An experimental study of traction on the cervical spinal nerves

The authors present a study of experimental traction on 48 cervical spinal nerves obtained from fresh cadavers. 16 avulsions of the roots were produced, always after rupture of the dura mater. The different stages of traction and rupture are described, as well as the different specimens after rupture. Ways of protecting the spinal nerves against avulsion are discussed.
