Erb's Palsy & Brachial Plexus Injury Lawyer New York

The Brachial Plexus Anatomy

To understand how Erb's Palsy occurs, you need to understand the brachial plexus — a bundle of nerves originating at the spinal cord in the lower neck (nerve roots C5, C6, C7, C8, and T1) that branches out to control the muscles of the shoulder, arm, wrist, and hand.

Think of the brachial plexus as a telephone cable carrying signals from the brain to the arm. When that cable is stretched too far, the individual nerve fibers within it can be damaged — much like wires inside a cable can fray or snap even if the outer sheath remains intact.

There are several types of nerve injury, classified by severity:

• Neurapraxia (stretch injury): The nerve is stretched but not torn. This is the mildest form and typically heals on its own within weeks to months.
• Neuroma (scar tissue injury): The nerve has been partially torn and healed with scar tissue, which can interfere with signal transmission. Some recovery is possible, but not always complete.
• Rupture (nerve tear): The nerve is torn but remains attached to the spinal cord. This will not heal on its own and typically requires surgical repair.
• Avulsion (nerve root separation): The most severe form — the nerve root is completely torn away from the spinal cord. This is permanent and may require nerve transfer surgery.

How Erb's Palsy Happens During Childbirth

Known Risk Factors That Should Trigger Preparation

Erb's Palsy overwhelmingly occurs during vaginal delivery, and the mechanism is almost always the same: excessive lateral traction on the baby's head and neck during a difficult delivery, which stretches the brachial plexus nerves beyond their physiological limit.

Here is what typically happens:

1. The baby's head delivers, but one or both shoulders become stuck behind the mother's pubic bone — a condition called shoulder dystocia. 2. The delivering physician or midwife applies traction — pulling force — to the baby's head to dislodge the stuck shoulder. 3. If the traction is excessive or improperly directed, the neck bends laterally, stretching the brachial plexus on the opposite side. 4. The nerves stretch, tear, or avulse, resulting in Erb's Palsy.

The critical question in any Erb's Palsy malpractice case is not whether shoulder dystocia occurred — that can happen even with excellent care. The question is whether the response to the shoulder dystocia met the accepted standard of care.

Shoulder Dystocia: The Leading Cause

Shoulder dystocia is an obstetric emergency where, after the baby's head is delivered, the anterior shoulder becomes impacted behind the mother's symphysis pubis. It occurs in approximately 0.2% to 3% of vaginal deliveries. While not always preventable, the response to shoulder dystocia is where malpractice most often occurs.

The standard of care requires the delivery team to follow a specific sequence of recognized maneuvers to free the impacted shoulder without applying excessive traction:

• McRoberts Maneuver: Hyperflexing the mother's hips toward her abdomen to flatten the sacrum and rotate the symphysis pubis, opening the pelvic outlet. First-line maneuver.
• Suprapubic Pressure: Applying pressure above the pubic bone to push the anterior shoulder free, combined with McRoberts.
• Rubin Maneuver: Rotating the baby's shoulders internally to reduce the bisacromial diameter.
• Woods' Corkscrew Maneuver: Rotating the posterior shoulder 180 degrees to deliver it first.
• Delivery of the Posterior Arm: Reaching in to deliver the posterior arm first, which reduces the shoulder diameter.
• Last-Resort Maneuvers: Intentional clavicle fracture, symphysiotomy, or the Zavanelli maneuver (replacing the head and performing emergency C-section).

The Critical Rule: No Excessive Traction

The one principle running through all of these maneuvers is this: fundal pressure (pushing on the top of the uterus) and excessive traction on the baby's head are never appropriate. They are the two interventions most likely to cause brachial plexus injury.

If a delivery record shows that the physician pulled hard on the baby's head, used fundal pressure, or failed to attempt recognized maneuvers before resorting to force, that is strong evidence of negligence.

Signs and Symptoms

Parents are often the first to notice that something is wrong. If your newborn shows any of the following signs, Erb's Palsy may be the underlying cause:

• The affected arm hangs limply at the side or is rotated inward
• The baby cannot raise the arm or bring the hand to the mouth
• The 'waiter's tip' posture: arm extended, internally rotated, wrist flexed with fingers facing backward
• Lack of Moro reflex (startle reflex) on the affected side
• Asymmetric movement: the unaffected arm moves normally while the affected arm remains still
• Poor grip or inability to flex fingers on the affected hand (if lower nerves are involved)
• Horner's syndrome (drooping eyelid, constricted pupil) on the affected side, indicating a more severe avulsion injury

Diagnosing and Classifying the Injury

Proper diagnosis of Erb's Palsy involves multiple specialists and imaging studies:

• Physical examination: A pediatrician or neurologist assesses muscle tone, reflexes, and range of motion in the affected arm.
• Imaging: MRI or CT myelography can identify nerve root avulsions — pseudomeningoceles (fluid-filled cysts) at the nerve root level are a hallmark sign of avulsion.
• Electrodiagnostic studies: EMG and nerve conduction studies assess whether nerve signals are reaching the muscles and help distinguish between neurapraxia, rupture, and avulsion.
• Surgical consultation: If there is no spontaneous recovery by 3-6 months of age, surgical intervention (nerve grafting, nerve transfer, or neuroma excision) may be recommended by a brachial plexus specialist.

When Is Erb's Palsy Medical Malpractice?

