Key legal question
Whether the ankle bone lesions qualify as an occupational disease under accident insurance law.
Extracted holding
The occupational disease claim fails because a causal link to vibration exposure was not established with the required degree of probability.
Extracted reasoning
The evidence did not demonstrate, to at least a 50% probability, that work on vibrating platforms caused the bone lesions of the ankles; therefore the statutory requirements for an occupational disease were not met.
