This article is devoted to the analysis of the possibility of using additive technologies in clinical practice. The number of medical specialties that use 3D printing technologies to treat patients is increasing every year. Thanks to the emergence of high-tech qualified medical care, it is possible to carry out the most complex surgical interventions and give a person who is faced with serious diseases a high-quality and fulfilling life. The creation of a 3D model using the data of a specific patient, the use of 3D computer modeling and additive technologies have become a real breakthrough in many areas of surgery. Today, such an approach in planning reconstructive and restorative operations occupies an important position in modern medicine. The authors of the article presented their experience of using additive 3D printing technologies in clinical practice. The researchers paid special attention to the results of the use of additive technologies in the treatment of diseases of the spine: deformities, degenerative-dystrophic and oncological diseases.
