A birth injury is structural damage or functional impairment a newborn suffers during labor, delivery, or immediately after, caused by mechanical forces or oxygen deprivation rather than genetic factors. According to the NIH StatPearls clinical reference (2025), the rate of birth trauma in the United States declined from 2.6 to 1.9 per 1,000 live births between 2004 and 2012, with roughly 80% of cases classified as moderate to severe. The condition is distinct from a birth defect, which forms in the womb due to genetic or developmental causes and, according to the CDC, affects about 1 in 33 babies born in the U.S. In New York, when a birth injury results from a healthcare provider falling below the accepted standard of care, families have specific legal rights under New York Civil Practice Law and Rules § 214-a and § 208 to pursue compensation for their child's lifetime needs.

What Is a Birth Injury in Medical and Legal Terms?
A birth injury is harm caused to a newborn by an event that occurs during labor, delivery, or the immediate perinatal period. The peer-reviewed definition published in Cureus and indexed by the National Library of Medicine describes it as "structural damage or functional deterioration of a newborn secondary to a traumatic event that occurred during labor, delivery or both." The 2025 update of the NIH StatPearls clinical reference uses a slightly broader term, "birth trauma," to encompass both physical injury and psychological trauma to the newborn and the birthing parent.
The legal use of the term tracks the medical one. New York courts treat a birth injury as an acquired condition, meaning the child was developing normally until something happened during the delivery process. That distinction matters because acquired injuries can support a medical malpractice claim under New York law, while purely congenital conditions generally cannot.
Two clarifying points from the medical literature. Injuries that happen before labor begins, such as those caused by amniocentesis or intrauterine transfusion, are not classified as birth injuries. Neither are injuries from postnatal resuscitation. However, harm caused by fetal scalp electrodes or intrapartum heart-rate monitoring during labor does qualify.
What Counts as a Birth Injury Versus a Birth Defect?
The single most important distinction in this area of medicine and law is the difference between a birth injury and a birth defect. They are caused by different things, treated differently, and produce very different legal outcomes.
| Birth Injury | Birth Defect | |
| When it happens | During labor, delivery, or shortly after | In the womb, usually in the first trimester |
| Cause | Mechanical force, oxygen deprivation, instrument misuse, or other delivery event | Genetic, chromosomal, or developmental factor; sometimes environmental |
| Frequency in U.S. | About 1.9 per 1,000 live births (NIH StatPearls, 2025) | About 1 in 33 births, or roughly 3% (CDC) |
| Examples | Cerebral palsy from oxygen deprivation, Erb's palsy, skull fracture, hypoxic-ischemic encephalopathy | Down syndrome, cleft palate, spina bifida, congenital heart defects |
| Preventable? | Often, with proper standard of care | Generally not preventable through delivery-room care |
| Legal claim? | May support medical malpractice action | Generally does not support malpractice action |
A child can have both a birth injury and a separate, unrelated birth defect. A skilled birth injury attorney works with medical experts to separate the two and identify what was caused by the delivery itself.
How Common Are Birth Injuries in the United States and New York?
According to the NIH StatPearls Birth Trauma chapter (2025), the rate of birth trauma in the United States declined from 2.6 to 1.9 per 1,000 live births between 2004 and 2012, a trend the authors attribute to fewer operative vaginal deliveries and a corresponding rise in cesarean sections. Applied to 2024 U.S. birth volume of roughly 3.6 million, that translates to thousands of affected newborns each year, with roughly 80% classified as moderate to severe. Older sources, including some still cited by hospital systems, place the figure as high as 6 to 7 per 1,000 live births. The lower number from StatPearls reflects more recent peer-reviewed surveillance data.
In New York, the March of Dimes 2025 Report Card shows 19,458 babies were born preterm in 2024, a preterm birth rate of 9.5%. Cesarean delivery accounted for 33.8% of New York live births in 2024. Both figures matter because preterm birth and the way a delivery is conducted are among the strongest predictors of birth injury risk.
