Watching your newborn come into the world should be one of the most joyful moments of your life. But when something goes wrong during delivery and your baby is diagnosed with a nerve injury, that joy turns into fear, confusion, and a lot of unanswered questions. Klumpke's palsy is one of those injuries that often leaves families wondering whether what happened was just an unfortunate complication or something that could have been prevented. This article is here to help you understand what Klumpke's palsy is, how it happens, and what it actually takes to have a valid legal claim.

Quick Checklist: Do You Have Grounds for a Lawsuit?
Before diving into the details, here's a simple checklist to help you get an early sense of whether your situation warrants a closer legal look. This is not a substitute for speaking with an attorney, but it gives you a starting point.
- Your child has been diagnosed with Klumpke's palsy or a lower brachial plexus injury by a doctor or specialist
- The delivery involved complications like shoulder dystocia, high birth weight, forceps or vacuum use, or a difficult emergency C-section
- You remember or the records reflect that the medical team pulled forcefully on the baby's head or neck during delivery
- Your child has lasting weakness, limited hand or arm function, or requires ongoing therapy or surgery related to the injury
- The injury occurred within the last 10 years (New York's legal deadline for birth injury malpractice cases involving minors)
If most of these apply to your situation, there is a real possibility that you have a Klumpke's palsy lawsuit worth exploring with a qualified attorney.
What Is Klumpke's Palsy?
Klumpke's palsy is a specific type of brachial plexus birth injury affecting the lower nerve roots of the arm, known as C8 and T1. The brachial plexus is the network of nerves running from the spinal cord through the neck and into the arm, and when those nerves are damaged during delivery, the effects can range from temporary weakness to permanent paralysis. Klumpke's palsy specifically impacts the lower portion of that nerve network, which controls the forearm and hand. This means babies with the condition often have trouble gripping, moving their fingers, or fully using their hand on the affected side. In some cases, it also causes a condition called Horner syndrome, where the eyelid droops slightly and the pupil appears smaller on the same side as the injury.
It is worth knowing that Klumpke's palsy is actually rarer than Erb's palsy, which is the more commonly discussed brachial plexus birth injury. Erb's palsy affects the upper nerve roots and causes the classic "waiter's tip" arm position. Klumpke's is more specifically a hand and forearm issue, and it shows up in less than 10% of all brachial plexus birth injuries. The injury is typically visible right after birth, when the baby does not move the affected hand normally or does not demonstrate a normal grasp reflex. Parents often notice it first, and it usually gets confirmed through a physical exam and imaging or nerve conduction studies.
How Does This Injury Happen During Birth?
The most common cause of brachial plexus birth injuries is something called shoulder dystocia, which is when the baby's shoulder becomes stuck behind the mother's pubic bone during delivery. When this happens, the delivery suddenly becomes an emergency. The medical team needs to act quickly to free the shoulder, and the techniques they use in those moments matter enormously. If the provider pulls too hard or at the wrong angle on the baby's head or neck, the nerves of the brachial plexus can be stretched, torn, or even avulsed from the spinal cord entirely.
Certain pregnancies carry a higher risk of this happening. Babies with macrosomia, meaning they are significantly larger than average (often over 4 to 4.5 kilograms), are more likely to experience shoulder dystocia. Mothers with diabetes, obesity, or excessive gestational weight gain are also in a higher risk category, as are labors that are prolonged or require the use of forceps or a vacuum device. In some cases, Klumpke's palsy has even been documented following Cesarean deliveries, particularly when the extraction was difficult or the baby was in an unusual position. The injury is not exclusive to vaginal deliveries, which surprises many families.
Does a Birth Injury Always Mean Someone Made a Mistake?
This is one of the most important things to understand before pursuing a Klumpke's palsy lawsuit. Not every birth injury is the result of negligence. ACOG, the American College of Obstetricians and Gynecologists, acknowledges that brachial plexus injuries can occur even when a provider does everything correctly. Shoulder dystocia can happen suddenly and without warning, and some degree of traction is inherently involved in managing it. The question is not simply whether your baby was hurt, but whether the care provided fell below accepted medical standards.
Think of it this way. Imagine two different deliveries, both involving shoulder dystocia. In one, the OB immediately calls for help, positions the mother in the McRoberts position, applies suprapubic pressure, and carefully works through the appropriate sequence of maneuvers. In the other, the provider panics, pulls hard on the baby's head without attempting proper maneuvers, and ignores documented warnings about fetal size from earlier in the pregnancy. Both deliveries may result in the same injury, but only one involves conduct that a medical expert could point to as a departure from standard care. That distinction is what separates a tragic complication from a malpractice case.
