Chondroblastoma is an unusual type of noncancerous bone tumour that develops in bone cartilage. Chondroblastoma is also referred to as a Codman’s tumour. This rare disease can affect people of all ages, but is most common among children. There are various types of cartilage in the body. However, Chondroblastoma usually develops in the end of long bones such as upper arm bone, shinbone, or thighbone. If Chondroblastoma is not treated in its initial stages, it may develop into benign tumour, which can spread to the other parts of the body. Chondroblastoma often leads to severe weakening of bones and causes unbearable pain. Chondroblastoma increases the risk of arthritis resulting in excessive inflammation of joints.
Causes of Chondroblastoma
The exact cause of Chondroblastoma is not known by the doctors and researchers. However, it is possible that lack of production of cartilage cells called chondroblasts, may result in the development of tumour.
The symptoms of Chondroblastoma depend upon the location of the tumour. If your child experiences any of the following symptoms, consult a nearby oncologist.
Diagnosis of Chondroblastoma
After examining a patient’s complete medical history and conducting physical exam the doctor will order diagnostic tests which will help him to know the type of joint that has been affected. Diagnostic tests
for Chondroblastoma may include:
- Magnetic Resource Imaging (MRI)
- Blood test
- Biopsy or tissue sample
- Computer Tomography (CT scan)
The treatment of Chondroblastoma depends on the type of symptoms. The main aim for the treatment Chondroblastoma is to remove the tumour and prevent the affected bone from further damage. Various types of surgeries are performed for the removal of tumour from the bone. Surgical treatment of Chondroblastoma includes:
- Bone grafting- Is a surgical procedure, which involves grafting of healthy bone from the other part of the body into the affected area.
- En bloc resection- Is performed if the tumour is located in the pelvis or the sites near it. En bloc surgery removes the entire bone containing the tumour and inserts the pins or other hardware to maintain the structural integrity of the bone.
- Radiofrequency ablation- Sometimes it is impossible for the surgeon to reach the tumour, therefore, radiofrequency ablation is used for the removal of tumour. In this procedure, tumour cells are exposed to high frequency radio waves.
- Extended curettage- Is a surgery performed by an orthopaedic surgeon for the removal of excessive layers of cells around the Chondroblastma. This surgical procedure often reduces the risk of reappearance of tumour.
