Apibrėžimas

Osteoarthritis of the hip is an irreversible, progressive destruction of the klubų sąnarys. It usually occurs as a result of an incorrectly positioned acetabulum or a femoral vadovas that does not ideally fit the acetabulum.

Įvadas

Kaulinis klubų sąnarys is a large, central joint consisting of the joint vadovas (femur) and the acetabulum. It is involved in every change of position (sitting, standing, lying), which means that osteoarthritis of the hip can lead to considerable restrictions in the everyday life of the affected patients. 14% of the population show signs of hip osteoarthritis on X-rays, of which only 5% suffer from symptoms. Osteoarthritis of the hip is one of the rare forms of artritas. It occurs in 35% of cases on both sides.

Simptomai

The onset of the disease is usually insidious with little skausmas under stress. In the course of the disease there is radiating skausmas kirkšnyje, šlaunis, buttocks or even up to the knee. Typically, the initial skausmas is felt mainly in the morning after getting up and after sitting for a long time.

These symptoms improve during the day, but increase again in the evening. Patients also complain of rapid fatigue and a feeling of stiffness as further symptoms. In the case of advanced arthrotic changes in the hip, inflammation of the synovial membrane (sinovitas) occurs more frequently, which causes permanent pain independent of strain and masks typical symptoms such as starting pain.

Priežastys

A distinction must be made between primary and secondary artrozė. While the cause remains unknown in primary osteoarthritis, secondary osteoarthritis is preceded by another disease of the hip. A congenital cause of secondary osteoarthritis of the hip is for example klubo sąnario displazija, which has not been treated or has been treated unsuccessfully. Kraujotakos sutrikimai šlaunikaulio vadovas (šlaunikaulio galvos nekrozė, Pertheso liga) and solutions of the growth plate at the femoral head (epiphyseolysis capitis femoris) often lead to artrozė of the hip. Malpositions of the koja axis, inflammation or injuries of the klubų sąnarys are further specific causes of coxarthrosis.

Diagnozė

Due to the variety of symptoms, the diagnosis is made by means of physical examinations and X-rays. Inhibition of pagrobimas as well as internal rotation (i.e. turning inwards) of the femur in the hip can be signs of artrozė in the hip joint in addition to an extension deficit. Typical signs of arthrosis such as a narrowing of the joint space or bony attachments (so-called osteophytes) are to be expected in the Rentgeno image. If the klubo skausmas is unclear, arthrotic changes in the lumbar spine can also be the cause of the discomfort. By injecting a local anaesthetic into the joint space of the hip, it is possible in this case to determine where the pain comes from.
