An Atypical Hangman’s Fracture with Atlantoaxial Instability Managed by C1-C2 Arthrodesis: A Case Illustration

Abstract

Atypical hangman’s fractures (AHFs) are asymmetrical axis body fractures. These fractures tend to be unstable. We came across a case of AHF involving the left half of the axis body and contralateral lamina. The left C1-C2 joint was dislocated, but bilateral C2-C3 joints were stable. We performed C1-C2 stabilization and fracture alignment with the Goel–Harms technique.
