This forthcoming issue is of profound significance as it delves into the constantly evolving landscape of endoscopic interbody fusion—a key frontier in the realm of minimally invasive spine surgery. As we stand at the forefront of advancements in this specialized field, we recognize the crucial role this issue plays in advancing our collective understanding.

The past decade has witnessed a rapid evolution in endoscopic surgery, especially with the adoption of uniportal and biportal techniques. Traditional procedures like endoscopic discectomy and decompression have significantly changed the treatment landscape for lumbar, thoracic, and cervical spine conditions [1]. Among these developments, endoscopic lumbar interbody fusion (ELIF) stands out as a minimally invasive option that shows great promise in treating a range of spinal pathologies, such as degenerative disc disease, spondylolisthesis, and deformities [2-4].

ELIF marks a paradigm shift in spinal surgery, characterized by its approach of accessing the lumbar spine through small incisions. This technique utilizes specialized instruments and an endoscope to facilitate fusion [5,6]. The fundamental goal of ELIF is to replicate the outcomes of traditional open surgery while significantly reducing tissue trauma, minimizing postoperative discomfort, and potentially expediting patient recovery times [7,8].

However, it is crucial to acknowledge that the success and efficacy of ELIF hinge upon several critical factors, including the patient's specific condition, the surgeon's expertise, and the precise application of surgical techniques [9,10]. Given the dynamic nature of medical progress, further refinements or novel developments in ELIF or analogous minimally invasive procedures have emerged since its inception.

In this special issue, we are dedicated to fostering a comprehensive discussion that encompasses the current state, future directions, and potential challenges within the field of endoscopic interbody fusion. We are collaborating with esteemed experts and practitioners from the Taiwan Society of Endoscopic Spine Surgery, the Taiwan Society of Minimally Invasive Spine Surgery, the Japanese Society of Minimally Invasive Spine Surgery, and the Korean Society of Minimally Invasive Spine Surgery. Our goal is to provide a platform for the exchange of insights, the dissemination of the latest research findings, and the exploration of innovative techniques.

We extend a cordial invitation to researchers, clinicians, and pioneers in the field to contribute to this special issue, fostering a collective pool of knowledge that will propel the domain of minimally invasive spine surgery toward heightened precision, improved outcomes, and improved patient care.

We express our heartfelt gratitude for your invaluable contributions and dedication to advancing the frontiers of minimally invasive spine surgery. We eagerly anticipate your active participation in this enriching endeavor.
