Questione giuridica chiave
Whether the claimant was entitled to an invalidity insurance pension after the second accident worsened her condition.
Decisione estratta
The second accident did not cause an invalidity-relevant deterioration or greater work incapacity; pension entitlement was therefore denied.
Motivazione estratta
The Federal Court accepted the cantonal findings based on the medical record, especially the rehabilitation clinic and RAD reports, and held that no obvious factual error or legal error was shown. The existing arm-related impairment alone did not justify a pension, and the later accident did not increase the invalidity degree beyond the already final assessment.
