TRASK404 reports the case of a female child born at term by spontaneous delivery. Roentgenograms of the pelvis including the hip joints, made after delivery because of the presence of a small cutaneous depression at the level of the lumbosacral joint, revealed a slight outward and upward displacement of the right femur. The condition was apparently overlooked at the time of the examination, and no treatment was advised. One and a half years later the child had a complete dislocation of the right hip. There was no family history of congenital deformities. This case proves that congenital subluxation (or predislocation) of the hip may be present at birth and that the condition may be recognized by roentgenographic examination at this early date.
[Ed. Note.—This type of dislocation probably occurs during late fetal life.]
Ensthaler405 describes 2 cases of coxitis or osteomyelitis in newborn infants who had congenital dislocation
