6 Definitions
The terms defined in the Schedule 1 - Dictionary have the meaning given when used in this instrument.
7 Kind of injury, disease or death to which this Statement of Principles relates
(1) This Statement of Principles is about thoracolumbar intervertebral disc prolapse and death from thoracolumbar intervertebral disc prolapse.
(2) This Statement of Principles applies to thoracolumbar intervertebral disc prolapse that has been diagnosed on the basis of:
(a) clinical manifestations of local pain and stiffness, or symptoms and signs of thoracolumbar spinal cord compression or thoracolumbar nerve root compression; and
(b) imaging evidence of thoracolumbar intervertebral disc prolapse, including protrusion, herniation, extrusion or rupture of the nucleus pulposus or annulus fibrosis of a thoracolumbar intervertebral disc into the vertebral canal of the thoracolumbar spine.
Note: imaging evidence of thoracolumbar intervertebral disc prolapse is defined in the Schedule 1 - Dictionary. It will usually be the case that the date of the imaging evidence of thoracolumbar intervertebral disc prolapse is after the date of clinical onset.
(3) For the purposes of this Statement of Principles "thoracolumbar intervertebral disc prolapse" means protrusion, herniation, extrusion or rupture of the nucleus pulposus or annulus fibrosis of an intervertebral disc into the vertebral canal of the thoracolumbar spine, causing symptoms or signs, including intervertebral disc prolapses at the thoracolumbar and lumbosacral junctions.
(4) The definition of thoracolumbar intervertebral disc prolapse given at subsection (3) excludes bulging of the intervertebral disc and Schmorl's nodes.
(5) Whilst thoracolumbar intervertebral disc prolapse attracts ICD‑10‑AM codes M51.0, M51.1 or M51.2. In this Statement of Principles, the definition of "thoracolumbar intervertebral disc prolapse" is that given at subsection (3).
(6) For subsection (5), 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 intervertebral disc prolapse
(7) For the purposes of this Statement of Principles, thoracolumbar intervertebral disc prolapse, in relation to a person, includes death from a terminal event or condition that was contributed to by the person's thoracolumbar intervertebral disc prolapse.
Note: terminal event is defined in the Schedule 1 – Dictionary.
8 Basis for determining the factors
On the sound medical‑scientific evidence available, the Repatriation Medical Authority is of the view that it is more probable than not that thoracolumbar intervertebral disc prolapse and death from thoracolumbar intervertebral disc prolapse can be related to relevant service rendered by veterans 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.
9 Factors that must exist
At least one of the following factors must exist before it can be said that, on the balance of probabilities, thoracolumbar intervertebral disc prolapse or death from thoracolumbar intervertebral disc prolapse is connected with the circumstances of a person's relevant service:

1 Definitions
In this instrument:
being obese means having a Body Mass Index (BMI) of 30 or greater.
Note: BMI is also defined in the Schedule 1 - Dictionary.
BMI means W/H2 and where:
(a) W is the person's weight in kilograms; and
(b) H is the person's height in metres.
clinical onset means the point backwards in time from the first date of imaging confirming thoracolumbar intervertebral disc prolapse, to the date at which the symptoms of thoracolumbar intervertebral disc prolapse were persistently present, as assessed by a registered medical practitioner.
imaging evidence of thoracolumbar intervertebral disc prolapse means an image of the interior of a body obtained by medical techniques, including X-ray radiography or magnetic resonance imaging, showing thoracolumbar intervertebral disc prolapse, that is usually obtained at a date after the date of clinical onset of the disease.
Note: clinical onset is defined in the Schedule 1 – Dictionary.
Load-Factor means W2 x T, where:
(a) W is the weight of the load lifted or carried in kilograms; and
(b) T is the time the load was lifted or carried in hours.
motor vehicle means a motorised vehicle which imparts vibration to the whole body, such as a car, truck, motor cycle, tractor, jeep, armoured personnel carrier, tank, or a construction vehicle, such as a forklift, bulldozer, crane, steam shovel, backhoe or steam roller.
MRCA means the Military Rehabilitation and Compensation Act 2004.
one pack-year means the amount of tobacco consumed in smoking 20 cigarettes per day for a period of 1 year, or an equivalent amount of tobacco products.
Note 1: An equivalent amount of tobacco products is 7,300 grams of smoking tobacco by weight, either in cigarettes, pipe tobacco or cigars, or a combination of same. For pipe tobacco, cigars or combinations of multiple tobacco types, 1 gram of tobacco is considered to be equal to one cigarette.
Note 2: Pack-years are calculated by dividing the number of cigarettes smoked per day by 20 and multiplying this number by the number of years the person has smoked. For example, smoking 10 cigarettes per day for 10 years is equal to 5 pack-years, and smoking 40 cigarettes per day for 10 years is equal to 20 pack-years.
penetrating injury to the affected intervertebral disc or adjacent vertebral body means piercing of the affected intervertebral disc or adjacent vertebral body by an object such as a bullet, shell fragment, knife or needle.
relevant service means:
(a) eligible war service (other than operational service) under the VEA;
(b) defence service (other than hazardous service and British nuclear test defence service) under the VEA; or
(c) peacetime service under the MRCA.
Note: MRCA and VEA are also defined in the Schedule 1 - Dictionary.
terminal event means the proximate or ultimate cause of death and includes the following:
trauma to the affected intervertebral disc means a discrete event involving the application of significant physical force to the affected intervertebral disc, that causes:
(a) the development of symptoms and signs of pain and tenderness, and either altered mobility or range of movement of the thoracolumbar spine. In the case of sustained unconsciousness or the masking of pain by analgesic medication, these symptoms and signs must appear on return to consciousness or the withdrawal of the analgesic medication; and
(b) the persistence of these symptoms and signs for a period of at least 7 days following their onset, save for where medical intervention for the trauma to the affected intervertebral disc has occurred and that medical intervention involves one of the following:
(i) immobilisation of the thoracolumbar spine by splinting or similar external agent;
(ii) injection of a corticosteroid or local anaesthetic into the thoracolumbar spine; or
