To investigate the external validation and scalability of four predictive models regarding new vertebral fractures following percutaneous vertebroplasty. ⋯ The external validation of four models demonstrated that the predictive model proposed by Zhong et al. in 2016 exhibited superior external generalization capabilities.

Narrative Review. ⋯ We have established a new instrumentation algorithm that should be taken into consideration for patients undergoing MSTS. It serves as an important guide for surgeons treating MSTS, with the continuous evolvement of our treatment capacity in MSD.

Review
A critical appraisal of clinical practice guidelines on surgical treatments for spinal metastasis.
As an important treatment for spinal metastasis, surgery has strict applicable conditions. Although various organizations have formulated different guidelines on surgical treatment for spinal metastasis (SM), there are certain differences in the content, standardization and quality of the guidelines and it is necessary to make a critical appraisal of them. We aim to systematically review and appraise the current guidelines on surgical treatments of SM and summarize the related recommendations with the quality evaluation of supporting evidence, as to provide a reference for the standardization of surgical treatment plans, and help clinical front-line medical workers can make safe and effective clinical decisions faster. ⋯ Most of the guidelines do not provide clear criteria for surgical application and provide more of a basic framework. The level of evidence for these surgical recommendations ranges from LOE B to D, and almost all guidelines recommend vertebroplasty and kyphoplasty, but for palliative and more aggressive surgery, which recommended to personalize specific surgical strategies with multidisciplinary collaboration.

Fatty infiltration (FI) of the paraspinal muscles may associate with pain and surgical complications in patients with lumbar spinal stenosis (LSS). We evaluated the prognostic influence of MRI-assessed paraspinal muscles' FI on pain or disability 2 years after surgery for LSS. ⋯ Preoperative FI of the paraspinal muscles on MRI showed statistically significant association with postoperative NRS leg pain but not with ODI or ZCQ.

Preoperative elastoplasty could be an alternative strategy for treating aggressive vertebral hemangiomas (VHs) in frail patients needing for spinal cord decompression, combining the advantages of embolization and vertebroplasty. ⋯ When facing highly bony erosive VH encroaching the spinal canal, VK100 combines the advantages of embolization and vertebroplasty especially in elderly patients, permeating the whole VH's angioarchitecture, significantly reducing tumor.
