening patient files between January 2013 and January 2016.

Comparison of the Rigid Rod System with Modular Plate with the Finite Element Analysis in Short-Segment Posterior Stabilization in the Lower Lumbar Region.

Aim: Many studies are available in the literature on posterior spinal instrumentation, though the use of a rod and a plate is still controversial in the literature. In this study, a finite element analysis of the strength and superiority of modular rigid plate and rod systems, which are used in the lower lumbar region, in comparison with each other was used.

Material And Methods: A Ti6Al4V (Grade 5) titanium biocompatible alloy anterior plate was used for the lumbar spine fixation device, and a finite element analysis was conducted on the human lumbar spine model.

Retrospective Comparison of Radiological and Clinical Outcomes of PLIF and TLIF Techniques in Patients Who Underwent Lumbar Spinal Posterior Stabilization.

Degenerative disc disease and spinal stenosis lead to various symptoms. Degeneration of facet joints is added to this degenerative process with aging.Seventy-four patients who were admitted to the Spinal Column Outpatient Clinic of the Neurosurgery Department with a diagnosis of degenerative narrow spinal canal and lumbar spondylolisthesis between 2011 and 2013 and who underwent surgery were included in the study.

Sacrum fractures are rare pathologies seen after spinal traumas. The incidence of a sacral fracture after trauma is 0.6% in childhood.

Thoracolumbar burst fractures requiring instrumented fusion: Should reducted bone fragments be removed? A retrospective study.

Background: Thoracolumbar burst fractures are common clinical entity encountered in neurosurgical practice, accounting for 10-20% of all spinal fractures. Clinical picture could be devastating due to severe neurological deficits which lead the patients dependent both socially and emotionally.

Materials And Methods: This study compared two groups of patients who were operated because of thoracolumbar burst fracture secondary to spinal trauma in terms of neurologic deficits, degree of improvement, and radiologic measurements at one-year follow-up.

A Tethered Cord with Hemivertebra: A Case Report and Review of Literature.

Spinal dysraphisms are defined as open and closed dysraphisms. A hemivertebra is a congenital condition seen in 61% of patients with congenital anomalies. The first report of the excision of a hemivertebra was by Royle in 1928.

Retrospective, Demographic, and Clinical Investigation of the Causes of Postoperative Infection in Patients With Lumbar Spinal Stenosis Who Underwent Posterior Stabilization.

Owing to the increasing population of elderly patients, a large number of patients with degenerative spondylosis are currently being surgically treated. Although basic measures for decreasing postoperative surgical infections (PSIs) are considered, it still remains among the leading causes of morbidity and mortality. The aim of this retrospective analysis is to present possible causes leading to PSI in patients who underwent surgery for lumbar degenerative spondylosis and highlight how it can be avoided to decrease morbidity and mortality.

Comparison of Wiltse and classical methods in surgery of lumbar spinal stenosis and spondylolisthesis.

Aim: Minimally invasive approaches to posterior lumbar surgery are available today that can enhance patient comfort by greatly reducing tissue damage and offer better clinical results. However, such methods have not yet gained widespread popularity despite their significant advantages. This study compares the Wiltse method and the classical method of lumbar surgery based a cohort, clinical study of 57 patients.

Intraoperative antepulsion of a posterior lumbar interbody fusion cage: three case reports.

Spinal fusion surgery techniques develop together with technologic advancements. New complications are seen as the result of new techniques and these may be very severe due to spinal cord and vascular structures in the lumbar region. The posterior lumbar interbody fusion cage (PLIFC) was shown to enhance spinal fusion and to prevent pseudoarthrosis due to its basic dynamic characteristics.

Extraosseous, epidural cavernous hemangioma with back pain.

Background: Cavernous malformations are characterized by enlarged vascular structures located in benign neural tissues within the cerebellum and spinal cord of the central nervous system. Cavernous hemangiomas (CHs) account for 5% to 12% of all spinal vascular malformations.

Case Report: We removed a hemorrhagic thoracic mass in a 40-year-old male patient who presented with progressive neurological deficits.

Isolated Transverse Clivus Fracture without Neurodeficit: Case Report and Review of Literature.

Background: Clivus is a bony surface in the posterior cranial fossa, serving as the support of the brainstem and thus neighboring important structures because of its location. Skull base fractures that cannot be shown by conventional radiography can be clearly imaged by high-resolution bone window computed tomography.

Case Report: A 44 years-old male referred to the emergency department because of a traffic accident in the car.

Thoracic extraosseous epidural cavernous hemangioma.

Cavernous hemangiomas were first reported in 1929 by Globus and Doshay, and are defined as benign vascular structures developed between the neural tissues occurring in the central nervous system, consisting of a dilated vascular bed. Cavernous hemangiomas comprise nearly 5-12% of all spinal vascular malformations; however, existence in the epidural space without bone involvement is rare. Only 4% of all cavernous hemangiomas (0.

Intraorbital Encephalocele Presenting with Exophthalmos and Orbital Dystopia : CT and MRI Findings.

A 15-year-old female patient with progressive pulsatile exophthalmos caused by intraorbital encephalocele was evaluated with computed tomography (CT) and magnetic resonance imaging (MRI) in our clinic. She had no history of trauma or reconstructive surgery. When she was a little girl, she had undergone surgery for congenital glaucoma on the right eye.

Combined therapy for distant metastasis of sacral chordoma.

Chordomas are known as rare primary malign tumours that have formed from primitive notochord remains. Sacral chordomas grow slowly but locally and aggressively. Chordomas are locally invasive and have low tendency to metastasis and have a poor prognosis in long-term follow-up.

Primary intraosseous meningioma mimicking osteosarcoma: case report.

With an incidence rate of 15-20%, meningiomas are one of the most common brain tumors among benign intracranial tumors. They are distributed as follows in intracranial localizations: parasagittal and falx (25%), convexity (18%), sphenoid wing (18%), parasellar (12%), posterior fossa (10%), intraventricular (2%), intraorbital (1%), and extracranial (1%). The most common extradural localizations are the paranasal sinuses, nasal cavity, skin, neck, glands, and intraosseous space.

Aneurysmal bone cysts are rare entities which causes expansile and destructive bone lesions characterized by reactive proliferation of connective tissue. They usually grow rapidly with hypervascularity. In clinical practice they can be easily misdiagnosed due to the rare occurance and having no such typical findings as radiologically.
