Extended fusion can be performed in patients with Lenke 5C adolescent idiopathic scoliosis (AIS) with a large and relatively rigid thoracic curve. Progression of the thoracic curve is related to coronal imbalance. We aimed to determine the correlation between the upper instrumented vertebra choice and coronal balance in patients with Lenke 5C AIS. ⋯ In patients with Lenke 5C AIS, thoracic curve fusion results in better correction of the thoracic curve but no improvement in coronal balance. With TL/L fusion, a postoperative UEV tilt >5° leads to better coronal balance.

Review Case Reports
Re-recurrence of intracranial aneurysm with proximal vascular stenosis after primary clipping and secondary endovascular embolization: A case report and literature review.
It was known that a small number of patients could have intracranial aneurysm recurrences after either surgical clipping or endovascular embolization treatment. However, early recurrence within 1 month after the treatment and re-recurrence has rarely been reported before. ⋯ Re-recurrence of intracranial aneurysm could happen after initial successful treatment with surgical clipping and endovascular embolization. In addition to the patient's medical history and characteristics of the aneurysm, local vascular stenosis might also contribute to its recurrence. Close postoperative follow-up is required for these patients.

Carotid artery stenosis is frequently diagnosed through screening tests with noninvasive imaging. Because of differences noted between the various modalities, we sought to investigate our experience comparing noninvasive imaging (ultrasound, computed tomography angiography, magnetic resonance angiography) with invasive imaging (digital subtraction angiography). ⋯ Angiography should be considered the confirmatory test for degree of stenosis in certain patients before definitive surgical treatment.

During the past decades, stereotactic radiosurgery, and Gamma Knife in particular, has proved its safety and efficacy for drug-resistant classic trigeminal neuralgia. However, few large series exist using linear accelerator (LINAC) reporting long-term follow-up. ⋯ Stereotactic radiosurgery with dedicated LINAC is associated with high rates of long-term pain relief, with minimal invasiveness and rare complications. LINAC is a possible therapeutic alternative for drug-resistant trigeminal neuralgia and could be proposed to selected patients as the first intention therapy, among other surgical solutions.

Surgery for depressed skull fractures has developed over centuries to attain the consensus approaches currently used. This review outlines the last 200 years of development of surgical approaches to closed and open depressed skull fractures, fractures involving dural venous sinuses and ping-pong fractures involving infants. ⋯ However, experience has shown that each fracture category merits its own management strategies. Accepted approaches are based on observation only; there is little to no scientific evidence to support treatment for any fracture type.
