Spinal stenosis may rarely involve both cervical and lumbar spines. An alternative surgical strategy used for the treatment of combined cervical and lumbar spinal stenosis is presented. Two cases with symptomatic combined stenosis of the cervical and lumbar spinal canal are described. Simultaneous surgery was performed in both cases. The combined stenosis of the cervical and lumbar spinal canal...

Three cases of postoperative lumbar spinal canal stenosis due to anterior spinal fusion were reported. In these cases stenosis occurred at the adjacent intervertebral disc level of the fused segment a considerable time after anterior spinal fusion performed for spondvlolisthesis. At the stenotic level of the lumbar spinal canal, hypertrophy of the lamina, body spur formation in the articular pr...

Three cases of multiple spinal canal meningiomas are presented, bringing the total number of documented cases in the American literature to nine. While the exact incidence of multiple spinal meningiomas is difficult to determine, their possible occurrence warrants careful myelographic examination of the whole spinal canal, particularly if multiple clinical levels are present. When a complete bl...

BACKGROUND AND PURPOSE Percutaneous vertebroplasty can aggravate spinal canal narrowing, especially in patients with preoperative retropulsion. The purpose of this study was to evaluate changes in spinal canal dimension during percutaneous vertebroplasty for osteoporotic fractures with retropulsion. MATERIALS AND METHODS We reviewed all cases of osteoporotic vertebral fractures treated with v...

Introduction: Stenosis or narrowing of spinal canal is a common cause of cervical pain and a risk factor for development of spondylotic myelopathy.The aim of the present study was to determine the normal values of the cervical spinal canal and spinal cord in antero-posterior dimensions on MRI in Kashmiri adults of Kashmiri ethnicity Materials and Methods: The measurements were made on 100 MRI s...

PURPOSE To assess the correlation between the presence of lamina fractures, narrowing of the spinal canal, and the severity of injury. METHODS Records of 146 men and 44 women aged 13 to 84 (mean, 39) years diagnosed with burst fractures of the thoracolumbar spine were retrospectively reviewed. The laminar fractures and narrowing of the spinal canal were measured using computed tomography. The...

To assess the changes in the curvature of the spinal column in the supine position during pregnancy, we studied seven pregnant (32-37 weeks of pregnancy) and seven non-pregnant women using magnetic resonance imaging. T1-weighted sagittal midline magnetic resonance images of the spinal column were obtained with subjects in the supine position with left tilt. There was no significant difference i...

PURPOSE To document the occurrence of isolated dorsal subluxation of posterior elements in cases of lumbar spondylolysis without spondylolisthesis both quantitatively (using spinal canal measurements) and qualitatively (by visual inspection) on sagittal MR images. METHODS Retrospective analysis identified 63 patients with lumbar spondylolysis (confirmed by CT or conventional radiography) who ...

The aim of this study was to measure changes in the cross-sectional area of the spinal canal and the area of the intervertebral foramen for each pedicle segment before and after the pedicle extension using computer-simulated transpedicular osteotomy to provide a theoretical basis for clinical decompression in the lumbar spinal canal. Using spiral CT scanning of the original lumbar spine, a fini...
