Abstract

An analytical review of the literature on the problem of segmental spinal instability is presented. The relevance of the investigated field of spine surgery is beyond doubt. At present, a number of issues related to the definition of the concept of instability, its biomechanical basis, diagnostic criteria and treatment tactics remain debatable. The paper highlights the views of the world’s leading researchers on the understanding of various aspects of this pathology in spine surgery. The research materials were abstracts from the PubMed and Scopus databases, papers published in The Spine Journal, Spine, European Spine Journal, and in periodicals of Ukraine and Russia.