What Does "Standard of Care" Actually Mean in These Cases?
In medical malpractice law, the standard of care refers to what a reasonably competent provider in the same specialty would have done under the same circumstances. For obstetric care, this standard is shaped by guidelines from ACOG, hospital protocols, and the accumulated judgment of experienced practitioners. When it comes to shoulder dystocia, the standard includes recognizing risk factors during prenatal care, having a plan in place for high-risk deliveries, and executing a specific sequence of maneuvers during an emergency rather than resorting to excessive force.
Training and simulation programs specifically designed to prepare providers for shoulder dystocia emergencies have been shown to help reduce brachial plexus palsy rates, which tells us something important. The injury is not purely a matter of bad luck. It is, at least in part, a matter of skill, preparation, and adherence to protocols. When a provider fails to recognize that a baby is measuring large on ultrasound and does not document that in any delivery plan, or when forceps are applied incorrectly in a difficult delivery, those are the kinds of failures that can form the basis of a legal claim.
What Records Matter in a Klumpke's Palsy Case?
Medical records are the backbone of any birth injury case. The most critical documents include prenatal records showing whether risk factors like macrosomia or gestational diabetes were identified and documented, labor and delivery notes that capture how shoulder dystocia was recognized and managed, nursing notes reflecting the sequence of events in real time, and the newborn's physical exam findings shortly after birth. The delivery summary in particular often contains language about how traction was applied and what maneuvers were attempted.
If you are building a case, birth injury attorneys typically work with medical experts to comb through those records looking for specific red flags. Was the fundal height measuring large throughout the third trimester? Was a growth ultrasound ordered? When shoulder dystocia was identified, how quickly did the team respond and what exactly did they do? Were forceps or vacuum used, and if so, was there documentation of appropriate indication? These are the kinds of questions that can reveal whether what happened to your child was within the range of acceptable care or whether it crossed the line into negligence.
The Four Legal Elements You Need to Prove
To have a viable medical malpractice claim in New York, four things need to be established.
- First, there must be a duty of care, which exists automatically once a provider takes on a patient.
- Second, there must be a breach of that duty, meaning the provider deviated from accepted medical standards in a specific, demonstrable way.
- Third, that breach must have caused your child's injury, not just coincided with it.
- Fourth, your child must have suffered real, measurable damages as a result.
Causation is often the hardest element to establish in brachial plexus cases because the defense will typically argue that the injury would have occurred regardless of the technique used. This is why expert witnesses are so important. A pediatric neurologist or obstetric specialist who can testify that the injury pattern is consistent with excessive traction and not with unavoidable birth forces can be the difference between a strong case and a dismissed one. Damages in these cases can include the cost of surgeries like nerve grafting, years of physical and occupational therapy, adaptive equipment, and the longer-term impact on the child's ability to perform fine motor tasks, pursue certain careers, or fully participate in everyday activities.
How Long Do You Have to File a Lawsuit in New York?
New York's standard statute of limitations for medical malpractice is two and a half years from the date of the act or the end of continuous treatment for the same condition. For children, the law provides what is called infancy tolling under CPLR Section 208, which extends the filing window because the injured person is a minor. However, in medical malpractice cases, that extension is capped. Families generally have no more than 10 years from the date of the birth injury to file, regardless of the child's age.
This surprises a lot of families who assume they have until the child turns 18. The 10-year cap means that if your child was injured at birth, the clock is running, and consulting with an attorney sooner rather than later is genuinely important. Evidence can be harder to gather as time passes, witnesses' memories fade, and medical staff may no longer be available. If you are reading this with a young child who was diagnosed shortly after birth, do not let that deadline sneak up on you.
What a Klumpke's Palsy Lawsuit Actually Looks Like
When a family pursues a Klumpke's palsy lawsuit, it typically begins with a review of all medical records by both the attorney and a qualified medical expert. If the expert identifies deviations from the standard of care and can connect those deviations to the child's injury, the case moves forward with a formal filing. New York requires that malpractice cases be filed with a certificate of merit, which is a statement from the attorney confirming that a licensed medical professional has reviewed the claim and found it to have merit.
After filing, the case enters a discovery period where both sides exchange records, take depositions, and retain expert witnesses. Many of these cases settle before trial, but not all. A settlement means the family receives compensation without going through a jury trial, while a verdict after trial can result in a higher award or no award at all depending on how the jury weighs the expert testimony. What matters most in the early stages is the quality of the investigation and whether the evidence genuinely supports a departure from standard care that caused lasting harm.
