Surgery for bone metastasis: fixing and protecting a weakened bone | CION Cancer Clinics
Surgery for a bone metastasis is usually done to strengthen a bone that cancer has weakened, before or after it breaks, or to take pressure off the spinal cord. Only occasionally is the aim to remove a single bone secondary completely. Radiotherapy usually follows. This page explains the operations, the warning signs that cannot wait, who surgery does not suit and what to ask. CION Cancer Clinics’ surgical oncologists in Hyderabad can talk this through with you.

The short answer
Why would someone need surgery for cancer in the bone?
Most surgery for cancer in the bone is done to hold a weakened bone together, so the person can stand, walk and sleep with less pain. The second common reason is to take pressure off the spinal cord. Removing a bone secondary completely is much less common.
What a bone metastasis is
A bone metastasis is a secondary tumour: cancer that started elsewhere and spread to the bone. Breast, prostate, lung, kidney and thyroid cancers are the usual sources. The cancer eats away at the bone, or makes it abnormally dense, and either way the bone loses strength.
Fixing a bone versus removing the cancer
Fixation means supporting the bone with a metal rod, plate, screws or a new joint. The cancer in the bone is usually left in place and treated afterwards with radiotherapy. Removing the whole secondary with a rim of healthy bone is sometimes considered for a single spot from kidney or thyroid cancer, when nothing else has spread. That is a bigger operation with a longer recovery.
Bone pain that is worse when you put weight on it, and does not settle with rest, is worth telling your oncologist about soon.

Signs that cannot wait
New back or neck pain with weakness, numbness or heaviness in the legs, or a new problem controlling urine or motions, can mean the spinal cord is being squeezed. Go to an emergency department the same day and say the person has cancer. Do not wait for the next clinic visit. Sudden severe pain in an arm or leg after a small movement may be a broken bone: keep the limb still and get help the same day.
Not sure whether this applies to you?
Ask an oncologistThe operations
Which operations are used for bone secondaries?
The choice follows which bone is affected and whether it has already broken.
A rod inside a long bone
A metal rod is passed down the hollow centre of the thigh or upper arm bone and fixed with screws. It supports the whole length of the bone, which matters if more spots appear further along.
Plate, screws and bone cement
Where a rod will not fit, a plate is screwed along the bone. The gap left by the cancer may be filled with bone cement, which sets hard at once.
A joint replacement
When cancer affects the end of a bone near the hip or shoulder, a metal joint is often more reliable than fixing it. Longer implants are used when more bone is lost.
Spinal surgery
The surgeon removes the bone or tumour pressing on the spinal cord and steadies the spine with screws and rods. Radiotherapy follows.
Cement injected into the spine
For a collapsed or painful vertebra, one of the bones of the spine, cement is injected through a needle to steady it, without an open wound.
Removing a single secondary
For one bone spot from kidney or thyroid cancer with nothing elsewhere, the whole spot may be removed and the bone rebuilt.
Ask your centre which of these operations they carry out.Being straight with you
Who is bone surgery not right for?
The team is answering two questions. Is this bone likely to break? And will an operation make daily life better for this person? Bone or spine surgeons, radiation oncologists and medical oncologists decide together.
Judging whether a bone will break
They look at how much of the bone's width the cancer has eaten away, whether the bone carries weight, what type of damage it is, and whether pain worsens on standing or walking. Scoring systems help, but they guide judgement rather than replace it.
When surgery usually does not help
An operation is less likely to be recommended if the person is very frail, cannot walk for other reasons, has cancer spreading quickly in many places, or would spend much of their remaining time recovering. For many bone secondaries, radiotherapy alone controls the pain well. Bone-strengthening medicines and good pain relief may do more for comfort than surgery.

