Operative treatment of adolescent idiopathic scoliosis (AIS) with posterior spinal fusion aims for three-dimensional correction of coronal curve and thoracic kyphosis. Our aim was to compare two different designs of asymmetrical rods in adolescents who underwent a posterior spinal fusion with pedicle screw instrumentation for AIS with an emphasis on thoracic kyphosis restoration. ⋯ There are no significant differences in the coronal or sagittal deformity restoration in adolescent patients who underwent a posterior spinal fusion with sagittal reinforced rods and beam-like rods for adolescent idiopathic scoliosis.

In 2019, we highlighted the disparities in scientific production between high-income countries (HICs) and low- to middle-income countries (LMICs) by emphasizing how scientific research was underrepresented in the latter. The present study aimed to investigate research productivity in neurosurgery of low-income countries (LICs) and LMICs for the years 2018-2020 and to compare it with the results of our previous study for 2015-2017. ⋯ There is growing consensus in the neurosurgical scientific community that the dissemination and analysis of epidemiologic and clinical data from developing countries can provide guidelines and practical suggestions worldwide. However, our study shows that the number of neurosurgical articles published by low-income countries in 2018-2020 remained at approximately 5% of the total, resulting in a negative impact on the process of globalization.

Case Reports
Traumatic pseudoaneurysm of the occipital artery treated with open surgical ligation: 2-Dimensional Operative Video.
Scalp pseudoaneurysms occur most commonly because of trauma and are often in the superficial temporal artery due to the lack of soft tissue coverage between skin and bone, making it more vulnerable anatomically.1,2 Pseudoaneurysms of the occipital artery (OA) also occur but are extremely rare.2-4 An 80-year-old man presented with scalp bleeding and a small left-sided posterior scalp laceration after a fall and head strike 10 days prior. He was admitted and during his 2-week hospital stay, the occipital laceration continued to rebleed (Video 1). He developed a 2-cm pulsatile ulcerative mass with central necrosis on the left nuchal ridge. ⋯ The clinical presentation of this case was unique because this patient had an ulcerated lesion with central necrosis overlying the pseudoaneurysm. Endovascular management alone would not address the open lesion, which is at high risk for infection. The risk of infection would increase after embolization of the occipital artery, causing further necrosis of the tissue.

An extensive spinal epidural abscess is a devasting infection of the multiple-level epidural space. Emergent surgical decompression is required to remove the abscess and decompress the affected spinal cord. This study evaluated the efficacy of unilateral laminotomy for bilateral decompression (ULBD) in the treatment of extensive spinal epidural abscesses. ⋯ As a minimally invasive technique, ULBD is a safe and effective treatment for extensive spinal epidural abscesses in critically ill patients. Moreover, the use of an ultrasonic bone curette not only safely accelerates over-the-top decompression but also flushes the epidural abscess with copious amount of cold saline.

Intracerebral hemorrhage (ICH) is the second most common subtype of stroke but is associated with greater rates of disability or mortality. One of the factors of a poor prognosis is large hematoma volume. The MISTIE III trial with the aim of decreasing clot size showed that the greater the ICH reduction, the higher likelihood of lower mortality without a net increase in the proportion of patients with severe disability. Our aim is to describe our experience with treating selective patients with ICH per the MISTIE trial protocol in a university hospital in Argentina during 4 years. ⋯ The procedure can be carried out safely in Latin American centers that have experience in managing neurocritical patients.
