Open reduction and C1C3 posterior Harms-Goel fixation for unstable Hangman’s fracture: technical note

Hangman’s fracture occurs in the elderly following low kinetic energy fall from their height, or in the young during traffic accident. Classically described as bipedicular C2 fracture, Hangman’s fracture results from oblique hyperextension-flexion vector forces which can lead to anterior dislocation of C1C2 complex over C3 vertebral body in case of associated damage to C2C3 disc and ligaments. Even though most cases of Hangman’s fracture are not displaced (grade 1) and can be managed with orthopaedic treatment using cervical brace, highly displaced cases of Hangman’s fractures (some grade 2, all grade 3) require surgical stabilization. Given the limited capabilities of reduction and the odds for mechanical failure of anterior C2C3 discectomy and fusion, we provide a reproducible method using a specific rod persuader on C1 screws aiming to realign and stabilize displaced cases of Hangman fracture using the C1C3 “Harms-Goel” procedure.
