7 Kind of injury, disease or death to which this Statement of Principles relates
(1) This Statement of Principles is about thoracolumbar spondylosis and death from thoracolumbar spondylosis.
(2) This Statement of Principles applies to thoracolumbar spondylosis that has been diagnosed on the basis of:
(a) clinical manifestations of local pain and stiffness, or symptoms and signs of thoracolumbar cord or thoracolumbar nerve root compression; and
(b) imaging evidence of degenerative change, including disc space narrowing or osteophytes.
Note: imaging evidence of degenerative change is defined in the Schedule 1 Dictionary. It will usually be the case that the date of the imaging evidence of degenerative change is after the date of clinical onset.
(3) For the purposes of this Statement of Principles "thoracolumbar spondylosis" means a degenerative joint disorder affecting the thoracolumbar vertebrae or intervertebral discs including spondylosis at the thoracolumbar and lumbosacral junctions.
(4) The definition of thoracolumbar spondylosis given at subsection (3) excludes diffuse idiopathic skeletal hyperostosis, Scheuermann disease and bulging of an intervertebral disc in the absence of other signs of disc degeneration.
(5) Other commonly associated features of thoracolumbar spondylosis include facet joint arthritis, bone hypertrophy and spinal stenosis.
(6) Thoracolumbar spondylosis attracts ICD‑10‑AM codes M47.14, M47.15, M47.16, M47.17, M47.24, M47.25, M47.26, M47.27, M47.84, M47.85, M47.86, M47.87, M47.94, M47.95, M47.96, M47.97 or M51.3, in applying this Statement of Principles the meaning of thoracolumbar spondylosis is that given in subsection (3).
(7) In this Statement of Principles, the definition of "thoracolumbar spondylosis" is that given at subsection (3).
(8) For subsection (6), a reference to an ICD-10-AM code is a reference to the code assigned to a particular kind of injury or disease in The International Statistical Classification of Diseases and Related Health Problems, Tenth Revision, Australian Modification (ICD-10-AM), Tenth Edition, effective date of 1 July 2017, copyrighted by the Independent Hospital Pricing Authority, ISBN 978-1-76007-296-4.
Death from thoracolumbar spondylosis
(9) For the purposes of this Statement of Principles, thoracolumbar spondylosis, in relation to a person, includes death from a terminal event or condition that was contributed to by the person's thoracolumbar spondylosis.
Note: terminal event is defined in the Schedule 1 – Dictionary.
8 Basis for determining the factors
The Repatriation Medical Authority is of the view that there is sound medical-scientific evidence that indicates that thoracolumbar spondylosis and death from thoracolumbar spondylosis can be related to relevant service rendered by veterans, members of Peacekeeping Forces, or members of the Forces under the VEA, or members under the MRCA.
Note: MRCA, relevant service and VEA are defined in the Schedule 1 – Dictionary.
