STUDY DESIGN In vivo biomechanical study using a three-dimensional (3D) musculoskeletal model for elderly individuals with or without pelvic retroversion. PURPOSE To evaluate the effect of pelvic retroversion on the sagittal alignment of the spine, pelvis, and lower limb in elderly females while standing and walking. OVERVIEW OF LITERATURE Patients with hip-spine syndrome have concurrent hi...

BACKGROUND CONTEXT Sagittal standing posture is associated with musculoskeletal symptoms and quality of life. However, the frequency and determinants of suboptimal sagittal alignment outside the clinical context remain to be clarified. PURPOSE To estimate the association of sociodemographic, anthropometric, and behavioral characteristics with sagittal standing posture among adults from the ge...

A relationship between spinal deformity and ambulation is yet to be clarified. We hypothesized that undesirable spino-pelvic alignment affects walking ability. The purpose of present study is to clarify an influence of spinopelvic alignments on walking ability. Consecutive patients who visited our institution between October 2011 to September 2012 were retrospectively surveyed. The cases of neu...

This article is a comparative study. The aim of the study is to investigate the difference of sagittal alignment of the pelvis and spine between patients with thoracolumbar kyphosis secondary to ankylosing spondylitis (AS) and thoracolumbar fracture, and to evaluate the role of sacropelvic component in AS patients' adaption to the changes in sagittal alignment. Advanced stages of AS are often a...
