However, two-dimensional (2D) ultrasound is not sufficient to demonstrate the ischial spines and other important \u201clandmarks\u201d of the female pelvis. Therefore, the purpose of this study was to evaluate the distance of the interspinous plane as a parallel line to the infrapubic line in 2D ITU with the help of 3D computed tomography and digital reconstruction.<\/jats:p><jats:p>Mean distance between the infrapubic plane and the tip of the ischiadic spine was 32.35 (\u00b14.46) mm. The mean height was 166 (\u00b17) cm; the mean weight was 67.5 (\u00b118.4) kg. Body height and the measured distance were significantly correlated (P=0.025; correlation coefficient of 0.5), whereas body weight was not (P=0.37; correlation coefficient of \u20130.214).<\/jats:p><jats:p>With the present results, clinicians were enabled to transfer the reproducible measurements of the \u201chead station\u201d by ITU to the widespread but observer-depending vaginal examination. Furthermore, ITU can be verified as an objective method in comparison to subjective palpation with the ability to optimize the evaluation of the head station according to bony structures as landmarks in a standardized application.<\/jats:p>","DOI":"10.1515\/jpm-2015-0395","type":"journal-article","created":{"date-parts":[[2016,3,16]],"date-time":"2016-03-16T15:31:12Z","timestamp":1458142272000},"source":"Crossref","is-referenced-by-count":11,"title":["Correlation
