Osteoid Osteoma Print

What is osteoid osteoma?

Osteoid osteoma is a benign reactive bone formation and 1-1.5 cm in diameter.  A nidus of fibrous and vascular tissue and tissue surrounded by sclerotic bone regeneration is typically seen. Its incidence is 10% of all benign bone tumors. It is seen commonly between the ages of 5-20. Osteoid Osteoma is frequently observed in  proximal femur (the upper end of the thigh bone), the tibia (shin bone), the posterior elements of the spine and  humerus (arm bone).

What are the findings of osteoid osteoma?

The most common sign of Osteoid osteoma is pain, experienced particularly at night. The most important feature of this pain is being alleviated with the use of aspirin and other drugs antiemflamatuvar. If located in the epiphysis, joint pain, swelling as a result of synovitis.

How is the diagnosis of osteoid osteoma made?

Clinical and radiological diagnosis of osteoid osteoma is possible. The definitive diagnosis is made by pathological examination. Seeing about 1.5 cm in radiological radiolucent nidus and the surrounding extremely dense reactive bone tissue on plain radiographs is diagnostic. Sometimes nidus location can not be made directly on x-rays and Computed Tomography of the nidus is needed to determine the exact location.

 

What is the treatment of osteoid osteoma?

Osteoid osteoma does not show spread to other parts of the body. Surgical removal of the nidus or percutaneous radiofrequency ablation therapy in suitable cases provides a complete cure. Post-operatively, pain is typically completely over. Patients are followed for the development of localized epiphyseal bone. No recurrence observed after treatment.
