Fused atlantic posterior arch hypoplasia - rachischisis? (59/92)

Bony fusion between the skull and the vertebral column is a sufficiently rare skeletal anomaly that we may never have the opportunity to see it during our career. An 'evidential' discovery led to an example being made available for detailed study. This illustrated paper presents the findings of the study, reviews other studies, and discusses the genetic origins of such an outcome.  (+info)

Traumatic atlanto-occipital dislocation: a case report. (64/92)

We report a 30-year-old man with atlanto-occipital dislocation after a traffic accident. Diagnosis was based on radiography, computed tomography, and magnetic resonance imaging. Owing to the critical conditions that did not fulfil advanced trauma and life support protocols, surgical treatment was deferred, and the patient died 10 hours later.  (+info)
