Minimally invasive spine surgery: systematic review.

Minimally invasive procedures in spine surgery have undergone significant development in recent times. These procedures have the common aim of avoiding biomechanical complications associated with some traditional destructive methods and improving efficacy. These new techniques prevent damage to crucial posterior stabilizers and preserve the structural integrity and stability of the spine. The wide variety of reported minimally invasive methods for different pathologies necessitates a systematic classification. In the present review, authors first provide a classification system of minimally invasive techniques based on the location of the pathologic lesion to be treated, to help the surgeon in selecting the appropriate procedure. Minimally invasive techniques are then described in detail, including technical features, advantages, complications, and clinical outcomes, based on available literature.