The most common single birth injury in the U.S. is a fractured clavicle, which Stanford Medicine Children's Health identifies as the most common fracture sustained during labor and delivery. Reported incidence in the peer-reviewed literature ranges from roughly 0.5% to 4% of births, or about 5 to 40 per 1,000 live births, with most cases healing without complications. The most common serious neurological birth injury is cerebral palsy, which the CDC reports affects approximately 1 in 345 children, with about 10,000 babies diagnosed each year.
The Most Common Types of Birth Injuries
The following conditions appear most frequently in the medical and legal record. Each entry below is drawn from the 2025 NIH StatPearls Birth Trauma reference and the peer-reviewed literature review of neurological neonatal birth injuries hosted on the National Library of Medicine.
Cerebral Palsy
Cerebral palsy (CP) is a group of disorders that affect a person's ability to move and maintain balance and posture, defined by the CDC as the most common motor disability in childhood. CP is caused by abnormal brain development or damage to the developing brain. Roughly 80% of CP cases are spastic CP, which produces stiff muscles and awkward movement. The remaining types are dyskinetic, ataxic, and mixed.
About 10,000 babies are diagnosed with CP in the U.S. each year, and approximately 764,000 children and adults currently live with the condition. Although the CDC notes that 85% to 90% of CP cases are congenital and the specific cause is often unknown, a meaningful subset is linked to oxygen deprivation or trauma during labor and delivery, which is when malpractice questions arise. (See Porter Law Group's cerebral palsy practice page for more.)
Hypoxic-Ischemic Encephalopathy (HIE)
Hypoxic-ischemic encephalopathy is a brain injury that happens before, during, or shortly after birth when oxygen or blood flow to the brain is reduced or stopped. The National Institute of Neurological Disorders and Stroke treats HIE as an umbrella term that also includes birth asphyxia, perinatal asphyxia, and neonatal encephalopathy.
HIE occurs in approximately 1 to 3 per 1,000 full-term live births in developed countries. The outcomes are severe. Roughly 15% to 20% of affected newborns die in the postnatal period, and another 25% develop permanent neurological consequences such as cerebral palsy, epilepsy, cognitive disabilities, or hearing and vision impairments. Therapeutic hypothermia, also called cooling treatment, can reduce permanent damage if started within hours of birth, which is why timely recognition by the medical team is critical.
Erb's Palsy and Other Brachial Plexus Injuries
Brachial plexus injuries are caused by stretching or tearing of the network of nerves that runs from the neck through the shoulder. They occur in up to 2.5 per 1,000 live births and are most often associated with shoulder dystocia, large birth weight (macrosomia), prolonged extraction, breech delivery, and operative delivery using forceps or vacuum.
Erb-Duchenne palsy, commonly called Erb's palsy, accounts for about 80% of brachial plexus injuries. It involves damage to the C5 and C6 nerve roots and produces the classic "waiter's tip" arm posture. Klumpke's palsy, which involves the C8 and T1 nerve roots, affects the muscles of the hand and is rarer and less likely to resolve. Total arm paralysis occurs when all nerve roots are damaged. Roughly 70% to 95% of Erb's palsy cases resolve within a year, but 5% to 8% are permanent. (Porter Law Group's Erb's palsy practice page covers the legal and medical specifics in depth.)
Caput Succedaneum
Caput succedaneum is soft tissue swelling on the newborn's scalp caused by pressure during delivery. The swelling crosses suture lines, which distinguishes it from a cephalohematoma. Most cases resolve on their own within four to six days without treatment. Persistent or unusually large swelling beyond 48 to 72 hours, or any case accompanied by neurological symptoms, warrants imaging.
Cephalohematoma
A cephalohematoma is a collection of blood between a newborn's skull and the periosteum, the membrane covering the bone. According to the StatPearls reference, it affects up to 2.5% of all births and is significantly more common with instrument-assisted delivery. The risk increases roughly 4 to 5 times with forceps, 8 to 9 times with vacuum extraction, and 11 to 12 times when both are used in sequence. Most cases resolve within two weeks to three months. Possible complications include calcification, skull deformities, infection, and osteomyelitis.
