[Several indicators of oxidative processes in fractures of the long bones].

The authors have observed 55 patients with fresh fractures, with disturbances in consolidation (delayed consolidation, non-union of fractures, false joints) and with defects of diaphyses of the long bones. In the fracture area the dynamics of oxidation-reduction potential (ORP) was studied and volarographic investigations (determination of the volumetric speed of the local blood flow by hydrogen, a test with oxygen load) were carried out. Certain correlation between the quantity and the dynamics of the values under study and the state of the consolidation process was established. Coincidence of the dynamics of ORP and the local blood flow, presence of the quantity of volumetric speed of the local blood flow of 25-30 ml/min per 100 g of tissue with rather high ORP and a positive test under oxygen load in the polarographic study were prognostically favourable. The applied methods allow to control the course of the process of consolidation of the fragments and to a certain extent prognosticate the results of treatment of the patients with fractures of the long bones.
