This was a retrospective study comparing dynamic contrast-enhanced magnetic resonance (DCE-MR) perfusion with digital subtraction angiography (DSA) in determining the vascularity of spinal tumors. ⋯ These data show a statistically significant correlation between CBF ratio and DSA and suggest that DCE-MR perfusion can serve as a surrogate to DSA for determining tumor vascularity in patients with extramedullary spinal metastases.

A comparative study of 2 cohort series of surgically treated patients with adolescent idiopathic scoliosis (AIS) who were retrospectively analyzed, with level III evidence. ⋯ Independent of the surgical technique used, the cervical spine had a tendency to decompensate and acquire a kyphotic sagittal profile. Constructs based on all pedicle screws have a stronger hypokyphotic effect on the thoracic spine, with a predisposition to greater decompensation of the cervical spine. Kyphotic changes in the C2-C7 sagittal alignment induced by scoliosis correction are correlated with the level of the upper-instrumented vertebra.

A population-based study. ⋯ This study established epidemiological baseline data for degenerative lumbar osteoarthritis in adults, especially for people younger than 45 years. Lumbar osteoarthritis is epidemic in Beijing and will become a more severe problem in aging society. Different populations have different features that require targeted interventions.
-
Retrospective review. ⋯ The incidence of thromboembolic complications in children was approximately 21 events per 10,000 spinal fusions. A higher incidence of VTE in children was associated with older age and certain diagnoses (congenital scoliosis, syndromic scoliosis/kyphoscoliosis, and thoracolumbar fractures). PE in children was rare and not associated with fatality.

Translation and psychometric testing. ⋯ The results confirm the successful translation and adaptation of the STarT into Chinese, with appropriate reliability and validity. Therefore, this version can be recommended for clinical and research use for Chinese patients with LBP.
