Which describes the three main breech presentations?

• A. Frank breech: hips flexed, knees extended; Complete breech: hips and knees flexed; Incomplete breech: one or both hips extended; includes footling and kneeling
• B. Frank breech: hips extended, knees flexed; Complete breech: hips and knees extended; Incomplete breech: hips flexed
• C. Frank breech: head first; Complete breech: buttocks first; Incomplete breech: feet first
• D. Frank breech: hips flexed; Complete breech: hips flexed and knees extended; Incomplete breech: both hips extended

Answer: (A)

Breech presentations are classified by how the hips and knees are positioned, which determines which part presents first. In frank breech, the hips are flexed and the knees are extended, so the buttocks present first with the legs extended upward toward the head. In complete breech, both the hips and knees are flexed, so the buttocks present with the legs folded and the feet closer to the face. In incomplete breech, the hips are extended, so the presenting part can be a foot or a knee rather than the buttocks, and this includes subtypes where feet (footling) or knees (kneeling) present first. This description lines up with the statement that the three main breech presentations are frank (hips flexed, knees extended), complete (hips and knees flexed), and incomplete (hips extended, with footling or kneeling variants).
