​Chondroblastoma


Chondroblastoma, also called the Codman’s tumour, is a rare benign (noncancerous) tumour that develops in the cartilage, a flexible connective tissue from which most bones grow. This tumour mostly develops within the end of the long bones, such as in the arms at the shoulder, and in the legs at the hip and knee. The exact cause of chondroblastoma is not known, but it is thought to develop from the growth plates, a small section of the cartilage important for bone growth, which is present at the end of the long bones. 

It can affect people of any age but is mostly found in children and young adults. It is more prevalent in men than in women. Chondroblastoma is one of those rare tumours that have the potential to spread to the lungs.

Symptoms due to chondroblastoma depend on their location in the body. However, the most common symptom you may encounter is pain. Other symptoms include:

  • Joint stiffness

  • Withered or shrunken appearance of the muscle near affected bone

  • A limp

You can consult one of our highly esteemed doctors working with the Musculoskeletal and Sports Medicine Service Line at The Aga Khan University Hospital the only internationally accredited hospital in Pakistan, if you experience any of the above mentioned symptoms.

Your time with your doctor maybe limited, so make sure to prepare for your visit beforehand. Here are some tips to help get you started.

Your doctor may begin the diagnosis by inquiring about your medical history and performing a physical exam to look for tenderness over the bone. Following this you may be asked to undergo the following tests:

  • X-rays in which a small amount of radiation will be used to generate an image of the bones and organs to detect the presence of tumour

  • CT (Computerized Tomography) scans in which a series of detailed images, of the body, will be taken by a computer. This is done to produce a more detailed image

  • MRI (Magnetic Resonance Imaging) scans in which a series of detailed images of the body will be made on the computer using a magnet and radio waves. This is done to produce better images of soft tissues

  • Biopsy in which a tissue sample of the tumour will be extracted to be studied under the microscope

Pain due to Chondroblastoma can be persistent and disturbing. At the Musculoskeletal and Sports Medicine Service Line at The Aga Khan University Hospital your doctor’s goal will be to ease this pain by removing the tumour and preventing damage to the bone end. Your treatment options will include:

  • Curettage: the tumour will be scrapped out of the bone. Recurrence of tumour after this procedure is rare.

  • Bone graft: performed after the curettage to fill the hole left behind by the tumour, in which a healthy bone will be transplanted from another part of the body, or from a donor, into the affected area.

  • Resection: the entire section of the affected bone will be removed. If the tumour spreads to the lungs or other organs, the compromised areas of the organs may also be removed.

  • Physical therapy: to restore strength and function post-surgery.
