Key legal question
Whether the cantonal court failed to sufficiently clarify the claimant's residual work capacity and neuropsychological limitations.
Extracted holding
The factual record was incomplete; further medical and vocational investigations were necessary.
Extracted reasoning
The orthopaedic report was limited to one specialty, while neuropsychological findings showed significant cognitive deficits and suggested only simple routine work, possibly only in a protected setting. The claimant's long employment with one accommodating employer did not reliably prove employability in the open labour market.
