Fetal malpresentation and fetal malposition are frequently interchanged; however, fetal malpresentation refers to a fetus with a fetal part other than the head engaging the maternal pelvis. Fetal malposition in labor includes occiput posterior and occiput transverse positions. Both fetal malposition and malpresentation are associated with significant maternal and neonatal morbidity, which have significant impact on patients and providers. Accurate diagnosis of both conditions is necessary for appropriate management. In this review, terminology, incidence, diagnosis, and management are discussed.
胎儿胎位异常和胎儿位置异常经常互换使用；然而，胎儿胎位异常是指胎儿的除头部以外的身体部位先进入母体骨盆。产时胎儿位置异常包括枕后位和枕横位。胎儿位置异常和胎位异常均与产妇和新生儿发病率显著相关，对患者和医护人员均有重大影响。准确诊断这两种情况对于适当的处理是必要的。本文讨论了术语、发病率、诊断和处理。
