The mobility of the spine and the change in the angle of the curvatures are directly related to spinal pain and spinal stenosis. The aim of the study was the evaluation of morphology and mobility of the spine in patients who were subjected to decompression and posterior fusion with pedicle screws. The treatment group consisted of 20 patients who underwent posterior fixation of lumbar spine (one...

Background: Scoliosis is a health problem that causes a side-to-side curvature in the spine. The curvature may have an “S” or “C” shape. To evaluate scoliosis, the Cobb angle has been commonly used. However, digital image processing allows the Cobb angle to be obtained easily and quickly, several researchers have determined that Cobb angle contains high variations (errors) in the measurements. ...

The Lie group Sol(p, q) is the semidirect product induced by the action of R on R which is given by (x, y) 7→ (ex, e−qzy), z ∈ R. Viewing Sol(p, q) as a 3-dimensional manifold, it carries a natural Riemannian metric and Laplace-Beltrami operator. We add a linear drift term in the z-variable to the latter, and study the associated Brownian motion with drift. We derive a central limit theorem and...

  Background: Postural structure abnormalities have been highly prevalent among children in primary school children.The present study aimed to assess the relationship between the backpacks weight and method of carrying with postural structure disturbances in primary school children.   Materials and Methods: This cross-sectional study was performed on 472 primary school children in Karaj-Iran. ...

Scoliosis is a three‐dimensional (3D) spinal deformity involving one or more spine curvatures with vertebral rotation. In the past 30 years, Chinese spine surgeons adopted international advanced technology and concepts, took advantage of abundant Chinese patient resources with severe deformity, and developed novel ideas and techniques, which promoted the development of the diagnosis and treatme...

Objectives/Goals Considering the variety of spinal deformity treatments, many patients agree that after surgery their mobility is significantly reduced. The utilization of resorbable materials for anterior spinal fusion systems, patients will experience the success of spinal deformity treatment and retain their prior mobility. If the systems are used on vertebrae with larger anterior width, the...

The objectives were 1) to evaluate the hamstring muscle flexibility in children and adolescents; 2) to examine the relative contribution of the spinal curvatures, pelvic tilt and hamstring flexibility on the sit-and-reach (SR) score; and 3) to determine the validity of the sit-and-reach test through both active and passive hip flexion tests. 118 children and adolescents (aged 7-18 years; 60 mal...
