Questione giuridica chiave
Whether the insured was fully work-capable in an adapted job without left-arm strain.
Decisione estratta
Yes. In a suitable activity not loading the left arm, he was to be considered 100% capable of work.
Motivazione estratta
The contrary vocational assessment was not convincing in light of the medical evidence; a limitation can only exist for tasks still involving some left-arm load, not for work that does not use the arm at all.
