The research that we have conducted for more than 30 years explains that there exists a traction force acting on the spinal cord in Chiari I Syndrome, due to an undetected malformation: tensed Film Terminale.
The tension caused by filum terminale besides causing the descent of the brain (Arnold Chiari type 1) and death of the central portion of the spinal cord (Syringomyelia) generates a bending stimulus on the spine in order to avoid the tension in the spinal cord and causes a deviation of the spine called Scoliosis.
The surgical sectioning of the filum terminale eliminates the root cause of these diseases and hence the progression of the above mentioned diseases comes to a halt.
Many patients suffering from Arnold Chiari I Syndrome with or without idiopathic Syrigomyelia and/or idiopathic Scoliosis have been operated at our center. The evolution of the disease was stopped and improvements in the symptoms have been noted, including some spectacular ones in some cases.
