[Myelography--what is it really worth?].

The routinelike employment of myelography is attached and as follows established. 1. Primum non nocere! This old medical axiom also here has its validity, there are enough examples of incidents and late damages in employment of this method. 2. The myelography is not reliable. Errors are described. 3. Superfluous painful examinations should be spared for the patient: operation and myelography are two interventions. 4. The myelography costs time and prolongs staying in hospital.
