Osteoid Osteoma

Osteoid osteoma is a small non-cancerous tumor that typically develops on the femur (thigh) or tibia (shin bone). It does not spread, but causes a bone to grow around it. It also creates an osteoid bone, which is abnormal bone material.


The cause of an osteoid osteoma is unknown.


Common signs and symptoms of osteoid osteoma are:

  • Dull or achy pain that worsens at night

  • Limping

  • Muscle atrophy (loss of muscle tissue)

  • Leg bowing deformity

  • Muscle spasms

  • Nerve symptoms

  • Growth disturbance


To determine if your child has osteoid osteoma, your specialized doctor may perform multiple tests such as:

  • Physical exam

  • Imaging tests such as X-rays, MRIs, CT scans or bone scans

  • Blood tests


Our expert doctors will determine the best course of treatment based on your child’s age, overall health, location of the tumor and other factors. Your child’s doctor will discuss all options for the best outcome for your child.
