In this era of imagination and technological innovation, mixed reality systems such as virtual reality (VR) and augmented reality (AR) are contributing to a wide array of neurosurgical care, from the betterment of surgical planning and surgical comfort to novel treatments and improved resident education. These systems can augment procedures that require high-level dexterity such as minimally invasive surgery and tumor excisions, as well as peripheral and neurovascular surgery. We define and compare the technological features, indications, and characterized outcomes of VR and AR systems in the context of neurosurgery through a review of the literature to date. Moreover, this review discusses the limitations of VR and AR and includes an overview of the cost-effectiveness of each of these systems. ⋯ This literature review examines recent research into VR and AR applications in neurosurgical care. The literature establishes that there are technological features, indications, outcomes, limitations, and cost-effectiveness differences between these systems. Based on ongoing and evolving applications of the VR and AR systems, the innovative potential that they make available to the future of neurosurgical patient care makes clear the need for further studies to understand the nuances between their differing technological advances.

Lumbar disc herniation (LDH) is a frequently encountered pathologic condition in orthopedic daily practice. Discectomy is considered when patients with LDH experience persistent limb or lumbar pain or neurologic deficits. Various minimally invasive techniques are available for discectomy. ⋯ Because of its long history, the TF approach seems to represent the major approach for FED, but the IL approach has numerous benefits in particular types of LDH. The present article focuses on IELD and reviews the history, surgical techniques, indications and contraindications, clinical outcomes, and complications. This review will contribute to improved understanding of IELD as an important technique in full-endoscopic spine surgery.

To identify risk factors for development of deep venous thrombosis (DVT) in patients undergoing spinal irrigation and débridement for an infection with subsequent peripherally inserted central catheter placement and to determine if chemoprophylaxis mitigates the risk of developing DVT. ⋯ Patients undergoing spinal débridement with subsequent peripherally inserted central catheter placement are at high risk for postoperative DVT. Multiple spine débridement procedures, a history of diabetes, and previous DVT are risk factors for postoperative DVT. Chemoprophylaxis does not mitigate patients' risk for postoperative DVT.

Thoracic ossification of the posterior longitudinal ligament (TOPLL) is a rare but intractable disease, and is the second leading cause of thoracic myelopathy. This study aimed to illustrate the overall knowledge structure and development trends of TOPLL, using a bibliometric analysis and newly developed visualization tools. ⋯ The study showed an upward trend with a stable rise in recent years. Japan is country with the highest productivity, not only in quality, but also in quantity. Peking University and Spine have been the largest contributors. Indeed, this study provides great insights to the growth and development of TOPLL. Moreover, it will contribute to the growth of the international frontier.

The purpose of this study is to retrospectively evaluate the clinical and surgical outcomes of a large surgical series of vestibular schwannoma from North America over 20 years. ⋯ This study represents one of the largest recently reported surgical series of vestibular schwannoma in North American literature with available long term follow-up. Facial nerve outcomes correlated with cerebellopontine angle extension, tumor volume, facial nerve stimulation threshold, facial nerve consistency, preoperative facial nerve function, and history of a prior resection. Tumor recurrence remains significantly higher after subtotal resection. We believe the data supports a continuation of a strategy of general intent of gross total resection, greatly modifiable by intraoperative findings and judgment.
