Bone Cancer Surgery

Introduction

A diagnosis of bone cancer raises difficult questions about survival, mobility, independence, and what daily life will look like afterwards. For most patients, surgery is the central step in the treatment plan. It is not a single operation done in isolation — it is a carefully planned cancer operation done by a specialist team, usually combined with chemotherapy and sometimes radiation, depending on the tumour type.

Over the past three to four decades, outcomes have changed substantially. Limb-salvage surgery — removing the tumour while keeping the arm or leg — is now possible for the large majority of patients who would once have needed an amputation. Reconstruction with custom metal implants, donor bone, or combinations of both has become routine in specialist centres. At the same time, surgery for bone cancer remains complex, and the planning that happens before the operation is as important as the operation itself.

This guide explains what bone cancer surgery involves: how candidates are selected, what the different surgical approaches are, how the operation is planned and performed, what recovery and rehabilitation look like, and what follow-up is needed in the years afterwards. It is written for patients who already have a diagnosis or are being investigated for a bone tumour and are now thinking about the surgical step ahead.

What Is Bone Cancer Surgery?

Bone cancer surgery is the surgical removal of a cancerous tumour from a bone. The goal is to remove the entire tumour along with a rim of normal-looking tissue around it — called a “clear margin” or “negative margin” — so that no visible cancer cells are left behind at the edges. Removing the tumour as a single intact block, without cutting into it, is referred to as en bloc resection and is the standard approach for bone sarcomas.

The operation has two parts that the surgeon plans together:

• Resection — removing the tumour and the surrounding margin of healthy tissue.
• Reconstruction — rebuilding the gap left behind so that the limb or body part can function again. This may involve metal implants, transplanted bone, joint replacements, or combinations of these.

Two broad situations are treated under the umbrella of “bone cancer surgery”:

• Primary bone cancer (bone sarcomas) — cancers that start in the bone itself. The main types are osteosarcoma, Ewing sarcoma, and chondrosarcoma. Surgery is a central, curative-intent step in their treatment.
• Metastatic bone disease — cancer that has spread to bone from another organ, such as breast, lung, prostate, kidney, or thyroid. Surgery here is usually done to stabilise a bone that is broken or about to break, to relieve pain, or to maintain function, rather than to cure the underlying cancer.

The principles, planning, and outcomes of these two situations are different, and an experienced orthopaedic oncology team will plan each accordingly.

Why Bone Cancer Surgery Is Performed

The reasons for operating depend on the type of tumour and the overall treatment plan agreed by the multidisciplinary tumour board — the group of specialists (medical oncologist, orthopaedic oncologist, radiation oncologist, pathologist, radiologist, and others) who review the case together.

Common indications include:

• Cure of a localised bone sarcoma. For osteosarcoma, Ewing sarcoma, and chondrosarcoma confined to one bone (with or without limited spread), surgery combined with chemotherapy is the established treatment path.
• Removal of an aggressive benign tumour. Some tumours are technically not cancer but behave aggressively (for example, giant cell tumour of bone). Surgery is often part of their management.
• Stabilising or replacing a bone affected by metastatic cancer. When a bone in the leg, arm, hip, or spine is weakened or broken by a tumour deposit, surgery can fix or replace the affected segment to restore weight-bearing and reduce pain.
• Relieving pressure on the spinal cord or nerves. Tumours in or near the spine that compress nerves may need surgical decompression.
• Controlling local disease when other treatments are not enough. Chondrosarcoma, for example, does not respond well to chemotherapy or radiation, so surgery is the main treatment.

Who Is a Candidate?

Whether surgery is appropriate — and which type of surgery — is a clinical decision made by the tumour board after detailed staging. Several factors are weighed together:

• Tumour type. Different bone cancers behave differently and respond differently to chemotherapy and radiation.
• Location. A tumour in the middle of a long bone is usually easier to remove with limb preservation than one wrapped around major nerves and blood vessels, or one in the pelvis or spine.
• Size and extent. How far the tumour has spread within the bone and into surrounding soft tissue.
• Distant spread (metastasis). Whether the cancer has spread to the lungs or other sites. Surgery may still be done, but the overall plan changes.
• Response to chemotherapy. For osteosarcoma and Ewing sarcoma, chemotherapy is usually given before surgery (neoadjuvant chemotherapy). A good response makes surgery safer and may make limb preservation possible.
• General health. Heart, lung, and kidney function; nutrition; other medical conditions; and age all affect the safety of major surgery and anaesthesia.
• Skeletal maturity (in children). In growing children, the surgeon must plan for future bone growth.

