Osteomyelitis effusion requires the following management measures: i. Such patients require complete braking, such as continuous bed rest. With the help of family members, the patient should visit the orthopedic department of the nearest hospital to thoroughly investigate the cause of the current symptoms, which may be acute or chronic osteomyelitis induced by osteochondritis. Second, if it is clear after consultation that it is a localized osteochondritis, a period of intensive anti-inflammatory treatment can be done. For example, the patient should take oral non-steroidal drugs to reduce inflammation and pain, such as nimesulide, ibuprofen, and diclofenac sodium, on a continuous bed rest basis. In addition to this, the patient can also fumigate the painful area externally with herbs. Third, if the presence of septic osteomyelitis is confirmed after consultation, timely anti-infective treatment is required. For example, early application of an adequate amount of sensitive antibiotics, and then depending on the patient’s response to treatment, elective surgical treatment. There are many surgical options for this type of disease, the principle of which is to completely remove the necrotic bone, drain the internal pus thoroughly, and then assist other conservative treatments to do follow-up treatment.
