Two phantoms were constructed and imaged for the purpose of reproducing and understanding the relatively increased signal intensity of intervertebral disks on T1-weighted MR images in three patients with diffuse vertebral metastases. The first phantom simulated a normal spine and showed that the disks and vertebral bodies were of similar intensity. The second phantom simulated an abnormal spine...

Klippel-Feil syndrome is a condition characterized by fusion of the spine owing to failure normal segmentation cervical structures. In this case report, we aimed describe rare syndrome, show findings using imaging techniques, and demonstrate its clinical importance. A 41-year-old female patient presented our faculty hospital with neck pain. Using magnetic resonance imaging, observed decreased a...

Right: lateral view oflumbar spine showing narrowing ofdisc spaces ofT12 andL I and kyphos between L2 and L4, pseudo-Schmorl's nodes at upper and lower surfaces of T12, and bridging anterio-lateral osteophytes between L2 and L4. Only vestiges ofposte...

Percutaneous vertebroplasty (PVP) is a procedure in which bone cement is injected into vertebrae under fluoroscopic guidance. It was reported to be effective and safe for the treatment of back pain due to compression fractures of the spine [1,2]. As PVP has been successfully used to treat compression fractures of the spine in patients with malignant and non-malignant hematologic diseases, we th...

Assessment of the cervical spine using x-ray radiography is an important task when providing emergency room care to trauma patients. In clinical practice, a physician will inspect the alignment of the cervical spine vertebrae by mentally tracing three alignment curves along the anterior and posterior sides of the cervical vertebral bodies, as well as one along the spinolaminar junction. In this...

In this paper we propose a simple model for the coupling behavior of the human spine that is capable of exhibiting anatomically correct motions of the vertebrae in virtual mannequins. Such a model transparently integrates in our inverse kinematics framework as it couples standard swing and revolute joint models. The adjustment of the joints due to the coupling is made with several simple (in)eq...

Posterior spinal instrumentation and fusion techniques are used over decades to correct spinal deformities higher than 40 degrees in scoliotic subjects [1]. Although these methods are successfully decreased the spinal curvature in scoliosis, the biomechanical loading of the distal unfused vertebrae is not well studied after operation. Among unfused vertebrae sacrum, the connective vertebra betw...

The yellow ligament, or Ligamentum flavum, is the ligament that connects lamina arches of two adjacent vertebrae in spine [1,2]. This and has elasticity [3,4]. flavum ossification an uncommon cause pressure on cervical cord [3] [5-7]. commonly occurs thoracic which can myelopathic symptoms patient [8,9]. main this problem unknown, but it when soft tissue calcified causes narrowing spinal canal ...

[Purpose] To investigate whether thoracic spine mobilization added to stabilization exercises increases the muscular strength and range of motion of the thoracic vertebrae of chronic low-back pain patients. [Subjects] This study enrolled 20 patients with chronic low back pain, who were divided into two groups. Ten subjects were randomly selected for the stabilization exercise group and the rema...

Patients with diffuse idiopathic skeletal hyperostosis (DISH) develop fractures of the vertebral bodies, even in minor trauma, because loss flexibility, which causes difficulties fusing vertebrae; therefore, diagnosis spine injuries may be delayed. We used three-dimensional finite element method to add data on ossification healthy model order investigate how stress intervertebral discs changes ...
