Half a year after recovery from fracture, there is still effusion according to the different parts of the fracture, the treatment method is different, common fracture parts are rib fracture, patella fracture and pelvic fracture. Commonly used treatment methods include general treatment, physical therapy, drug treatment and surgery. 1. Rib fracture: rib fracture can cause pleural effusion, and the amount of effusion should be clarified first. If the amount of fluid is small and not accompanied by dyspnea, conservative treatment such as rest, braking, hot compresses, use of non-steroidal anti-inflammatory drugs such as ibuprofen, etc. can be used or left untreated to wait for the fluid to be absorbed by itself. If the amount of effusion is large, thoracentesis can be used to extract the effusion or closed drainage of the thoracic cavity. 2. Patella fracture: in addition to the above methods, drugs such as sodium vitrate and glucocorticoids can be injected into the joint cavity. Antibiotics such as penicillin, ceftriaxone sodium can be used when accompanied by infection, or intra-articular cavity irrigation. 3. Pelvic fracture: When the amount of fluid is small, no special treatment is needed and the fluid can be absorbed by itself. By resting, avoiding spicy food such as chili peppers, and prohibiting smoking and alcohol. Phototherapy and intermediate frequency therapy can improve blood circulation and promote recovery. Antibiotics can be used when accompanied by infection. If the effusion is serious, surgical treatment such as puncture and drainage can be done.
