One of the most common reasons for poor patient outcomes and revision surgery in spinal fusion is hardware failure. Screw loosening or pullout occurs in up to one-quarter of all cases. It is known that even small screw-rod misalignments can cause significant mechanical overloads during rod fixation, which can result in hardware failure. To address this crucial surgical step, a novel augmented reality-assisted software was developed to generate custom rod templates that are precisely adapted to the individual patient. ⋯ The augmented reality-assisted software is intended to give surgeons access to patient-specific intraoperative real-time data, helping them in bending rods that are more precisely adapted to the individual patient compared with the freehand technique.

Case Reports
ISOLATED INTRAVENTRICULAR NEUROCYSTICERCOSIS: AN ATYPICAL PRESENTATION OF A COLLOID CYST.
Neurocysticercosis is a condition characterized by the presence of Taenia solium (larval stage: Cysticercus cellulosae) in the brain and is classified as a tropical disease. Although it was previously uncommon in Europe, the number of cases has been increasing over the past decade. ⋯ Anatomopathologic analysis confirmed the presence of a C. cellulosae larva. It is crucial not to overlook or misdiagnose isolated intraventricular neurocysticercosis because it can lead to complications such as delayed diagnosis and dissemination of the cyst.

Orbital cavernous hemangiomas are the most common adult benign vascular orbital neoformation, representing 5%-15% of all orbital masses, and may involve the extraconal or intraconal space.1 According to the International Society for the Study of Vascular Anomalies, orbital cavernous hemangiomas should be classified as low-flow nondistensible venous malformations and are characterized by slow growth, generally 0.2 cm3/year.2,3 For these characteristics, complete surgical resection is necessary for symptomatic patients or in case of significant volumetric increase in its size.4Video 1 demonstrates the cryo-assisted removal of an intraconal orbital hemangioma (22 × 26 mm) located in the superior-lateral aspect of the right orbit in a 55-year-old woman. The patient presented with right exophthalmos and diplopia on right lateral gaze. The lesion was completely removed using a right lateral orbitotomy combined with a superior eyelid endoscopic-assisted approach. ⋯ Exophthalmos resolved postoperatively, without any cosmetic sequelae or visual impairment. Magnetic resonance imaging performed 8 months after surgery demonstrated excellent surgical outcomes, with complete resolution of the exophthalmos and without evidence of persistence of disease. A multidisciplinary approach, involving different specialists familiar with orbital anatomy and physiology, is fundamental in the management of these rare orbital pathologies.

Review
Global Epidemiology of Pediatric Traumatic Spine Injury: A Systematic Review and Meta-Analysis.
Traumatic spine injury (TSI) leads to significant morbidity and mortality in children. However, the global epidemiology of pediatric TSI is currently unknown. We conducted a systematic review and meta-analysis to estimate the global incidence of pediatric TSI and the burden of cases. ⋯ Pediatric TSI represents a large healthcare burden globally. Interventions targeting both injury prevention and strengthening of neurosurgical capacity, especially in low resource settings, are needed to address this global health challenge.
