STUDY DESIGN Large cohort study of volunteers aged over 50. OBJECTIVE To investigate influence of age and sex on cervical sagittal alignment among volunteers aged over 50. SUMMARY OF BACKGROUND DATA Few large-scale studies have described normative values in cervical spine alignment regarding age and sex among volunteers aged over 50. METHODS The study(More)
T1 pelvic angle (TPA) and global tilt (GT) are spinopelvic parameters that account for trunk anteversion and pelvic retroversion. To investigate spinopelvic parameters, especially TPA and GT, in Japanese adults and determine norms for each parameter related to health-related quality of life (HRQOL). Six hundred and fifty-six volunteers (262 men and 394(More)
STUDY DESIGN Retrospective case series. PURPOSE To investigate the relationship between tumor location and clinical characteristics. OVERVIEW OF LITERATURE Hemangioblastoma is a rare disease that develops in the central nervous system. Magnetic resonance imaging (MRI) is useful to evaluate hemangioblastomas. Hemangioblastoma's location is designated as(More)
STUDY DESIGN A retrospective study. OBJECT To investigate the rate of lumbosacral junction complication after long corrective spinal fusion for degenerative kyphoscoliosis cases with different lower instrumented vertebra (LIV) of L5, S1 (non-iliac group), and ilium (iliac group). SUMMARY OF BACKGROUND DATA In long spinal fusion, high mechanical stress(More)
STUDY DESIGN Retrospective case series. OBJECTIVE The present study aimed to determine the characteristics of patients with adult spinal deformity (ASD) with a discrepancy between standing and walking postures. SUMMARY OF BACKGROUND DATA Standing radiographic parameters are typically used to evaluate patients with ASD. Patients with ASD with relatively(More)
STUDY DESIGN A retrospective study. OBJECTIVE We investigated the prevalence of iliac screw loosening and determined risk factors after adult spinal deformity (ASD) surgery. SUMMARY OF BACKGROUND DATA Lumbosacral fixation is crucial to maintain optimal sagittal alignment. Iliac screws are commonly placed to provide protection for sacral pedicle screws.(More)
The objective of this study was to investigate if cows milked twice per day have more dif®culty lying down and getting up and spend less time lying than cows milked three times per day. Seventeen cows of the Swedish Red and White Cattle Breed were studied, seven of which were milked twice daily (2M) and ten were milked three times (3M) daily. They were kept(More)
STUDY DESIGN A retrospective study of surgical outcomes of adult spinal deformity (ASD) cases. OBJECTIVE The aim of the study was to investigate the effects of high T1 slope (T1S) on surgical outcomes in patients with ASD. SUMMARY OF BACKGROUND DATA Few studies have evaluated the surgical outcomes of patients with ASD with cervical deformities. (More)
STUDY DESIGN This investigation consisted of a cross-sectional study and a retrospective multicenter case series. OBJECTIVE This investigation sought to identify the ideal lumbar lordosis (LL) angle for restoring an optimal pelvic tilt (PT) in patients with adult spinal deformity (ASD). SUMMARY OF BACKGROUND DATA To achieve successful corrective fusion(More)
STUDY DESIGN Retrospective study OBJECTIVE.: To determine the prevalence of loss in fixed segment alignment after surgical correction of adult spinal deformity (ASD) and identify associated risk factors. SUMMARY OF BACKGROUND DATA Altered fixed segment alignment influences global spinal alignment; however, associated risk factors have not been determined.(More)
