Many types of surgery can be used to treat bone cancers. The type of surgery you have depends on where the tumor is and the stage (extent) of the tumor, your overall health, your personal choices, and other factors.
Surgery for tumors in an arm or leg
Limb-sparing or limb-salvage surgery is the most common surgery for a bone tumor in an arm or leg. The goal is to remove the tumor and some of the normal tissue around it, while still having the arm or leg look and work as normal as possible.
The part of bone with the tumor that's removed is replaced. It may be replaced with a bone graft, a metal rod (prosthesis), or a combination of a bone graft, metal rod, and other materials. A bone graft can be taken from another part of your body. Or it might be a donated bone from another person.
Limb amputation
In some cases, the surgeon may not think all of the tumor can be removed while saving the limb. Then surgery to remove the limb, called an amputation, might be needed. The surgeon will remove the limb and some normal tissue above the level of the tumor. You will then be fitted with an artificial limb, called a prosthesis (see below).
Rotationplasty
In special cases where the tumor is in the thigh bone or around the knee, you may need surgery called a rotationplasty. In this surgery, the tumor is removed. Then the lower part of the leg is rotated halfway around (180°) and attached to the upper part of the leg. This means that your ankle becomes your new knee joint. An external prosthesis is then used to replace the lower part of your leg. This surgery sounds strange, but it can allow you to walk. In very rare cases, a surgery like this is done for arm tumors. You will have a shorter arm, but still be able to keep your hand.