Patients are usually managed in centres that handle bone sarcomas regularly. International guidelines from the National Comprehensive Cancer Network (NCCN) and the European Society for Medical Oncology (ESMO) emphasise that bone sarcomas should be treated in specialist sarcoma centres with multidisciplinary teams, because both outcomes and the chance of limb preservation are better when surgical volume and experience are high.

Alternatives and Adjuncts to Surgery

Surgery is rarely the only treatment for a bone sarcoma. It almost always sits within a wider plan. Understanding the other parts of that plan helps explain why the surgery is timed when it is.

Chemotherapy

For osteosarcoma and Ewing sarcoma, chemotherapy is typically given both before and after surgery. The pre-surgery (neoadjuvant) phase is used to shrink the tumour, kill any microscopic spread, and give the team information about how the cancer is responding. After surgery, the pathologist examines the removed tumour to estimate how much was killed by the chemotherapy — this guides the chemotherapy plan after surgery.

Chondrosarcoma, by contrast, generally does not respond to standard chemotherapy, so the plan is more surgery-centred.

Radiation therapy

Radiation plays a major role in Ewing sarcoma, particularly when the tumour is in a location that is difficult to operate on (for example, parts of the pelvis or spine) or when surgical margins are close. It is used less often in osteosarcoma because osteosarcoma is relatively resistant to radiation, although it may be considered in selected cases. Chondrosarcoma is also relatively radiation-resistant, but proton or photon radiation may be used for tumours in sites where complete surgical removal is not possible.

Targeted therapy and immunotherapy

For some bone sarcomas and for many metastatic cancers that spread to bone, targeted drugs or immunotherapy may be part of the wider plan. These do not usually replace surgery for primary bone sarcomas but may be combined with it.

Watchful waiting and biopsy alone

For some low-grade or borderline lesions, the team may decide that close monitoring with imaging is safer than immediate surgery. The decision is individualised.

Non-surgical control of metastatic bone disease

When cancer has spread to bone from another organ, radiation, bone-strengthening medicines (such as bisphosphonates or denosumab), pain management, and systemic cancer treatment may control symptoms without surgery. Surgery is added when a bone is at risk of breaking or has already broken, or when nerves are being compressed.

Pre-Surgical Evaluation and Planning

Detailed staging is done before surgery so that the team understands exactly what they are dealing with. This is one of the most important parts of bone cancer treatment, because the quality of the planning shapes the result.

Tests commonly used include:

• MRI of the affected area. This is the most important scan for understanding how far the tumour has spread within the bone and into surrounding soft tissue, nerves, and blood vessels. It guides the surgical plan in detail.
• CT scan of the chest. Bone sarcomas spread most often to the lungs, so a chest CT is standard.
• Bone scan or PET-CT. To check for spread to other bones or other parts of the body.
• Biopsy. A small sample of the tumour is taken for the pathologist to examine. The biopsy is critically important and is best done at the centre that will perform the definitive surgery, because a poorly placed biopsy can compromise later limb-salvage options.
• Blood tests. Routine blood counts, kidney and liver function, and markers such as alkaline phosphatase or lactate dehydrogenase, which may give additional information for some sarcomas.
• Heart, lung, and anaesthesia assessment. Especially relevant for patients who will receive chemotherapy with cardiac side effects.
• Dental and nutritional review. Often done before chemotherapy.

If chemotherapy is part of the plan, repeat imaging is done after the pre-surgery chemotherapy to reassess the tumour and finalise the surgical approach. In children and young adults of reproductive age, fertility preservation is discussed before chemotherapy starts.

Surgical Approaches

The surgeon chooses between a limb-salvage approach, an amputation, or specialised resection (for tumours in the pelvis, spine, or other complex sites) based on tumour location, size, response to chemotherapy, involvement of major nerves and vessels, and the patient’s overall situation. The principles below describe what each approach involves.

