15. Nucleus replacement
implants/ partial disc prosthesis
The optimal indication for artificial
nucleus replacement is
monosegmental degenerative
discopathy.
Lumbar pain should be the main
symptom.
For a PDN prosthesis, the disc
height should be at least 5 mm
For a PDN prosthesis,
the sagittal diameter of
the nucleus should be at
least 26 mm to allow
sufficient room for the
ventral and dorsal
implant.

16. Lumbar Intervertebral
Total Disc Replacement

17. SB Charité
The endplates
grip the adjoining bony
endplates by means
of three metal teeth,
which are attached
anteriorly and posteriorly
and run diagonally.

Design
HA Coating
• Calcium phosphorus
• Provides a geometry
which is conductive
to bony on growth
• Rough surface
provides increased
friction for a press fit
