I am hoping to find someone who knows where I may find some information on Arnold Chiari Malformation. I have searched the internet, and it seems that most of the reading is too vague, not very in depth. For example, they talk about surgical correction, but don't mention at what mm of herniation. Very little is discussed about outcomes, care given to pt's, risks, or success rates, etc. I would really like to find a resource for these questions. Can anyone help?