The pathway
What happens before and after the operation?
-
Scans of the whole bone
X-rays, CT or MRI show how much bone is damaged and whether there are other spots nearby. For the spine, an MRI of the whole spine is usual.
-
Blood tests, including calcium
Cancer in bone can raise blood calcium, causing thirst, confusion and constipation. It is corrected before surgery.
-
Blocking the blood supply, sometimes
Spots from kidney or thyroid cancer can bleed heavily, so the vessels feeding them may be blocked through a thin tube before surgery.
-
The operation and getting up
Getting the person moving quickly is a main aim. Physiotherapists usually start very soon after surgery.
-
Radiotherapy and bone medicines
Radiotherapy to the area follows once the wound heals. Drugs such as zoledronic acid or denosumab may be given to protect bone. A dental check first is advised, and your oncologist sets the timing.
On your report
What do the words on the report mean?
- Pathological fracture
- A break in a bone weakened by disease, often after a small movement rather than a fall.
- Impending fracture
- A bone that has not broken but is weak enough that it is likely to.
- Lytic lesion
- An area where cancer has dissolved bone. Sclerotic means the bone has become abnormally dense.
- Spinal cord compression
- The spinal cord is being squeezed by collapsed bone or tumour. It needs urgent treatment.
- Hypercalcaemia
- Too much calcium in the blood.
Commonly believed
What do families often believe about bone secondaries?
"Cancer in the bone means he will never walk again."
Many people with bone secondaries keep walking for a long time. Radiotherapy, medicines and, when needed, surgery aim to keep them mobile. Acting early on warning signs, especially in the spine, matters most.
"Once the rod is in, the cancer in that bone has gone."
The rod supports the bone. It does not remove the cancer, which is why radiotherapy usually follows. Metal can loosen if the cancer keeps growing, so follow-up X-rays matter.
"Back pain at this age is just old age."
It may be. But new back pain in someone with cancer, especially pain worse at night or lying flat, should be reported. Spinal spread caught before weakness begins is much easier to treat.
"Complete bed rest protects a weak bone."
Long bed rest brings blood clots, chest infections, pressure sores and muscle loss. The team will say which movements are safe until the bone is protected.
Questions we are asked
Common questions about bone metastasis surgery
Why operate if the bone has not broken yet?
Fixing a bone before it breaks is usually a simpler operation with a quicker recovery than repairing a break. It also avoids the pain of a sudden fracture. The team suggests it when scans and symptoms show a high chance of breaking. Ask what they saw that makes them think so.
Will the metal rod ever need to come out?
Usually not. The rod or plate is meant to stay for life. Occasionally metalwork loosens if the cancer keeps growing around it, and more surgery may be discussed. Tell the team about any new pain in that limb rather than waiting for the next review.
When can my father walk after hip fixation?
Many people stand with a frame very soon after surgery, because staying in bed carries its own risks. How much weight the leg may take depends on the fixation and the bone quality. The surgeon decides what is allowed, and physiotherapists guide each step.
What are the risks of this surgery?
Bleeding, infection, blood clots, slow wound healing after radiotherapy and loosening of the metalwork are the ones surgeons discuss most. Spinal surgery also carries a risk of nerve damage. Ask how often these happen in their unit and what would be done.
Is radiotherapy still needed after the operation?
In most cases, yes. Surgery holds the bone together but leaves cancer cells around it. Radiotherapy helps control those cells, eases pain and protects the metalwork. It usually starts once the wound has healed. The radiation oncologist will explain the plan.
Should his tablets be stopped before surgery?
Pain relief usually continues right up to surgery. Some medicines, such as blood thinners and diabetes tablets, may need changes around the operation. Bring every medicine to the pre-surgery visit and let the surgeon, anaesthetist and prescribing doctor decide. Do not stop or change anything on your own.
Will the pain go away after fixation?
Pain from a broken or unstable bone usually eases a lot once the bone is fixed, because it no longer moves. Wound pain settles over the following weeks. Pain from cancer in other bones may remain, so tell the team what still hurts.
Is this surgery covered by Aarogyasri or insurance?
Cancer surgery is often covered under Aarogyasri, CGHS, ECHS, EHS and many cashless insurance policies, subject to approvals and package limits. Call the helpline with your card or policy details and your own cover can be checked.
