The object of this study was to examine the efficacy preoperative teriparatide treatment for increasing insertional torque pedicle screws during fusion surgery in postmenopausal women with osteoporosis.Fusion thoracic and/or lumbar spine performed 29 osteoporosis aged 65-82 years (mean 72.2 years). patients were divided into 2 groups based on whether they treated (n = 13) or not 16) before surgery. In teriparatide-treated group, received therapy as either a daily (20 μg/day, n 7) weekly...

In 2009, Santoni et al. reported cortical bone trajectory (CBT) as a method of inserting pedicle screws to obtain more solid fixation, and proposed the use with closely placed thread (cortical screws) for CBT. Since entry in CBT differs from that traditional trajectory, it is unclear whether increased strength derives specific or shape screw contact bone. Whether always required thus remains unclear. The authors therefore investigated relationship between characteristics pullout animal...

Multiple human and animal studies suggest that the upregulation of inflammatory cytokines other pain-related molecules in degenerated or injured intervertebral discs (IVDs) may cause discogenic low back pain (LBP). We previously reported macrophages IVD mice produced cytokines, but not molecules. CD14 is a monocyte marker expressed mainly by macrophages. The aim current study was to evaluate role CD14-positive cells cytokine molecule expression IVD. samples were harvested from 14 patients,...

Low back pain (LBP) is a major public health problem that adversely affects the quality of life (QOL) workers. The etiology LBP considered to be multi-factorial with individual, physical, and psychosocial factors contributing its development persistence. Although prevention in workers workplace very important, only small number studies have assessed risk epidemiology among Japanese factory who stand as part their job. This cross-sectional study investigated prevalence 691 employees conducted...

Background and Objectives: Intradiscal injection of Condoliase (chondroitin sulfate ABC endolyase), a glycosaminoglycan-degrading enzyme, is employed as minimally invasive treatment for lumbar disc herniation (LDH) represents promising option between conservative surgical intervention. Since its 2018 approval in Japan, multiple single-site trails have highlighted effectiveness, however, the effect LDH types, influences patient age, sex, etc., on success remains unclear. Moreover, data...

Wide resection of giant cell tumors at the cervical spine is sometimes extremely challenging, especially in cases where extend into nearby tissues, such as vertebral arteries, spinal cord, or nerve roots. Denosumab, a human monoclonal antibody that binds receptor activator nuclear factor κ-β ligand, reported to be effective for decreasing resorption tumor bone, but detailed progress extending tissues after treatment has not been reported.A 41-year-old man presented with neck pain. Computed...

Introduction: Patients presenting with hip diseases often have coexisting spine disorders, a condition that is termed “hip-spine syndrome.” However, few reports evaluated total spinal alignments in patients coxalgia. In this study, we retrospectively examined the relationship between several clinical and x-ray parameters of joints alignment Methods: 100 coxalgia (24 men, 76 women; average age, 60.0 years; age range, 16–88 years) were included. We following findings alignment: range motion...

There are few reports on body composition, particularly muscle mass, in patients with adolescent idiopathic scoliosis (AIS). The purpose of this study was to measure composition including mass and estimated bone AIS using bioelectrical impedance analysis (BIA) clarify the relationship between degree composition.The subjects were 210 girls (mean age 14.0 years, range 10-18 years) whose evaluated BIA (Tanita MC-780). Body index (BMI), percent fat (%BF), lean (LMI: mass/height^2), (eBoneMI:...

Abstract Sarcopenia is defined as decreasing in muscle strength and mass, dynapenia maintained mass. This study elucidated the prevalence characteristics of sarcopenia evaluate elderly spinal disorders patients. 1039 patients aged ≥ 65 years were included. We measured age, grip strength, sagittal alignment parameters, low back pain (LBP) scores health-related quality life (HR-QoL) scores. Based on previous reports, categorised into normal group: NG, pre-sarcopenia PG, DG, SG. Pre-sarcopenia,...
