This document discusses the role of technicians in orthopaedic surgery and spinal surgery evolution. It lists 10 factors associated with spinal surgery evolution, including bioengineering, implants, operation rooms, training, and financial factors. It then provides details on various spinal implants, procedures, technologies, and the role of technicians in training and workshops. In particular, it emphasizes the technician's role in spinal surgeries, cervical arthritis procedures, and improving patients' quality of life through techniques like kyphosis and scoliosis correction and treatment of osteoporotic fractures.

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.

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.

• Calcium phosphorus
• Provides a geometry
which is conductive
to bony on growth
• Rough surface
provides increased
