De quervain tendinopathy
Meaning of de quervain tendinopathy: For the purposes of this Statement of Principles, de Quervain tendinopathy means entrapment of one or both tendons in the first extensor compartment of the radial side of the wrist, producing localised pain and tenderness that is exacerbated by movement of the thumb or wrist. (3) While de Quervain tendinopathy attracts ICD-10-AM code M65.4, in applying this Statement of Principles the meaning of de Quervain tendinopathy is that given in subsection (2). (4) For subsection (3), 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.
Reasonable Hypothesis (RH) — Statement of Principles No. 41 of 2019
At least one of the following factors must as a minimum exist before it can be said that a reasonable hypothesis has been raised connecting de Quervain tendinopathy or death from de Quervain tendinopathy with the circumstances of a person's relevant service:
- (1)performing repetitive activities or forceful activities using the affected hand or wrist, for a cumulative period of at least 500 hours within the six months before the clinical onset of de Quervain tendinopathy;
Note: forceful activities and repetitive activities are defined in the Schedule 1 - Dictionary.
- (2)having acute trauma involving the affected wrist or tendon, within the one year before the clinical onset of de Quervain tendinopathy;
Note: Examples of acute trauma include, but are not limited to, a laceration, puncture, heavy blow, fracture and crush injury.
- (3)being treated with or using growth hormone within the one year before the clinical onset of de Quervain tendinopathy;
- (4)being treated with a fluoroquinolone antibiotic within the six months before the clinical onset of de Quervain tendinopathy;
Note: Examples of fluoroquinolone antibiotics include, but are not limited to, ciprofloxacin, moxifloxacin, norfloxacin and ofloxacin.
- (5)being treated with an aromatase inhibitor within the one year before the clinical onset of de Quervain tendinopathy;
Note: Examples of aromatase inhibitors include, but are not limited to, anastrozole, exemestane and letrozole.
- (6)performing repetitive activities or forceful activities using the affected hand or wrist, for a cumulative period of at least 500 hours within the six months before the clinical worsening of de Quervain tendinopathy;
Note: forceful activities and repetitive activities are defined in the Schedule 1 - Dictionary.
- (7)having acute trauma involving the affected wrist or tendon, within the one year before the clinical worsening of de Quervain tendinopathy;
Note: Examples of acute trauma include, but are not limited to, a laceration, puncture, heavy blow, fracture and crush injury.
- (8)being treated with or using growth hormone within the one year before the clinical worsening of de Quervain tendinopathy;
- (9)being treated with a fluoroquinolone antibiotic within the six months before the clinical worsening of de Quervain tendinopathy;
Note: Examples of fluoroquinolone antibiotics include, but are not limited to, ciprofloxacin, moxifloxacin, norfloxacin and ofloxacin.
- (10)being treated with an aromatase inhibitor within the one year before the clinical worsening of de Quervain tendinopathy;
Note: Examples of aromatase inhibitors include, but are not limited to, anastrozole, exemestane and letrozole.
- (11)inability to obtain appropriate clinical management for de Quervain tendinopathy;
Aggravation-only factors: the factors in subsections 8(6) to 8(11) apply only to material contribution to, or aggravation of, the condition where it was suffered or contracted before or during (but did not arise out of) the person’s relevant service.
Balance of Probabilities (BoP) — Statement of Principles No. 42 of 2019
11 factors
At least one of the following factors must exist before it can be said that, on the balance of probabilities, de Quervain tendinopathy or death from de Quervain tendinopathy is connected with the circumstances of a person's relevant service:
- (1)performing repetitive activities or forceful activities using the affected hand or wrist, for a cumulative period of at least 500 hours within the six months before the clinical onset of de Quervain tendinopathy;
Note: forceful activities and repetitive activities are defined in the Schedule 1 - Dictionary.
- (2)having acute trauma involving the affected wrist or tendon, within the one year before the clinical onset of de Quervain tendinopathy;
Note: Examples of acute trauma include, but are not limited to, a laceration, puncture, heavy blow, fracture and crush injury.
- (3)being treated with or using growth hormone within the one year before the clinical onset of de Quervain tendinopathy;
- (4)being treated with a fluoroquinolone antibiotic within the six months before the clinical onset of de Quervain tendinopathy;
Note: Examples of fluoroquinolone antibiotics include, but are not limited to, ciprofloxacin, moxifloxacin, norfloxacin and ofloxacin.
- (5)being treated with an aromatase inhibitor within the one year before the clinical onset of de Quervain tendinopathy;
Note: Examples of aromatase inhibitors include, but are not limited to, anastrozole, exemestane and letrozole.
- (6)performing repetitive activities or forceful activities using the affected hand or wrist, for a cumulative period of at least 500 hours within the six months before the clinical worsening of de Quervain tendinopathy;
Note: forceful activities and repetitive activities are defined in the Schedule 1 - Dictionary.
- (7)having acute trauma involving the affected wrist or tendon, within the one year before the clinical worsening of de Quervain tendinopathy;
Note: Examples of acute trauma include, but are not limited to, a laceration, puncture, heavy blow, fracture and crush injury.
- (8)being treated with or using growth hormone within the one year before the clinical worsening of de Quervain tendinopathy;
- (9)being treated with a fluoroquinolone antibiotic within the six months before the clinical worsening of de Quervain tendinopathy;
Note: Examples of fluoroquinolone antibiotics include, but are not limited to, ciprofloxacin, moxifloxacin, norfloxacin and ofloxacin.
- (10)being treated with an aromatase inhibitor within the one year before the clinical worsening of de Quervain tendinopathy;
Note: Examples of aromatase inhibitors include, but are not limited to, anastrozole, exemestane and letrozole.
- (11)inability to obtain appropriate clinical management for de Quervain tendinopathy;
Aggravation-only factors: the factors in subsections 8(6) to 8(11) apply only to material contribution to, or aggravation of, the condition where it was suffered or contracted before or during (but did not arise out of) the person’s relevant service.
