Kernrechtsfrage
Whether the medical assessment of residual work capacity was unreliable and required further evidence.
Extrahierter Entscheid
The regional physician's profile was coherent, based on examination and case history, and sufficiently consistent with the other medical reports; further inquiries were unnecessary.
Extrahierte Begründung
The court accepted the lower court's assessment that the dominant right hand remained usable for light and medium work within the stated limits. The claimant's own view of greater incapacity was unsupported by the file, and there was no medically confirmed 'claw hand' or complete loss of gripping ability.