Limb-Salvage Surgery

Limb-salvage surgery (also called limb-sparing surgery) removes the tumour and a margin of healthy tissue while keeping the arm or leg intact and functional. In large international series and specialist sarcoma centres, the majority of patients with extremity bone sarcomas are now treated with limb-salvage surgery. The exact proportion depends on tumour size, location, and response to chemotherapy.

The defect left after the tumour is removed is reconstructed in one of several ways:

• Endoprosthesis — a custom-designed metal implant that replaces the removed segment of bone and the adjacent joint (for example, a distal femur prosthesis when the lower end of the thigh bone is removed). Endoprosthetic reconstruction is the most common method for tumours around the knee, hip, and shoulder.
• Allograft — bone from a donor (cadaveric) that is shaped to fit the gap. The patient’s own bone gradually grows into and integrates with the allograft over time.
• Autograft — bone taken from another part of the patient’s own body (such as the fibula in the lower leg) used to fill the defect. Vascularised fibula grafts — where the bone is moved with its blood supply intact — are often used.
• Allograft-prosthesis composite — a combination of donor bone and a metal implant.
• Rotationplasty — a specialised reconstruction used mainly in children with tumours around the knee. The lower leg is rotated and reattached so that the ankle joint functions as a knee joint when fitted with a prosthesis. It looks unusual but can give excellent long-term function and durability.

Limb-salvage surgery is technically demanding and the operation is usually long, often four to eight hours or more. Patients should understand that limb-salvage does not always mean a normal-functioning limb; the goal is a functional, durable, and pain-free limb, which is generally better than an amputation but not the same as the original limb.

Amputation

Amputation removes the affected part of the limb. It is recommended less often today than in the past but remains the right choice in specific situations, including:

• Tumours that involve major nerves and blood vessels in a way that cannot be safely separated.
• Very large tumours where adequate clear margins cannot be achieved with limb preservation.
• Tumours complicated by serious infection or by a pathological fracture that has contaminated surrounding tissue.
• Recurrence after a previous limb-salvage operation, when re-resection is not feasible.
• Situations where limb-salvage reconstruction would result in a poorly functioning, painful limb that is worse than an amputation with a modern prosthesis.

Amputation level (above-knee, below-knee, hip disarticulation, hemipelvectomy, above-elbow, below-elbow, and so on) depends on tumour location. Modern prosthetic limbs — especially for below-knee and above-knee amputations — can allow patients to return to walking, working, and many sporting activities. For some patients and some tumour locations, amputation gives a more reliable functional result with fewer long-term complications than complex limb-salvage.

Pelvic, Spinal, and Other Complex Resections

Tumours in the pelvis, spine, sacrum, scapula, and skull base are among the most challenging in bone oncology. These operations are planned in detail by surgeons with specific expertise in axial-skeleton sarcomas, often with help from vascular surgeons, plastic surgeons, urologists, or general surgeons.

Reconstruction in these sites may involve custom 3D-printed implants, allografts, large soft-tissue flaps to cover the defect, or pelvic prostheses. In some pelvic tumours, internal hemipelvectomy (removing part of the pelvic bone while preserving the leg) is possible. In selected spinal tumours, en bloc spondylectomy (removing one or more vertebrae as a single block) may be done.

These operations carry higher risks than extremity surgery and require longer recovery, but in specialist hands they offer real chances of local cure for tumours that were once considered inoperable.

Surgery for Metastatic Bone Disease

When cancer has spread to bone from another organ, surgery is usually aimed at restoring function and relieving pain rather than at cure. Common procedures include:

• Internal fixation with rods, plates, or screws to stabilise a bone that has broken or is at risk of breaking.
• Joint replacement when a tumour involves a joint such as the hip or shoulder.
• Spinal decompression and stabilisation for tumours pressing on the spinal cord.
• Less invasive procedures such as cementoplasty — injecting bone cement to strengthen a weakened bone — in selected cases.

The choice between these depends on life expectancy, the type of underlying cancer, and overall goals of care.

