Materials
Technology has provided us with new
opportunities to solve old problems. Designs of the past had
to rely on the materials available at the time. In a sense,
the materials dictated the designs. As new materials were
introduced, the old designs persisted. Materials alone do
not improve function in an orthosis; however, these new
materials provide the basis for new and different designs.
Conventional thinking must be replaced with innovation in
order to create a more functional orthosis. There cannot be
progress without change.
The materials used to make an orthosis
must satisfy the requirements of the design and the intended
outcome. Carbon composites offer the unique qualities of the
rigid support needed for triplanar control and flexibility
for dynamic function. Composites may include materials other
than carbon that can enhance function. Carbon alone is very
rigid. Strength must be combined with flexibility to improve
function.
Composites allow the designer to combine
materials in one device to create superior performance
characteristics. Only research and development will
determine the optimal blend of materials. It is important
that the attempt be made. There will be no future if we
remain in the past. Materials science will ultimately affect
the design of an orthosis.
