Case Reports
Irreducible dislocations of the cervical spine with a prolapsed disc: preliminary results from a treatment technique.
The preliminary results from a treatment technique for irreducible dislocations of the cervical spine with prolapsed disk are reported. ⋯ The reported technique was used successfully in the treatment of four patients with irreducible dislocations of the cervical spine.

A 3-year prospective cohort study among 1334 workers was conducted. ⋯ High quantitative job demands and low coworker support are independent risk factors for neck pain. There are indications that another risk factor for neck pain is low decision authority.

Comparative Study
Biomechanical comparison of cervical spine interbody fusion cages.
An in vitro biomechanical study of cervical spine interbody fusion cages using a sheep model was conducted. ⋯ The biomechanical results indicate that design variations in screw and cylinder design groups are of little importance. In this study, however, cages with a cylinder design were able to control extension and bending more effectively than cages with a screw design.

Case report. ⋯ Post-traumatic syringomyelia has not been reported at so early a stage after injury. This disorder is an important clinical entity that must be recognized to prevent potentially fatal or devastating complications. As evidenced by the reported patient and the literature, if this disorder is discovered and treated early, permanent deficit can be avoided. The prevention of post-traumatic syringomyelia requires anatomic realignment and stabilization of the spine without stenosis, even in the case of complete injuries, to maintain the proper dynamics of cerebrospinal fluid flow.

The case of patient with scoliosis based on a rare hamartomatous, Proteus syndrome, is reported. ⋯ Scoliosis with Proteus syndrome seems to be based on hemihypertrophy, with no influence of mechanical stress.
