Denman's spontaneous evolution

Etymology: Thomas Denman, English physician, 1733-1815; L, sponte, voluntarily, evolvere, to roll forth
a natural, unassisted turning of the fetus from the transverse presentation. The head rotates back, and, as the breech descends, the shoulder ascends in the pelvis. The back of the fetus is generally posterior. Also called Denman's method, Denman's spontaneous version.
