Risk Factors

Some of the factors that can cause a woman to be at a higher risk for malpresentation are an abnormally shaped uterus, limited pelvis size, fibroids, twins, placenta previa, or too much or too little amniotic fluid. Women who have had many previous children are also at risk because their abdominal muscles are often more lax and fail to keep the uterine cavity upright. Premature babies and babies with decreased muscle tone also have a higher incidence of malpresentation.
