Pre-existing osteoporosis did not break causal link to spinal fracturesGenerato dall'IA

LAA art. 6; natural causation and pre-existing condition; evidentiary value of medical expertise. Where expert evidence establishes that a pre-existing osteoporosis could not have caused vertebral fractures, the accident remains the natural cause of the harm despite the underlying vulnerability. A pre-existing state does not interrupt causation merely because it made the insured more susceptible to injury; decisive is whether the accident is still a relevant cause of the disability (consid. unspecified). Entitlement to accident benefits, including a disability pension, follows if the accident-related sequelae are shown to be causally responsible for the incapacity to earn.
