Hip-spine coordination, known as the lumbopelvic rhythm, can be expressed as the lumbar-hip ratio. The lumbopelvic rhythm and lumbar-hip ratio can be used to assess lower limb function. We clarified the lumbopelvic rhythm and lumbar-hip ratio during trunk extension. We established a novel set of marker positions for three-dimensional motion analysis to assess the lumbar spinal angle. The origin...

Guillain-Barré syndrome (GBS) is a term that is used to describe a group of immune-mediated peripheral neuropathies, with the most common feature being rapid polyradiculoneuropathy. The exact etiology of this syndrome is unknown. In the field of orthopedics, GBS has been reported to occur after total hip arthroplasty, orthopedic trauma, and spine surgery. We report a unique case of GBS after el...

BACKGROUND The purpose of this study was to establish complete normative bone mineral density (BMD) values of Taiwanese men for anteroposterior, lateral spine, and hip. METHODS Five-hundred and 69 healthy men (aged 20 to 88 years) were recruited to establish normal reference data of lumbar spine and hip, measured by a Hologic QDR 2000 bone densitometer. One-way analysis of variance was used t...

PURPOSE The preoperative prevalence of osteoporosis and/or osteopenia and overall bone quality in prospective total knee arthroplasty (TKA) patients may affect the postoperative outcome after prosthetic insertion into the bone. The purpose of this study is to determine the baseline bone mineral density (BMD) and bone turnover in preoperative, female, primary TKA patients. METHODS We prospecti...

OBJECTIVE Hearing impairment has been suggested to increase the risk of falls. However, most previous studies were conducted in an older population without classification of the fracture regions. This study aimed to delineate the risk of each fracture type in all age populations. METHODS The Korean National Health Insurance Service-National Sample Cohort was collected from 2002 to 2013. A tot...

The kinematic relationship between the hip and the axial skeleton is dynamic and can be variable based on individual anatomy. It has been shown [1] that pelvic incidence (sacral slope + pelvic tilt) can be used as a proxy to determine the ability of the pelvis to accommodate changes in sagittal balance. Individuals have varied pelvic incidence and thus may adapt differently degenerative and/or ...

Introduction Spinal kinematics/motion are reported to be altered in adolescents and adults with essential obesity, while no information is available patients Prader-Willi syndrome so far. The aim of this study was examine cross-sectionally the characteristics spinal postures mobility 34 PWS, 35 age- sex-matched 37 normal-weight individuals. Methods posture were assessed using a radiation-free b...

To determine the correlation between the bone mineral density (BMD) and spinal mobility and chest expansion index in patients with ankylosing spondylitis. Eighty patients with confirmed diagnosis of ankylosing spondylitis were included in this study. In all of them physical examination was performed including assessment of spinal mobility and chest expansion index. Bone mineral density of the l...
