Randomized Controlled Trial
Comparison of PEEK and TiPEEK in Minimally Invasive Transforaminal Lumbar Interbody Fusion: a Randomized Clinical Trial.
To compare patient-reported outcomes and radiographic outcomes between using polyetheretherketone (PEEK) and titanium-coated PEEK (TiPEEK) as an interbody cage in patients who underwent minimally invasive transforaminal lumbar interbody fusion (MIS-TLIF). ⋯ The patient-reported outcomes showed significant improvements at 6- and 12-month postoperation following MIS-TLIF; the differences in those with TiPEEK versus PEEK cages were minimal with tight CIs. Fusion rates in both groups were ≥90%, with TiPEEK cages showing higher fusion rates at 6 months after the procedure.

Melanocytes are neural crest derivatives. Intracranial meningeal melanocytomas (MM) are rare tumors and the available literature is sparse for these neoplasms. This review aims to provide a detailed and comprehensive literature review of these tumors. ⋯ Complete surgical resection is the ideal treatment and adjuvant radiation is to be considered for residual/recurrent tumors. Adjuvant radiotherapy may also be prescribed despite GTR, in locations with higher RR such as CP angle and Meckel cave. Because of higher-grade transformations and delayed recurrences, long-term follow-up is required.

Awake craniotomy (AC) with brain mapping is a standard surgical technique for the excision of lesions located in eloquent areas. We aimed to assess the clinical challenges, patient experience, costs, and long-term outcomes of AC in a resource-limited setting. ⋯ In carefully selected individuals, AC with brain mapping for excision of gliomas could be a safe, effective, and affordable strategy in a resource-limited setting and can be successfully performed with satisfactory outcomes.

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.
