If the tumor is small and asymptomatic, surgery is not needed for the time being, while surgery is recommended for serious or multiple tumors. Wide-base osteochondroma is one of the common benign tumors in children. If the tumor is small and without any symptoms, surgery is usually not needed, and regular checkups can be conducted for observation. However, for patients with multiple or severe wide base osteochondroma, surgery is the only way to treat it completely to avoid recurrence. If wide base osteochondroma is left untreated, it may lead to joint atrophy and limb deformity in children, thus affecting normal life. Adults should be aware of the possibility of malignancy. If wide base osteochondroma is diagnosed, it is recommended to consult the doctor in time, complete the relevant examinations, and carry out regular treatment under the doctor’s guidance.
