Decisive when making a decision on arthroplasty is a sharp limitation of movement in the joint and intense pain at the slightest movement, when conservative methods have already exhausted their possibilities. Conservative methods of treatment are able to preserve the function of the joint and stop the pathological process only at the initial stages.
Diseases that are an indication for hip replacement include:
- deforming arthrosis of the hip joints (coxarthrosis) 2-3 degrees
- ankylosing spondylitis with a primary lesion of the hip joints
- osteoarthritis of the hip joints in psoriasis
- aseptic necrosis of the femoral head
- ununited fractures and false joints after fracture of the femoral head
- recent fractures of the acetabulum and femoral neck in patients over 65 years of age
- rheumatoid arthritis with hip involvement
- tumors of the femoral head, femoral neck in patients of any age
The main goal of surgical treatment is to restore the shape of the acetabulum and the proximal segment of the femur, thereby bringing the pathologically altered structure of bone tissue as close as possible to anatomically correct and functionally stable.
Before performing the operation, the patient needs a thorough examination. In terms of preoperative examination, all patients undergo electrocardiography and laboratory examinations (blood and urine tests).
During a preliminary examination, and then when planning a surgical intervention, the issue of the size, model and method of fixing the endoprosthesis in the bones is decided. In each individual case, this issue is resolved strictly individually in order to achieve optimal results.
Choosing the right implant depends on many factors: the age of the patient, his lifestyle, the quality of bone tissue, the severity of the pathological process in the bone, existing bone deformities, etc. The service life of a high-quality endoprosthesis is 10-15 years. In 60 % cases, it reaches 20 years. In recent years, a new generation of artificial joints has appeared, the estimated life of which should reach 25-30 years. The service life of the endoprosthesis will largely depend on the load on the joint, on the quality of the bone tissue of this joint, as well as on the materials used in the endoprosthesis.
