Key legal question
Whether the insured proved a worsening of health justifying a higher disability rate after the 2010 decision.
Extracted holding
No durable worsening of the left-foot condition was established; the medical report relied on did not show a relevant aggravation of work capacity limitations.
Extracted reasoning
The cited medical statement concerned causation with the July 2011 accident, not a sustained deterioration of the underlying lesions or their impact on residual work capacity.
