To the Editor.—In the August 1967 issue, a case is reported of the Ellis-Van Creveld syndrome well documented by Drs. Gellis and Feingold.
The pelvis, as shown in the radiograph, shows clearly an anomaly which H. J. Kaufmann (The Pelvis in the Ellis-Van Creveld Syndrome, Ann Radiol, out of series number 8, p 146, 1965) has pointed out: an indentation of the acetabulum, giving the aspect "en trident" of the roof of the acetabulum. This formation is reversible as the patient grows.
It is also seen in other conditions described by my colleague, Professor Jeune of Lyons: The two conditions have certain features in common (Monnet, M.P., and Monnet, F.: Le syndrome d'Ellis-Van Creveld, Rev Lyon Med16:47, 1967), especially the "thorax en guêpe" or hemithoracic constriction which is clearly seen in your good picture.
