[Minimally invasive therapy for osteoid osteoma].
OBJECTIVE
We describe a minimally invasive procedure for the treatment of osteoidosteoma and present the outcome of the treatment in our collective. Additionally, a review of the literature for minimally invasive therapy for osteoidosteoma was performed.


METHODS
Within approximately three years, ten male patients with the clinical and radiological diagnosis of osteoidosteoma were treated. First, during the procedure for the purpose of orientation, a CT scan of the affected area was performed. Then, under CT-guidance, the nidus of the osteoidosteoma was marked with a k-wire and destroyed with a drill, moulding cutter or the k-wire. The patients' charts and films were reviewed in a retrospective manner, all patients participated in a personal telephone interview.


RESULTS
In all cases the intraoperative course was free of complications. After surgery 90 % of the patients were free of pain, in 10 % a significant reduction of the pain was reported. Both in those 10 % and the whole collective there were no clinical symptoms of relapse, the average follow-up in all cases was 19 months. Our results are in accord with data in the literature.


CONCLUSIONS
In our collective the CT-guided, percutaneous removal of osteoidosteoma has been shown to be a safe and effective method. Under DRG conditions it can be performed within a short period of hospitalization or in the out-patient clinic.