Subgaleal Hemorrhage
Subgaleal hemorrhage is bleeding into the loose tissue space between the scalp's aponeurosis and the skull's periosteum. It is rare but dangerous because the space can hold more than 40% of a newborn's total blood volume, leading to hypovolemic shock. The condition occurs in approximately 4 per 10,000 spontaneous vaginal deliveries and 59 per 10,000 vacuum-assisted deliveries. Mortality from a subgaleal bleed has been reported as high as 14% when not promptly recognized.
Intracranial Hemorrhages
Intracranial hemorrhages are bleeds inside the skull and are among the most serious birth injuries. The four main types differ by location.
- Subdural hemorrhage is the most common type in newborns, often associated with operative vaginal delivery.
- Subarachnoid hemorrhage is the second most common, typically caused by rupture of bridging veins.
- Epidural hemorrhage is rare and usually accompanies a linear skull fracture.
- Intraventricular hemorrhage is most often seen in premature infants but can occur in term infants after significant birth trauma.
Skull Fractures
Skull fractures from delivery are most often linked to instrument-assisted vaginal delivery. They can be linear or depressed. Linear fractures often go undetected without imaging because they may produce no immediate symptoms. Any neurological sign in a newborn following a difficult delivery is a reason for CT or MRI evaluation.
Facial Nerve Injuries
Facial nerve palsy in newborns most often results from pressure on the facial nerve trunk, either from forceps blades or from prolonged contact with the mother's pelvic bones during a difficult labor. The first visible sign is usually that the affected eye does not close fully. Most cases resolve within the first two months of life, though severe injuries can require surgical intervention.
Fractured Clavicle
A fractured collarbone is the single most common birth injury, with peer-reviewed incidence rates ranging from roughly 0.5% to 4% of births (about 5 to 40 per 1,000 live births), depending on the study population. It is most often associated with shoulder dystocia, large birth weight, or difficult extraction. Most clavicle fractures heal on their own within a few weeks. The legal question is usually not the fracture itself but whether the underlying delivery management met the standard of care.
Subconjunctival and Retinal Hemorrhages
Pressure during delivery can rupture small blood vessels in a newborn's eye. The literature review hosted on the National Library of Medicine reports that retinal hemorrhage occurs in approximately 75% of vacuum-assisted deliveries, 33% of spontaneous vaginal deliveries, and only 6.7% of cesarean deliveries. The disparity is one of the strongest indicators that delivery method directly influences eye injury risk.
What Causes Birth Injuries?
Birth injury risk factors fall into three categories defined by the StatPearls clinical reference: factors related to the baby and pregnancy, factors related to the birthing parent, and iatrogenic factors, which means factors caused by medical intervention. Understanding which category applies is essential to understanding whether negligence may have played a role.
Fetal and Pregnancy Factors
Several characteristics of the baby or the pregnancy increase the risk of injury during delivery. Macrosomia, defined as a birth weight above 4,000 grams, doubles the risk of birth injury. A weight between 4,500 and 5,000 grams triples it, and a weight above 5,000 grams increases it more than 4.5 times. Other significant fetal and pregnancy factors include macrocephaly (an unusually large head), very low birth weight, extreme prematurity, oligohydramnios (low amniotic fluid), and any abnormal fetal presentation, including breech, face, brow, or transverse positioning.
Maternal Factors
Several maternal factors raise the risk profile of a delivery. These include obesity, pre-existing or pregnancy-onset diabetes, hypertension, cephalopelvic disproportion (a mismatch between the baby's size and the pelvis), small maternal stature, first pregnancy (nulliparity), labor dystocia (prolonged or obstructed labor), and either rapid or unusually prolonged labor.
Medical and Delivery-Related Causes
Iatrogenic causes are the category where malpractice questions arise most often. Vacuum extraction increases birth injury risk roughly threefold compared with unassisted vaginal delivery, and forceps use increases it roughly fourfold. Sequential use of both vacuum and forceps in the same delivery should not be routinely performed because of the higher rate of neonatal complications, according to American College of Obstetricians and Gynecologists Practice Bulletin No. 219 on operative vaginal birth.
