The purpose of the present study was to investigate the diagnostic performance of F-18 fluorodeoxyglucose (FDG) positron emission tomography/computed tomography (PET/CT) for the differentiation of benign and malignant vertebral compression fractures (VCFxs) through a systematic review and meta-analysis. ⋯ The results of the present meta-analysis have shown high sensitivity and moderate specificity for F-18 FDG PET and PET/CT for differentiation of malignant VCFxs. At present, the reported data regarding the use of F-18 FDG PET for differentiation of malignant VCFxs remain limited; thus, further large multicenter studies are necessary to substantiate the diagnostic accuracy of F-18 FDG PET for the differentiation of malignant VCFxs.

Case Reports
Rare episode of cement leakage during vesselplasty in a case of vertebral compression fracture.
Osteoporosis has become an important issue owing to the increasing elderly population. It is the most common cause of vertebral compression fracture. Conservative treatment is often ineffective, whereas surgical treatment has a vital role in compression fracture. Vesselplasty is a new surgical alternative to traditional vertebroplasty and kyphoplasty. It uses a polyethylene terephthalate balloon that functions as both a vertebral body expander and a bone cement container. We present a rare but catastrophic case of cement leakage during vesselplasty resulting in devastating neurologic compromise. This case highlights the need for awareness of vesselplasty safety and the importance of using a low-temperature bone cement. ⋯ Though vesselplasty is claimed to be safe, cement leakage related to balloon rupture occurred in our case. Furthermore, thermal effects were difficult to observe during polymethyl methacrylate polymerization. Heat not only might cause irreversible complications but also might make the balloon rupture more easily.

This study aims to present a practical method to accurately diagnose ventriculoperitoneal shunt (VPS) malfunction and to detect the exact level at which the system has failed to tailor VPS revision at that level only. ⋯ The proposed algorithm is a practical, simple and minimally invasive technique to accurately diagnose VPS malfunction, identifying the exact level of system failure and allowing surgical VPS revision to be tailored, avoiding unnecessary complete system replacement.

The present study analyzed the benefits of the use of tractography in the preoperative and intraoperative scenarios. ⋯ Intraoperative navigated tractography shortened the time of awake neuro-oncological surgery and might provide help in performing complete tumor resection. Also, tractography used in the preoperative planning could be a useful tool for better prediction of complete tumor resection.

Historically, practicing neurosurgeons have been key drivers of neurosurgical innovation. We sought to describe the patents held by U.S. academic neurosurgeons and to explore the relationship between patents and royalties received. ⋯ Few U.S. academic neurosurgeons (7.8%) receive royalties and hold patents (4.7%), with an even smaller select group having a patent h-index of ≥5 (1.6%).
