What is osteoblastoma?

An osteoblastoma is a rare non-cancerous tumor of bone that affects teenage boys more often than girls and most often occurs in the lower spine.
Non-cancerous tumors don’t spread to other parts of the body, but can invade surrounding tissue. Osteoblastomas can also be found in the long bones of the arm & legs, and hands and feet.

What causes osteoblastoma? 

It’s unclear what causes osteoblastoma.

What are the symptoms of osteoblastoma?

Osteoblastomas tend to be slow growing. As the tumor grows, it can initially lead to mild swelling and pain.
Over time, if the tumor is in the spine, symptoms may include:
  • Back pain
  • Nerve pain
  • Scoliosis (curvature of the spine)
  • Muscle weakness
  • Muscle spasms

What are osteoblastoma care options? 

Surgical removal is the treatment of choice; rarely however because of a tumor’s position radiation and/or chemotherapy may be recommended.

Ryan's ACL Surgery Success Story
01/24/2018 — Our 10 year old son, Ryan, tore his Anterior Cruciate Ligament (ACL) in his left leg this past summer. I have frequently been asked, isn’t 10 years old very young to tear an ACL? Yes, for children that young, it is rare, but not unheard of.  And for adolescents and teenagers, ACL injuries are occurring more frequently, likely due to early sport specialization, and the increase in travel sports and year-round training.
