A transverse presentation, if unaided by art, may have five possible terminations: 1. Impaction, with excessive retraction of the upper uterine fibers, rupture and death of mother and fetus from hemorrhage or exhaustion. This is by far the most common outcome of neglected shoulder presentations. 2. Spontaneous birth by a doubled body, the condition termed "evolutio conduplicato corporis" by Roderer, in which the head and thorax are jammed tightly into each other and are born together. 3.
