Lumbar Spine Vertebral Motion Characters in Sagittal and Transverse Planes
ثبت نشده
چکیده
Previous in-vivo studies have mostly used X-ray images to measure the vertebral rotational centers in sagittal plane. Recently, advanced medical image techniques such as CT, MRI and dual plane fluoroscopic have enabled investigation of 3D motions of the vertebral body in space. We have applied the combined dual fluoroscopic imaging system (DFIS) and MR imaging technique to investigate the 6DOF motion of human lumbar spine [2-4]. Combined with 3D vertebral geometry, we investigated motion characters at different portions of the vertebrae and the rotational centers of the vertebrae in the sagittal and transverse planes.

In-vivo motion characteristics of lumbar vertebrae in sagittal and transverse planes.
Lumbar vertebrae are complicated in structure and function. The purpose of this study was to investigate the in-vivo motion characteristics of different portions of the lumbar vertebrae during functional activities. Motion of L2, L3 and L4 was reproduced using a combined dual fluoroscopic and MR imaging technique during flexion-extension and left-right twisting of the trunk. The ranges of motio...
متن کاملHelmet fit and cervical spine motion in collegiate men's lacrosse athletes secured to a spine board.
CONTEXT Proper management of cervical spine injuries in men's lacrosse players depends in part upon the ability of the helmet to immobilize the head. OBJECTIVE To determine if properly and improperly fitted lacrosse helmets provide adequate stabilization of the head in the spine-boarded athlete. DESIGN Crossover study. SETTING Sports medicine research laboratory. PATIENTS OR OTHER PARTI...
متن کاملLumbar Scoliosis Induction in Juvenile Dogs by Three-dimensional Modulation of Spinal Growth Using Nickel-Titanium Coil Springs
BACKGROUND Current treatments for scoliosis have some defects and complications. To study spinal deformities and test novel scoliosis treatments, many animal models of scoliosis have been developed. These models applied a single load to the spine and could not precisely modulate the spinal growth in different dimensions. In this study, we applied posterior tethering in various directions with t...
متن کاملTreatment of 44 Cases With Lumbar Spine Stenosis and Degenerative Instability: Outcomes of Surgical Intervention
Background and Aim: Degenerative lumbar spine disease can lead to lumbar spine instability. The patients can present with Low Back Pain (LBP), radicular pain, and motor and sensory dysfunction. Age >50, female sex and pregnancies are among prevalent risk factors. The degeneration process usually starts from the intervertebral discs progressing to involve facet joints, ligaments, and vertebral b...
متن کاملKinematic analysis of symmetric axial trunk rotation on dominant hip.
Axial rotation of the trunk has been reported as a significant risk of low back dysfunction. However, a lack of biomechanical investigation exists that explains how twisting is accomplished with simultaneous asymmetric handling between the hip joints and lumbar spine. We used a three-dimensional motion analysis to measure movements of the bilateral hips and lumbar spine. Forty-four persons part...