Preparing for Bone Cancer Surgery

The weeks leading up to surgery are usually busy. Common steps include:

• Completing pre-surgery chemotherapy (if planned) and allowing time for blood counts to recover before the operation.
• Pre-anaesthesia assessment by the anaesthesia team, including review of heart, lung, and kidney function.
• Nutritional optimisation. Good nutrition supports wound healing and resistance to infection. A dietitian may be involved.
• Smoking cessation. Stopping smoking, even a few weeks before surgery, reduces the risks of poor wound healing, chest infections, and clots.
• Dental review. Untreated dental infection can be a source of bacteria that infect an implant.
• Physiotherapy consultation. Meeting the physiotherapist before surgery helps with planning rehabilitation, learning how to use crutches or a walker, and starting strength work in the unaffected limbs.
• Blood tests, blood typing, and arrangements for transfusion if needed. Major bone surgery can involve significant blood loss.
• Discussion of reconstruction options and what the limb is expected to do afterwards. For amputation, this includes early discussion with a prosthetist.
• Fertility preservation discussions when chemotherapy is involved.
• Psychological support. A bone cancer diagnosis and major surgery affect mood and family life; counselling is part of care in most sarcoma centres.

Patients are usually asked not to eat for several hours before the operation, to shower with an antiseptic wash the night before and the morning of surgery, and to bring loose, comfortable clothing suitable for the early days of recovery.

What Happens During Bone Cancer Surgery

Bone cancer surgery is done under general anaesthesia — the patient is fully asleep. For lower-limb operations, an additional regional anaesthetic block (such as a nerve block) may be used to control pain in the early days afterwards.

The general sequence is:

1. Positioning and preparation. The patient is positioned on the operating table to give the surgeon the best access. The skin is cleaned with antiseptic and sterile drapes are placed.
2. Incision and exposure. The surgeon makes an incision carefully planned to allow removal of the tumour as a single block while protecting important nerves, blood vessels, and muscles. The previous biopsy scar is usually included within the planned excision.
3. Resection. The tumour and surrounding margin of healthy tissue are removed en bloc. The specimen is sent to the pathologist, who later confirms whether the margins are clear.
4. Reconstruction. The defect is reconstructed using the planned approach — endoprosthesis, allograft, autograft, or a combination. In amputations, the residual limb (stump) is shaped to suit a future prosthesis.
5. Soft-tissue closure. Muscles and skin are closed in layers. Plastic surgery techniques, such as muscle flaps or skin grafts, may be used to cover the reconstruction when the defect is large.
6. Drains. Small tubes are usually left in place to drain fluid from the wound for the first few days.

Duration depends on complexity. A straightforward extremity limb-salvage may take three to five hours; pelvic or spinal resections may take eight hours or longer.

Recovery and Healing

Recovery from bone cancer surgery happens in stages and overlaps with the rest of the cancer treatment plan.

The hospital stay

Most patients spend several days in hospital after extremity surgery, and longer after pelvic or spinal surgery. The first day or two may be in a high-dependency or intensive care unit if the operation was long or involved significant blood loss. Pain is managed with a combination of medicines, often including a nerve block or patient-controlled pain pump in the early days.

Early mobilisation — sitting up, moving to a chair, and starting basic exercises — usually begins within the first 24 to 48 hours when safe. Physiotherapy is started early.

Wound healing and the first weeks

Drains are removed when output is low. Sutures or staples are usually removed at around two weeks. Wound care, watching for signs of infection (increasing redness, swelling, drainage, fever), and avoiding pressure on the incision are emphasised in the early weeks.

Adjuvant chemotherapy — if planned — usually restarts a few weeks after surgery once the wound is healing well.

Rehabilitation

Rehabilitation is one of the most important parts of recovery. For limb-salvage patients, physiotherapy focuses on:

• Protecting the reconstruction (often partial weight-bearing for several weeks before full weight-bearing).
• Restoring the range of motion of nearby joints.
• Rebuilding muscle strength.
• Walking retraining and balance work.

For amputees, rehabilitation focuses on stump care and shaping, fitting and learning to use a prosthesis, walking retraining, and adapting to daily life. Prosthetic fitting usually begins a few weeks after the operation, once the stump has healed enough.

General timeline

Every patient is different, but common milestones after extremity limb-salvage surgery include early wound healing in the first two to three weeks, gradual increase in weight-bearing and mobility over the first two to three months, and substantial functional improvement by six months. Many patients continue to gain strength and function for a year or more after surgery. Pelvic and spinal surgery recoveries are typically longer.

