Multiple Fractures of the Axis

Multiple fractures of the axis are not common lesions. A retrospective study was performed to identify the different fracture patterns and to analyze the incidence of these injuries and their long-term behavior. The medical records of 674 consecutive patients with fractures of the cervical spine were reviewed. Nine (1%) of 674 patients (6 men and 3 women) had multiple fractures of the axis. Mean patient age was 48 years. The most common lesion was a combination of traumatic spondylolisthesis with either an odontoid process or a teardrop fracture of the axis body. All patients were treated conservatively with an excellent or good outcome at mean 12-year follow-up (range: 2-18 years). Computed tomography was the imaging modality of choice for the correct diagnosis of these rare lesions.
