A cadaver's vertebral column, a phantom, and a volunteer were imaged on a 1.5-T MR scanner to study the thin, uniform, dark, transverse lines that characterize some intervertebral disks. An artifactual dark line appears when the field of view (FOV) and matrix steps (n) are chosen so that d = FOV/n, where d equals the intervertebral disk height, or spacing between phantom vertebrae. The artifact...

Acute spinal cord injuries commonly seen in veterinary patients include vascular, compressive, and concussive injuries. Vascular lesions, or infracts, are usually caused by fibrocartilagenous emboli. Concussive and compressive injuries have a variety of pathologies, including intervertebral disk disease, fractures, and luxations (dislocations) of the vertebral column. Although considerable cont...

In the setting of spinal trauma, the bone, ligaments, spinal cord, and vascular structures may be injured. Anatomically, the vertebral bony spine can be divided into structural columns. The cervical spine is traditionally divided into two columns— anterior and posterior. The anterior column consists of the load-bearing vertebral bodies, intervertebral disks, anterior longitudinal ligament, and ...

seven caspian miniature horses, aged above two years, were used for this study. the skeleton of these horses were cleaned and prepared using appropriate techniques. the vertebral column was studied and photographed. the vertebral column in one of these horses showed variations in thoracic, lumbar and sacral region. the vertebral formola was c7, t19,l5,s6 and a pair of 19th rib was fused with th...

  Abstract   Malacoplakia is a rare chronic inflammatory disease associated with infection and immunosuppression, and very few occurrences have been reported in the bone. The authors describe the case of a 22-year-old woman with paraplegia and urinary and fecal incontinence whose thoracic spine Magnetic Resonance Imaging suggested a tumoral or extensive inflammatory process in the body of the 8...

A sandwich vertebra is formed after multiple osteoporotic vertebral fractures treated by percutaneous vertebroplasty, which has a risk of developing new fractures. The purpose of our study was to (i) investigate the occurrence of new fractures in sandwich vertebra after cement augmentation procedures and to (ii) evaluate the clinical outcomes after prophylactic vertebral reinforcement applied w...

OBJECTIVE To analyze the clinical results of a partial vertebrectomy with titanium mesh implantation and pedicle screw fixation using a posterior approach to reconstruct the spine in the treatment of thoracolumbar burst fractures. METHOD From January 2006 to August 2008, 20 patients with severe thoracolumbar fractures were treated.For vertebral bodies associated with one injured intervertebra...

OBJECTIVE To characterize and compare the MRI morphological features of the cervical vertebral column of Great Danes with and without clinical signs of cervical spondylomyelopathy (CSM). DESIGN Prospective cohort study. ANIMALS 30 Great Danes (15 clinically normal and 15 CSM-affected). PROCEDURES All dogs underwent MRI of the cervical vertebral column (C2-3 through T1-2). Features evaluat...

Introduction: Vertebral arteries arise from the root of the neck as the first branches from the superior-posterior aspect of the subclavian arteries. They ascend the neck to enter the cranial cavity and supply blood to the brain. Methods: A total of 20 cadavers (in 10 years) were dissected for the study of variations in the origin of the vertebral artery. This study was conducte...