Other delivery-related causes that frequently appear in birth injury cases include failure to monitor fetal heart rate and respond to signs of fetal distress, delayed decision to perform a cesarean section when distress is documented, improper administration of labor-inducing medications such as Pitocin (which can cause hyperstimulation of the uterus), and failure to recognize and respond to shoulder dystocia.
When Is a Birth Injury Considered Medical Malpractice in New York?
A birth injury becomes medical malpractice when a healthcare provider fails to meet the accepted standard of care and that failure causes harm to the child or birthing parent. Not every birth injury is malpractice. Some injuries occur even with flawless care, particularly in high-risk deliveries. The legal question is whether a competent obstetrician, nurse, or hospital, in the same circumstances, would have acted differently and avoided the injury.
The standard of care is usually defined through expert testimony. Practice bulletins from the American College of Obstetricians and Gynecologists are heavily relied upon. ACOG Practice Bulletin No. 219, for example, sets out specific prerequisites that must be met before forceps or vacuum can be used: the cervix must be fully dilated, the membranes ruptured, the fetal head engaged at station 0 or below, the position known, gestational age at least 34 weeks for vacuum, and the capability to perform an emergency cesarean immediately available. A delivery conducted without those prerequisites that results in injury is a strong indicator of a deviation from the standard of care.
New York requires plaintiffs to back this up procedurally. Under New York Civil Practice Law and Rules § 3012-a, every medical malpractice complaint must be accompanied by a Certificate of Merit. That certificate is a sworn statement from the plaintiff's attorney confirming that a qualified medical expert has reviewed the case and concluded there is a reasonable basis for the lawsuit.
How Long Do You Have to File a Birth Injury Lawsuit in New York?
New York has some of the most complex statute of limitations rules in the country for birth injury cases, and missing a deadline almost always ends a case permanently.
| Type of Claim | Deadline | Statute |
| Child's medical malpractice claim | Up to 10 years from the date of malpractice | CPLR § 208 (infancy toll) |
| Parents' personal claims (emotional distress, lost services) | 2 years and 6 months from the malpractice | CPLR § 214-a |
| Wrongful death | 2 years from the date of death | NY Estates, Powers and Trusts Law § 5-4.1 |
| Public hospital claims (Notice of Claim) | 90 days from the malpractice | General Municipal Law § 50-e |
| Public hospital lawsuit filing | 1 year and 90 days from the malpractice | General Municipal Law § 50-i |
A few points often catch families off guard. The 10-year rule is a hard cap, not a starting point. If a child's birth injury is not discovered until age 11, the medical malpractice clock has already run out. Parents' separate claims for their own damages do not get the benefit of the infancy toll. And if the birth occurred at a New York City Health and Hospitals facility, a SUNY medical center, or any other municipal hospital, a Notice of Claim must be served within 90 days, with a lawsuit to follow within 1 year and 90 days. (Lavern's Law, the 2018 amendment to CPLR § 214-a, applies only to failure-to-diagnose-cancer cases. It does not extend birth injury deadlines, despite occasional confusion. See Porter Law Group's explanation of Lavern's Law for more.)
How Do You Know If Your Child's Birth Injury Was Preventable?
Some of the strongest indicators that a birth injury may be linked to negligence are events that signal something went wrong during delivery. These include emergency interventions or sudden mode-of-delivery changes (for example, a rushed cesarean after prolonged distress), unexpected admission to the neonatal intensive care unit (NICU), seizures or abnormal movements in the first 24 to 48 hours of life, an Apgar score that remains low past five minutes, evidence of oxygen deprivation in cord blood gas tests, signs of trauma such as bruising or fractures, and difficulty feeding or breathing in a previously full-term, healthy pregnancy.
None of these by themselves prove malpractice. Together, and combined with a careful review of fetal monitoring strips, hospital protocols, and the obstetric team's documented decisions, they can establish that the standard of care was breached. The only reliable way to know is a free case review by a New York medical malpractice attorney with experience in birth injury cases.

Frequently Asked Questions About Birth Injuries
What is the most common birth injury?
