Various actions on the lumbar spine have been attributed to quadratus lumborum, but they have not been substantiated by quantitative data. The present study was undertaken to determine the magnitude of forces and moments that quadratus lumborum could exert on the lumbar spine. The fascicular anatomy of quadratus lumborum was studied in six embalmed cadavers. For each fascicle, the sites of atta...

BACKGROUND AND PURPOSE The method of treating an HIVD in the lumbar spine may depend on the integrity of the PLL. The purpose of this study was to analyze and compare the MR imaging findings of extraligamentous and subligamentous HIVDs in the lumbar spine. MATERIAL AND METHODS One hundred seventeen patients (M/F = 71:46; mean age, 47 years; age range, 15-79 years) underwent lumbar spine MR im...

Background. The aim of our study was to assess the course and outcome in scoliosis without spondylodesis in the lumbar spine after surgical correction performed in the thoracic segment with the C-D method in patients with King's type II scoliosis (Lenke's IB, IC). Material and methods. 42 patients with idiopathic scoliosis were operated in the thoracic spine. The Cobb's angle averaged 635 +/- 9...

OBJECTIVE Osteoarthritis (OA) and osteoporosis are often considered to lie at opposite ends of a spectrum of bone phenotypes. Lumbar degenerative disc disease (LDD) may be associated with low back pain (LBP) and is similar in many ways to OA. LDD is reported in small studies to be associated with increased spine bone mineral density (BMD). The present work aimed to confirm this association in a...

OBJECTIVES We aimed to investigate the association of serum uric acid (UA) levels with bone mineral density (BMD) at all skeletal sites in healthy Chinese males >50 years of age. METHODS A cross-sectional study of 385 Chinese males >50 years of age who underwent health checkup in Huadong Hospital Affiliated to Fudan University in Shanghai, China, was conducted. Clinical and bone characteristi...

STUDY DESIGN Case control study. PURPOSE To examine the effect of spino-pelvic sagittal parameters and back muscles on osteoporotic vertebral fracture. OVERVIEW OF LITERATURE Low bone mass is not the only important component of the risk on osteoporotic vertebral fracture; many other risk factors also contribute to skeletal fragility. METHODS Seventy-two patients who had a lateral radiogra...

Background. Band exercise can also reduce back pain by reducing unnecessary movement of the thoracic and cervical vertebrae adjacent to the lumbar spine. Looking at previous studies, activation of the deep lumbar muscles of the lumbar spine and restoration of mobility of the adjacent skeleton have a positive effect on pain relief. Objectives. This study was to investigate the effects of self-f...

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...
