Features of fixing the prosthesis during endoprosthetics


Prosthesis is a good way to improve the quality of everyday life in diseases of the musculoskeletal system, accompanied by deformation or destruction of large joints of the body. Osteoarthritis and arthritis of various types can lead to severe pain syndrome, limitation of mobility, violation of posture. With the proper selection of the endoprosthesis design and the method of its installation, the new joint can last about 20 years.

Endoprosthetics of the hip joint is performed by a cement and cementless method. They are equally effective, but the type of attachment is chosen individually, depending on the width of the bone channel, in which the leg of the prosthesis, the total density of hard tissues and other parameters will be fixed. When cementing an artificial joint is established using a special polymer composition, the so-called "bone cement".During the operation, it quickly solidifies( within 10 minutes), acquiring characteristics comparable to very dense rubber. This ensures a uniform redistribution of the load during walking, a slight cushioning for living tissues.

The cementless method of attachment is aimed at patients who clearly will not have problems with strengthening the bones after surgery. In operation, the rough prosthetic leg tightly enters the bone cavity. In a fairly short time, the body tissues are fused with the structure, holding it tightly.

It is necessary to determine the necessity of using bone cement in advance, since the choice of a specific model of the endoprosthesis depends on the attachment characteristics. If both the leg and the swivel cup are fixed by the composition, their surfaces are smooth, for the cementless method, products with rough surfaces are used. In addition, there are artificial joints designed for operations of mixed type - one end is cemented, the other - cementless.

The doctor's opinion plays the main role in choosing the final variant, although the final word always remains with the patient. Dr. Alexey Kalganov suggests that all patients with indications for prosthetics should conduct a comprehensive examination to find out the optimal way of installing the femoral endoprosthesis and direct the operation. High medical qualifications, vast experience, the availability of modern medical equipment - all this makes the specialist one of the best doctors in Russia in this field.
