When a child is diagnosed with diplegic cerebral palsy—a condition primarily affecting both legs—families face not only significant medical challenges but also difficult questions about what caused it. While some cases of spastic diplegia occur naturally, many result from preventable medical errors during pregnancy, labor, or delivery. In New York, families have the legal right to pursue compensation when medical negligence causes this life-altering condition.
This comprehensive guide explains what diplegic cerebral palsy is, how it develops, when it constitutes medical malpractice, and your legal options under New York law.

What Is Diplegic Cerebral Palsy?
Diplegic cerebral palsy, also called spastic diplegia, is a type of cerebral palsy characterized by muscle stiffness (spasticity) that primarily affects both legs. The arms may be affected to a lesser extent or not at all. This condition results from damage to the motor cortex or white matter of the brain, which disrupts the signals controlling muscle movement and coordination.
According to the Centers for Disease Control and Prevention (CDC), cerebral palsy affects approximately 1 to 4 per 1,000 children, with spastic types being the most common. Spastic diplegia accounts for a significant portion of these cases, particularly among children born prematurely.
Characteristic Symptoms
Children with diplegic cerebral palsy typically exhibit:
Primary Motor Symptoms
- Scissoring gait: Legs cross when walking due to tight hip adductor muscles
- Toe walking: Difficulty placing heels on the ground
- Stiff, contracted leg muscles (spasticity)
- Difficulty crawling or walking without assistance
- Poor balance and coordination
Associated Symptoms
- Speech and swallowing difficulties
- Vision problems or deficits
- Joint contractures (permanent muscle tightening)
- Seizures (in some cases)
- Cognitive impairment (varies in severity)
- Delayed achievement of motor milestones
Understanding Scissoring Gait
The characteristic “scissoring gait” occurs when high muscle tone (spasticity) in the hip adductors—the muscles that bring the thighs together—causes the legs to cross at the knees while walking. This happens because these muscles remain in a constant state of contraction, forcing the upper legs inward. Meanwhile, the opposing muscles (abductors) weaken from lack of use, creating a distinctive walking pattern where the knees and thighs hit or even cross with each step.
The Connection Between PVL and Spastic Diplegia
One of the leading causes of diplegic cerebral palsy is periventricular leukomalacia (PVL)—damage or death of the white matter in a baby’s brain. Understanding this connection is crucial for families seeking legal answers, as PVL often results from preventable complications.
What Is Periventricular Leukomalacia?
According to Cleveland Clinic, PVL is characterized by the softening or death of white matter tissue in the brain—the inner part that transmits information between nerve cells and the spinal cord. PVL is the predominant form of brain injury and the leading known cause of cerebral palsy in premature infants.
Critical Fact: Research shows that approximately 60-100% of infants diagnosed with periventricular leukomalacia will develop cerebral palsy, with spastic diplegia being the most common manifestation.
Why Premature Babies Are at Higher Risk
Babies born before 32 weeks of gestation face the highest risk of PVL because their brains are still developing and are more vulnerable to injury. The condition develops when insufficient blood or oxygen reaches the baby’s brain, either before or after birth.
Premature Birth
Development peaks between 24-32 weeks gestation when white matter is most vulnerable to oxygen deprivation
Low Birth Weight
Babies born small for gestational age have underdeveloped blood vessels and reduced brain protection
Maternal Infections
Untreated infections and ruptured amniotic sac increase inflammation and oxygen disruption
How PVL Leads to Spastic Diplegia
Cystic periventricular leukomalacia affects the deep and medial fiber tracts that control lower extremity functions. When these specific white matter areas are damaged, the result is typically spastic diplegia—tight, contracted muscles primarily in the legs. If more lateral fibers are affected, upper extremity function can also be impaired, potentially resulting in quadriplegia.
Diagnosing Diplegic Cerebral Palsy
Early and accurate diagnosis is essential for both medical treatment and legal documentation. Multiple diagnostic tools help identify diplegic cerebral palsy and determine its underlying cause.
