title: [Evaluation of the results of the treatment of pseudarthroses of the forearm bones based on the analysis of the data of radionuclide studies].
abstract: The work is based on the analysis of the results of radionuclide examination and treatment of 14 patients with ununited tractures and pseudoarthroses of the forearm bones. Treatment was accomplished by means of external fixation apparatuses which in comparison with intramedullary and epiosseous osteosynthesis provide a better stability of the site of bone injury and create ortimal biomechanical conditions for consolidation of ununited fractures and pseudoarthroses of the forearm bones. Radionuclide examination was conducted before the treatment to determine the initial activity of reparative regeneration in the zone of the pseudoarthrosis and the adjacent healthy regions, 2-3 weeks after perosseous osteosynthesis when the bone fragments were reduced and the compression or distraction regimen was established, and before removal of the apparatus when consolidation of the pseudoarthrosis was demonstrated radiologically. This made it possible to control the activity of reparative regeneration during treatment and to introduce corrections, if necessary. The radionuclide method is preferable to the radiological method in the intermediate stages of treatment not only because of the lesser exposure of the patient to radiation but because of the higner informativeness.
