Rheumatoid arthritis (RA) is not a selective disease. This indicates that RA can occur in any joint in the body, destroying it and causing pain and bringing disability to the patient. RA usually attack joints that are located in the upper groin region but is not limited to that only. In the initial stages, any form of strenuous activities such as jogging, running or even carrying a heavy object can aggravate the pain. As it slowly progresses, it will start to affect the quality of sleep and lead to patients being disorientated. Hip surgery is one of the most effective treatment methods of RA and we will look into it in this article.
Total hip replacement (THR) is the most common form of surgical treatment for RA with the other being hip resurfacing. In THR, there are three different components for the implant; the stem, ball and socket. The stem will fit itself into the femur while the ball will replace the spherical head of the femur and finally the cup will replace the worn out hip socket. The materials used for the implant have specifically been chosen for the biocompatibility properties. This means that they will not react with the body fluids and chemicals and ultimately causing an undesired immune response from the host body. The materials are also resistant to corrosion and are long-lasting in the region of a decade or more. The mechanical properties are as good as or even better than the natural components of the hip.
THR will be performed in a sterile operating theatre that is free of bacteria in order to prevent infection. Patients will be given a general anesthesia jab, which will cause them to fall asleep throughout the surgery. An incision will be made along the side of the hips and can be as long as 25cm. However, this incision will not be visible as the clothes will be able to cover it decently. The diseased joint will be removed with a surgical saw and the bone will be cleaned and prep for the arrival of the new prosthesis. There will be proper drainage systems to remove blood from the region and when everything is over, sutures will be used to close up the incision.
As with all forms of surgery, there are risks involved. There will always be a slight chance of the formation of a blood clot and infection despite sterilizing the operating theatre.