The single most common birth injury in the United States is a fractured clavicle (collarbone), with peer-reviewed incidence rates ranging from roughly 0.5% to 4% of births (about 5 to 40 per 1,000 live births). The most common serious neurological birth injury is cerebral palsy, which the CDC reports affects 1 in every 345 children. Cephalohematoma, soft tissue scalp swelling, and brachial plexus injuries are also common, particularly after instrument-assisted delivery.
What is the difference between a birth injury and birth trauma?
The two terms are often used interchangeably, but they are not identical. "Birth injury" usually refers to the physical harm a newborn suffers during labor and delivery. "Birth trauma," as used in current clinical literature like the 2025 NIH StatPearls reference, is broader and includes both the physical injuries and the psychological harm that the birthing parent or partner can experience after a difficult or traumatic delivery. In a legal context in New York, the relevant concept is birth injury, meaning the physical harm to the child.
Are all birth injuries caused by medical malpractice?
No. Some birth injuries occur even when every member of the medical team meets the standard of care, especially in high-risk pregnancies. The legal question is not whether an injury happened but whether a competent healthcare provider in the same situation would have prevented it. A free case review with a birth injury attorney is the only reliable way to know whether your child's injury could have been avoided.
How much does it cost to hire a birth injury lawyer in New York?
Reputable New York birth injury law firms, including Porter Law Group, handle these cases on a contingency fee basis. That means no upfront fees, no hourly billing, and no out-of-pocket costs. The firm advances all case expenses, including expert witness fees and medical record costs, and is paid only if the case is resolved in the client's favor.
What is the statute of limitations for a birth injury lawsuit in New York?
The child has up to 10 years from the date of the malpractice to file under New York CPLR § 208, the infancy toll. Parents' separate claims for their own damages must be filed within 2 years and 6 months under CPLR § 214-a. A wrongful death claim must be filed within 2 years of the date of death. If the injury occurred at a public or municipal hospital, a Notice of Claim must be served within 90 days under General Municipal Law § 50-e.
Is cerebral palsy always caused by a birth injury?
No. The CDC reports that 85% to 90% of cerebral palsy cases are congenital, meaning the brain damage occurred before or during birth, and that in many cases the specific cause is not known. A meaningful subset of CP cases, however, is linked to oxygen deprivation, untreated infections, or trauma during labor and delivery. When the medical record shows preventable causes of brain injury at the time of delivery, those cases can support a malpractice claim.
What is the average settlement for a birth injury lawsuit?
There is no meaningful "average" because the value of a case depends entirely on the severity of the injury and the lifetime cost of care. Severe birth injury cases involving lifelong disability commonly resolve in the seven and eight figures because they must fund decades of medical care, therapy, equipment, and lost earning capacity. Porter Law Group's recent results page lists multiple birth injury settlements above $8 million.
What evidence is needed to prove a birth injury case in New York?
The core evidence in a New York birth injury case typically includes the complete prenatal and labor and delivery records, fetal heart-rate monitoring strips, hospital protocols and policies that applied at the time, staffing and credentialing records for the providers involved, the newborn's NICU and pediatric records, and expert testimony from board-certified obstetricians and pediatric neurologists. The law firm gathers these records, retains the experts, and prepares the Certificate of Merit required under CPLR § 3012-a.
Can I still sue if my child's birth injury happened years ago?
Possibly. The infancy toll under CPLR § 208 keeps the clock open for up to 10 years from the date of the malpractice for the child's claim, even though the standard adult medical malpractice statute is 2 years and 6 months. The sooner you contact an attorney, the better, because evidence and witness recollection deteriorate over time. If your child is approaching age 10 or you are unsure how the deadlines apply to your situation, contact Porter Law Group immediately at 833-PORTER9.
Should I talk to the hospital or insurance company before hiring a lawyer?
No. Hospital risk management and insurance representatives work for the hospital, not for your family. Statements made early, even in conversations meant to be sympathetic, can be used later to limit the case. Speak with a New York birth injury attorney first. Porter Law Group offers a free, no-obligation case review.