Imaging Tests
| Test Type | Purpose | What It Shows | Best Timing |
|---|---|---|---|
| MRI (Magnetic Resonance Imaging) | Detailed brain structure analysis | White matter lesions, PVL, cortical abnormalities, timing of brain injury | After 2-3 weeks of life; preferred method |
| CT Scan | Cross-sectional brain images | Congenital malformations, bleeding, PVL (less detailed than MRI) | Early infancy; 15-20 minute procedure |
| Cranial Ultrasound | Initial screening in infants | Cysts or hollow areas in brain tissue from PVL | At birth and 4-8 weeks later for at-risk babies |
| EEG (Electroencephalogram) | Monitor brain electrical activity | Seizure activity and epilepsy signs | When seizures are suspected |
| EMG (Electromyogram) | Assess muscle and nerve function | How well muscles and nerves respond to signals | After motor symptoms appear |
According to medical research, MRI is the diagnostic study of choice for cerebral palsy because it defines cortical and white matter structures more clearly than any other method. Studies show that 89% of children with cerebral palsy have abnormal MRIs. In diplegic cases specifically, MRI often reveals bilateral lesions in subcortical regions or occipital periventricular areas—the signature pattern of PVL-related spastic diplegia.
Important Note: Some patients with clinical cerebral palsy have normal imaging results. Normal brain scans do not exclude a CP diagnosis, but in such cases, doctors should investigate other underlying metabolic or genetic causes.
Treatment Options for Spastic Diplegia
While periventricular leukomalacia and the resulting brain damage are permanent and cannot be cured, multiple treatments can significantly improve function, reduce spasticity, and enhance quality of life. The good news: PVL is not progressive—it will not worsen over time with proper management.
Early Intervention Is Critical
Children’s brains have greater plasticity (ability to adapt and form new connections) than adult brains, making early intervention crucial. Addressing spasticity early can replace abnormal movement patterns with proper habits before they become permanently ingrained. The optimal window for many interventions is between ages 2-5 years.
Physical and Occupational Therapy
Physical therapy is the cornerstone of spastic diplegia treatment. Most children with this condition benefit significantly from consistent therapy, which can:
- Loosen stiff muscles and improve flexibility
- Promote physical healing and overall wellness
- Address balance and posture issues
- Build stamina and muscle strength (especially in underused abductor muscles)
- Teach proper walking patterns to prevent scissoring gait
- Maintain range of motion and prevent contractures
Medications
Muscle Relaxants (Baclofen)
Oral medications help reduce muscle hyperactivity and provide temporary spasticity relief. Generally taken multiple times daily, these provide short-term management but do not address underlying issues.
Botox Injections
Botulinum toxin injections temporarily reduce spasticity by blocking nerve signals that cause muscles to contract. Effects typically last 3-6 months, requiring repeated treatments.
Orthotic Devices and Braces
Special devices help support proper leg alignment and prevent further muscle tightening:
- Ankle-foot orthoses (AFOs): Braces that stabilize the ankle and prevent toe walking
- SWASH orthoses: Special devices that keep legs parallel and prevent scissoring
- Splints: Maintain proper positioning during rest to prevent contractures
Surgical Interventions
When conservative treatments don’t yield sufficient results, surgical options may be recommended:
Adductor Lengthening Surgery
Surgical lengthening of the inner thigh muscles (hip adductors) can reduce scissoring gait by releasing the constant tension pulling the legs together. This procedure is often combined with physical therapy for optimal results.
Selective Dorsal Rhizotomy (SDR)
A neurosurgical procedure that permanently reduces spasticity by selectively cutting nerve fibers responsible for excessive muscle contraction. SDR is most effective for children ages 2-5 with good potential for functional gain, particularly those with hemiplegia or diplegia. The procedure offers permanent spasticity reduction and improved mobility.
When Diplegic Cerebral Palsy Constitutes Medical Malpractice
Not all cases of spastic diplegia result from medical negligence—some occur despite excellent medical care. However, when preventable errors during pregnancy, labor, or delivery cause the condition, it may constitute medical malpractice.
Understanding Preventable vs. Non-Preventable Cases
According to medical research, brain injury during pregnancy or childbirth accounts for 90% of cerebral palsy cases. When these injuries occur due to negligent care by healthcare providers, families have legal grounds to pursue compensation.
Key Distinction: The question is not whether your child has cerebral palsy, but whether proper medical care could have prevented it. If healthcare providers failed to meet the standard of care and that failure caused or contributed to your child’s condition, you may have a valid claim.
