clinical pelvimetry, assessment of the bony pelvic portion of the birth canal by systematic pelvic and rectovaginal examination at the start of prenatal care and usually again in the first pelvic examinations in labor. Findings may be expressed in several ways: (1) clinical interpretations of adequate, borderline, or inadequate, (2) by Caldwell-Moloy type, (3) estimation of the length of the pelvic diameters associated with labor (including obstetric conjugate, interspinous diameter, transverse diameter, diagonal conjugate). Compare x-ray pelvimetry. See also birth canal, cephalopelvic disproportion, dystocia.
