If there are obvious symptoms or affect the normal function of limbs, surgical resection can be chosen. Giant cell tumor of bone generally take tumor scraping and bone grafting + inactivation treatment, if the tumor recurs, then the tumor segment bone amputation + prosthesis reconstruction should be carried out.
