Shoulder dystocia is a problem during birth. The baby’s head has been born but the shoulders are stuck. The shoulder becomes trapped against the mother’s pubic bone.
Most babies will be able to be born safely with some help. Sometimes the baby may be stuck in the birth canal too long, which can cause some problems.
Problems for the baby may include:
- Lack of oxygen
- Broken arm or collarbone
- Arm nerve damage
Problems for the mother may include:
- Tearing or bruising of the cervix, rectum, or vagina
- Bruising to the bladder
- Severe bleeding

The doctor or midwife will know when the birth process stops after the head is born.
Prenatal tests will estimate the size of the fetus and the mother’s pelvis. These tests may show a risk for shoulder dystocia.
An ultrasound may be done before labor. The doctor will be able to see if the baby is too large to fit safely through the birth canal. A vaginal delivery may not be a safe method if the baby is too large.
The care team will act fast if a shoulder dystocia occurs. The goal is to release the baby as fast as possible. This will allow the vaginal birth to continue. The doctor or midwife may:
- Reposition the mother
- Reposition the baby to try to move the shoulder away from the bone
A C-section may be needed if the baby remains stuck in the birth canal.
