Septic arthritis is caused by an infection in the synovial fluid and joint tissues. It affects youngsters more frequently than adults. The infection normally spreads to the joints via the circulation. In certain situations, infection of the joints might occur as a result of an injection, surgery, or accident. Severe injuries to the joints may allow bacteria to enter the area directly. Organisms present in the blood may reach the joint through small breaks in the skin.
The most common form of septic arthritis is caused by Staphylococcus aureus. Other organisms that can cause arthritis include Salmonella, Escherichia coli (E. coli), Klebsiella, Enterobacter, Pseudomonas, Proteus, and Candida. Arthritis due to viral infections such as measles, mumps, rubella, and chickenpox has been reported but is very rare.
In children, septic arthritis most commonly results from hematogenous spread of bacteria from another site in the body. Frequent sources are the chest, abdomen, and pelvis. Risk factors for developing septic arthritis include previous joint disease/injury, chronic illness, malnutrition, drug abuse, and immune suppression (for example, following organ transplantation).
The onset of septic arthritis is rapid. Symptoms include pain, swelling, and redness of the joint followed soon after by fever and chills.
Septic arthritis is a severe joint infection caused by bacteria that migrate through your bloodstream from another region of your body. Septic arthritis can also arise when bacteria enter the joint by a penetrating injury, such as an animal bite or trauma. The bacteria proliferate inside the joint causing inflammation and destruction of cartilage and bone.
Antibiotic therapy should be started immediately after diagnosis to prevent further damage to the infected joint. In some cases, surgery may be necessary to remove all of the damaged tissue and place an antibiotic-laden implant into the site to kill any remaining bacteria.
If you are bitten by an animal, it is important to seek medical attention immediately. Failure to do so may lead to serious complications for you down the road.
Symptoms of septic arthritis may include
The most prevalent cause is bacterial infection with Staphylococcus aureus (staph). Staph bacteria may thrive on even healthy skin. When an infection, such as a skin infection or a urinary tract infection, travels via your bloodstream to a joint, septic arthritis can occur. The cartilage that covers some joints is very thin and easy to damage. If this tissue is injured during activity such as running or playing sports, it may not heal properly. As a result, small pieces of bone may protrude from the joint, causing arthritis later in life.
In children, mononucleosis (glandular fever) can also lead to arthritis. The virus infecting mononucleosis spreads through contact with saliva or blood. It usually goes away on its own without treatment, but if not there may be joint pain.
Joint pain may also be caused by problems with the lining of the joint itself. For example, the joint membrane may become inflamed due to injury or excessive use. This type of inflammation can lead to joint pain. In addition, cancer cells may spread into the joint space where they can cause pain. Cancer cells may enter the joint space through breaks in the skin or digestive system. They often grow in large groups and are called tumors. The term "metastasis" means "spread of disease" and refers to cancer spreading from one site to another.
When the synovium of a joint becomes inflamed, this is referred to as synovitis (or synovial inflammation). The synovium is a connective tissue that lines the interior of the joint capsule. It is also known as the stratum synoviale or synovial stratum. The term "synovitis" specifically refers to the lining of a joint.
The two main types of arthritis are osteoarthritis and rheumatoid arthritis. They are very different conditions that can be difficult to diagnose because they do not cause pain, swelling, or redness of the joint. Instead, they lead to loss of joint function over time.
Joints are where bones meet; therefore, they can become damaged if the surrounding tissues - such as cartilage or ligaments - become diseased or injured. This can happen due to age, genetics, obesity, or any other chronic condition. When this occurs, muscles, joints, and organs around the area may suffer from trauma caused by abnormal movement, instability, or degeneration of the bone structure.
Arthritis is the name given to inflammation of the joints. There are two main types of arthritis: osteoarthritis and rheumatoid arthritis.
Bacteria are the most common cause of infectious arthritis. Staphylococcus aureus (staph), a bacteria that dwells on healthy skin, is the most prevalent of them. A virus or fungus can also cause infectious arthritis. This occurs more often in people with suppressed immune systems resulting from cancer treatments or AIDS.
Infectious agents can reach the joints through two main routes: via the bloodstream or via small nerve endings called neurites. If you have blood circulation problems, an infection could reach your joints through your blood vessels. This is usually caused by bacteria that have seeped into the open wound at the site of a previous injury or surgery.
If you have joint pain and feel like it might be infected, see your doctor- sooner rather than later if possible! Your doctor will conduct a full examination of your joints to look for signs of inflammation (redness, heat, swelling) or infection (fever, chills, pain when moving or bending bones). They may do some tests to determine the cause of your arthritis. These include: X-rays, blood tests, and cultures of fluid collected from within the joint space.
The best defense against infectious agents is to avoid getting infections in the first place.
Rheumatoid arthritis Antibodies are produced by the immune system and adhere to the linings of joints. The joints are subsequently attacked by immune system cells, resulting in inflammation, swelling, and discomfort. Rheumatoid arthritis, if left untreated, causes slow, chronic joint deterioration. There is no cure for rheumatoid arthritis, but treatments can relieve symptoms and prevent further damage to the joints.
The most common symptom of rheumatoid arthritis is pain, especially in the hands, wrists, and feet. Pain may be felt all over the body, but it usually starts in one or more joints. The disease may cause other problems including fatigue, fever, sweating, red eyes, sore throat, chest pains, shortness of breath, cough, or problems sleeping.
There are several types of arthritis. They are generally classified based on three characteristics: type of fluid found in the joint, appearance of the joint lining, and the size of the joint space (the amount of room between bones). Rheumatoid arthritis is a progressive condition that can lead to permanent loss of mobility of the joints. It can affect any joint in the body but most often affects the joints of the hands, arms, legs, and feet. However, it has been known to occur in the neck, back, knees, and shoulders as well.
