Key legal question
Whether the insurer remained liable for left-forearm complaints beyond 2009-04-30
Extracted holding
No; the later complaints were no longer shown with sufficient probability to be caused by the accident of 2009-01-06.
Extracted reasoning
The court relied on the persuasive medical assessment that the MRI showed no traumatic findings and that the later de Quervain tenosynovitis was a new or idiopathic condition, while further evidence would not add relevant findings.
