A new motor-driven percutaneous bone biopsy system: technical note.
A new coaxial needle system was designed for percutaneous puncture of osteoclerotic lesions. Driven by a conventional motor unit, the instrument allows safe guidance even where difficult biopsy routes are used, and has been shown to penetrate radiopaque lesions. Preliminary clinical results from 29 patients are presented. The specimens obtained yielded a correct diagnosis in 28 cases. No major complications were observed.
