There are few reports on the robot-assisted percutaneous kyphoplasty (PKP) for osteoporotic vertebral compression fractures (OVCF), and we aimed to explore the learning curve of the robot-assisted PKP for treating OVCF. ⋯ The puncture accuracy of robot-assisted PKP for treating OVCF does not change with the increase in the number of operations. The total operation time and robotic-assisted operation time decreases with the increase in the number of cases.

Review Case Reports
Filum terminale arteriovenous fistula in association with degenerative lumbrosacral spinal canal stenosis: Report of three cases and review of the literature.
Filum terminale arteriovenous fistulas (FTAVFs) are rare, and the pathogenesis of these fistulas remains unclear. They may be either congenital or acquired in origin. The authors report 3 cases of FTAVFs in association with severe spinal canal stenosis. The authors also review literature of FTAVFs associated with spinal canal stenosis. ⋯ Our 3 case reports may provide additional evidence supporting an acquired etiology of FTAVFs, probably secondary to the severe central canal stenosis. From our review, the level of the fistulas in most patients is correlated with the level of spinal canal stenosis. The authors preferred the concomitant surgical treatment by performing decompressive laminectomy and obliteration of the fistula in the same surgical session.

Case Reports
Treatment of Extracranial Vertebral Artery Aneurysm with Flow Diversion: A Case Report.
Aneurysms of the extracranial vertebral artery are rare, and the treatment options are not standardized. We present a case of an extracranial vertebral artery aneurysm treated with flow diversion. ⋯ Flow diversion is a simple and promising treatment option for a V3 segment aneurysm. Postoperative asymptomatic partial in-stent stenosis is tolerable.

The minipterional approach (MPTa) has been widely accepted as a minimally invasive technique in the treatment of anterior and middle cranial fossa lesions. However, this craniotomy does not facilitate exposure of the distal sylvian fissure or wide sylvian dissection. We have described a modification of the MPTa, the extended minipterional approach (eMPTa), which results in improved access to the distal sylvian fissure with minimal additional bony removal. We have defined the ideal posterior landmark for this craniotomy, the preauricular line, using an anatomic cadaveric study. ⋯ The eMPTA offers improved access to the sylvian fissure, allowing for wider fissure splitting and only requiring extension of the posterior limit of the MPT craniotomy up to the preauricular line. This could allow for improved freedom of movement deep in the sylvian cistern and potentially expand the indications of the MPTa.

The article uses ultrasound imaging standard section to examine the fetal central nervous system (CNS) in early pregnancy, combined with ultrasound imaging in the diagnosis of fetal CNS malformation in the middle and late pregnancy, to determine the feasibility of ultrasound imaging in the detection of CNS abnormalities in the first trimester of the fetus. ⋯ The positive cases detected in early pregnancy were severe malformations of the CNS. The diagnosis of other CNS malformations in the fetus needs further study.
