ABSTRACT
Major indications for this operation are based on the anatomic site of the sarcoma, involving extensive lesions with neurovascular encasement, or bone invasion that prevents a lesser procedure. If the lesion is confined to the proximal thigh, hip disarticulation is occasionally an alternative. In the main, however, if a tumor is so proximally situated that hip disarticulation can be considered, hemipelvectomy would prove to be a more satisfactory operation.
