\*Small pelvis\* *(additional large pelvis)* *—a pelvis in which there are two or more pubic branches and common sciatic branches.*

Small basins are divided into four degrees:

1. The right and left sides of the nameless ribs form a symmetrical concavity, divided by the bend of the sacrum into a convex upper and saddle-shaped lower part. (posterior to the concavity is a shallow additional pelvic fossa).

2. The ribs that form the concavity of the lower part of the pelvis are non-pubic.
