A twin birth injury involving the second twin is a specific and well-documented clinical scenario. When a mother delivers twins, the interval between the delivery of the first and second baby — and the obstetric management of twin B during that interval — is a critical period governed by established clinical guidelines. If the second twin was injured during delivery, understanding the standard of care that applied, what went wrong, and who is responsible requires careful analysis of the operative and delivery records.

The Second Twin’s Unique Risk Profile
Research consistently shows that the second-born twin faces higher perinatal risk than the first. The second twin is subject to: a potentially prolapsed umbilical cord after the first twin is delivered and the uterus partially decompresses; malpresentation (breech or transverse lie) that may require internal podalic version or breech extraction; placental abruption triggered by the change in uterine volume after the first delivery; and reduced uteroplacental circulation if delivery is delayed. Peer-reviewed literature, including studies by Leung et al. and Stein et al., has examined the relationship between inter-twin delivery interval and adverse outcomes for twin B, and ACOG Practice Bulletin 231 on multifetal gestations addresses delivery management for both twins.
Inter-Twin Delivery Interval: What ACOG Guidelines Require
ACOG Practice Bulletin 231 addresses the management of multifetal gestations, including the timing and mode of delivery for twin B. The Bulletin does not mandate a specific maximum number of minutes between deliveries as a bright-line rule, but it does require continuous electronic fetal monitoring of the second twin throughout the first twin’s delivery and the interval that follows, and it directs that the delivery team be prepared to promptly deliver twin B if fetal heart rate abnormalities develop.
The question in a birth injury case is not whether a specific number of minutes elapsed — it is whether the clinical team was continuously monitoring twin B’s fetal heart rate, responded appropriately to any decelerations or bradycardia detected during the inter-twin interval, and had the skill and equipment available to perform an expedited delivery when indicated. A prolonged interval alone is not necessarily negligent; a prolonged interval during which the team failed to monitor or failed to act on detected fetal distress is a different matter.
Mode of Delivery for Twin B: Breech Extraction and Internal Version
When twin B is in a non-vertex (non-head-first) presentation, the delivering obstetrician may need to perform an internal podalic version — manually rotating the baby within the uterus — followed by breech extraction, in which the physician delivers the baby feet-first. These are skilled maneuvers that require specific training and should be performed under continuous ultrasound guidance. ACOG Practice Bulletin 231 addresses the evidence base for these techniques in multifetal deliveries.
Errors in the execution of internal version or breech extraction — including excessive traction, failure to use ultrasound guidance, or performing the maneuver without adequate preparation — can cause direct physical injury to twin B, including brachial plexus injury, cervical spine injury, or traumatic hypoxia. These are distinct injury mechanisms from the oxygen-deprivation injuries that can also occur during this period, and the clinical records typically document which occurred.
Continuous Monitoring Obligations During Twin Labor
A critical standard-of-care issue in twin delivery cases is whether both twins were continuously monitored throughout the labor and delivery process. External fetal monitoring equipment must be positioned to capture heart rate tracings for each twin separately. After the first twin is delivered, internal monitoring of twin B may be indicated to maintain continuous tracing until delivery. Gaps in the monitoring record — periods during which twin B’s fetal heart rate was not documented — are clinically significant findings that a birth injury attorney and reviewing expert will examine carefully.
When monitoring gaps coincide with the development of neonatal neurological injury in twin B, the evidentiary link between the monitoring failure and the outcome becomes a central issue in the case. If the injury resulted in oxygen deprivation affecting the brain, our attorneys who handle HIE and infant brain damage from birth can evaluate that aspect of the claim as part of a comprehensive review of the twin delivery.
How a Twin Birth Injury Case Is Evaluated Under Illinois Law
A birth injury malpractice claim arising from a twin delivery is a healing-art claim subject to Illinois requirements, including the 2-622 affidavit requirement under 735 ILCS 5/2-622. Before a complaint may be filed, an attorney must obtain a written certification from a qualified reviewing health professional confirming that the claim has reasonable and meritorious cause. In a twin delivery case, the reviewing expert will typically be a maternal-fetal medicine specialist or obstetrician with experience in multifetal gestations.
The review must assess: whether the delivery team complied with ACOG Practice Bulletin 231 guidance on twin delivery management; whether continuous monitoring was maintained for twin B; whether the inter-twin interval was managed appropriately given the clinical picture; whether the mode of delivery for twin B was indicated and executed correctly; and whether the hospital was appropriately staffed for a twin delivery, including the availability of neonatal resuscitation personnel for each baby at the time of delivery.
