Osteochondroma is a tumor that can occur in bones and cartilages. Usually found in the long bones, these benign tumors frequent the shoulder or knee. Occurring frequently in young males, these tumors cause lesions leading to deformity of the bone.

Signs and Symptoms

Primary symptoms of osteochondroma include pain due to the intruding lesion or presence of a painless mass around the bone. These lesions and tumors can also cause spontaneous fractures due to the pressure on the bone.


  • Asymptomatic osteochondroma needs no treatment. If the tumor or lesion intrudes into the bone or cartilage it causes pain and some neurologic symptoms. In such a case the lesion can be cut off at the base. In some cases the knee cap may also require excision to prevent recurrent growth of the tumor or lesion. Patients with multiple osteochondromas need to be screened as often as required for monitoring the growth and removal of excess growth if any.
  • As this is an uncomplicated surgery, the side effects are very few and subside with time.


Though the exact cause of osteochondroma is not known, it has been proved to follow a strong hereditary pattern. Depending on how dominant it is the condition can lead to single or multiple osteochondroma.

Tests & Procedures

Simple X-rays are too primitive to diagnose the condition. Other imaging techniques such as ultrasound scan, CT scan, MRI scan and the like are better ways of reaching a conclusion. Histopathological studies of the bone biopsy show if the bone cell is cancerous. It also helps in understanding the nature of the cancer and its advancement.
