"Liability of the Second Injury Fund is triggered only 'by a finding of the presence of an actual and measurable disability at the time the work injury is sustained.'" E.W. v. Kansas City School District, 89 S.W.3d 527, 537 (Mo. App. 2002) (citation omitted). To implicate the Second Injury Fund, the employee must have an actual and measurable
preexisting disability at the time the work injury is sustained of such seriousness as to constitute a hindrance or obstacle to employment. Section 287.220.1 RSMo.
[T]he proper focus of the inquiry as to the nature of the prior disability is not on the extent to which the condition has caused difficulty in the past, it is on the potential that the condition may combine with a work-related injury in the future so as to cause a greater degree of disability than would have resulted in the absence of the condition."
Loven v. Greene County, 63 S.W.3d 278, 287 (Mo. App. 2001).
We have found that employee suffered from preexisting permanent partial disabilities amounting to 25 % of the body as a whole referable to the lumbar spine, 25 % of the body as a whole referable to the cervical spine, 50 % of the right shoulder, 35 % of the left shoulder, 25 % of the right hand, and 15 % of the right knee. The medical records reveal ongoing treatment spanning many years for certain of these conditions, such as the lumbar and cervical spine syndromes. The medical records also contain numerous preexisting work restrictions as well as suggestions from employee's doctors that he change the type of work he was performing (for example, Dr. Orell's suggestion on July 10, 1990, that employee change his work schedule due to the impact of overhead work on his right shoulder condition). Given the credible opinions of Ms. Gonzalez and the clear potential-demonstrated by both the treatment record and employee's testimonyfor each of employee's preexisting conditions of ill to combine with later injuries to create greater disability than would result in their absence, we conclude that each of these conditions were hindrances or obstacles to employment as of May 20, 2006.
Given the foregoing, we conclude that employee has met his burden of proving the presence of actual and measurable disabilities of such seriousness as to constitute hindrances or obstacles to employment at the time the work injury was sustained.
