was greatly improved. She had danced a little at the President's inaugural ball. She had entered the hospital in a wheel-chair and formerly was unable to walk without a cane. Dr. . W. Thorner: Last summer I learned that dislocation of the upper cervical vertebrae which is associated with acute symptoms of involvement of the cord is not necessarily fatal. The case was that of a man aged 40 who had suffered a trauma which was followed immediately by rigidity of the head on the neck and pyramidal tract signs. He refused hospitalization. In three weeks all signs and symptoms had disappeared. Dr. Robert Wigton : It has been interesting to hear of the other cases men¬ tioned. Clinically, this situation may be of more interest than is at first apparent. Dr. Gabriel Schwarz : I wish to point out that in the first case reported the type of dislocation is extremely rare. In the literature I could find no instance of dislocation of the occiput on the atlas that was not caused by trauma so severe as to be fatal. This patient is the only one who has survived.
