Osteoid osteoma is a benign neoplasm of bone. Osteoid osteoma occurs more often in men. The age range is from 2 to 50 years, but 90% occur before the age of 25 (1,2). Osteoid osteoma produces local pain that is worse at night and improves dramatically with aspirin. The presence of nerve fibers within the tumor nidus and the stimulatory role of prostaglandins are thought to produce the pain. The characteristic findings of this tumor in clinical and radiologic examinations can lead to a high level of diagnostic confidence in many instances. The treatment of this tumor is achieved with the complete removal of the nidus. Conventional treatment is surgical or percutaneous excision of the nidus. Less invasive techniques such as computed tomography (CT)-guided core drill excision (3-9), radio-frequency ablation (10-17), alcohol injection (18), or interstitial laser photocoagulation (ILP) (19-22) have been used. ILP was a technique first described in 1983 (23). In vitro and experimental animal studies showed the production of a predictable size of tissue coagulation by the use of bare optical fibers with a low-power (typically 2-4 W) laser technique. A thin optical fiber is inserted percutaneously into the tumor, which is then coagulated and destroyed by direct heating. The ability to control the treated area with a high degree of precision, applicability in joints, and an excellent dose-response characteristic makes ILP a valuable treatment method for osteoid osteomas. This technique has been applied clinically to treat tumors of liver, pancreas, prostate, brain, breast, and lymph nodes (24-30).

Deal With Your Pain, Lead A Wonderful Life An Live Like A 'Normal' Person. Before I really start telling you anything about me or finding out anything about you, I want you to know that I sympathize with you. Not only is it one of the most painful experiences to have backpain. Not only is it the number one excuse for employees not coming into work. But perhaps just as significantly, it is something that I suffered from for years.
