Thiscondition is known as spondylolithesis, (Fig. 128.) 372 LABOR. The effect of this is sufficiently obvious, for the projection of thelumbar vertebrae prevents the passage of the child. To such an extentis obstruction thus produced, that, in the majority of the recordedcases, the Cesarean section was necessary.