Returning to work, school, or sport depends on the operation, the kind of work or activity, and the rest of the cancer treatment. Light desk-based work may be possible within weeks; physically demanding work or contact sport may take many months or may need to be modified long-term.

Risks and Complications

Bone cancer surgery is major surgery and carries real risks. The risks vary widely depending on the type of operation, the location of the tumour, the patient’s general health, and whether chemotherapy or radiation has been used. Risks discussed by surgical teams typically include:

• Bleeding during or after surgery, sometimes requiring transfusion.
• Infection of the wound or of the implant. Infection rates are higher for bone cancer surgery than for routine orthopaedic surgery because chemotherapy weakens immunity and the operations are long.
• Blood clots in the legs (deep vein thrombosis) or lungs (pulmonary embolism). Blood-thinning injections and early mobilisation are used to reduce this risk.
• Nerve injury, which may cause weakness or numbness in part of the limb.
• Wound healing problems, especially in areas treated with radiation or after long operations.
• Implant complications — loosening, breakage, dislocation, or wear of an endoprosthesis over the years. Endoprostheses are not designed to last forever, and revision surgery may be needed in the future, particularly for younger patients.
• Allograft complications — non-union (the graft not fusing with the patient’s own bone), graft fracture, or resorption.
• Stiffness, limb-length difference, or reduced strength in the operated limb.
• Phantom limb sensation or pain after amputation.
• Local recurrence — the cancer coming back in the same area — which is one of the reasons margins, response to chemotherapy, and follow-up are taken so seriously.
• Anaesthesia-related risks, particularly in patients with heart or lung disease.

Treatment at centres with high surgical volume and dedicated multidisciplinary sarcoma teams is associated with lower complication rates and better long-term outcomes for bone sarcomas, which is one reason international guidelines emphasise specialist care.

Life After Bone Cancer Surgery

Life after bone cancer surgery is shaped by the type of surgery, the rehabilitation that follows, and the wider cancer treatment plan. For many patients, the goal is not only to be cancer-free but also to return to a life that feels their own — work, school, family roles, hobbies, and physical activity.

Mobility and activity

After limb-salvage surgery around the knee or hip, most patients can walk well, often with a slight limp, and many can return to recreational activity such as swimming, cycling, golf, or hiking. Running and contact sports may be restricted to protect the reconstruction, but the surgical team gives individualised guidance.

Future surgery

Patients with endoprostheses may need revision surgery at some point in their lives. In children, expandable prostheses or planned future operations are part of the long-term plan.

Bone health

Calcium, vitamin D, and general bone-protective measures are often recommended, particularly for patients who have received chemotherapy or who have reduced activity in one limb.

Emotional and social adjustment

Bone cancer treatment is demanding and can affect mood, body image, relationships, school or work performance, and family life. Psychological support, peer-support groups, and counselling are an important part of care, and benefit many patients and families.

Follow-up and surveillance

After treatment, structured follow-up is critical. The aim is to detect any recurrence or spread early and to monitor the reconstruction. A typical follow-up pattern, used in many sarcoma centres and supported by international guidelines, involves:

• Visits every two to three months for the first two years.
• Visits every four to six months in years three to five.
• Annual visits thereafter, often continuing for at least ten years.

Each visit usually includes a clinical examination, imaging of the surgical site (X-ray and sometimes MRI), and chest imaging (chest X-ray or CT) to check for lung spread. The exact schedule and tests are tailored to the type of tumour and the individual situation.

Bone Cancer Surgery in Children and Young People

Two of the main bone sarcomas — osteosarcoma and Ewing sarcoma — have their peak incidence in teenagers and young adults. Bone cancer surgery in children and young people has several distinct considerations.

Growing skeleton

Removing part of a long bone that contains a growth plate can lead to a difference in limb length as the child grows. Surgeons plan for this using techniques such as:

• Expandable endoprostheses that can be lengthened as the child grows, sometimes non-invasively using an external magnetic mechanism.
• Rotationplasty, particularly for tumours around the knee, which gives a durable, growth-friendly result.
• Biological reconstructions using the patient’s own bone (such as a vascularised fibula graft) that can continue to grow.

