Question

What is a bone cyst? How is it treated?

Answer

A bone cyst is a noncancerous, fluid-filled cavity within the bone. Bone cysts occur most often in children in the long bones of the arms and legs. The cause isn't known.

A bone cyst usually causes no symptoms. But sometimes a bone cyst can weaken the affected bone, which increases the risk of fracture. A bone cyst is often discovered only after a fracture occurs.

Treatment of a bone cyst, which is directed at preventing fractures, may include:

  • Corticosteroid medications
  • Injections of bone marrow aspirate
  • Surgical removal of the bone cyst
