In normal, physiological circumstances there is ample room in the spinal canal to accommodate the spinal cord. Our study aimed to identify the degree of compromise of the spinal canal which could be anticipated in various atlantoaxial pathological states. We examined paired atlas and axis vertebrae using high-definition radiography and simultaneous photography in both normal and simulated patho...

Stenosis of spinal canal becomes important only when it resul...

INTRODUCTION The aim of this paper is to present a noninvasive method for quantifying the spinal canal hydrodynamic compliance from Magnetic Resonance Imaging (MRI) measurements of volumetric cerebrospinal fluid (CSF) flow. The spinal canal compartment contributes to the overall compliance of the craniospinal system. Thus it plays an important role in regulating craniospinal hydrodynamics and i...

Causality between spinal cord compression and polyneuropathy is difficult to define, especially under the circumstances that polyneuropathy can have many causes. Seven patients with spinal cord compression and electrophysiological signs of polyneuropathy were treated surgically on decompression of their spinal canal stenosis in the time from April 2010 to January 2013. Median follow up time was...

PURPOSE All structures of the spine, including the spinal canal, change continuously with age. The purpose of this study was to determine how the spinal canal of the lumbar spine changes with age. The L4/5 is the most common site of spinal stenosis and has the largest flexion-extension motion, whereas the T5/6 has the least motion. Therefore, we measured the spinal canal diameter and vertebral ...

Introduction: Low backache is a common condition to occur in the middle age. It is mainly caused by the degeneration of the intervertebral disc which forms the main support to the vertebral column. Lumbar spinal canal stenosis results in the compression of spinal cord and nerves at the level of lumbar vertebra. Aim: The purpose of this study is to measure the spinal canal dimensions and correla...

Direct measurements were made on 2,166 lumbar vertebrae of 433 adult negro and caucasoid skeletons. On statistical analysis, forty-five vertebrae in twenty-seven skeletons were found to be stenotic, the mid-sagittal diameter being the significantly reduced dimension. Whereas spinal stenosis syndromes are rare in South African negroes, the lumbar canal is marginally narrower in the negro. There ...

Vertebroplasty, a surgical procedure developed by Galibert and Deramond in 1987, involves the injection of bone cement into a collapsed vertebral body. The main indications of vertebroplasty have been extended to painful osteoporotic compression fractures, vertebral myelomas, and metastases and so on. Several previous studies have evaluated the radiological changes in vertebral body height, kyp...

Internal fixation of traumatic spinal injuries has been associated with spinal canal stenosis, spinal cord compression, and nerve root impingement. We present a case of spinal cord/cauda equina compression due to migration of intact, anchored thoracolumbar Luque rods into the spinal canal through a laminectomy defect, leading to neurologic complications 10 years after the original operation.

The centerline of the spinal canal holds interesting information which can be used for tasks such as segmenting the spinal canal or to track the progression of spinal deformities. We propose a method that extracts the centerline of the canal by a shortest path search in 4D, whereby dimensions correspond to 3D canal location and canal width. Our method requires only minimal user interaction in t...
