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

Our services aim to keep the clinician, research worker and rehabilitation professional in touch with the published literature in a variety of easy to use and convenient formats.
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.
