Noncancerous Bone Tumors
Chondroblastomas
Chondroblastomas are rare tumors that grow in the ends of bones. They usually occur in people aged 10 to 20 years. These tumors may cause pain. To diagnose a chondroblastoma, doctors take x-rays and may do other imaging tests, such as Computed tomography (CT) and magnetic resonance imaging (MRI) (MRI). Doctors also remove a tissue sample for examination under a microscope (biopsy). If untreated, these tumors may continue to grow and destroy bone and the joint. Therefore, treatment consists of surgical removal and use of a bone graft (transplantation of bone tissue from one bone to another) to fill in the defect. Graft material can be bone removed from the person’s own pelvis (autograft), processed bone tissue from another person (allograft), or a synthetic bone substitute. Occasionally, these tumors return after surgery.
