A Comparative Factor Analysis and New Magnetic Resonance Imaging Scoring System for Differentiating Pyogenic Versus Tuberculous Spondylodiscitis.

Objective: This study aimed to compare and analyze differences in clinical and magnetic resonance imaging (MRI) findings between tuberculous spondylodiscitis (TbS) and pyogenic spondylodiscitis (PyS), and to develop and validate a simplified multiparameter MRIbased scoring system for differentiating TbS from PyS.

Methods: We compared predisposing factors in 190 patients: 123 with TbS and 67 with PyS, confirmed by laboratory tests, culture, or pathology. Data encompassing patient demographics, clinical characteristics, laboratory results, and MRI findings were collected between 2015 and 2020.

Factors Affecting Neurological Deficits in Thoracic Tuberculous Spondylodiscitis.

Background: Thoracic spinal tuberculosis (TB) causes destruction of the spine and compression of the adjacent spinal cord. This study aimed to identify the risk factors for neurological deterioration in patients with thoracic spinal TB to guide decision-making regarding immediate surgery before the onset of weakness.

Methods: Demographic, clinical, laboratory, and radiologic (x-ray and magnetic resonance imaging) data of 115 patients with active thoracic spinal TB were retrospectively analyzed.

IgG4-Related Spinal Hypertrophic Pachymeningitis With Neurological Deficit: A Report of 2 Cases.

Case: Immunoglobulin G4 (IgG4)-related spinal hypertrophic pachymeningitis (IgG4-RHP) is a rare disease characterized by diffuse inflammatory fibrosis of the spinal dura mater that can cause myelopathy and neurological deficits. Here, we report 2 cases in which both patients presented with myelopathy and paraplegia. They underwent decompressive laminectomy, and the diagnoses were confirmed through histopathologic examination.

Incidence and Associated Factors for Kyphosis Progression in Short-Segment Fixation Thoracolumbar Spine Fractures.

Background: The thoracolumbar spine is the most frequently affected portion of the spine during fractures. In surgical management, short-segment fixation is the treatment of choice because of preserved spine motion and fewer complications. However, this technique causes concerns of kyphosis progression compared with long-segment fixation.

Risk factors for polyetheretherketone cage subsidence following minimally invasive transforaminal lumbar interbody fusion.

Background: Interbody cage subsidence is a postoperative complication leading to poor outcomes after minimally invasive transforaminal lumbar interbody fusion (MIS-TLIF). This study aimed to identify risk factors of cage subsidence in lumbar spinal diseases after MIS-TLIF using polyetheretherketone (PEEK) cage.

Methods: In this retrospective cohort study, plain radiographs and three-dimensional computed tomography (3D-CT) performed 12 months after MIS-TLIF were evaluated, and the risk of cage subsidence was calculated with odds ratio (OR), confidence interval (CI), and logistic regression analysis.

Curved versus straight-cut hinges for open-door laminoplasty: A finite element and biomechanical study.

In this study, the stabilities of the hinge sides of plate-augmented open-door laminoplasties based on cutting in a curved or straight line were compared using a finite element (FE) model and an experimental assessment. Using FE models generated from CT scans of a human subject, straight and curved techniques for cutting the hinge side were evaluated. Compressive forces were applied to both simulated models, and the stress distributions on the respective hinge sites were evaluated by comparing the maximum von Mises stresses.

Indirect Decompression Effect to Central Canal and Ligamentum Flavum After Extreme Lateral Lumbar Interbody Fusion and Oblique Lumbar Interbody Fusion.

Study Design: A retrospective study (level of evidence: level 4).

Objective: To evaluate the radiographic outcomes after extreme lateral lumbar interbody fusion (XLIF) and oblique lateral lumbar interbody fusion (OLIF) procedures especially the effect of indirect decompression to the ligamentum flavum and to evaluate the effect of facet degeneration to the radiographic outcomes of these procedures.

Summary Of Background Data: Indirect decompression via lateral lumbar interbody fusion provides spinal canal area expansion.

A Randomized Controlled Trial of Topical Application of Tranexamic Acid in Patients with Thoracolumbar Spine Trauma Undergoing Long-Segment Instrumented Posterior Spinal Fusion.

Study Design: Prospective, randomized controlled trial.

Purpose: To evaluate the effect of topically applied tranexamic acid (TXA) on postoperative blood loss of neurologically intact patients with thoracolumbar spine trauma.

Overview Of Literature: Few articles exist regarding the use of topical TXA for postoperative bleeding and blood transfusion in spinal surgery.
