1. In the generally contracted pelves, all of the external measurements are shorter than normal, the diagonal conjugate being 11.5 cm., or less. In simple flat pelves, on the other hand, the external measurements are normal, but the diagonal conjugate is 11 cm., or less.
If the distance between the tuber-ischii is only 8 cm., or less, the patient has some kind of a funnel pelvis; simple, if the inlet measurements are normal, but if they also are shortened, the pelvis is described as a generally contracted funnel.
The rachitic pelves present certain characteristic features, one being less difference between the inter-spinous and inter-crestal measurements than is found in a normal pelvis. Another, that the distance between the tuber-ischii is always of normal length and may even be greater than normal. The peculiar deformity of the sacrum, however, is the most characteristic abnormality of the rachitic pelves. The concavity from above downward is markedly increased, in some cases almost forming an angle, while the horizontal concavity is nearly or quite obliterated. The commonest type of a rachitic pelvis is one in which all of the inlet measurements are shortened, the inter-tuberous distance normal, and the sacrum characteristically deformed. This is called the generally contracted, rachitic pelvis. In the flat rachitic pelvis all of the inlet measurements are normal, except the diagonal conjugate, which may be shortened to 11 cm., or less, and the sacrum presents the deformity described above.
