3.  local control without sacrificing joint function.  intralesional curettage  With autograft reconstruction  With cementing  Sometime with adjuvant

4. With Autograft 1. reconstruction is permanent 1. Autograft quantity limited 2. Allograft expensive 3. Recurrence difficult to spot With Cementing 1. detection of recurrence is easier 2. Immediate structural support 1. Not a biological material 2. long-term degeneration

5.  may be of additional benefit in helping to decrease recurrence rates  methylmethacrylate  local hyperthermia  necrosis of any remaining neoplastic tissue

6.  for lesions of the spine and sacrum or for aggressive, multiply recurrent tumors  radiotherapy  no recognized effective chemotherapeutic agents available  surgery remains the treatment of choice
