Chondroblastoma

• Chondroblastoma is an unusual type
  of noncancerous bone tumour that develops in bone
  cartilage. Chondroblastoma is also referred to as
  a Codmans 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.

Symptoms

• The symptoms of Chondroblastoma depend upon the
  location of the tumour. If your child experiences
  any of the following symptoms, consult a
  nearby oncologist. 
• Accumulation of fluids in the joints
• Persistent pain in the hip, shoulder, and knee
  joint
• Frequent contraction in the affected muscles
• Restricted movements of the joints
• Excessive swelling and inflammation

Diagnosis of Chondroblastoma

• After examining a patients 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 
• X-RAY
• Ultrasound
• Magnetic Resource Imaging (MRI)
• Blood test
• Biopsy or tissue sample
• Computer Tomography (CT scan)

Treatments

• 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.
