Eicher used the McRoberts maneuver by positioning the mother's legs to maximize the potential opening for the baby to pass through; he also applied subpubic
pressure by having a nurse apply pressure on the mother's pubic bone to dislodge the impacted shoulder; that as the nurse applied such pressure, he applied traction; and that baby was delivered.
Twenty-one radiological studies were carried out during subpubic injections (7) in cadavers.
After establishing general anaesthesia, the penis and subpubic region are prepared with 0.
The subpubic space when viewed in the mid-line sagittal plane is a triangle defined inferiorly by deep penile fascia (Buck's) encasing the penile neurovascular bundle and the corpora cavernosa, superiorly by the pubic symphysis and anteriorly by the membranous layer of the superficial fascia (Scarpa's).
