what is a subchondral cyst
What about subcondral bone cyst? Subcondral bone cysts are liquid bags that form within a person's joints. Cysts occur in the subcondral bone, the bone layer just below the cartilage. The subcondral bone acts as a damper in the joints that support weight, such as knees, hips and shoulders. The fluid inside the subcondral bone (SBCs) is hyaluronic acid, a component found in synovial fluid, which is the thick substance that lubricates the joints, allowing the bones to slide between themselves without friction. Risk factors for SBCs include and smoke, but the exact cause is unknown. Symptoms include joint pain and discomfort. Lifestyle changes help relieve symptoms and can prevent the formation of other CBCs. Quick data on SBCs: Some experts believe that SBCs are a precursor of osteoarthritis (OA), which itself is a painful condition that affects more than adults in the United States. OA causes cartilage and bones within a joint to decompose gradually. SBCs are considered one of the four cardinal radiological findings or key to OA. However, in one of the 806 people with OA on the knee, the SBCs found in only 30.6 percent of them. Other conditions besides OA, such as, also cause cysts to form in the bone joints. Although the cause is unknown, it is believed that the SBCs are the result of repeated bone. This stress is caused by increased blood flow pressure faster to the subcondral bone, something seen in people with AO. Certain features and behaviors can increase the risk of developing a CBS. These include: It is recommended that SBCs be not treated directly. Because of the risk of infection, these cysts should not be eliminated. However, they can go back on their own. As a result, treatment usually involves making lifestyle changes and providing symptom relief. Some people may benefit from replacing the joint if the problems are continuous or progressive. Treatments for SBCs are as follows: Nonsteroidal anti-inflammatory drugs (NSAIDs)These free-selling analgesics, such as ibuprofen and , can reduce symptoms of SBCs. It is always advisable to consult with a doctor before taking . Long-term use should be avoided. Low-impact activities It is recommended to choose low-impact activities such as swimming, aerobic and cycling. These put less pressure on the knees and hip joints than high-impact activities, such as running and jumping, which can exacerbate OS and SBC symptoms and cause new joint damage over time. Weight Management Keeping a healthy weight reduces excess stress in the joints and can reduce the rate of cartilage loss. Quit Smoking As this is a risk factor for the development of osteoarthritis, and avoiding second-hand smoke can reduce symptoms of SBCs and OAs. Ultrasound Therapy At least one suggests that the delivery of ultrasonic therapy located to cartilage and subcondral bone can help treat the OA. However, much more research is needed in this area. Physiotherapy According to mild degenerative disease, of which SBCs can be a feature, it can be treated with . If you are present, the symptoms of SBCs may include: There are only some symptoms associated with SBCs, as they are usually considered an OA symptom, particularly progressive OA. SBCs are considered an OA symptom or other joint conditions. They can resolve for themselves or persist in the long term. SBCs can cause pain and contribute to disease progression. The best way to treat these cysts is to manage OA symptoms and other joint conditions. Last medical review on August 17, 2017Most recent newsRelated coverage
