Kernrechtsfrage
Whether the insured person's work capacity loss from the 1999 accident was correctly assessed for invalidity pension purposes.
Extrahierter Entscheid
The medical file was insufficient to quantify the accident-related work incapacity; a new expert assessment is required before deciding the pension claim anew.
Extrahierte Begründung
The orthopedic report was internally contradictory and mixed medical incapacity with invalidity assessment. The MEDAS report assessed overall incapacity without separating accident-related shoulder effects from non-accident-related degenerative conditions, so it could not support a precise pension calculation.
