Limb sparing surgery for bone cancer

Limb sparing surgery is the main operation for primary bone cancer in the arms or legs.

This page is about cancer that starts in your bone (primary bone cancer).

If your cancer has spread into bone from another part of the body, it is called secondary or metastatic bone cancer.

What is limb sparing surgery

Most primary bone cancers are in the arms or legs. Limb sparing surgery is the main operation for these cancers. This means removing the cancer without removing the affected arm or leg. It is also sometimes called limb salvage surgery.

The surgeon removes the area of bone containing the cancer and may replace it with a:metal implant called a prosthesis
replacement bone either from another part of the body or from a bone bank

In some cases the affected bone is taken out, treated with radiotherapy and then put back into the body.

Why you have limb sparing surgery

If your cancer is in an arm, leg, shoulder or hip, your surgeon will want to do limb sparing surgery if at all possible. This means removing the cancer, but not the whole arm or leg.

This is the most common type of surgery for primary bone cancer. Around 85 out of every 100 (85%) osteosarcomas are treated in this way.

It is often possible to remove just the tumour even if the cancer is in your hip bones (the pelvis). In the past, sometimes the whole leg and hip had to be removed.

What happens

You have the surgery in an operating theatre.Your nurse puts a small tube into a vein in the back of your hand. Your anaesthetist gives you the anaesthetic medicine through the tube and you go to sleep.

The surgeon removes the area of bone containing the cancer and replaces it with a metal implant called a prosthesis. If the cancer is near a joint, the surgeon will remove the joint as well and replace it with a false one.

You more commonly have this surgery to bones in the leg, such as the femur or tibia. These operations are called femoral replacement surgery and tibial replacement surgery respectively.

It is also done in the major bone in the upper arm, called the humerus. This operation is called humeral replacement surgery.

he most important thing is that the surgeon removes all the cancer. So they also take out a margin of healthy bone tissue all around the cancer. They send this to the laboratory to be carefully checked to make sure all the cancer has been removed.

Once the cancer is all out, the surgeon then performs the limb reconstruction part of the surgery.

Sometimes during the operation the tumour is found to be larger than the scans had shown or unexpectedly involves the nerves or blood vessels. When this happens, limb salvage may not be possible and an amputation has to be done instead.
