[Considerations on various spinal pains].

Any nerve root irritation from about T6 to L1 is able to carry about parietal and visceral pain in the abdomen, owing to the metameric distribution of the splanchnic and somatic afferent ways along the dorsal roots at all these levels. The cause of abdominal segmental neuralgia are numerous. Radicular abdominalgia is a syndrome of painful and paresthetic sensations, which involve both somatic and visceral components of one or more segments, according to the metameric law. In the osteo-arthrosis in the dorsal intervertebral joints is a most common cause of radicular syndromes simulating intra-abdominal surgical conditions.
