Objective: To radiographically assess the influence of thoracic hemivertebra on kyphosis and neurologic status in 45 dogs.
Study Design: Case series.
Animals: French Bulldogs without neurologic signs (n = 41) and 4 dogs with compressive spinal cord disease associated with hemivertebra.
Methods: Thoracic spinal radiographs were divided into 3 groups: 1 = dogs with no hemivertebra, 2 = dogs with hemivertebra but no associated neurologic signs, and 3 = dogs with hemivertebra associated with clinical signs. Vertebral canal height, vertebral column angle, and the step between 2 adjacent vertebrae were measured in each group.
Results: Vertebral canal height was not significantly different in the 3 groups; however, mean vertebral column angle was significantly (P < .001) different between groups 1 (178°) and 2 (169°), and group 3 (133°). Median cranial step was significantly different between groups (P < .001): 0 mm (group 1), 0.3 mm (group 2), 3 mm (group 3).
Conclusions: Vertebral canal height does not differ between normal dogs and dogs with thoracic hemivertebra. There is an important association between neurologic signs and kyphosis and subluxation.
Clinical Relevance: Vertebral realignment without vertebral canal opening could lead to spinal cord decompression in dogs affected by thoracic hemivertebra.

A preliminary clinical study related to vestibular migraine and cognitive dysfunction.
Front Hum Neurosci

The First Affiliated Hospital of Harbin Medical University, Harbin, Heilongjiang, China.
Background And Purpose: Vestibular migraine (VM) is a common clinical disorder with a genetic predisposition characterized by recurrent episodes of dizziness/vertigo. Patients often complain of the presence of cognitive dysfunction manifestations such as memory loss, which causes great distress in daily life. In this study, we will explore the characteristics and possible risk factors of VM-related cognitive dysfunction by observing the cognitive function and vestibular function status of VM patients, laying the foundation for further exploration of the mechanisms of VM-related cognitive dysfunction.

Computed tomography (CT) is widely used for the diagnosis and surgical treatment of spinal pathologies, particularly for pedicle screw placement. However, CT's limitations, notably radiation exposure, necessitate the development of alternative imaging techniques. Synthetic CT (sCT), which generates CT-like images from existing magnetic resonance imaging (MRI) scans, offers a promising alternative to reduce radiation exposure.

Department of Radiology, Advantage Imaging and Research Institute, Chennai, India.
Study Design: Matched case-control study.
Purpose: To evaluate the midterm outcomes of unilateral pedicle screw fixation (UPSF) versus bilateral pedicle screw fixation (BPSF) in transforaminal lumbar interbody fusion (TLIF) procedure, ascertain efficacy of UPSF in adequately decompressing contralateral foramen+spinal canal and reducing rate of adjacent segment degeneration (ASD) at 4-8-year follow-up (FU).
Overview Of Literature: Previous meta-analyses found no significant differences between UPSF and BPSF regarding fusion rates, clinical and radiological outcomes; however, few studies have reported higher rates of cage migration/subsidence and pseudoarthrosis in the UPSF.
Current trends in intraoperative neurophysiological monitoring among Asia-Pacific countries: an Asia-Pacific Spine Society survey.

Orthopaedic Surgery Department, Faculty of Medicine, University of Malaya, Kuala Lumpur, Malaysia.
Study Design: A prospective web-based survey.
Purpose: Although intraoperative neurophysiological monitoring (IONM) is critical in spine surgery, its usage is largely based on the surgeon's discretion, and studies on its usage trends in Asia-Pacific countries are lacking. This study aimed to examine current trends in IONM usage in Asia-Pacific countries.
Unilateral biportal endoscopic decompression combined with percutaneous pedicle screw fixation offers new treatment option for thoracolumbar burst fractures with secondary spinal stenosis.

Department of Orthopaedics, The Fourth Affiliated Hospital of Zhejiang University School of Medicine, Yiwu, China.
The purpose of this study was to present the surgical technique of Unilateral Biportal Endoscopic (UBE) decompression combined with percutaneous pedicle screws for the treatment of thoracolumbar burst fractures with secondary spinal stenosis. Thoracolumbar burst fracture is a common traumatic disease in spinal surgery. In the Arbeitsgemeinschaft für Osteosynthesefragen (AO) classification of thoracolumbar fractures, Type A fractures have the highest incidence, accounting for about 70%, with A1 and A3 types being the most common.