Common Forms of Medical Negligence
Medical malpractice cases involving diplegic cerebral palsy often involve one or more of the following failures:
During Pregnancy
- Failure to diagnose or treat maternal infections
- Improper management of preeclampsia or gestational hypertension
- Inadequate monitoring of high-risk pregnancies
- Failure to identify signs of premature labor
- Negligent use of medications that affect fetal development
During Labor & Delivery
- Failure to monitor fetal distress (abnormal heart rate patterns)
- Delayed C-section when emergency delivery is needed
- Improper use of forceps or vacuum extractors
- Allowing prolonged labor without intervention
- Failure to address prolapsed umbilical cord
- Mismanagement of shoulder dystocia
- Inadequate response to oxygen deprivation (hypoxia)
How Oxygen Deprivation Leads to PVL and Spastic Diplegia
Many of these negligent actions share a common outcome: oxygen deprivation to the baby’s developing brain. When brain tissue doesn’t receive adequate oxygen (hypoxia) or blood flow (ischemia), white matter damage occurs—particularly in the periventricular areas surrounding the brain’s fluid-filled ventricles. This damage manifests as PVL, which in turn causes the characteristic leg spasticity of diplegic cerebral palsy.
For premature babies, the risk is even higher. The white matter in their developing brains is especially vulnerable to oxygen fluctuations between 24-32 weeks of gestation. Medical staff caring for high-risk pregnancies must take extra precautions to prevent oxygen deprivation during this critical window.
New York Laws Governing Diplegic Cerebral Palsy Lawsuits
Understanding your legal rights under New York law is essential for protecting your child’s future. New York has specific statutes that govern medical malpractice claims involving birth injuries.
Statute of Limitations in New York
The statute of limitations sets a deadline for filing a lawsuit. In New York, cerebral palsy cases have special rules:
Standard Medical Malpractice
2.5 years from the date of negligence for adult patients
Minors (Birth Injuries)
10 years from the child’s date of birth to file on their behalf
Municipal Hospitals
Much shorter deadlines (as brief as 90 days for notice of claim)
Critical Warning: If your child was born in a municipal hospital (public hospital run by the city or county), you may have as little as 90 days to file a notice of claim. Do not assume you have 10 years—consult a qualified New York birth injury attorney immediately to determine your specific deadline.
No Damage Caps in New York
Unlike some states that limit compensation amounts, New York does not cap damages in medical malpractice cases. This means you can seek full compensation for all losses, including:
- Past and future medical expenses
- Lifetime care costs (approximately $1 million according to the CDC)
- Physical therapy, occupational therapy, and speech therapy
- Medications and medical equipment
- Surgical procedures (including SDR, muscle lengthening)
- Orthotic devices and mobility aids
- Home modifications for accessibility
- Special education costs
- Pain and suffering (both the child’s and parents’)
- Lost earning capacity over the child’s lifetime
You Have the Right to File Regardless of Uncertainty
You have the legal right to consult a cerebral palsy lawyer if your child has been diagnosed with spastic diplegia, regardless of individual symptoms or whether you’re certain malpractice occurred. An experienced attorney can:
- Review medical records to identify potential negligence
- Consult with medical experts who specialize in birth injuries
- Determine whether the standard of care was breached
- Establish the connection between negligence and your child’s injury
- Handle all legal proceedings while you focus on your child’s care
What Are Diplegic Cerebral Palsy Lawsuits Worth in New York?
Settlement and verdict amounts in cerebral palsy cases vary significantly based on the severity of the condition, the strength of the evidence, and the child’s projected lifetime needs. However, substantial compensation is possible in New York.
Recent Settlement Examples
| Year | Location | Amount | Case Details |
|---|---|---|---|
| 2023 | Pennsylvania | $182,737,791 | Delayed C-section and failure to treat maternal infection led to hypoxic-ischemic encephalopathy and spastic quadriplegic cerebral palsy |

| 2014 | Virginia | $5,550,000 | Continued Pitocin administration despite fetal distress instead of expediting delivery caused brain injury and cerebral palsy |
| Various | Philadelphia | $3,000,000 each | Multiple settlements for infants who developed cerebral palsy due to medical negligence during delivery |
Average Compensation Expectations
According to legal experts specializing in cerebral palsy cases:
- The average settlement for preventable cerebral palsy is over $1 million
- Experienced firms report securing around $2.5 million on average for clients affected by cerebral palsy
- Many New York cerebral palsy lawsuits are worth millions of dollars in damages due to no damage caps
Factors Affecting Settlement Value: Compensation amounts depend on the type and severity of CP, estimated lifetime medical costs, the child’s life expectancy, lost earning capacity, strength of evidence proving negligence, and geographic location (since laws vary by state).
