In Brief Study Design. Prospective multicenter study. Objective. To identify radiographic or magnetic resonance (MR) images of fresh vertebral fractures that can predict a high risk for delayed union nonunion osteoporotic (OVFs). Summary Background Data. Vertebral body are the most common in osteoporosis patients. Conservative treatments typically chosen OVFs, and associated back pain generally subsides within several weeks with residual persistent deformity body. some patients, OVF healing...
A retrospective study.Purpose: This study aimed to determine the impact of increased Hounsfield unit (HU) values for metastatic spinal lesions measured via computed tomography on overall survival patients with non-small-cell lung cancer (NSCLC) and identify factors associated HU in lesions.Overview Literature: Previous studies have underscored utility as a marker treatment response bone lesions.However, no prior explored relationship between changes NSCLC.Methods: included total 85 2016...
Prospective multicenter study.To examine whether initial conservative treatment interventions for osteoporotic vertebral fractures (OVF) influence patient outcomes.OVFs have been described as stable spinal injuries and, in most cases, are managed well with treatment. However, systematic treatments OVF not clearly established.A total of 362 patients (59 males and 303 females; mean age, 76.3 yr) from 25 institutes were enrolled this clinical study. All the treated conservatively without any...
While bracing is the standard conservative treatment for acute osteoporotic compression fracture, efficacy of different brace treatments has not been extensively studied. We aimed to clarify and compare preventive effect on deformity vertebral body other clinical results in this patient cohort. This multicenter nationwide prospective randomized study included female patients aged 65⁻85 years with one-level fractures. assigned within four weeks injury either a rigid-brace or soft-brace...
Lumbar spinal stenosis (LSS) is one of the most frequent causes low back pain and gait disturbance in elderly. Ligamentum flavum (LF) hypertrophy main pathomechanism LSS, but reason for its occurrence not clearly elucidated. In this study, we established a novel animal model intervertebral mechanical stress concentration investigated biological property LF. The LF with showed degeneration elastic fibres disruption cartilage matrix increase, which are similar to findings hypertrophied from...
A multicenter, prospective, single-arm, intervention study.The aim of this study was to investigate efficacy balloon kyphoplasty (BKP) for acute osteoporotic vertebral fractures (OVFs) in patients with poor prognostic factors.The indications BKP remain unclear. Characteristic magnetic resonance imaging (MRI) findings (high-intensity or diffuse low-intensity area fractured vertebrae on T2-weighted images) were reportedly predictive delayed union.This enrolled 106 MRI who underwent within 2...
Study Design. Prospective cohort study. Objective. To characterize a patient population with nonunion after acute osteoporotic vertebral fractures (OVFs) and compare the union groups to identify risk factors for nonunion. Summary of Background Data. While OVFs are most common type fracture, predictive value clinical assessment at 48 weeks OVF has not been extensively studied. Methods. This prospective multicenter study included female patients aged 65 85 years one-level compression...
Study design. Cross-sectional study. Objective. Validate the diagnostic accuracy of a deep-learning algorithm for cervical cord compression due to degenerative canal stenosis on radiography. Summary Background Data. The diagnosis myelopathy is often delayed, resulting in improper management. Screening tools suspected would help identify patients who require detailed physical evaluation. Materials and Methods. Data from 240 (120 with magnetic resonance imaging 120 age sex-matched controls)...
A 24-year-old woman with Graves' disease treated methimazole for 4 years, developed recalcitrant ulcers on the lower legs. Histological studies demonstrated vasculitis in deep dermal vessels accompanied by C3 deposition. Laboratory investigation revealed lupus-like abnormalities (leucocytopenia, positive antinuclear and antidouble strand (ds) DNA antibodies, ANCA). The leg dramatically improved after was withdrawn. In addition, leucocytopenia immunological soon laded. Although syndrome is...
In Brief Study Design. An experimental animal study to achieve posterolateral intertransverse process spine fusion with recombinant bone morphogenetic protein in combination a new delivery system. Objective. To evaluate the efficacy of synthetic biodegradable bone-inducing material containing human protein-2 (rhBMP-2) as bone-graft substitute for rabbit model. Summary Background Data. rhBMP-2, powerful cytokine, has been used graft animal-derived collagen spinal models. However, minimum dose...
