Assessment system of design parameters and functionality of metal vertebral body endoprosthesis for anterior interbody fusion
Abstract
The article presents the estimates of the parameters of endoprosthesis, which allows to determine the advantages and dis- advantages of various implants as systems for reconstruction and stabilization of the spinal motion segment, and creating conditions for bone fusion of vertebrae adjacent to the resected one. The results obtained in studying characteristics of the cages allow their division into 4 groups depending on the combination of features necessary for performing surgeries on the anterior and middle columns of the spine. Based on these data, the authors developed a design of vertical cylindrical telescopic endoprosthesis LAS. The above information increases the possibility of an objective evaluation of the mechanisms of probable postoperative complications and may facilitate the selection of the optimal design, taking into account characteristics of the clinical situation in each particular case.