Common Breaches in Erb's Palsy Cases

Not every Erb's Palsy case is malpractice. Some brachial plexus injuries occur even when the physician does everything right. However, Erb's Palsy constitutes medical malpractice when the delivering provider deviated from the accepted standard of care and that deviation caused the injury.

Under New York law, medical malpractice requires proof of four elements:

1. Duty of care: The physician owed a duty to the patient (established by the doctor-patient relationship). 2. Breach of duty: The physician deviated from the accepted standard of care — what a reasonably prudent physician in the same specialty would have done. 3. Causation: The breach directly caused the injury. 4. Damages: The injury resulted in measurable harm (physical, emotional, financial).

• Failure to identify risk factors for shoulder dystocia (macrosomia, diabetes, prior dystocia)
• Failure to recommend a planned C-section when risk factors strongly predicted shoulder dystocia
• Excessive traction or pulling on the baby's head during delivery
• Use of fundal pressure instead of recognized maneuvers
• Failure to perform or properly execute the McRoberts maneuver and suprapubic pressure
• Failure to call for assistance (additional physicians, anesthesia) when shoulder dystocia was identified
• Inadequate documentation of the maneuvers attempted and the time taken

The Standard of Care for Shoulder Dystocia

Under New York law, the standard of care is defined by what a reasonably competent obstetrician would have done under the same or similar circumstances. This standard is established through expert testimony — typically a board-certified obstetrician who reviews the medical records and testifies about what should have been done.

At MDLaw Firm, we work with leading obstetric experts, maternal-fetal medicine specialists, and pediatric neurologists to build a clear, evidence-based case that the standard of care was breached. We obtain and review prenatal records, labor and delivery records, operative reports, pediatric and neurology records, and hospital policies and protocols.

Common Defense Arguments and How We Counter Them

"Shoulder dystocia is unpredictable and unavoidable."

Insurance companies and defense attorneys in New York have a playbook for defending Erb's Palsy cases. Here are the most common arguments they raise, and how we counter them:

• Our Counter: While shoulder dystocia can be unpredictable, the risk factors are well-known and documented. If the medical team failed to identify clear risk factors — such as fetal macrosomia or maternal diabetes — or failed to prepare for a known risk, the injury was preventable.

Defense: "The injury occurred in utero, not during delivery."

Our Counter: This is a common defense that claims the brachial plexus was injured before labor began. We counter this with electrodiagnostic studies, imaging, and the timing of symptom onset. True in utero injuries are rare and have distinct clinical patterns that differ from traction injuries.

Defense: "We used appropriate maneuvers and the injury still occurred."

Our Counter: We obtain the complete delivery records and have our obstetric experts analyze the documented maneuvers. If the records show excessive traction, fundal pressure, or a failure to attempt standard maneuvers, the defense collapses.

Defense: "The injury is minor and will resolve on its own."

Our Counter: We do not accept this defense without independent medical evaluation. We work with pediatric neurologists to assess the true extent of the injury. If the injury involves rupture or avulsion, it will not resolve on its own — and we fight for the full, lifelong cost of care.

New York Statute of Limitations for Birth Injuries

This is one of the most critical things to understand: "Is it too late to file a claim?"

Under New York's Civil Practice Law and Rules (CPLR § 214-a), the general statute of limitations for medical malpractice is 2 years and 6 months from the date of the malpractice. However, there is a crucial exception for minors.

Under CPLR § 208, the statute of limitations is tolled (paused) for minors until they reach the age of 18. This means the child has until their 20th birthday (18 + 2.5 years) to file a medical malpractice claim on their own behalf.

However, a parent's derivative claim for medical expenses is subject to the standard 2.5-year limitation and is NOT tolled. This means that even if your child is several years old, they may still have a valid claim — but your right to recover medical expenses may have expired. Contact a lawyer as early as possible to preserve all claims.

Compensation Available in Erb's Palsy Cases

Economic Damages

A successful Erb's Palsy malpractice claim in New York can provide compensation for both economic and non-economic damages:

• Past and future medical expenses (surgeries, physical therapy, occupational therapy, nerve grafting)
• Rehabilitation and assistive devices (braces, splints, adaptive equipment)
• Lost earning capacity (if the injury affects future ability to work)
• Special education and tutoring (if developmental delays result from associated injuries)
• Home modifications (if the disability affects mobility or independence)

Non-Economic Damages

What to Expect Working with MDLaw Firm

New York does not cap non-economic damages in medical malpractice cases. This means there is no arbitrary ceiling on the compensation a jury can award for pain and suffering — each case is evaluated on its individual merits.

New York also requires medical malpractice cases to go through a certificate of merit (CPLR § 3012-a), confirming that a qualified medical professional has reviewed the case and found it meritorious. At MDLaw Firm, we handle this requirement as part of our standard case preparation.

• Free Initial Consultation: We listen to your story, review basic facts, and explain your legal rights — at no cost or obligation.
• Medical Record Review: With your authorization, we obtain all relevant medical records — prenatal, delivery, pediatric, and neurology.
• Expert Review: We engage board-certified obstetric and neurological experts to evaluate whether the standard of care was breached.
• Case Filing: If we determine you have a valid claim, we file within the applicable statute of limitations.
• Discovery and Litigation: We conduct depositions, obtain additional evidence, and build the strongest possible case.
• Resolution: We pursue the maximum compensation available — through settlement negotiation or trial.