Why Lifetime Costs Justify High Settlements
The CDC estimates that caring for a child with cerebral palsy costs almost $1 million over the child’s lifetime. This includes:
Direct Medical Costs
- Doctor visits and specialist consultations
- Physical, occupational, and speech therapy (ongoing)
- Medications and muscle relaxants
- Botox injections every 3-6 months
- Surgical procedures (SDR, muscle lengthening)
- Orthotic devices, braces, wheelchairs
- Assistive technology and communication devices
Indirect and Long-Term Costs
- Home modifications for accessibility
- Modified vehicles and transportation
- Special education services
- Adult care after age 18
- Lost wages for parents providing care
- Reduced lifetime earning capacity for the child
- Pain, suffering, and diminished quality of life
How to File a Diplegic Cerebral Palsy Lawsuit in New York
If you believe medical negligence caused your child’s spastic diplegia, follow these steps to protect your legal rights:
Step 1: Obtain Complete Medical Records
Request copies of all medical records related to pregnancy, labor, delivery, and your child’s neonatal care. These documents are essential evidence and should include:
- Prenatal care records and test results
- Fetal monitoring strips from labor and delivery
- Delivery room notes and operative reports (if C-section performed)
- Newborn intensive care unit (NICU) records
- Imaging results (MRI, CT, ultrasound)
- Diagnosis and treatment records for cerebral palsy
Step 2: Consult a Qualified New York Birth Injury Attorney
Do not attempt to navigate medical malpractice law alone. Birth injury cases require:
- Specialized legal expertise in medical malpractice and birth injury law
- Access to medical experts who can review records and testify
- Substantial financial resources to pursue complex litigation (costs can exceed $100,000)
- Experience with New York-specific laws and court procedures
No Upfront Costs: Reputable New York birth injury attorneys work on a contingency fee basis. This means you pay nothing unless they win your case. The attorney’s fee (typically 30-40%) comes from the settlement or verdict amount, not from your pocket.
Step 3: Case Investigation and Expert Review
Your attorney will:
- Conduct a thorough review of all medical records
- Consult with medical experts (obstetricians, neurologists, neonatologists)
- Determine whether the standard of care was breached
- Establish causation (linking the negligence to your child’s injury)
- Calculate the full value of your claim (past and future damages)
Step 4: Filing the Lawsuit
If experts confirm that malpractice occurred, your attorney will file a lawsuit in the appropriate New York court. The complaint will detail:
- The medical professionals and institutions being sued
- Specific acts of negligence that breached the standard of care
- How those negligent acts caused your child’s diplegic cerebral palsy
- The damages you’re seeking (economic and non-economic)
Step 5: Discovery, Negotiation, and Resolution
Most birth injury cases settle out of court through negotiation. The process typically involves:
- Discovery: Both sides exchange evidence, take depositions, and build their cases
- Mediation: A neutral third party helps facilitate settlement discussions
- Settlement Negotiation: Attorneys negotiate compensation on your behalf
- Trial (if necessary): If settlement cannot be reached, the case proceeds to trial
The timeline varies, but cerebral palsy cases often take 1-3 years to resolve due to their complexity.
Why Choose a Specialized Birth Injury Attorney
Birth injury cases involving diplegic cerebral palsy are among the most complex in medical malpractice law. Generic personal injury attorneys lack the specific expertise needed to:
Medical Expertise
Understand fetal monitoring strips, Apgar scores, PVL imaging, neurological development, and obstetric standards of care
Expert Networks
Access top medical experts willing to testify, including perinatologists, neurologists, and life care planners
Financial Resources
Invest $100,000+ in expert witnesses, medical record reviews, and litigation costs without upfront payment from you
Frequently Asked Questions About Diplegic Cerebral Palsy Lawsuits in NY
What is the difference between diplegic and other types of cerebral palsy?
Diplegic cerebral palsy (spastic diplegia) specifically affects both legs primarily, with the arms minimally affected or not affected at all. This contrasts with hemiplegic CP (affecting one side of the body), quadriplegic CP (affecting all four limbs), and monoplegic CP (affecting one limb). The “spastic” designation means muscles are stiff and tight rather than loose or uncontrolled. Diplegic CP is the most common result of periventricular leukomalacia (PVL) in premature infants.
Can diplegic cerebral palsy be prevented?
While not all cases are preventable, many instances of spastic diplegia result from preventable medical errors. Proper monitoring during pregnancy and delivery, timely intervention when fetal distress occurs, appropriate management of maternal infections, and rapid response to oxygen deprivation can prevent the brain damage that leads to PVL and subsequent diplegic CP. Studies indicate that up to 90% of cerebral palsy cases involve brain injury during pregnancy or childbirth—many of which could have been avoided with proper medical care.
