ABSTRACT

The results of operative treatment of 8 patients was analyzed, in whom the lower extremity amputation on the upper third of the shin was performed for severe stage of the ischemic foot contacture. Operative interventions is expedient to perform in a specialized stationary, were exists possibility of further prosthesis. It is necessary to perform the extremity amputation in a residual period of the foot ischemic contracture, when operations for restoration of the sole sensitivity are nonperspective as well as in presence of severe trophic disorders on the sole and the shin, but without purulent--necrotic signs. Confirmed data of clinic--instrumental investigations for chronic course of the ischemic process constitutes an absolute indication for operation.

ABSTRACT

The processes of change in the rate of generation of power response of artificially ischemic muscle using frequency modulated electrical efferent stimulation were investigated. A strain-gauge technique for registration of contraction process was used. Ischemia was induced by ligating main blood vessels of lower extremity. It is shown that ischemia causes a decrease in muscle performance and reduces maximum frequency of the stimulus signal, which leads to the titanic contraction level. It is shown that the lowering of ischemic muscle strength and reduction of the time that needed to establish a steady state depended on the time of discharge segment in stimulation pattern.

ABSTRACT

Correlation analysis between severity of the foot ischemic contracture (FIC) and the degree of its function disorder was conducted. The 100-point scale of H. B. Kitaoka was applied for investigation of functional disorders, the FIC severity was estimated according to A. P. Lyabakh, S. S. Strafun (1994) classification. The results obtained have witnessed the dependence of the foot functional state in a residual state from the ischemia severity, what is confirmed by Cruscal - Wallice and Dann criteria. Low indices in patients with a mild B and moderate A FIC severity were caused by impact of some factors, which were noncontrolled by the system of the point estimation, including such as the ischemic affection of own foot muscles.
