OBJECTIVE To investigate the relationship between bone mineral density (BMD) and sagittal spinal balance in the Korean elderly population. METHODS The retrospective study included subjects aged 60 years and above, who had whole-spine lateral radiography and dual-energy X-ray absorptiometry (DEXA) within a year's gap between each other. Sagittal vertical axis (SVA) for evaluation of sagittal s...
In many computer interfaces the underlying structures and contingencies are often hidden from the user's view. Users high in Spatial Visualization Ability (SVA) are able to quickly determine and manage the contingencies of these relationships and are not severely affected by this problem. Low SVA users, however, have difficulty visualizing these contingencies and often get lost. We examined the...
This investigation determined relationships between coronal vertical alignment (CVA) and sagittal vertical alignment (SVA) variables calculated from radiographs and surface markers representing bony landmarks. Biplanar radiographs were taken on 28 subjects (standing) after 2 metallic surface markers were placed on the skin superficial to C7 and S2. The CVA-R and SVA-R were measured on the radio...
OBJECTIVES To establish the normal values of spino-pelvic alignment and to clarify the effect of age-related changes using large, community-based cohorts. METHODS In this study, data from 1461 participants (466 men, 995 women) were analyzed. On lateral standing radiographs, the following parameters were measured: thoracic kyphosis (TK), lumbar lordosis (LL), pelvic tilt (PT), pelvic incidence...
STUDY DESIGN Retrospective case series. OBJECTIVE To investigate which sagittal parameters contribute to a normal sagittal vertical axis (SVA) when there is a pelvic incidence-lumbar lordosis (PI-LL) mismatch >10° following adult spinal deformity (ASD) correction. METHODS We performed a retrospective review of ASD patients with >5 levels fused. Sagittal measurements between cohorts of posto...
Genetic mutations of FUS have been linked to many diseases including Amyotrophic Lateral Sclerosis (ALS) and Frontotemporal Lobar Degeneration. A primate specific and polymorphic retrotransposon of the SINE-VNTR-Alu (SVA) family is present upstream of the FUS gene. Here we have demonstrated that this retrotransposon can act as a classical transcriptional regulatory domain in the context of a re...
What we see is not always what we get. This is the problem when the underlying structure of an interface is hidden from the user's view. Users high in Spatial Visualization Ability (SVA), are quick to learn the contingencies of these relationships and are not hindered by this problem. Low SVA users, however, have difficulty visualizing these contingencies and often get lost. We examined data fo...
INTRODUCTION This study investigated the relationship between the parameters related to the natural head position and cervical segmental angles and alignment of patients with neck pain. MATERIAL AND METHODS The lateral radiographs of the cervical spine were collected from 103 patients and were used to retrospectively analyze the correlation between the natural head position, cervical local sa...
2014–2015 in Brazil, which were associated with idiopathic vesicular disease and neonatal death. Little diagnostic testing is performed on culled animals, which may in part explain the discrepancy between 1% of oral fluids submitted for diagnostic testing being positive for SVA (7), compared with 72% of culled swine swab specimen pools in this study . The sole sample from primary markets that w...
