Purpose
The aim of this study was to evaluate the efficacy of image intensifier-guided percutaneous drilling destruction of the nidus as a minimally invasive surgery for osteoid osteoma (OO) of the proximal femur.
Background
OO is a painful, benign, small osteogenic bone tumor. For a long time, surgery was the only treatment for these lesions. Different minimally invasive therapeutic techniques have been proposed.
Patients and methods
Between 2009 and 2011, 14 patients (nine male and five female) with OO were treated at Mansoura University Hospitals by percutaneous drilling destruction of the nidus under image intensifier.
Results
All procedures were technically successful. Clinical success was achieved in 94.5% of patients. Only one patient had incomplete removal of the nidus. There were no other complications.
Conclusion
Image intensifier-guided percutaneous drilling destruction of the nidus is a safe, simple, and effective minimally invasive technique for the treatment of OO of the proximal femur.
