[Biopsy of the vertebral body using a posterior transpedicular approach]

The technique of biopsy of the vertebral body through a posterior approach passing through the pedicle was first reported in 1963. A description of the technique is given. The importance of good radiological control is stressed. Biopsy can be made with a curette once the approach has been made with a drill. The results were positive in 46 cases out of 47. A false negative was found on only one occasion.
