This is a clinical analysis of 244 obstetrical patients who received X-ray pelvimetry among a total of 3655 patients admitted to the Dept. of Ob & Gyn from January 1, 1965 to August 31, 1968.
The Colcher-Sussman technique was used to measure the various´ diameters of the pelvis while the biperietal diameters and weights were obtained postpartum.
Since laborr and delivery are a dynamic process this study is mainly concerned with relatioiish-ips between pelvic diameters and fetal weight-size factors.
1. 190 X-ray were taken in patients thought to have dystocia with a vertex presenting. In.. this 54.2% had a vaginal delivery, 12.2% had a mid-forceps delivery and the remaining 33.3% received a Cesarean section.
2. In this same group when the AP of the inlet was less than 10.0cm.61.9% had a Cesarean. section, when between 10.0 and 10.4cm. the rate was 30.2% and above 10.5 the rate was22.5%.
3. Even better correlation is found in terms of type of delivery when the A-P of the inlet, is related to the biparietal diameter of the infant. When the difference was between 1.0 and 1.4cm. the C-section rats was 51.1%; when the difference was between 1.5 and 1.9, cm. the C-section rate was 20.7% and above 2.0cm. the rate was 14.5%. With the birth. weight above 3500gm. and the difference under 1.4cm. the C-section rate was around 73%..
4. The mid-pelvic transverse diameter was much less accurate in predicting the method of delivery, especially C-section.
5. When used with nulliparous breech presentation the section rate was 12.5%.
6. When the X-ray was used in patients requiring an induction the subsequent section rate was 7.9%.
