There is no dispute that Zemir Harbas, Employee herein, sustained injuries to both shins as a result of the November 21, 2004 work-related accident. Employee also claims that he sustained injuries to his back, knees, teeth and depression as a result of the foregoing work-related accident. Employer denies that Employee sustained any injuries to his knees or teeth and that Employee developed depression as a result of the work-related accident.
The employee must establish a causal connection between the accident and the claimed injuries. Davies v. Carter Carburetor Div., 429 S.W.2d 738 (Mo. 1968); McGrath v. Satellite Sprinkler Systems, 877 S.W.2d 704, 708 (Mo. App. 1994); Blankenship v. Columbia Sportswear, 875 S.W.2d 937, 942 (Mo. App. 1994); Fisher v. Archdiocese of St. Louis, 793 S.W.2d 195, 198 (Mo. App. 1990); Cox v. General Motors Corp., 691 S.W.2d 294 (Mo. App. 1985); Griggs v. A.B. Chance Company, 503 S.W.2d 697, 703 (Mo. App. 1974); Smith v. Terminal Transfer Company, 372 S.W.2d 659, 664 (Mo. App. 1963).
Amendments made to Section 287.020.2 Mo. Rev. Stat. (2000) in 1993 require that the injury be "clearly work related" for it to be compensable. An injury is clearly work related "if work was a substantial factor in the cause of the resulting medical condition or disability. An injury is not compensable merely because work was a triggering or precipitating factor." The Supreme Court held in Kasl v. Bristol Care, Inc., 984 S.W.2d 852 (Mo. 1999) that the foregoing language overruled the holdings in Wynn v. Navajo Freight Lines, Inc., 654 S.W.2d 87 (Mo. 1983), Bone v. Daniel Hamm Drayage Company, 449 S.W.2d 169 (Mo. 1970), and many other cases which had allowed an injury to be compensable so long as it was "triggered or precipitated" by work. Injuries which are triggered or precipitated by
work may nevertheless be compensable if the work is found to be a "substantial factor" in causing the injury. Kasl, supra at 853. A substantial factor does not have to be the primary or most significant causative factor. Bloss v. Plastic Enterprises, 32 S.W.3d 666, 671 (Mo. App. 2000); Cahall v. Cahall, 963 S.W.2d 368, 372 (Mo. App. 1998). An accident may be both a triggering event and a substantial factor in causing an injury. Id. Subsection 2 also provides that an injury must be incidental and not independent of employment relationship and that "ordinary, gradual deterioration or progressive degeneration of the body caused by aging" is not compensable unless it "follows as an incident of employment." The extent to which the 1993 amendments have further modified prior caselaw will be determined by the appellate courts. See Cahall, supra at 372 .
The quantum of proof is reasonable probability. Davies, supra at 749; Downing v. Willamette Industries, Inc., 895 S.W.2d 650, 655 (Mo. App. 1995); White v. Henderson Implement Co., 879 S.W.2d 575, 577 (Mo. App. 1994); Fischer at 199; Banner Iron Works v. Mordis, 664 S.W.2d 770, 773 (Mo. App. 1983); Griggs at 703.
