The authors illustrate the results of a series of 47 fractures of the odontoid process all treated according to two non-surgical methods, among the most diffused and accepted: Minerva plaster and halo-plaster. The various elements used to classify odontoid fractures are examined, as is their importance for prognosis. The conclusions refer to two essential points: 1) fractures with a higher risk of nonunion are Anderson type II, with posterior shifting, in elderly patients; 2) reduction and immobilization with a halo-plaster may be considered the first choice of a method for most of these fractures, in consideration of the limited risk of nonunion involved.
