Disability questionnaires are used for clinical assessment, outcome measurement, and research methodology. Any disability measurement must be adapted culturally for comparability of data, when the patients, who are measured, use different languages. This study aimed to conduct cross-cultural adaptation in translating the original (English) version of the(More)
STUDY DESIGN A prospective study of 12 patients with thoracolumbar spinal fractures was conducted. OBJECTIVE To assess the feasibility of ultrasound examination for posterior ligament complex injury in thoracolumbar spinal fractures. SUMMARY OF BACKGROUND DATA In posterior ligament complex injury of thoracolumbar spine fracture, the reliability of(More)
STUDY DESIGN In vitro experiment using rabbit nucleus pulposus (NP) cells seeded in atelocollagen scaffolds under the stimulation of growth factors. OBJECTIVE To demonstrate the effect of anabolic growth factors in rabbit NP cells cultured in atelocollagen type I and type II. SUMMARY OF BACKGROUND DATA Atelocollagen provides intervertebral disc (IVD)(More)
STUDY DESIGN Retrospective study. OBJECTIVES To investigate the overall surgical outcome of lumbar fusion surgery in patients with Parkinson disease (PD). SUMMARY OF BACK GROUND DATA: Poor bone quality and muscular dysfunction are important clinical manifestations connected with musculoskeletal diseases in PD patients. These secondary changes caused by PD(More)
STUDY DESIGN In vitro experiment using bone morphogenetic protein-2 (BMP-2) and human intervertebral disc (IVD) cells. OBJECTIVES To demonstrate the effect of BMP-2 on mRNAs expression (collagen type I, collagen type II, aggrecan, and osteocalcin), proteoglycan synthesis, expression of alkaline phosphatase, bone nodule formation in human IVD cells.

Lumbar spinal fusions have been performed for spinal stability, pain relief and improved function in spinal stenosis, scoliosis, spinal fractures, infectious conditions and other lumbar spinal problems. The success of lumbar spinal fusion depends on multifactors, such as types of bone graft materials, levels and numbers of fusion, spinal instrumentation,(More)
BACKGROUND Patients with lumbar spinal stenosis (LSS) are at a great risk of a fall and fracture, which vitamin D protects against. Vitamin D deficiency is expected to be highly prevalent in LSS patient, and pain is thought to have a profound effect on vitamin D status by limiting activity and sunlight exposure. OBJECTIVE To identify the prevalence of(More)
PURPOSE The cervical dynamic rotational plating system may induce bone graft subsidence, so it may cause loss of cervical lordosis. However there were few studies for alignments of cervical spines influencing the clinical results after using dynamic rotational plates. The purpose is to evaluate the effect of graft subsidence on cervical alignments due to(More)
PURPOSE To identify the incidence of new vertebral compression fractures in women after kyphoplasty and to analyze influential factors in these patients. MATERIALS AND METHODS One hundred and eleven consecutive female patients with osteoporotic vertebral compression fractures (VCFs) underwent kyphoplasty at 137 levels. These patients were followed for(More)
OBJECTIVE Metastatic spinal disease requires a multidisciplinary approach with advanced surgical techniques which improve longevity and the quality of life. The purpose of this study is to compare the surgical outcomes and perioperative complications and mortality among en bloc, debulking, and palliative surgeries in patients with spinal metastasis.
