Radiofrequency ablation in spinal osteoid osteoma : Options and limits.
Summary of "Radiofrequency ablation in spinal osteoid osteoma : Options and limits."
Osteoid osteoma was first described by Jaffe in 1935 as a benign bone neoplasm mainly located in the diaphyseal areas of long bones: 10% are located in the spine, mainly in the lumbar and thoracic posterior elements. Therapy is required due to nocturnal pain independent of the physical load and responds especially well to anti-inflammatory drugs due to the excessive production of prostaglandins in the nidus. Diagnosis is confirmed by multi-slice computed tomography (CT), magnetic resonance imaging (MRI) and skeletal scintigraphy scans. In cases with typical symptoms and imaging, open biopsies are rarely needed. Although CT-guided radiofrequency ablation is accepted as the gold standard treatment option for osteoid osteoma in the extremities, this technique is limited in spinal applications due to the risk of thermal damage to adjacent neurovascular structures. Technical advances in the administration of radiofrequency ablation have, however, resulted in new and expanded indications in the spine so that the necessity for open surgical excision of spinal osteoid osteoma is becoming less.

Medical and Biotech [MESH] Definitions
Benign circumscribed tumor of spongy bone occurring especially in the bones of the extremities and vertebrae, most often in young persons. (Dorland, 27th ed)
A benign tumor composed of bone tissue or a hard tumor of bonelike structure developing on a bone (homoplastic osteoma) or on other structures (heteroplastic osteoma). (From Dorland, 27th ed)
Removal of tissue by vaporization, abrasion, or destruction. Methods used include heating tissue by hot liquids or microwave thermal heating, freezing (CRYOABLATION), chemical ablation, and photoablation with LASERS.
Patient Protection And Affordable Care Act
An Act prohibiting a health plan from establishing lifetime limits or annual limits on the dollar value of benefits for any participant or beneficiary after January 1, 2014. It permits a restricted annual limit for plan years beginning prior to January 1, 2014. It provides that a health plan shall not be prevented from placing annual or lifetime per-beneficiary limits on covered benefits. The Act sets up a new competitive health insurance market giving tens of millions of Americans the same choices of insurance that members of Congress will have. It aims to bring greater accountability to health care and to control cost of health insurance premiums.
The 31 paired peripheral nerves formed by the union of the dorsal and ventral spinal roots from each spinal cord segment. The spinal nerve plexuses and the spinal roots are also included.
