Kernrechtsfrage
Whether the insured suffered an accident within the meaning of Art. 4 ATSG
Extrahierter Entscheid
The alleged event was not proven with sufficient probability; the injury could also have arisen solely from disease-related causes.
Extrahierte Begründung
The insured could not reliably describe how the injury occurred. The medical records contained only anamnesis, not a confirmed traumatic cause. Given the diabetic condition and the possibility of spontaneous ulceration, an external factor had to be established, which was not possible.
