[Experimental testing of an isolating-clutch endoprosthesis of the hip joint: the first results]

The paper presents the results of experimental tests of a new endoprosthesis. The study is devoted to the important issue the prevention on hip joint endoprosthetic instability occurring due to metallosis and its tissue responses. The prosthesis has the new design element an artificial capsule that protects tissue from metallosis. Experimental data were obtained by clinical observations of surgery-undergone dogs aged under a year and by X-ray, morphological and spectral studies. That the artificial capsule is highly effective in preventing the instability of the prosthesis and that the function of a limb is not limited by the capsule are shown.
