Image guidance has transformed minimally invasive spine surgery (MISS), allowing for safer procedures without excessive bony exposure and reducing radiation exposure for the surgical team. Robotic platforms have enhanced the benefits of navigation by providing high precision and accuracy. Here we describe a case series to demonstrate the accuracy and low complication rates of real-time image-guided robotic-assisted (RA) MISS at a tertiary referral center. In addition, we performed a narrative review on how robotics and navigation facilitate MISS. ⋯ Robotic platforms have further enhanced navigation benefits by providing high precision and accuracy, with low complication rates.

Anterior lumbar interbody fusion (ALIF) is an established surgical approach for spinal fusion, offering distinct advantages in restoring lumbar lordosis, indirectly decompressing neural elements, and facilitating high fusion rates because of the increase in the fusion surface area. Traditionally, ALIF is performed with the patient in a supine position, necessitating repositioning for additional posterior interventions, which increases operative time, anesthetic time, and complexity. The recent development of single position lateral ALIF (SPL-ALIF) enables anterior and posterior access without repositioning, enables gravity facilitated retroperitoneal access, and optimizes surgical efficiency, particularly in cases necessitating multilevel anterior column fusion. ⋯ The technique may be less effective in cases requiring direct decompression or in patients with complex vascular anatomy or extensive retroperitoneal scarring. These challenges necessitate careful patient selection to optimize outcomes and minimize intraoperative risks. Future studies are warranted to validate the clinical benefits of SPL-ALIF, particularly concerning fusion rates, patient-reported outcomes, and complication profiles, thereby solidifying its role in the evolving landscape of minimally invasive spine surgery.

Single-position prone transpsoas (PTP) lateral interbody fusion has been proposed as an alternative to lateral lumbar interbody fusion performed in the lateral decubitus position. The advantages to this single-position technique include facilitating segmental lordosis, obviating the need for repositioning for posterior instrumentation, and providing access for posterior decompression. ⋯ This review provides a detailed technical description of the PTP technique at L4-L5. In addition, we provide technical pearls aimed at improving surgical ergonomics, workflow, and safety.

Beyond Pedicle Screw Placement: Future Minimally Invasive Applications of Robotics in Spine Surgery.
Advancements in spine surgery have dramatically enhanced minimally invasive techniques, prominently through integrating robotic systems. Although pedicle screw placement remains the most widespread application of this technology, new developments are emerging to create innovative future avenues for these tools. ⋯ We also discuss the potential for integrating artificial intelligence and augmented reality with robotic systems. If the current trajectory of research and innovation continues, there is promise in creating fully autonomous robotic systems that can revolutionize spine surgery by processing, planning, and performing procedures without heavy reliance on the surgeon.

Neuromonitoring in minimally invasive spine surgery (MISS) provides real-time feedback to surgeons and enhances surgical precision for improved patient safety. Since the 1970s, established techniques like somatosensory evoked potentials, motor evoked potentials, and electromyography have been integrated into spine surgeries, significantly reducing the risk of neurological complications. These neuromonitoring modalities have been crucial, particularly in complex procedures with limited direct visualization. ⋯ This review explores the historical development, current techniques, clinical outcomes, and future directions of neuromonitoring in MISS. It emphasizes the critical role of these technologies in enhancing surgical outcomes and patient care. As MISS continues to evolve, adopting next-generation neuromonitoring systems, including artificial intelligence and machine learning, will play a pivotal role in advancing the efficacy and safety of spine surgeries.
