Atlanto-axial rotatory fixation is often seen in childhood. We experienced two difficult cases of children's atlanto-axial rotatory fixation.
The first case was a 9-year-old girl who developed torticollis after experiencing pain in the right side of her neck and a fever. 3 months later, she visited our hospital and was admitted. CT scan revealed atlanto-axial rotatory fixation.
She was put on neck traction for 3 weeks (Grisson type), but reduction was not complete. The treatment was therefor change to skull traction. Her deformity was corrected. However torticollis recurred, and she was put on Halo-vest for 3 months.
The second case was a 6-year-old girl who had been treated with Juvenile Rheumatoid Arthritis since she was 5. She generally developed neck pain. Subsequently trismus and torticollis appeared before 3 months before she visited our hospital. Atlanto-axial rotatory fixation was confirmed in CT scan and plain radiograph. Torticollis was corrected easily by skull traction, but deformity recurred soon after. Neck deformity improved by increasing aspirin dosage, however torticollis remained slightly.
