C. V. Mosby Co. 1915._ The general course of labor is modified by pelvic contractions in various ways. 1—Abnormal presentations are three or four times commoner in contracted than in normal pelves. 2—Prolapse of the cord is much commoner than in normal pelves. 3—When natural delivery occurs labor is prolonged and the mechanism is modified. 4—Unless the true conjugate is at least 3¼ inches, even with artificial aid the survival of the child is seriously jeopardized. 5—The maternal risks are increased by the greater length and difficulty of the labor and by the frequent necessity of employing artificial methods of delivery. 6—The fetal risks are increased in natural delivery by severe compression of the head during its passage through the narrow pelvis, and other circumstances by the operations required to effect delivery, some of which involve the destruction of the fetus.

Edited by Reuben Peterson, A.B., M.D. Lea Bros. & Co., Phil. and New York. 1907._ Labor complicated by anomalies of the Bony Pelvis. John F. Moran, M.D. The frequency with which pelvic contraction occurs can only be determined with relative accuracy. There is in existence a comparatively large amount of statistical data on this subject, but the reports of different investigators vary within wide limits, and these variations are naturally not to be explained entirely on the assumption of racial conditions, or geographic distribution. Between these wide limits are arrayed the figures of about 20 modern observers in different parts of the civilized world who have reported statistics of cases. The combined figures of 19 observers include a total of over 150,000 cases examined for pelvic contraction. In these cases the average of contraction is found to be about 10%. Williams concludes that contracted pelves occur in from 7% to 8% of the white women of this country. P. 658–659.
