Questione giuridica chiave
Whether the insured is entitled to a disability pension higher than 23%
Decisione estratta
The record was insufficient to decide the degree of incapacity; further clarification was needed, especially on whether left-sided sciatic pain is accident-related and affects the work-capacity profile.
Motivazione estratta
The medical opinions did not sufficiently establish causality of the lumbar complaints. The MEDAS report did not show time limitation due to the shoulder and knee injuries alone; the unresolved causal link to the sciatica could affect the earning-capacity assessment.
