Key legal question
Whether post-30 April 2010 back complaints were naturally caused by the accident or by a worsening of a pre-existing spinal condition.
Extracted holding
The lumbar and thoracic complaints were not shown with predominant probability to be accident-caused, nor as a worsening of the pre-existing condition.
Extracted reasoning
Imaging showed pre-existing pathological changes, including scoliosis and Scheuermann disease, without accident-specific lesions. A symptom-free interval of about four months and the contemporaneous records supported a non-traumatic explanation.
