Abstract
1. Sixty myelographs have been obtained in severe traction injuries of the brachial plexus.
2. Seventy-eight traumatic meningoceles were outlined.
3. Multiple meningoceles indicate a gloomy prognosis.
4. In forty patients the results were compared with those obtained with the "axon reflex."
5. Myelography is a valuable aid in obtaining an early prognosis but the results must be correlated with the clinical picture.