Chemotherapy intensity

Chemotherapy for osteosarcoma and Ewing sarcoma in young patients is intensive and given over many months. Surgery is one milestone in a long treatment plan. The whole journey usually involves close coordination between paediatric oncologists, orthopaedic oncologists, nurses, physiotherapists, schoolteachers, and the family.

Fertility

Chemotherapy can affect future fertility. Fertility preservation options — such as sperm banking for boys, and egg or ovarian tissue preservation for girls — are discussed before chemotherapy starts wherever possible.

School and social life

Treatment disrupts school attendance and social life. Many sarcoma centres include education liaison and social work support. Returning to school, sport, and friendships is part of the recovery and is planned actively with the team.

Long-term follow-up

Childhood cancer survivors need long-term follow-up not only for cancer recurrence but also for late effects of chemotherapy (heart, hearing, kidney, fertility, second cancers) and for the durability of the reconstruction as they grow into adulthood.

Frequently Asked Questions

Will I lose my limb?

For most patients with bone sarcoma of an arm or leg, limb-salvage surgery is possible. The decision depends on tumour location, involvement of nerves and blood vessels, response to chemotherapy, and individual factors. Where amputation is the safer or more functional choice, modern prosthetic limbs allow many patients to return to active lives.

How long will I be in hospital?

Most patients stay several days to about two weeks after extremity surgery, and longer after pelvic or spinal operations. The exact length depends on the operation, recovery from anaesthesia, pain control, wound healing, and how quickly rehabilitation progresses.

Will I need chemotherapy as well?

For osteosarcoma and Ewing sarcoma, chemotherapy is usually part of the plan, both before and after surgery. Chondrosarcoma generally does not respond to chemotherapy and is treated mainly with surgery. For metastatic bone disease, the underlying cancer is treated with the appropriate systemic therapy.

Will the cancer come back?

Recurrence is possible, which is why structured follow-up is so important. The risk depends on tumour type, stage, surgical margins, and response to chemotherapy. Your treating team can give an individualised estimate based on your specific situation. Detecting recurrence early matters because further treatment is often possible.

How long does the recovery take?

Wound healing takes a few weeks. Walking, strength, and function continue to improve over months. Many patients reach a level of function they can live well with by six to twelve months after surgery, though gains can continue beyond that.

Will I be able to walk normally again?

Many patients walk well after limb-salvage surgery, sometimes with a small limp. After lower-limb amputation, walking with a prosthesis is the goal for most patients and is achievable for the majority with rehabilitation. Running and high-impact sport may be limited depending on the surgery and reconstruction.

How long does an endoprosthesis last?

Endoprostheses are durable but not permanent. Many last well over a decade, but revision surgery to replace worn or loosened components is sometimes needed, particularly for younger patients with longer life expectancy. This is part of the long-term planning.

Can I have children after treatment?

Chemotherapy can affect fertility, so fertility preservation should be discussed before chemotherapy starts where possible. Many people go on to have children after bone cancer treatment, but planning ahead is important.

What should I look for in a centre that treats bone cancer?

International guidelines recommend that bone sarcomas be treated in centres with a multidisciplinary sarcoma team, regular experience with these tumours, dedicated orthopaedic oncology surgical expertise, and access to advanced imaging, radiation, and reconstructive options. Asking about the team’s case volume and how they coordinate between specialists is reasonable.

Conclusion

Bone cancer surgery is a major step in a longer treatment plan that usually also involves chemotherapy and sometimes radiation. Decades of progress in orthopaedic oncology mean that limb preservation, durable reconstruction, and meaningful recovery of function are realistic goals for most patients with bone sarcomas of the arms and legs, and that even tumours in complex sites such as the pelvis and spine can often be removed in specialist centres.

The result of treatment depends on the type and stage of the tumour, the quality of staging and surgical planning, the expertise of the multidisciplinary team, the response to any chemotherapy, and a disciplined approach to rehabilitation and long-term follow-up. Whatever the specific path, understanding what to expect — the staging, the choices, the operation itself, the months of recovery, and the years of follow-up — helps patients and families take part in decisions and plan the next phase of life with clearer expectations.
