ELECTRET IMPLANT FOR TREATMENT OF ARTHROSIS

摘要

The invention relates to medicine, and more particularly, to electrotherapy using static electricity of electret coatings for treatment of arthrosis of different joints: knee, hip, and shoulder, including for the arthrosis treatment of small bones of arms and legs.;The invention allows increasing the therapeutic action efficiency of the electrostatic field of the electret coating of the implant on bone tissues by conservation of the initial charge density of the electret coating and its high stability over time.;The task in the present method for treatment of arthrosis is solved by the fact that an electret implant placing into a bone is made during a treatment course. The method is characterized by a preliminary performed hole in the bone directed towards a zone of a maximum lesion by pathological process. The electret implant is placed with a gap into the prepared hole in the bone so that it is as close as possible to the bone area affected by the pathological process. The implant is immobilized by a fixation device to prevent displacement of the implant with an optimum treatment position in the bone. The inventive electret implant includes an extended body with a proximal and a distal end. On surface of the body a dielectric coating in an electret state is formed. The implant, wherein its body is implemented as a rod, at the proximal end of which a frontal surface is formed, and the fixation device of the implant in the hole in the bone can be made at the distal end. The bushing, wherein on its outer surface a thread for its set is made in the hole in the bone, and on its inner surface a thread for fixation of the electret implant in the hole is made.

主权项

1. A method for treating arthrosis, comprising:
placing an electret implant into a bone, wherein a hole directed to an area of maximum destruction by pathological process is previously made in said bone, wherein said electret implant is placed with a gap into the prepared hole in said bone so that it is as close as possible to said area of maximum destruction by pathological process, wherein said implant is immobilized by a fixation device to prevent displacement of the implant with an optimum treatment position in the bone, wherein said electret implant is left in said bone of a patient until the time when pain syndrome appears which is connected with the fact that said electret has run down and has ceased to have stimulating effect on bone structures which leads to renewal of pathological processes which begin to grow again in said bone after the electret implant discharge and is accompanied by pain syndrome for said patient.
