Reduction of displaced Hangman's fracture by compression across crossed translaminar screws.

Hangman's fractures are fractures across the pars interarticularis of C2 with possible subluxation of C2 on C3. However, no criteria have been defined for the specific indications for surgical fixation. We describe a 30-year old man who sustained a displaced Hangman's fracture after a motor vehicle accident. The fracture was successfully reduced, in the operating room, by compression across crossed translaminar screws while lifting C1 relative to C2. Intra-operative reduction of a displaced Hangman's fracture by compression across crossed translaminar screws is safe and technically feasible.
