![]() The current literature suggests that well-selected patients >60 years of age undergoing surgical treatment for a type II odontoid fracture have a decreased risk of short-term and long-term mortality without an increase in the risk of complications. Similarly, no difference in mortality or complication rate was identified with hard collar or a halo orthosis immobilization. This is the least common type of odontoid fracture and is generally stable. Type 1, Oblique fracture through the odontoid tip, Stable Type 2, Fracture through the base of the dens, Unstable. This fracture is therefore described as an oblique avulsion fracture of the tip of odontoid resulting from avulsion of the alar ligament. This is the point of insertion for the alar ligaments. Surgical approach (posterior vs anterior) showed no significant difference in mortality or complication rate. A type I odontoid fracture involves the tip of the dens. Short-term mortality (odds ratio, 0.43 95% confidence interval, 0.30-0.63) and long-term mortality (odds ratio, 0.47 95% confidence interval, 0.34-0.64) were lower in patients who underwent surgical treatment than in those who had nonsurgical treatment, and there were no significant differences in the rate of complications (odds ratio, 1.01 95% confidence interval, 0.63-1.63). An analysis of short-term mortality, long-term mortality, and the occurrence of complications was performed.Ī total of 452 articles were identified, of which 21 articles with 1233 patients met the inclusion criteria. Most authors consider this lesion to be stable, although the mechanism(s) of injury has not. We performed a systematic review of literature published between January 1, 2000, and February 1, 2015, related to the treatment of type II odontoid fractures in patients >60 years of age. Only four cases of Type I odontoid fracture have been previously described in the English literature. Higher risk of nonunion with comminuted fracture, age > 50 or more than 5mm displacement. To compare the short-term (60 years of age with a type II odontoid fracture managed either operatively or nonoperatively. Oblique fracture through the odontoid tip. Odontoid fractures are the most common cervical spine fracture in the geriatric population however, the treatment of type II odontoid fractures in this age group is controversial.