How long do I have to file a cerebral palsy lawsuit in New York?
In New York, the statute of limitations for birth injury cases involving minors is generally 10 years from the child’s date of birth. However, there are critical exceptions: if your child was born in a municipal hospital (city or county-run facility), you may have as little as 90 days to file a notice of claim. The statute of limitations has many nuances, and missing the deadline means losing your right to compensation forever. Consult a qualified New York birth injury attorney immediately to determine your specific filing deadline.
What is periventricular leukomalacia (PVL) and why does it cause leg problems?
Periventricular leukomalacia (PVL) is damage to the white matter of the brain surrounding the fluid-filled ventricles. This white matter contains nerve fibers that transmit signals between the brain and body. When PVL occurs, it specifically affects the deep and medial fiber tracts that control the lower extremities (legs). Because these control pathways are damaged, children develop spastic diplegia—tight, contracted leg muscles with scissoring gait. PVL is the leading cause of cerebral palsy in premature infants and results from oxygen deprivation to the developing brain.
What is scissoring gait and can it be treated?
Scissoring gait is a characteristic walking pattern where the legs cross at the knees with each step, resembling the motion of scissors. It’s caused by excessive muscle tone (spasticity) in the hip adductor muscles, which pull the thighs together involuntarily. While the gait pattern itself cannot be “cured,” it can be significantly improved through physical therapy, Botox injections to relax tight muscles, orthotic devices like SWASH orthoses that keep legs parallel, and surgical interventions such as adductor lengthening or selective dorsal rhizotomy. Early intervention yields the best results due to childhood brain plasticity.
How much is a diplegic cerebral palsy lawsuit worth in New York?
Settlement values vary widely based on severity, evidence strength, and lifetime care needs. However, averages provide guidance: most preventable cerebral palsy settlements exceed $1 million, with specialized firms reporting averages around $2.5 million. Recent verdicts range from $1 million to over $180 million, with the highest awards going to the most severe cases involving quadriplegia. New York does not cap damages, so you can seek full compensation for all medical expenses, future care costs (approximately $1 million lifetime according to the CDC), pain and suffering, and lost earning capacity.
Will I have to pay upfront costs to hire a birth injury lawyer?
No. Reputable New York birth injury attorneys work on a contingency fee basis, meaning you pay nothing upfront and nothing unless you win. The attorney advances all costs for medical record reviews, expert witnesses (often $100,000+), court filing fees, and litigation expenses. If the case is successful, the attorney’s fee (typically 30-40% of the recovery) and costs are deducted from the settlement or verdict. If the case is unsuccessful, you owe nothing. This arrangement ensures all families have access to justice regardless of financial means.
Can adults with diplegic cerebral palsy file a lawsuit for birth injuries?
In New York, the 10-year statute of limitations for minors begins at birth. Once the child turns 10 years old, the standard 2.5-year medical malpractice statute applies, meaning the lawsuit must typically be filed before the child’s 12th or 13th birthday. However, there are exceptions for cases involving continuous treatment, fraudulent concealment, or discovery of new evidence. Additionally, in some jurisdictions, individuals with disabilities may qualify for extensions under “disability tolling” provisions. Adults with diplegic cerebral palsy who never pursued a claim should consult an attorney immediately, as narrow exceptions may still apply.
What evidence is needed to prove medical malpractice in diplegic cerebral palsy cases?
Strong cerebral palsy cases require: (1) Medical records showing substandard care (delayed C-section, ignored fetal distress, improper use of instruments); (2) Fetal monitoring strips documenting abnormal heart rate patterns that should have prompted intervention; (3) Expert testimony from obstetricians, neurologists, and neonatologists establishing what proper care should have been; (4) Imaging evidence (MRI showing PVL consistent with oxygen deprivation); (5) Causation evidence linking the timing of negligence to the timing of brain injury; and (6) Life care plans documenting future medical needs and costs.
What if doctors say my child’s cerebral palsy was unavoidable?
Healthcare providers have an incentive to characterize all cerebral palsy cases as unavoidable to avoid liability. Do not simply accept this assertion. Seek a second opinion from an independent medical expert through a qualified birth injury attorney. Many cases initially dismissed as “unavoidable” are actually the result of clear negligence when reviewed by specialists. An independent review of fetal monitoring strips, delivery timing, and medical decision-making can reveal substandard care that led to preventable oxygen deprivation and PVL. You have the legal right to have your case evaluated regardless of what the original medical team claims.
