Endemic cretinism in the adult is often accompanied by a variety of skeletal malformations. The victims of this disorder characteristically exhibit poor posture, with the head inclined forward and with the hips, knees and ankles maintained in partial flexion.1 Their gait is such as to give the observer an impression of marked instability. One of the factors contributing to the instability is the disturbance of the mechanics of pelvic support resulting from relaxation of the pelvitrochanteric musculature. This in turn arises from the presence of coxa vara, a deformity which is frequently encountered in cretins.2
The osseous changes appearing in children and resulting in the development of coxa vara in cretins have received scant attention. But few reports on the subject have appeared and these have been limited to the Swiss and German literature. In them the authors have described the occurrence of a disease of the hip
