title: Erect lateral pelvimetry and the outcome of labor in Lagos.
abstract: The erect lateral radiograph pelvimetry measurements was related to the outcome of labor in 173 patients. The most common indication for pelvimetry was one previous caesarean section in 90 (52%) patients. Sixty-nine (39.9%) pelvimetry measurements were performed because of suspected cephalopelvic disproportion, while 20 (11.6%) were done because of breech presentation. In patients with a cephalic presentation at delivery, the mean +/- standard deviation (SD) obstetric conjugate for the 87 women who delivered vaginally (group 1) was 11.42 +/- 1.5 cm, while that of the 45 women who had emergency caesarean section (group 2) was 10.77 +/- 1.5 cm. The mean +/- SD anteroposterior outlet diameter for groups 1 and 2 were 12.24 +/- 1.9 cm and 11.84 +/- 1.7 cm respectively. Both differences were found to be statistically significant (p < 0.001 and p < 0.05 respectively). The mean +/- SD birthweight of the babies in groups 1 and 2 were 3.34 +/- 0.79 kg and 3.42 +/- 0.86 kg respectively. There was no statistically significant difference between the two groups (p < 0.05). The critical obstetric conjugate for safe vaginal delivery was 9.88 cm while the corresponding value for the anteroposterior pelvic outlet diameter was 10.24 cm.
