Long-term efficacy of percutaneous drill-biopsy under computed tomography guidance of osteoid osteomas of the hip and femur. A review of seven cases.

Unlabelled: En bloc surgical excision of osteoid osteomas of the hip and femur is difficult because of problems with tumor boundary identification and the need to use internal fixation or bone grafting. We report our experience with seven cases treated by percutaneous drill-biopsy under computed tomography guidance.

Patients: Six adults and one child with a mean age of 22 years treated since 1995.
