When the cartilage structure is disrupted or damaged, the smooth, slippery mobility in the joint is also impaired. Cartilage wears off and friction between surfaces gradually increases. As a result, the wear area in the cartilage expands and deepens. Over time, the cartilage tissue covering the bones that make up the hip joint disappears, and the bone begins to rub against the bone. The shape of the femoral head, which is like a smooth ball, also deteriorates, and it begins to rotate freely in the socket. Thus, while the inward and outward rotational movements of the leg are restricted, it becomes difficult to perform other movements over time.
When calcification occurs in the hip joint due to the wear of the cartilage covering the surface of the bones that make up the hip joint, pain and limitation in movement develop in the hip.
People with hip joint calcification have difficulty in performing movements such as walking, sitting and standing on a chair, and squatting. In patients who previously walked with a slight limp, significant limping begins with the weakening of the muscles around the hips.
In cases where hip joint calcification is suspected, hip movements are evaluated in the examination. In addition, movements such as walking style, sitting and standing, squatting are evaluated. In order to detect the problem in the hip joint, first x-rays are taken and blood tests are done if necessary. In addition to these, tests such as hip joint ultrasonography, computerized tomography, magnetic resonance imaging may be requested depending on the situation. In order to distinguish the pain radiating from the waist to the hip, if necessary, additional examinations may be required by evaluating the lower back area.
With hip replacement surgery, it relieves pain and limitation of movement in people with hip joint calcification and gives mobility to the hip joint.
There are three different types of hip replacement;
