Spinal chondrosarcomas are rare primary malignant neoplasms composed of cartilage-producing cells. They are slow-growing but locally aggressive lesions that have high rates of recurrence and progression after treatment. We provide the largest comprehensive analysis of prognostic factors, treatment modalities, and survival outcomes in patients with spinal chondrosarcoma using a large, prospectively collected national database. ⋯ Surgical resection significantly improves overall survival in patients with spinal chondrosarcoma. In those patients receiving radiation, those who receive high doses have improved overall survival compared with those who receive lower doses. Further studies into optimal radiation modality and doses are required.

Junctional Failures after Thoracolumbar Kyphosis Correction in Patients with Ankylosing Spondylitis.
We investigated the characteristics and revision rate of junctional failure after surgical correction for thoracolumbar kyphosis in patients with ankylosing spondylitis. ⋯ Of the 23 patients with junctional failure, 16 had had immature ossification of the anterior longitudinal ligament. Therefore, to prevent junctional failure, the state of ankylosis seems to be important for selecting the fusion level after osteotomy. Once junctional failure has developed, however, reoperation should be considered owing to the stress concentration at the UIV or LIV.

To analyze neurological function recovery and the impact of rehabilitation nursing in patients with cerebral stroke after treatment to aid clinical diagnosis and treatment of cerebral stroke. ⋯ Rehabilitation nursing could greatly improve the stenosis of blood vessels in patients with acute cerebral stroke and promote the establishment of collateral circulation, thereby effectively enhancing the recovery of neurological function and strengthening the ability of patients to perform activities of daily living.

Surveillance imaging is a valid management option for selected vestibular schwannomas (VS). An ideal protocol for radiologic monitoring would highlight growth-related risk factors and tailor management accordingly. This study aims to identify variables associated with the growth of sporadic VS to enhance surveillance imaging, enable early intervention, and optimize outcomes. ⋯ The factors most frequently reported as being associated with growth within the literature were size of VS at diagnosis and localization of an intracanalicular component. Greater attention should be placed on these criteria within the surveillance imaging algorithm for VS.

The aim of this study was to determine the impact of preoperative pulmonary risk factors (PRFS) on surgical outcomes after posterior spinal fusion (PSF) for adolescent idiopathic scoliosis (AIS). ⋯ Our study showed that PRF may be a risk factor for slightly longer hospital stays without higher rates of complication or unplanned readmission for patients with AIS undergoing PSF and thus should not preclude surgical management.
