![]() ![]() One study of 17 patients suggests odontoid fractures are an infrequent cause of SCI with ND, most often occurring in males with congenital stenosis sustaining high-injuries. However, there is less literature examining patients with ND. Previous studies of patients with Type II odontoid fractures but without ND suggest these injuries are associated with a mortality rate of 12.8% and a major complication rate of 47.8% after a minimum followup of 0 day (average, 15.1 days range, 0–161 days). However, this is a rare event with an occurrence rate ranging from 3% to 25% attributable in large part to the capacious spinal canal at this region. Substantial displacement of the fractured segment may result in cord compression resulting in spinal cord injury (SCI) with possible neurological deficits (ND). Originally described by Anderson and D’Alanzo, Type II fractures occur at the junction between the body of the axis and the odontoid process. Īpproximately 10% to 20% of all cervical fractures occur at the odontoid process, and the majority of these are classified as Type II fractures. Compounding the problem is the increasing number of comorbidities in the elderly population. The elderly are particularly predisposed to bony injury as a result of a greater predilection for sustaining low-energy fall injuries coupled with an increased incidence of osteopenia. Cervical fractures are some of the most frequent spinal injuries in the elderly population today, accounting for 25,000 new hospitalizations every year in the United States. ![]()
