Augmented reality (AR) is a technology that allows digital information to be superimposed onto a user's view of the real world, thereby enhancing the user's experience of a given real-world scenario. As recent advances in AR technology have made it more available for a variety of applications, hospitals and doctors have begun to test its utility in the operating room. AR technology allows surgeons to supplement their view of the operative field with useful patient-specific information for which they might otherwise need to turn their attention away from the task at hand. ⋯ The field of spine surgery is uniquely positioned to benefit from AR, given the extent to which many spine surgeons already rely on intraoperative navigation techniques for certain surgical tasks, including pedicle screw and interbody device placement. In this review, we outline the origins and history of AR in spine surgery and cover the current state of the literature regarding the applications, benefits, and drawbacks of its use within the field. Lastly, we speculate as to the future of AR in spine surgery and propose which gaps in knowledge must be addressed before the technology enjoys a degree of adoption on par with currently available intraoperative navigation techniques.

The application of minimally invasive spine surgery (MISS) in degenerative spine disease and deformity has seen rapid growth in the past 20 years. Building on this experience, such methods have been adopted into spine oncology in the past decade, particularly for metastatic disease. The impetus for this growth stems from the benefits of surgical decompression combined with radiation treatment in patients with metastatic disease in conjunction with the need for less morbid interventions in a patient population with limited life expectancy. ⋯ The implementation of navigation and robotic capabilities has transformed MISS by streamlining surgery and further reducing the surgical footprint while laser ablation, endoscopy, and robotic surgery hold the potential to minimize the surgical footprint even further. MISS for intradural tumors is commonly performed, while the role for other primary tumors has yet to be defined. In this article, we describe the evolution of and indications for MISS in spine oncology through a retrospective literature review.

The transforaminal lumbar interbody fusion remains one of the most common surgical techniques used for spinal arthrodesis. Spine surgery over the last three decades has increasingly emphasized approaches that reduce tissue trauma, iatrogenic injury, and perioperative morbidity. ⋯ In this paper, the authors review the techniques and considerations underlying visualization within both methods, as well as provide summary of a hybrid system incorporating the advantages of both. Minimally invasive transforaminal lumbar interbody fusion modalities must be selected in accordance with patient factors to achieve optimal outcomes.

Symptomatic thoracic disc herniation (TDH) is relatively uncommon, and surgical management poses significant challenges owing to restricted anatomic corridors, limited space within the spinal canal, tenuous blood supply, and proximity to vital organs and vasculature. Calcified TDH adds further complexity, necessitating meticulous preoperative planning to determine the safest and most effective approach. ⋯ However, research specifically focusing on the efficacy of this technique remains limited. This narrative review examines the existing literature on the lateral retropleural approach, discussing reported outcomes, technical considerations, and potential challenges.

Thoracolumbar minimally invasive spine surgery (MIS) has become widely adopted over the past two decades. MIS cervical fixation has lagged behind, largely because of complex and variable cervical spinal anatomy. Traditional open spine fixation techniques are associated with high fusion rates but are plagued by significant approach-related morbidity. ⋯ With the incorporation of new enabling navigation technologies, this technique is feasible, reproducible, and safe. In addition, these procedures have provided unique solutions for approaching cervical pathology in line with currently accepted MIS principles of the thoracolumbar spine. This review article discusses current minimally invasive posterior fusion strategies with a description of the technique and case demonstrations.
