Imaging findings of flexion type of hangman's fracture; an attempt for a more objective evaluation with newly introduced scoring system.

Objective: To identify the flexion type of hangman's fracture on imaging studies.

Methods: 38 cases of hangman's fracture were retrospectively studied and categorized into flexion and non-flexion groups. Plain radiograph, CT and MRI of these patients were evaluated; 13 radiological parameters that might define flexion injuries were measured.
