Based upon a comprehensive review of the evidence, my observations of Claimant at hearing, and the application of Missouri Law, I find:
Occupational diseases are compensable injuries under Section 287.220.1 RSMo. Section 287.220.1 requires for SIF compensation, a claimant must have a preexisting permanent partial disability of such seriousness as to constitute a hindrance of obstacle to her employment and then sustain a subsequent compensable injury that results in additional permanent partial disability. The term "injury" as defined in Section 287.020.3(5) states:
The terms "injury" and personal injuries" shall mean violence to the physical structure of the body and to the personal property which is used to make up the physical structure of the body, such as artificial dentures, artificial limbs, glass eyes, eyeglasses and other prostheses which are placed in or on the body to replace the physical structure and such disease or infection as naturally results therefrom. These terms shall in no case except as specifically provided in this chapter be construed to include occupational disease in any form. [Emphasis added]
Section 287.067.3 states: An injury due to repetitive motion is recognized as an occupational disease for purposes of this chapter. An occupational disease due to repetitive motion is compensable only if the occupational exposure was the prevailing factor in causing both the resulting medical condition and disability. [Emphasis added]
Reading these statutory provisions together, I find Section 287.220.1 applies to injuries due to occupational diseases.
Claimant has established a right to recover from the Second Injury Fund. A claimant in a workers' compensation proceeding has the burden of proving all elements of his claim to a reasonable probability. Cardwell v. Treasurer of State of Missouri, 249 S.W.3d 902, 911 (Mo.App. E.D.2008). In order for a claimant to recover against the SIF, he must prove that he sustained a compensable injury, referred to as "the last injury," which resulted in permanent partial disability. Section 287.220.1 RSMo. A claimant must also prove that he had a preexisting permanent partial disability, whether from a compensable injury or otherwise, that: (1) existed at the time the last injury was sustained; (2) was of such seriousness as to constitute a hindrance or obstacle to his employment or reemployment should he become unemployed; and (3) equals a minimum of 50 weeks of compensation for injuries to the body as a whole or 15 % for major
extremities. Dunn v. Treasurer of State of Missouri as Custodian of Second Injury Fund, 272 S.W.3d 267, 272 (Mo.App. E.D.2008)(Citations omitted). In order for a claimant to be entitled to recover permanent partial disability benefits from the Second Injury Fund, he must prove that the last injury, combined with his pre-existing permanent partial disabilities, causes greater overall disability that the independent sum of the disabilities. Elrod v. Treasurer of Missouri as Custodian of the Second Injury Fund, 138 S.W.3d 714, 717-18 (Mo. Banc 2004). Claimant has met the burden imposed by law.
I find Claimant sustained 15\% PPD of the bilateral wrists as a result of the primary work related injury by occupational disease of December 1, 2005. Claimant settled her claim with Employer for that amount, and the evidence supports that level of disability. I further find Claimant had preexisting 22.5 % PPD of the Body as a whole referable to the low back as a result of her 2000 low back surgery. I find the primary work related injury combined synergistically with the preexisting injury, and a loading factor of 10 % should be added.
The SIF liability is calculated as follows: 15 % PPD of each wrist (52.5) weeks for
