Approximately 10% of all cancer patients develop spinal metastases. When a symptomatic compression fracture occurs without associated deformity or neurologic deficit, it can be treated with kyphoplasty with or without radiofrequency ablation (RFA). Treatment with kyphoplasty is well established but does not address the underlying oncologic disease. ⋯ The results suggest that the addition of RFA to kyphoplasty may reduce local tumor recurrence while providing similar pain relief benefits. The extrapolation of this added benefit to metastases from other primary cancers should be examined in future studies.

Classic randomized controlled trials (RCTs) form the cornerstone for medical guidelines and protocols. However, in neurosurgery, RCTs are not always applicable to everyday clinical practice. Pragmatic controlled trials aim to incorporate real-life data with the preservation of the methodologic quality. This study is a systematic literature review of all pediatric neurosurgical RCTs published between 2000 and 2020 and an analysis of their pragmatism. ⋯ Pediatric neurosurgical RCTs scored reasonably well on overall pragmatism. In the future, there will be a greater need for pragmatic controlled trials in pediatric neurosurgery to bridge the divide between real-life data and reliable methodological quality. There is an opportunity to develop further applications of pragmatism tailored to surgical interventions.

With the advent of personalized and stratified medicine, there has been much discussion about predictive modeling and the role of classical regression in modern medical research. We describe and distinguish the goals in these 2 frameworks for analysis. ⋯ Both classical regression and predictive modeling have important roles in modern medical research. Understanding the distinction between the 2 frameworks for analysis is important to place them in their appropriate context and interpreting findings from published studies appropriately.

Traumatic brain injury (TBI) is a risk factor for venous thromboembolism (VTE). The risk of VTE after decompressive craniectomy (DC) and its effects on the outcomes are unknown. We assessed the incidence of VTE, associated risk factors, and effects on the outcomes. ⋯ Our study showed an independent association between DC and an increased risk of VTE for patients with severe TBI. The development of VTE after DC increased the proportion of poor outcomes, prolonged the length of stay, and increased the hospitalization costs. Older patients with obesity, an electrolyte imbalance, chronic lung disease, spine injury, and infections were at a greater risk of VTE after DC. These risk factors could help in considering VTE prophylaxis for these patients.
