Persistent growth of the mass: If the mass continues to grow after adulthood, showing obvious local pain, affecting normal activities of joints, compressing surrounding nerves or blood vessels, or even fracture or suspected malignant change, surgical excision should be performed for treatment. If treatment is not carried out in time, it may affect patients’ quality of life, malignant change may occur and shorten patients’ survival; 2. Multiple osteochondroma: If it is multiple osteochondroma, the possibility of malignant change is relatively high. It is suggested that patients should go to the orthopedic department of the hospital as early as possible for X-ray, CT and other examinations, and take corresponding treatment measures according to the examination results. If surgical treatment is performed, it may need to be done in several times. After surgery, patients need to undergo regular follow-up examinations to check the progress of the disease and any recurrence.
