Theseright and left oblique diameters should be equal or nearly so. In obliquelycontracted pelves, as thesingle oblique pelvis ofNaegele, a considerabledifference may be such pelves severalother oblique measure-ments are of value, in orderto determine differencesbetween the two lateralhalves of the pelvis, al-though in these cases,more than in any other, anexternal examination isnecessary to detect the ex-act degree of deformit3^Three additional measure-ments are: (i) From theposterior superior spine ofone side to the tuber ischiiof the other. (2) From thespine of the last lumbarvertebra to the anteriorsuperior iliac spines of bothsides. (3) From the pos-terior superior s
