Treatment of lower cervical spinal injuries--C3 to C7. 
Injuries of the lower cervical spine are categorized according to the morbid anatomy of the lesion.  Most often, such injuries are successfully treated by surgery through a posterior approach.  After anatomic restoration, internal fixation with plates and screws provides for stability and arthrodesis.  Of 221 cases of lower cervical spine injuries, posterior stabilization was accomplished in 89%.  There was no secondary displacement in 85% of cases.
