Osteoid Osteoma

An osteoid osteoma is a benign (non cancerous), small tumor that usually grows in the long bones of a person's legs. The thighbone is the most common location, although it can occur in the bones of the hand and in the lower part of the spine.

• The tumor may be very painful, but it doesn't spread.
• The tumor causes functional limitations that used to require surgery and physical therapy.
• In young children, it may deform the bone or stimulate the bone to grow larger or longer.
• It usually appears in children, adolescents and young adults.
• Its cause is unknown.
• The most common treatment uses radio frequencies to kill the tumor.
• The procedure is an outpatient procedure. Most patients can resume normal activity within a week.
• Treatments usually are successful, but the tumors can come back.
• Radiofrequency ablation (RFA) is effective in 94 percent of first attempts and 100 percent if a second procedure is required.
