Kernrechtsfrage
Whether the accident remained a natural causal factor for ongoing back complaints after 2008-12-31
Extrahierter Entscheid
The accident caused only a temporary worsening of pre-existing degenerative spinal conditions; causal significance ended by the relevant date.
Extrahierte Begründung
Medical records showed only a contusion and no structural lesion attributable to the fall. Pre-existing degenerative back problems were documented, and the medical evidence supported that any traumatic aggravation had resolved. The court also relied on the ordinary medical experience that such aggravations usually end within months, and the claimant offered no persuasive contrary evidence.
