Choosing the design of the anatomically shaped vertebral implant

The article offers variants of designs of anatomically shaped vertebral implants. We assume that the vertebral implant has a foramen vertebrale. For this reason, we made the implants detachable. We have investigated two options for fixing the components of the structure: the dovetail groove and using asymmetric surfaces. Taking into account the existing medical practice, for fixing the components of the implant, we proposed the conjugation of the components with the help of asymmetric surfaces and the fastener. This is necessary to ensure the rigidity of the implant structure assembled. We have formulated criteria for the evaluation of the design, including the proximity of the weight to the weight of a natural vertebra and the possibility of resistance to the external loads. We analyzed the proposed design of the anatomically shaped vertebral implant on the basis of the formulated evaluation criteria. In order for the implant not to be rejected by the immune system and its components can grow together, it is supposed to make implants from blocks of allogenic osteoplastic material.
