The pedicle and disc are used as reference points to describe disc herniations.
Case Discussion
The pedicle and disc are used as reference points to describe disc herniations which may extend to:
- disc level - confined to between the vertebral endplates
- suprapedicular - between superior endplate and superior border of pedicle
- pedicular - at the level of the pedicle
- infrapedicular - below lower margin of the pedicle to the inferior endplate
