M-mode sonography of the caudal spinal cord in patients with meningomyelocele. Work in progress.

The authors prospectively studied movement patterns of the spinal cord in 46 patients (aged 0.5-16 years) with meningomyelocele but without major neurologic deficits. Three different motion patients were observed. Reduced mobility correlated with a higher risk of developing secondary tethered cord syndrome after a mean observation time of 15 months. This technique may be helpful in identifying patients for early surgery.
