The aim of this article was to analyze risk factors for secondary new vertebral compression fractures (SNVCFs) after percutaneous vertebroplasty in patients with osteoporosis. ⋯ Poor bone mineral content can be a predictive factor of SNVCFs. To prevent SNVCFs, bone cement should be injected as evenly as possible into the vertebral body. Bone cement leakage into the disc space should be avoided.

Despite the increasing number of elderly patients undergoing neurosurgical interventions, there are limited resources for preoperative assessment of frailty in this population. We investigated the association between recent history of falls and surgical outcomes for these patients. ⋯ History of at least 1 fall in the 6 months before a neurosurgical operation was associated with increased risk of discharge to a facility, readmissions, and complications in the first 30 days after discharge. History of prior falls should be taken into account during the preoperative risk assessment of neurosurgical patients.

The current study describes the impact of surgery in preventing follow-up ipsilateral transient ischemic attacks (TIAs)/strokes in an East Coast North American cohort of patients with both moyamoya syndrome (MMS) and neurofibromatosis type 1 (NF1) (MMS-NF1). ⋯ In our study of non-Asian patients with MMS-NF1, revascularization reduced stroke recurrence and deterioration of symptoms. However, more studies are warranted to further explore the role of revascularization procedures given the rarity of this disease combination.

Moyamoya angiopathy most often manifests in patients in the second and third decades of life. Although uncommon, it can also manifest later in life. We present our results in patients >50 years old with moyamoya angiopathy who were treated with surgical revascularization via either direct bypass or indirect bypass (encephaloduroarteriosynangiosis). ⋯ Although uncommon, moyamoya angiopathy can manifest in older adults. Surgical revascularization is a reasonable treatment option with good functional outcomes and an acceptable complication rate.

Deep brain stimulation within or adjacent to the subthalamic nucleus (STN) represents the most common stereotactic procedure performed for Parkinson disease. Better STN imaging is often regarded as a requirement for improving stereotactic targeting. However, it is unclear whether there is consensus about the optimal target. ⋯ This survey illustrates that most sites regarded as optimal for STN stimulation are close to each other, but there appears to be no uniform perception of the optimal anatomic target, possibly influencing surgical results. The anatomic sweet zone for STN stimulation needs further specification, as this information is likely to make magnetic resonance imaging-based target definition less variable when applied to individual patients.
