Kernrechtsfrage
Whether the cantonal court based its decision on an incomplete medical record by ignoring the left cubital neuropathy and its impact on work capacity.
Extrahierter Entscheid
Yes. The court could not disregard the elbow problem and the post-operative course; further instruction was necessary.
Extrahierte Begründung
The expert and later reports raised serious doubts about the benign character of the left-arm condition. The cantonal court relied on a pre-operative prognosis without verifying whether the expected recovery had occurred, contrary to its duty to establish the facts fully.
