[The percutaneous CT-guided treatment of osteoid osteomas: a combined procedure with a biopsy drill and subsequent
Purpose:
The purpose of this study was the clinical evaluation of a percutaneous treatment modality in patients with an osteoidosteoma.
Patients And Methods:
6 patients with an osteoidosteoma of the upper (n = 1) and lower (n = 5) extremity which were confirmed on plain film radiographs and computed tomography underwent CT controlled drill biopsy of the nidus with subsequent injection of 96% ethanol into the biopsy channel to sclerose probably remaining remnants of the nidus. The procedure was started under local anaesthesia, but drilling of the nidus was carried out under a short general anaesthesia using ketamine.
Results:
The intervention was successful in all patients. No postinterventional infection occurred and no recurrence was observed in any of the patients in a follow-up time between 0.5 and 2 years.
Conclusion:
Although only 6 patients were treated until now, we conclude that this combined procedure using a bone biopsy system and the subsequent injection of alcohol is a safe and successful procedure for percutaneous treatment of osteoidosteoma.
