STUDY DESIGN A morphometric analysis, using magnetic resonance imaging (MRI) studies of the lumbar spine. OBJECTIVE To identify the anatomic position of the ventral root and the retroperitoneal vessels in relation to the vertebral body in normally aligned and deformed spines. SUMMARY OF BACKGROUND DATA The lateral approach to the lumbar spine is a relatively new method for performing interb...

RATIONALE Fixed thoracolumbar kyphosis with spinal stenosis in adult patients with achondroplasia presents a challenging issue. We describe the first case in which spondylectomy and minimally invasive lateral access interbody arthrodesis were used for the treatment of fixed severe thoracolumbar kyphosis and lumbar spinal canal stenosis in an adult with achondroplasia. PATIENT CONCERNS A 61-ye...

Introduction: Lumbar spinal stenosis is a frequent cause of low back pain. Decreased lumbar canal parameters are major risk factors for stenosis. This study was done to assess anteroposterior diameter, interpedicular distance and cross-sectional area the on CT scan.
 Methods: It descriptive conducted at Nepal Medical College Teaching Hospital. Anteroposterior were measured.
 Results: ...

Longer spinal fusions have been shown to result in improved deformity correction; however, loss of normal flexibility in the fusion area should not be ignored. Current consensus was to achieve a shorter fusion in primary surgery, with the goal of preserving as much of the distal motion segment as possible. However, the correlation between the length of fusion and functional outcome remains cont...

STUDY DESIGN An anatomic study of facet angle orientation and morphology of the lumbar spine was performed. OBJECTIVE The aim of this study was to determine how age, gender, race, and pelvic incidence (PI) correlate with facet orientation in the lumbar spine. SUMMARY OF BACKGROUND DATA Lumbar facet orientation has important implications in the development of numerous pathologies of the spin...

The segmental organization of the hindlimb locomotor pattern generators and the coordination of rhythmic motor activity were studied in isolated spinal cords of the neonatal rat. All lumbar segments and many thoracic and sacral segments of the cord exhibited an alternating left-right rhythm in the presence of serotonin (5-HT) and N-methyl-D-aspartate (NDMA). Other thoracic segments exhibited a ...

STUDY DESIGN A retrospective radiographic study. PURPOSE To verify the correlation of sagittal and coronal plane changes after selective thoracic fusion in main thoracic (MT) adolescent idiopathic scoliosis (AIS). OVERVIEW OF LITERATURE Sagittal plane deformity is known to be essential in the evolution of scoliosis. METHODS Twenty-eight MT AIS patients treated by anterior selective thorac...

SHIMADA, Y., KASUKAWA, Y., MIYAKOSHI, N., HONGO, M., ANDO, S. and ITOI, E. Chronic Subdural Hematoma Coexisting with Ligamentum Flavum Hematoma in the Lumbar Spine: A Case Report. Tohoku J. Exp. Med., 2006, 210 (1), 83-89 ── We present a case of a chronic spinal subdural hematoma combined with a ligamentum flavum hematoma in the lumbar spine treated surgically. An 83-year-old woman receiving an...

We report the case of a 30-year old patient, with no particular pathological history but with a 6-months history of lower back pain without radiculalgia in the lower limbs. Neurological examination showed lumbar spinal syndrome without neurological deficit. Lumbar spine CT scan on the right (A) and left (B) paramedian sagittal slices showed bilateral three-level L2, L3, L4 spondylolysis associa...

BACKGROUND To investigate the distribution and characteristics of the lumbar intervertebral disc height (IDH) in asymptomatic Asian population and to determine whether the lumbar IDH is related to the lumbar spine sagittal alignment. METHODS A cohort of 169 cases of asymptomatic volunteers was enrolled from January 2014 to July 2016. All participants underwent magnetic resonance imaging of th...
