Questão jurídica principal
Whether the accident caused or durably aggravated the pre-existing spinal condition and disc herniation
Decisão extraída
No durable accident-related aggravation was shown; the disc herniation was not plausibly causally linked to the accident.
Fundamentação extraída
A lasting aggravation of a pre-existing spinal disease requires radiographic evidence of a rapid decrease in disc height after the trauma and the appearance or enlargement of marginal osteophytes. Those indicia were not established here.
