Limb-salvage surgery removes a bone tumour together with a surrounding cuff of healthy tissue and rebuilds the gap, most often with a modular metal implant called an endoprosthesis or megaprosthesis that replaces the missing bone and the adjacent joint. It is used for primary bone cancers such as osteosarcoma, Ewing sarcoma and chondrosarcoma, and for some destructive metastases.
It lets around 85 to 90 percent of patients with limb sarcomas avoid amputation without reducing the chance of cure. The reconstructed limb is not normal: high-impact sport is off limits, and a significant proportion of implants need revision surgery over time.
What Limb-Salvage Surgery for Bone Tumours (Endoprosthetic Reconstruction) involves
Planning relies on MRI of the entire bone, CT of the chest, a bone or PET scan, and a biopsy placed by the same team so that the biopsy track can be removed at surgery. For osteosarcoma and Ewing sarcoma, about 10 weeks of chemotherapy usually come first. At operation, the surgeon exposes the tumour without entering it, protects the main nerves and vessels, and cuts the bone a planned distance beyond the tumour edge seen on MRI. The specimen is sent to pathology to confirm clear margins. Modular stems, body segments and a hinged or ball-and-socket joint are assembled to match the resected length and fixed into the remaining bone, with or without cement. Muscles are reattached to the implant, sometimes using a synthetic mesh sleeve, and a muscle flap may be rotated to cover the prosthesis.
Who is a good candidate for Limb-Salvage Surgery for Bone Tumours (Endoprosthetic Reconstruction)?
Suitability is decided by a sarcoma tumour board; the operation should be done only in centres treating these rare cancers regularly.
- Primary malignant bone tumours of the femur, tibia, humerus or pelvis that can be removed with clear margins
- Tumours that have responded to pre-operative chemotherapy
- Aggressive benign tumours, such as giant cell tumour, that have destroyed a joint
- Solitary or limited bone metastases, for example from kidney cancer, with a fracture or impending fracture and a reasonable outlook
It is usually not the right choice if:
- Tumours encasing the main nerves and vessels such that a functional limb cannot be preserved, where amputation or rotationplasty may serve better
- Tumours progressing through chemotherapy with no achievable clear margin
- Active infection in the limb
- Very young children with much growth remaining may be better served by rotationplasty or biological reconstruction than by repeated implant lengthening
- Widespread metastatic disease with a short outlook, where simpler fixation and radiotherapy are kinder
الخيارات التقنية
- Modular endoprosthesis: Off-the-shelf components assembled in theatre. Allows early weight-bearing; the usual choice in adults.
- Expandable (growing) prosthesis: For children; lengthened periodically, in newer designs non-invasively with an external magnet.
- Biological reconstruction: Donor bone allograft, vascularised fibula transfer or the patient's own sterilised bone. Slower recovery but potentially longer-lasting in the young.
- Custom 3D-printed implants: Used for pelvic and unusual resections.
- Rotationplasty or amputation: Durable options when limb salvage would leave a poor or unsafe result.
ماذا يحدث خلال علاجك
Surgery lasts 3 to 8 hours under general anaesthesia, often with a nerve block or epidural. Blood transfusion is common. You wake with drains, and sometimes a brace. The first night may be spent in intensive care. Physiotherapy starts within a day or two, with walking on a frame for leg reconstructions as soon as the soft tissues allow.
الإعداد لرحلتك
Plan for 3 to 5 weeks for surgery alone; months if chemotherapy is given there in Istanbul. Your surgeon reviews photographs and your medical history before you book, and you meet in person the day before surgery for examination, marking and consent with a professional interpreter.
- Stop smoking and nicotine at least four weeks before and after surgery; it is the single biggest avoidable cause of wound problems
- Tell the team about every medicine and supplement you take; blood thinners, some herbal products and hormone treatment may need to be paused on your doctor's advice
- Arrange for someone to travel with you or to be reachable, and keep the first days at home free of work and lifting
- Book a changeable return flight; your surgeon confirms when you are fit to fly
التعافي والنتائج
Hospital stay is usually 7 to 14 days. Chemotherapy typically resumes 2 to 3 weeks after surgery once the wound has healed. Crutches are needed for 6 to 12 weeks, and rehabilitation continues for 6 to 12 months; after knee-region resections, regaining active knee extension takes patience. Follow-up includes limb X-rays and chest imaging every 3 months for the first 2 years, then less often for at least 10 years.
- Back to everyday activity: 3 to 6 months
- When results show: Walking with aids within days; function improves over 6 to 12 months
- How long they last: Implant revision is likely within 10 to 20 years
سياسة السلامة والمخاطر والتنقيح
These are large operations in patients often weakened by chemotherapy, and complication rates are higher than after ordinary joint replacement.
- Deep infection of the implant in about 8 to 15 percent, sometimes requiring staged revision or amputation
- Local recurrence of the tumour in roughly 5 to 10 percent
- Aseptic loosening, wear or breakage of the prosthesis, with revision needed in a third or more within 10 to 15 years
- Wound healing problems, especially on chemotherapy
- Nerve or vessel injury causing weakness, foot drop or, rarely, loss of the limb
- Dislocation after hip or shoulder region reconstruction
- Leg length difference in growing children
- Blood clots in the legs or lungs

الأسئلة المتكررة
Is limb salvage as safe as amputation for curing the cancer?
When clear margins are achievable, survival is equivalent. If margins would be compromised, amputation can be the safer choice.
Can surgery abroad fit in with chemotherapy at home?
It can, but timing is tight: surgery falls in a planned gap of about 2 to 3 weeks between chemotherapy blocks. Both teams must agree the schedule in writing beforehand, and the pathology report on chemotherapy response must reach your oncologist quickly.
What activities will be possible?
Walking, swimming, cycling and driving are usual goals. Running and contact sports shorten implant life and are discouraged.
What about a child who is still growing?
Options include growing prostheses, biological reconstruction and rotationplasty. Each has different long-term demands, so seek an opinion from a paediatric sarcoma team.
