“…Due to the proximity to nervous structures, treating osteoid osteomas near the spinal column constitutes a special situation. However, multiple studies have shown that RFA is also a safe method of therapy for spinal osteoid osteomas [37,38]. Both studies achieved absence of pain in 79 % of cases following initial RFA.…”

“…Both studies achieved absence of pain in 79 % of cases following initial RFA. Nervous structures can be isolated and cooled using air or carbon dioxide (CO2), or can alternatively be displaced with glucose or sterile water [37]. If the space-occupying aspect of the osteoid osteoma results in a compression of the nerve root, then surgery is indicated for the osteoid osteoma [38].…”

!Purpose: To review the long term clinical outcomes in the treatment of osteoid osteoma (OO) using radiofrequency ablation (RFA). Materials and Methods: Our retrospective study included 59 patients who were treated in the period from April 2001 to December 2012 due to a symptomatic OO using RFA. Here, the occurrence of complications and postoperative recurrence, as well as postoperative patient satisfaction were examined. Patients satisfaction was assessed by means of a telephone interview with the visual analogue scale (VAS). Results: Mean follow-up was 50 months (2 -116 months). The average size of the nidus was 6 mm (range 2 -14 mm). After initial radiofrequency ablation 11.8 % (7/59) of patient showed a recurrence of symptoms. Symptoms could successfully be treated by a second ablation in 5 patients. Assisted success rate was therefore 96.6 % (57/59). The complication rate was 5.1 % (2 major and one minor complication). Furthermore we report a very high patient satisfaction and acceptance of therapy. Conclusion: RFA is a very successful therapy of symptomatic OOs with a high patient satisfaction.

“…Other percutaneous techniques have been proposed, such as laser thermal therapy, cryotherapy, and ethanol therapy [1,2,26,27]. CT-guided RFA has become the preferred method owing to a low morbidity rate, minimal postoperative complications, minimal tissue exposure, rapid recovery, and no restriction of weightbearing activity [10,14,33,50,60,69]. In addition, the healing rate is 76% to 100% [14,53], with a major complication rate of 0% to 5% [2,6,45].…”

Background Osteoid osteomas consist of a nidus surrounded by reactive sclerotic bone. The diagnosis typically is based on imaging and clinical presentation involving nocturnal pain. Removal of the lesion is essential and currently is performed mainly with image-guided, minimally invasive techniques. We describe a case involving an osteoid osteoma of the acetabular fossa, treated with arthroscopy-assisted radiofrequency ablation. Case Description A 47-year-old woman presented with a 9-month history of right groin pain and limited motion. The CT and MR images showed synovitis around the ligamentum teres and a nidus of the acetabular fossa, surrounded by sclerotic bone and protruding from the inner part of the lamina quadrilateral. Synovectomy and debridement of the ligamentum teres were performed, followed by radiofrequency ablation of the osteoid osteoma under direct arthroscopic observation of the hip, avoiding resection of the normal bone around the nidus and preserving the integrity of the quadrilateral lamina and cartilage. The patient had complete pain relief the next day with minimal morbidity and rapid functional restoration. At the 22-month clinical followup, the patient was asymptomatic, and the CT and MR images obtained 1 year after surgery showed no pathologic signs or synovitis. Literature Review Our case was the fifth such case to be treated with hip arthroscopy and the first of these to our knowledge to be treated with the arthroscopy-assisted radiofrequency ablation technique. Purposes and Clinical Relevance Arthroscopy-assisted radiofrequency ablation is a combined treatment technique that may be used for intraarticular lesions of the hip that otherwise would require a difficult approach and jeopardize damage to cartilage and bone and also treat concomitant synovitis.

“…3 In some RF ablation, laser ablation, and cryoablation procedures with posterior wall destruction, gases injected into the spinal canal successfully displaced and insulated the spinal cord, preventing neurological damage. 4 Interstitial ultrasound ablation may have advantages over other ablation modalities in settings involving bone. Unlike RF ablation, laser ablation, and cryoablation, interstitial ultrasound can be applied with directional control of heat deposition along the length and circumference of the applicator, and it can take advantage of the preferential heating that occurs along bone surfaces due to high ultrasound absorption.…”
