The development of spine neurosurgery raises some questions concerning the methodology, practical significance, treatment and diagnosis of spinal diseases. In this regard, we inevitably turn to the methods of philosophical knowledge as a basis for analysis and synthesis of scientific information. This approach allows you to avoid mistakes in practice, which can have negative ethical and socio-economic consequences for society. Some controversial issues of spine surgery are discussed in the manuscript. Advisability of syndromic approach in the treatment of spine diseases, determining the length of spine fusion for injury, prediction of postoperative segmental instability due to osteoporosis and extrapolation of the principles of spine fusion surgery to arthroplasty are considered through the prism of philosophical categories.
