Before Decker, C.J., Moser, P.J., and Wedemeyer, J.
DECKER, C.J.
Shelby Mutual Insurance Company and the Village of West Milwaukee appeal from a judgment affirming an order of the Labor and Industry Review Commission (commission). The central issue on appeal is whether the trial court erred in affirming the commission's determination that repeated employment-related back injuries constituted an occupational disease so that a back injury sustained while the employe was at home on vacation became compensable under worker's compensation. We conclude that this determination is compatible with Wisconsin case law on occupational disease and accordingly affirm.
FACTS
From 1952 through 1976, William Mosser (Mosser) worked as a laborer for the Village of West Milwaukee (West Milwaukee). His duties included garbage collection and road repair work, which required heavy lifting and shoveling. He did not experience back problems before working for West Milwaukee.
Beginning in 1961, Mosser suffered repeated injuries to his lower back while performing his work duties for West Milwaukee. Due to these injuries, he often was forced to take time off from work, and several times he required medical treatment. He received worker's compensation benefits for several of the injuries. His last on-the-job injury to his lower back was in November, 1976. When Mosser returned to work after that injury, he worked through December 17, 1976, and then began a vacation.
*658 While at home during his vacation, Mosser was carrying a box weighing approximately ten or fifteen pounds when he sneezed. He immediately felt a sharp pain across his back, and sought medical treatment within a few days. He was unable to return to work. In April, 1977, a herniated disc was surgically removed from his lower back. In March, 1978, his doctor released him to perform light duty work, but West Milwaukee did not rehire him.
Mosser applied for worker's compensation benefits. Iowa National Mutual Insurance Company (Iowa National) provided worker's compensation insurance coverage to West Milwaukee until September, 1976, when Shelby Mutual Insurance Company (Shelby Mutual) assumed coverage. Following two hearings in 1978, the commission found that Mosser "sustained an injury arising out of his employment on an occupational basis," and that the date of injury was his last day of work, December 17, 1976. Mosser was awarded compensation for temporary total disability, thirty percent permanent partial disability, and medical expenses. Iowa National was dismissed from the suit because it was not the insurer on the date of injury.
West Milwaukee and Shelby Mutual petitioned the Labor and Industry Review Commission for review. The commission affirmed the examiners' findings and order. West Milwaukee and Shelby Mutual next appealed to the Milwaukee County Circuit Court, which affirmed the commission's order. West Milwaukee and Shelby Mutual then appealed to this court.
ISSUES
The following issues are raised on appeal:
(1) When an employe has a history of work-related trauma to his lower back, is a lower back injury sustained *659 while the employe was at home on vacation compensable as an occupational disease?;
(2) Is the commission's finding that Mosser suffered a thirty percent permanent partial disability supported by credible evidence in the record? and;
(3) Did the commission err in dismissing Iowa National and holding Shelby Mutual liable for the full amount of the award?
OCCUPATIONAL DISEASE
West Milwaukee and Shelby Mutual argue that Mosser's injury was noncompensable because it was an accident which did not occur while he was engaged in work-related activities. Their argument is in direct conflict with the commission's findings that the injury arose out of Mosser's employment and that his herniated disc and degenerative arthritis "were caused and aggravated beyond normal progression by his heavy work for [West Milwaukee]."
[1]
In essence, the appellants' central argument is that the commission erred in regarding Mosser's condition as an occupational disease. The commission's findings regarding the determination, cause, extent and duration of a disability are findings of fact, and are conclusive if supported by credible evidence. Transamerica Insurance Co. v. Department of Industry, Labor and Human Relations,
[2]
The question of the existence of an occupational disease is one of fact rather than law.[1] As such, the commission's determination is conclusive upon the court if supported by any credible evidence. Consolidated Papers v. Department of Industry, Labor & Human Relations,
The appellants also contend that the commission acted in excess of its powers, contrary to the judicial review provision, sec. 102.23 (1) (d), Stats., of the worker's compensation chapter, presumably on the ground that Wisconsin law does not recognize back injuries as an occupational disease.
The appellants cite South Side Roofing & Material Co. v. Industrial Commission,
*661 The issue in that case was whether the commission properly apportioned to three different employers partial liability for three different back injuries suffered over time by the employe. While the court there stated that "[t]his is not a case involving an occupational disease," id. at 408,
[3]
We have not discovered Wisconsin cases which explicitly permit or forbid repeated back injuries as being treated as occupational diseases for worker's compensation purposes. Our supreme court has always recognized the "natural and logical distinction" between occupational disease and industrial accident in worker's compensation legislation. Zabkowicz v. Industrial Commission,
*662 Early Wisconsin cases somewhat liberally construed occupational disease with respect to hernias, e.g., Marathon Paper Mills v. Industrial Commission,
An occupational disease, as that term is used in the act, is a disease like silicosis, which is acquired as the result and an incident of working in an industry over an extended period of time. The difference between an occupational disease and an affliction resulting from an accident is illustrated in hernia cases. Where hernia follows as a result of a definite accident the employee suffers an accidental hernia, as in Prentiss Wabers Prod. Co. v. Industrial Comm.
We believe this formulation allows repeated back injuries to be compensable as occupational disease. Our view is consistent with those of other states which have explicitly recognized repeated work-related back trauma as an occupational disease.[2]
[4]
Finally, we are persuaded that the facts satisfy the standards for recovery set forth in Lewellyn v. Department of Industry, Labor & Human Relations,
If the work activity precipitates, aggravates and accelerates beyond normal progression, a progressively deteriorating or degenerative condition, it is an accident causing injury or disease and the employee should recover even if there is no definite "breakage." [Citations omitted.]
The evidence was sufficient to show that this criterion was met. We reject appellants' argument that, because there was a "breakage" here, the third criterion is inapplicable. The language of that guide clearly allows for instances of "breakages" as well as the lack of them.
We affirm the determination that the repeated injuries Mosser suffered in the course of his employment constituted an occupational disease.[3]
PERCENTAGE OF DISABILITY
[5]
In Wisconsin, "any award for permanent partial disability [as to nonscheduled injuries] must be based upon some kind of a prediction as to the impairment of earning capacity." Butler v. Department of Industry, Labor & Human Relations,
INSURER'S LIABILITY
[6]
Shelby Mutual argues it should not be required to assume full responsibility for the worker's compensation award because no significant on-the-job trauma occurred while it was the insurer. "The Worker's Compensation Act does not provide for apportionment of liability for occupational disease as between . . . the successive insurers of a single employer whose employment caused the disease." Travelers Insurance Co. v. Department of Industry, Labor & Human Relations,
By the Court. Judgment affirmed.
NOTES
Notes
[] Petition to review denied.
[1] In Consolidated Papers v. ILHR Dept.,
[2] California, Fruehauf Corp. v. Workmen's Compensation Appeals Board,
[3] We note that the findings of the commission did not explicitly denominate Mosser's condition as an occupational disease. However, the commission assigned Mosser's last day of work as the date of injury. This is in keeping with sec. 102.01 (2) (f), Stats: "`Time of injury,' `occurrence of injury,' or `date of injury' means the date of the accident which caused the injury, or in the case of disease, the last day of work for the last employer whose employment caused disability,...." [Emphasis added.] Here, the sneeze which precipitated the disability occurred after Mosser's last day of work while he was on vacation. That the commission denominated the date as his last day of work clearly demonstrates that the compensation was for an occupational disease.
