Anterior Interbody Fusion through the Retropharyngeal Approach for Hangman's Fracture: Report of 2 Cases

Most patients with hangman's fracture frequently responded to consertvative therapy consisted of skeletal traction and halo vest, and surgery to stabilize or reduce further injury is seldom necessary. But occasionally operative stabilization may be necessary and can be achiveed satisfactorilly through anterior or posterior approach. Anterior interbody fusion at the G2-3 interspace has advantages of immediate bony stabilization with preservation of rotatory motion compared with posterior approach.
