Osteochondroma is an overgrowth of cartilage and bone at the end of the bone near the growth plate. It often occurs in a long bone of the body, the femur, shoulder blade, and pelvis. This is the most common noncancerous bone growth. This is common between the ages of 10 and 30, regardless of gender.


The exact cause of osteochondroma is still unkonown. It can be both genetic and non-genetic, making it difficult to determine.


  • Painless lump near the joint: This occurs most often near the knee and shoulder.
  • Numbness or Tingling:  When an osteochondroma is located near a nerve, such as behind the knee, if the tumor puts pressure on the nerve, numbness and tingling in the associated limbs may occur.
  • Pain with Activity : An osteo-chondroma is located under a tendon (tough, fibrous tissue that connects muscle to bone). When that happens, the tendon moves and snaps over the bone, causing pain.
  • Changes in blood flow :  A tumor pressing on a blood vessel can cause changes in blood flow. This can cause loss of pulse or discoloration of the leg. Changes in blood flow caused by osteo-chondroma are rare.
  • Less than average height for age
  • Pain in nearby muscles

When they do occur, osteochondroma symptoms can look like other medical problems. Always talk to your doctor for a diagnosis.


  • X-ray – This test uses invisible radiation to make images of tissues, bones, and organs.
  • CT Scan (computed tomography scan)- This test uses X-rays and computer technology to make images (often called slices) of the body.
  • A CT scan shows detailed images of any body part, including bones, fat, muscles, and organs, and can provide detailed information about delicate tissues. CT scans are more detailed than regular X-rays.
  • MRI (Magnetic Resonance Imaging) – This test uses a large magnetic field, radio frequency, and a computer to create detailed images of the body’s organs and structures.
  • Biopsy – In some cases, a biopsy may be ordered to determine whether a tumor is cancerous. In a biopsy, a tissue sample of the tumor is taken and examined under a microscope. The doctor may take a sample using a needle to massage the area for you or your child. A biopsy may also be performed as a minor operation.
