The use of additive technologies in the replacement of gunshot defects of a bones

3-d technologies in modern traumatology and orthopedics have firmly taken their step in replacing bone defects of various localizations. The aim of our study was to optimize the technology of replacing gunshot extremity defects with individual autografts based on the use of 3d computer modeling, their clinical testing, evaluation of the results of application, analysis of complication and development of measures for their prevention. For the period from March 2018 to April 2021 at the Center Traumatology and Orthopedics of the Federal State Institution "The Main Military Clinical Hospital named after academician N.N. Burdenko” Russian Defence Ministry, operated on 23 (100%) patients, including 19 (82,6 %) men and 4 (17,4%) women with gunshot defects or extremity bones. Tested and introduced into everyday activities on the basis o the Center Traumatology and Orthopedics, the used 3d substitution in the treatment gunshot defects or extremity bones, not previously used in the Russian Federation, showed good results in the early postoperative period. Replacement of bone defects with implants made of bone-substituting material it has proven itself as a reliable method. The use 3d technologies allows to model individual implants of any complexity, thereby most optimally approach the treatment of a particular patient, as anatomically as possible replace a gunshot bones defects and achieve early recovery functions of the damaged extremity.
