While I believe that it would be very convenient for the research
community to have a library of 3D models of orthopaedic components
at their disposal, it is unlikely to occur for actual components
that are in the marketplace. I have created 3D CAD and finite
element models for 12 different manufacturers. Our lab has a
confidentiality agreement for each with very strict limits on the
use of their designer's CAD data as well as the CAD models that are
developed by reverse engineering their components. There is a
surprising amount of variation in design concepts between
manufacturers, and those design details are closely held by these
companies.
I think the concept of soliciting a few manufacturers to release
their "classic" designs to the research community along with
clinical data might be a reasonable compromise. Many of the classics
do not have 3D design CAD models but rather are specified with 2D
blueprints. This would require either reverse engineering of
components or building solid or surface models from the prints.
Maybe a company would be interested in allowing a classic model to
go public in return for a clean 3D model for their own internal
use...
Another avenue worth discussion: would the creation and posting of
generic 3D models of orthopaedic prosthetic components from general
dimensional information be of any benefit to the research community?
