Introduction. Advancements in technique and technology of minimally invasive and endoscopic spine surgery

Innovation is the lifeblood of surgery. We strive for both incremental and revolutionary improvement in patient outcomes—from ourselves in developing techniques as well as from technology that enables surgery. This issue of Neurosurgical Focus: Video is a testament to both fronts, describing the expansion of surgical techniques in more complex realms, as well as novel systems for improving our surgical success.Minimally invasive spine surgery has delivered on its promise of improved patient care—offering less muscle trauma, quicker recovery, and oftentimes fewer risks. It has also enabled new venues for surgery, which have reduced societal costs.
