An unusual Hangman's fracture: description and surgical management.

C2 pedicles, or "Hangman's" fracture and "Tear-Drop" fracture, have until now been described as two distinct entities, the former caused by extension-distraction and the latter by compression-flexion mechanisms. The present clinical case combined these two fracture types of the second cervical vertebra (C2), without neurologic complication. Surgical management reduced and stabilized the lesions of the bone and of the mobile segment between C2 and C3. A right-side subhyoid presternocleidomastoid approach was selected, the main deformity lying between the body of the second and third cervical vertebrae.
