Pelvimetry is the assessment of the female pelvis in relation to the birth of a baby. Traitional obstetrical services relied heavily on pelvimetry in the conduct of delivery in order to decide if natural or operative vaginal delivery was possible or if and when to use a cesarean section. With the increased safety of modern cesarean section and increased medico legal concerns about use of operative vaginal delivery, the threshold to perform a cesarean section has decreased and the need for pelvimetry diminished.
