Wood's screw maneuver is practiced in obstetrics when dealing with shoulder dystocia – a condition in which the fetal shoulders cannot easily pass through the vagina.In this maneuver the anterior shoulder is pushed towards the baby's chest, and the posterior shoulder is pushed towards the baby's back, [1] making the baby's head somewhat face the mother's rectum.
Shoulder dystocia occurs after vaginal delivery of the head, when the baby's anterior shoulder is obstructed by the mother's pubic bone. [ 3 ] [ 1 ] It is typically diagnosed when the baby's shoulders fails to deliver despite gentle downward traction on the baby's head, requiring the need of special techniques to safely deliver the baby.

Obstructed labour, also known as labour dystocia, is the baby not exiting the pelvis because it is physically blocked during childbirth although the uterus contracts normally. [2] Complications for the baby include not getting enough oxygen which may result in death. [ 1 ]
Rubin's I and II maneuvers, rotational maneuver to deliver the baby in case of shoulder dystocia. [1] The Rubin's I maneuver is dislodging the anterior shoulder under pubic symphysis by adding suprapubic pressure while in the McRoberts' position. As a result, the bisacromial diameter is rotated from anteroposterior to oblique lie.
Use for shoulder dystocia is controversial. [ 5 ] Currently the procedure is rarely performed in developed countries, but is still performed in "rural areas and resource-poor settings of developing countries" [ 7 ] where caesarean sections are not available, or where obstetricians may not be available to deliver subsequent pregnancies. [ 8 ]
The Zavanelli maneuver is an obstetric maneuver that involves pushing back the delivered fetal head into the birth canal in anticipation of performing a cesarean section in cases of shoulder dystocia. [1] [2] The Zavanelli maneuver is performed only after other maneuvers have failed, as it is associated with high risk to both the mother and the ...
This can cause issues as pregnancy progresses, such as difficulty carrying the fetus to full term. Another complication that can occur during human childbirth is shoulder dystocia, where the shoulder is stuck in the birth canal. [13] This can lead to fractured humerus and clavicle of the fetus and hemorrhaging of the mother postpartum. [13]
Fetal distress, also known as non-reassuring fetal status, is a condition during pregnancy or labor in which the fetus shows signs of inadequate oxygenation. [1] Due to its imprecision, the term "fetal distress" has fallen out of use in American obstetrics. [2] [1] [3] The term "non-reassuring fetal status" has largely replaced it. [4]
