Percutaneous vertebroplasty uses the traditional method of bone cement filler to inject bone cement, which is easy to solidify, we have found a new method to delay the solidification of bone cement: low temperature ice saline bone cement, which compares the advantages of the new method and the traditional method of injecting bone cement. ⋯ Low temperature ice saline water bone cement has significant advantages in multiple vertebral fractures, relatively large amount of bone cement injected into each vertebral body and long operation time, which is more suitable for beginners.

Virtual Angioscopy (VA) has been used for vessel investigation and treatment planning in fields such as vascular surgery. To our knowledge, the utilization of VA in neurointerventional cases has not been demonstrated. ⋯ These cases demonstrate the utility of VA in endoluminal visualization of dural arteriovenous fistula that may aid in treatment planning considerations.

Total disc replacement (TDR) has become a viable alternative to anterior cervical discectomy and fusion (ACDF) for select patients. Although most comparative studies have assessed outcomes, cost differences remain largely uninvestigated. This information is critical as we move towards value-based reimbursement. To address this knowledge gap, we used time-driven activity-based costing (TDABC) to compare total intraoperative costs between the two procedures. ⋯ TDABC is a highly useful methodology for estimating differences in true costs between procedures and determining cost drivers. TDRs were associated with an additional $3,885 of total intraoperative cost as compared to ACDFs, the majority of which was driven by the cost of implants.

Existing scoring system's comparative effectiveness in identifying patients with poor prognosis (i.e., <6 months survival) has not been thoroughly explored. ⋯ This study shows that most scoring systems have low discriminative power, with only the SORG nomogram having moderate power for predicting poor prognosis. Recent and future advances in treatment, laboratory markers, and our understanding of tumor biology should be incorporated into prognostic models to improve their accuracy.

To study the effect of lumbar lordosis change and pelvic parameters on surgical outcomes such as fusion vs. non-fusion (pseudarthrosis), Adjacent Segment Pathology (ASP), and re-operation in patients undergoing 1-, 2- and 3-level PLF. ⋯ Better restoration of lumbar lordosis reduces rates of pseudarthrosis after short-segment PLF but has no association with rates of ASP.
