High cervical spine and craniocervical junction injuries in fatal traffic accidents: a radiological study.

Postmortem radiographic examinations in 312 victims of fatal traffic accidents were analyzed with respect to injuries to the cervical spine. Most fractures and dislocations in this group were found to involve the craniocervical junction and the upper two cervical segments. Over half were flexion injuries, one-fifth caused predominantly by extension. Flexion and extension views were found to be helpful in demonstrating the instability of many injuries.

Atlanto-occipital hypermobility.

Hypermobility of the atlanto-occipital joint can be seen following trauma or in a patient with congenital fusion of C1-C2 as a progressive problem. The lateral roentgenogram is the key to the diagnosis, and familiarity with the normal anatomy is necessary. In the trauma setting care should be taken not to increase the dislocation with traction. Treatment by a posterior craniocervical fusion has proved successful in both groups of patients.

[Variants of congenital hypoplasia of the arches of the upper cervical vertebrae and their clinical significance].

A clinico-roentgenological examination of the transitional craniovertebral division has revealed a high incidence and a great diversity of isolated underdevelopment of the arches of the upper cervical vertebra--from their fissure-like splitting to complete absence. Usually these forms create no preconditions for disturbances of any functions, do not manifest clinically, and can be regarded as variants of normal structure of the craniovertebral division.

[Trans-oral approach. Technique and indications].

The trans-oral approach is a well codified and classical technique in neurosurgery. When correctly performed, this procedure gives excellent results in selected indications, such as: mechanical decompression of ondotoïdal vicious callus and more particularly, malformations of the craniovertebral function. This approach is also used for extirpation of C1, C2 and inferior clivus tumors. The complications of this technique are mainly septic, and must be prevented by appropriate pre and post-operative nursing.
