How effective is tumour removal surgery for osteosarcoma?

Osteosarcoma often develops in a long bone near a joint. The operation may remove the affected bone and reconstruct it with a prosthesis, graft or another technique. Limb-sparing surgery is considered when the tumour can be removed without making the limb unsafe or unusable; amputation may be discussed when major vessels, nerves or extensive tissue are involved. Surgery is commonly planned alongside chemotherapy, because microscopic cancer cells may remain outside the visible mass. Imaging helps the team map the tumour and check for spread, while the laboratory examines the removed tissue and margins.

Ask the sarcoma team how the tumour touches nearby joints, nerves and blood vessels, and whether reconstruction will be needed. Discuss how surgery fits with chemotherapy, the expected hospital stay, physiotherapy and the time before putting weight through the limb. Bring up pain control, wound care, mobility aids and how treatment may affect school, work or sport. A second opinion from a specialist sarcoma centre can help when the operation is complex.

After surgery, contact the treating team promptly for fever, worsening redness or drainage, sudden swelling, uncontrolled pain, new numbness, a cold or pale limb, chest pain or breathlessness. These symptoms can signal infection, a circulation problem, a clot or another complication that needs assessment. Do not wait for a routine appointment if a wound opens or you cannot move the limb as instructed.

Which structures must be removed or protected? What margin is planned? Will I need reconstruction or amputation? How will chemotherapy be timed around surgery? What changes should prompt an urgent call during recovery?
