Key legal question
Whether the chronic painful residual condition in the left lower leg was in a natural causal link with the 1998 accident.
Extracted holding
The file did not permit a reliable denial of causation; further factual investigation was required because the accident and early records left open whether the left leg had been injured.
Extracted reasoning
The absence of an explicit mention of leg injury in early hospital records did not exclude such an injury, especially since the shoulder trauma was the treatment focus. A note in the former GP record and the police report indicated left-leg involvement, no prior leg complaints were shown, and the lower-court assessment failed to order additional inquiries despite unresolved contradictions.
