THE DEMONSTRATOR MANUFACTURING

The demonstrator has proven both the manufacturability of the parts (small parts with

details and complex shapes) and its capability be assembled and to provide a firm grip to

the vertebrae, avoiding sliding.

PROTOTYPE REQUIREMENTS FULFILLMENT

The prototype (full process) has proved:

• The possibility of obtaining a 3D model from

patient scanner with a resolution enough to

build a detail FEM of the spine.

• The feasibility of building a FEM

representative enough of the spine behaviour

has to be proved

• The feasibility of reducing the number of

implants with the same correction results

• The possibility of replacing the current

implants with a new prosthetics that improve

performance and assembly process

FUTURE RECOMMENDATIONS

Some development has still to be implemented in order

to pass from prototype to service provision:

• To spread the analysis to different use cases.

• To design different attachments for different areas of

the spine

• To parametrize the FEM and optimization phases

• To build a titanium prototype

• To set a run of functional tests in patients with

optimized implants
