Clinical Practice in Spine Surgery: An International Survey.

Background:  The availability of diverse and sophisticated surgical options to treat spine conditions is compounded by the scarcity of high-level evidence to guide decision-making. Although studies on discrete treatments are frequently published, little information is available regarding real-world surgical practice. We intended to survey spine surgeons to assess clinical management of common spine diagnosis in day-to-day settings.

Mobile cauda equina ependymoma, case report and literature review.

The aim of this study was to describe a very rare presentation of ependymoma that can derive from intraoperative complications for surgeons and increased morbidity for the patients. Multiple cases of mobile cauda equina tumors leading to inadequate approach have been reported in the literature, however, the reports of ependymoma histology are very rare. This report describes the third adult case in recent years and a retrospective review of cases reported in the literature until today.

Frameless navigation-guided percutaneous rhizotomy of the trigeminal nerve: an appraisal of the literature.

Percutaneous rhizotomy is a cornerstone of trigeminal neuralgia treatment. The procedure is classically performed under intermittent fluoroscopic guidance. While frameless navigation has been advanced to overcome potential difficulties and risks of the technique, literature on the subject is limited, and a gap between actual use and published series is likely.

Cross my heart: ventriculoatrial shunt migration into the pulmonary arteries.

We present here a rare complication of ventriculoatrial shunt: migration of the distal catheter into both pulmonary arteries. The patient showed no cardiorespiratory symptoms. The catheter was removed by endovascular technic, the most usual procedure in these cases.
