PREDICTION OF PARANENDOPROSTHETIC COMPLICATIONS OF PATIENTS WITH THE PATHOLOGY OF HIP AND KNEE JOINTS OF VARIOUS GENESIS

Abstract

Relevance. The issue of degenerative-dystrophic lesions of the hip and knee joints is becoming urgent in Ukraine. To date, in order to visualize degenerative-dystrophic and infectious-inflammatory lesions in the treatment and diagnostic process, the three-phase bone scintigraphy method is actively used, with the help of which it is possible to obtain a quantitative characteristic of metabolic changes and the morphological status of the organism. Objective. To determine the specific radionuclide parameters of three-phase bone scintigraphy for optimizing the prediction of paraendoprosthetic complications in pathological lesions of hip and knee joints of different genesis. Material and methods. The retrospective analysis of 455 patients with diseases of hip and knee joints of various genesis (including 274 women and 181 men), aged from 17 to 85 years, was conducted in the work. All patients underwent three-phase bone scintigraphy according to the standard protocol. Results. In the early static phase of bone scintigraphy, a gradual increase in the percentage of inclusion and distribution of radiopharmaceutical in degenerative-dystrophic and infectious-inflammatory foci is observed. The increase in accumulation of the indicator in the delayed static phase in the infectious-inflammatory foci of deforming osteoarthrosis is caused by an increase in the intensity of blood flow in the angiographic phase, which indicated the intensification of the arterial blood supply of such foci, due to active inflammation, exposure to an infectious agent or increased osteoblastic activity. Conclusion. The determination of the kinetic parameters of bone scintigraphy and the application of the radionuclide model of «dual time point imaging» contribute to the early detection of paraendoprosthetic complications in the postoperative period, the reduction of the number of revision procedures and the reduction in the duration of rehabilitation and recovery measures after endoprosthetics.
