[Minimally invasive therapy for osteoid osteoma].

AIM: 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.
CONCLUSION: 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.
