Personalized 3D Implants in Acetabular Reconstruction. The Future is Now

There is no doubt that total hip replacement is an effective method for treating stage 3 coxarthrosis, however, the increase in primary endoprosthetics inevitably, sooner or later, leads to an increase in revision interventions on the hip joint. Quite often, during a revision operation, a surgeon has to deal with a large bone defect in the acetabulum, dissociation of the pelvic bones, a deficiency of its walls and situations when implantation of serial components is impossible. Additive technologies using personalized 3D implants come to the rescue. The aim of the work was to clarify the role of 3D implants in modern hip arthroplasty, when the use of standard "industrial" components is impossible. The literature review included a search of available databases with an analysis of 54 relevant articles related to the reconstruction of acetabulum defects, while 32 publications cover the period over the past 5 years. Based on the literature analysis, it is concluded that non-standard, complex cases of repeated endoprosthetics are an indication for the use of 3D personalized structures, and the advantages of the technique are indicated. At present, this direction in reconstructive orthopedics of the hip joint is a promising direction. These additive technologies may become the last surgical option when the possibilities of other surgical treatment methods are exhausted.
