[Conservative treatment of trauma-associated fractures of the cervical spine with orthoses-A review].

Stable C2 dens fractures without relevant clinical restrictions allow conservative treatment in a rigid cervical orthosis under radiological monitoring every 1-4 weeks. Type II fractures require special attention due to the risk of instability. Hangman's fractures can be safely treated in rigid cervical orthoses. The current state of knowledge does not allow any recommendation for conservative treatment of Hangman's fractures with orthoses. Stable vertebral body fractures without involvement of the spinal canal can also be treated conservatively with orthotic devices. Randomized controlled studies are required to develop a secure state of evidence and are currently not available.
