Due to the characteristics of the two injury mechanisms the incidence has a double peak distribution with fractures related to major trauma occurring in the younger patients, while osteoporotic fractures occur commonly in the elderly. Odontoid fractures type II according to Anderson and d'Alonzo are typically related either to major trauma or osteoporotic bone quality. (4) The complication rate of nonsurgical treatment is similar to the complication rate of surgical treatment of odontoid fractures type II in the elderly. (3) Odontoid nonunion is not associated with worse clinical or functional results in the elderly. (2) Posterior atlantoaxial fusion for odontoid fractures type II in the elderly has the greatest bony union rate. (1) Surgical stabilisation of odontoid fractures type II improves survival in patients between 65 and 85 years of age compared to nonsurgical treatment. The systematic literature review came to the following conclusions. With regard to nonunion in 669 published cases primary posterior fusion had the best fusion results. A cumulative analysis of 1284 published cases found greater survival if elderly patients with odontoid fractures type II received surgical treatment (RR = 0.64). After a systematic literature research 38 publications were included. This systematic review focuses on the published results of type II odontoid fracture treatment in the elderly with regard to survival, nonunion, and complications. Still, due to the paucity of evidence the published treatment guidelines are far from equivocal. 2017.Odontoid fractures type II according to Anderson and d’Alonzo are not uncommon in the elderly patients.
