In recent years, the transition to personalized medicine, which takes into account the individual anatomical features of patients, has become increasingly relevant. Data from computed tomography, digital design methods, and additive technologies are used to create three-dimensional models of patients' bone structures. These models allow for precise positioning and design of implants using specialized engineering software. Medical specialists formulate technical specifications and approve the resulting models. The article discusses the necessity of developing domestic information systems for joint implant design, considering the limited functionality of existing solutions and their dependence on foreign products. A mathematical model of the stress- strain state of an elastic body and a software complex for modeling, including a graphical user interface, are presented. The stages of creating a solid model from a surface representation, setting boundary conditions, and performing strength calculations using the finite element method are examined. Modeling examples demonstrate the use of developed methods for designing implants for craniotomy patients. The result is a system that improves the quality of medical services and the strength characteristics of implants through the implementation of digital design methods adapted to the individual anatomical features of each patient. Additionally, the application of Color Picking technology for interactive selection of model facets is considered, which enhances the accuracy of setting boundary conditions and optimizes the implant design processes
