Wigand-Martin Winckel Handle

The Wigand-Martin-Winckel Handle is an obstetrical maneuver for the development of the child at a breech position when the following head does not enter the pelvis.

The middle finger of the obstetrician's inner hand is introduced into the mouth of the child, the second and fourth fingers of the same hand lie on the cheekbones. The head is bent and the arrow seam in the basin entrance is crossed. By pulling on the head and shoulders, the head is brought from above through the pelvic region, and then developed with the Veit-Smellie handgrip, at the same time as the Kristeller handle.

The Wigand Martin Winckel handle is named after Justus Heinrich Wigand (1769-1817), August Eduard Martin (1847-1933) and Franz von Winckel (1837-1911). It is also called "Dreimännerhandgriff." Edit sourcetext
