“…There are few studies in the literature that analyze normal pelvic diameters in the general population (Lenhard et al, 2010), as most of these are determined in pregnant women during labor (Daghighi et al;Harper et al;HuertaEnochian et al;Korhonen et al, 2010;Lenhard et al, 2009;Spörri et al, 1997Spörri et al, , 2002. More importantly, no study has established a difference in these parameters regarding age.…”

“…This clinical pelvimetry has been reported to have limited value in identifying women at risk of dystocia (Rozenholc et al) and is prone to subjectivity (Tita), reason why a more objective and reliable method is needed (Lenhard et al, 2009(Lenhard et al, , 2010. Different imaging studies have been used for pelvimetry to identify the small pelvic diameters, examples include: ultrasound (Daghighi et al, 2013), X rays (Harper et al, 2013;Korhonen et al, 2014), computed tomography (CT) (Lenhard et al, 2009(Lenhard et al, , 2010 and magnetic resonance (Huerta-Enochian et al, 2006;Korhonen et al, 2014;Spörri et al, 2002). CT has been described as the study with the most accurate and reliable picture for high quality pelvimetry (Herrmann et al, 1990;Lenhard et al, 2009Lenhard et al, , 2010.…”

SUMMARY:The Mexican government passed a new reform of article 11 of the General Law in 2014 regarding Women's Access to a Life Free of Violence, which states that a cesarean section may not be performed if a vaginal birth is viable. Cesarean sections are excessively indicated in Northen Mexico, using the diagnosis of cephalopelvic disproportion due to a narrow pelvis. Currently, there is no standardized morphometry of the female pelvis in a Mexican population to establish adequate diagnostic parameter. Our study measures the pelvic diameters of the birth canal using abdominopelvic computed tomography (CT). Two hundred and ninety CT from Mexican women between the ages of 18 and 50 were collected and 3D reformatted in order to morphologically measure the pelvic diameters of clinical relevance. Measurements were conducted by two diagnostic imaging specialists. The mean and standard deviation of the measured diameters were: anatomical conjugate diameter (ACD) 11.65±0.99 cm, the obstetric conjugate diameter (OCD) 11.73±0.98 cm, diagonal conjugate diameter (DCD) 12.49±0.98 cm and Interspinous distance (ISD) 10.41±0.78 cm. Significant differences were found in all four mean diameters in between the 20-29 age groups versus the >40, as well as between the 30-39 groups versus the >40. Our study shows that as Mexican women get older, the mean pelvic diameters become narrower.

“…It has been suggested that the ultrasound image produced by this approach is an objective and reproducible technique for the prediction of vaginal delivery [32]- [35]. By using this ultrasound approach a narrow angle of progression (<95) corresponding to a high station was associated with a high rate of caesarean section in non-labouring nulliparous at term [36]- [38]. In the present study we report an association between high foetal head station before labour and obstructed labour.…”

Aim: To evaluate an innovative sonopelvimetry method for early prediction of obstructed labour. Methods: A prospective study was conducted in two centers. GPS-based sonopelvimetry, laborPro TM (Trig Medical Inc., Yoqneam Ilit, Israel) devise, was used prior to labour in nulliparous women at 39 -42 weeks gestation remote from labor. Maternal pelvic parameters, including inter-iliac transverse diameter, obstetric conjugate and interspinous diameter were evaluated. Fetal parameters included head station, biparietal diameter and occipitofrontal diameter. Data on delivery and outcome were collected from the electronic files. Results: The innovative use of sonopelvimetry was applied to 154 consecutive women, none of the participants complained of discomfort or complications observed. The mean time of examination was 15 + 2 minutes. Mean time of examination to delivery interval was 4.8 days (range 0 -16 days). Small interspinous diameter and high head station were the best predictors for obstructed labour. Analysis indicated 87% sensitivity and 61% specificity for birth weight fetal head station and ISD combined in predicting obstructed labour with an area under the curve of 0.77. Conclusions: Our results indicate that GPS-based sonopelvimetry combined with fetal estimated weight is a valuable tool in the risk assessment of obstructed labour. Parameters obtained by sonopelvimetry combined with birth weight may be useful.

“…Th is diameter is highly signifi cant from a clinical perspective. On the one hand, various studies demonstrated that the narrow bispinous diameter and the narrow diameters of the outlet increase the risk of prolonged labor and emergence cesarean section [3,7,12,21]. On the other hand, the wider bispinous diameter increases the risk of the pelvic fl oor disorders in females [14,19].…”

The aim of this study was to specify the predictors of the narrowest pelvic diameter in females and males. Possible common tendencies and sexual dimorphism in this prediction are in question for measures in live humans. In addition, the relationship between the false pelvis and the true pelvis was not explored in males. The research sample included 211 females and 181 males, who underwent the computer tomography examination in the Hospital Gailezers, Latvia. Three-dimensional pelvic images were used for 12 linear measurements (8 diameters of the pelvic cavity in four pelvic levels, conjugata diagonalis, and 3 diameters of the false pelvis). The results demonstrated that the most powerful predictors of the bispinous diameter are the transverse diameter of the inlet and the bituberous diameter. These predictors are significant for both sexes. Sexual dimorphism manifests itself in a greater number of predictors and higher variance explained by these predictors in females. There is no statistical evidence for an accurate prediction of the bispinous diameter based on the diameters of the false pelvis.
