Here is the summary of replies for the original posting.


Can anyone point me to some journal articles about the uses of Jewett
(hyperextension) braces for thoracic fractures?

I read in atlas of orthoses that the best effect of jwett brace is in
UNSTABLE FRACTURE from T6 to L1.
-----------------------
A good source of information about many different braces is the Atlas
of Orthotics, Biomechanical Principles and Application, 2d Edition. The
Jewett brace applies forces more superiorly, motions are restricted in the
thoracic and upper lumbar areas. Flexion-extension restriction in these
areas produces a compensatory increase in motion at the lower lumbar spine
and lumbosacral junction. The three-point force system restricts forward
flexion in the thoracolumbar area and encourages a hyperextension posture,
which increases lumbar lordosis. It tends to stabilize (lock) the spine
against lateral and rotary movements. Flexion control and hyperextension
posture are achieved by the pads only; the frame should not contact the
patient.
