For 10 years, we studied the diagnostic role of three-phase bone scintigraphy (3-f BS) in the early prognosis of paraendoprosthetic complications in patients with degenerative-dystrophic and infectious-inflammatory diseases of the hip and knee joints. Using 3-f BS, the kinetic radionuclide parameters of inclusion and distribution of radiopharmaceutical (RP) in the projection of affected joints were evaluated. It was determined that the kinetics of osteotropic RP in the foci of fixation of affected joints in infectious and inflammatory processes is characterized by the predominance of retention and specific accumulation of the drug in the early and delayed static phase of 3-f BS in comparison with foci of fixing RP in degenerative-dystrophic lesions, which correlates with the differences destructively-reparative processes in them.According to the results of the analysis of the kinetic parameters, a radionuclide model of the dynamics of inclusion and distribution of RP in septic and aseptic joint lesions has been developed.
