Question juridique clé
Whether the back complaints since March 2003 are in natural and adequate causal connection with the 31 May 1991 accident.
Solution extraite
The causal link is established; the accident and resulting transfemoral amputation are an indirect partial cause of the back complaints.
Motifs extraits
The expert opinion, based on additional imaging, renewed examination, literature review, and external expert validation, convincingly showed that back pain after lower-limb amputation, especially transfemoral amputation, is a recognized and clinically relevant phenomenon. The fact that another cause may have triggered the onset of symptoms in 2003 does not exclude accident-related partial causation.
