Review Case ReportsHigh cervical disc herniation and Brown-Sequard syndrome. A case report and review of the literature.
We describe a rare herniation of the disc at the C2/C3 level in a 73-year-old woman. It caused hemicompression of the spinal cord and led to the Brown-Sequard syndrome. The condition was diagnosed clinically and by MRI six months after onset. Discectomy and fusion gave complete neurological resolution.

We tested the hypothesis that children who sustain a supracondylar fracture have a greater range of elbow hyperextension than those with a fracture of the distal radius. Three observers made 358 measurements in 183 children (114 boys and 69 girls). There were 119 fractures of the distal radius and 64 supracondylar fractures. ⋯ After allowing for age, gender and observer, there was no significant difference between the groups. Our study had greater than 80% power to detect a difference in hyperextension of 2 degrees at the 5% level with the above observer variability. When age and gender are taken into account, any variation in the amount of hyperextension at the elbow is not sufficient to explain the occurrence of a supracondylar fracture.
