translate English to French: For more than 30 years, our research explains that there is a downward movement of the spinal cord in Chiari I malformation, due to a malformation not detected: tight filum terminale is responsible for the same symptoms of Chiari II and Chiari III malformations; it pulls the spinal cord into the vertebral canal. The spinal cord and the spine have both the same length upon the fifth month of embryonic life, from this point to adulthood, the spine will grow up to twenty more centimeters.
Pour la malformation de Chiari II et III, l’explication réside dans la traction vers le bas que subit la moelle épinière pour être fixée par d’autres malformations de la colonne vertébrale comme le myéloméningocèle ou autres.
