Shoulder Dystocia Malpractice in New York: Legal Rights for Parents

How Shoulder Dystocia Causes Birth Injury

When the baby's shoulder is stuck behind the pubic bone, the natural instinct of an untrained or panicked provider is to pull on the baby's head. This is exactly the wrong response.

The brachial plexus nerves (C5-T1) travel from the spinal cord through the neck and into the arm. When the head is pulled laterally (sideways) while the shoulder remains stuck, these nerves are stretched — sometimes to the point of tearing or complete avulsion from the spinal cord.

The severity of the nerve injury depends on the force applied and the duration of the stretching:

- Neurapraxia: The nerve is stretched but not torn. May heal within 3-6 months. - Neuroma: The nerve is partially torn and heals with scar tissue, which may permanently impair function. - Rupture: The nerve is torn but still attached to the spinal cord. Requires surgical repair. - Avulsion: The nerve root is ripped from the spinal cord. This is permanent and may require nerve transfer surgery.

The single most important factor in preventing these injuries is avoiding excessive traction and instead using the recognized shoulder dystocia maneuvers that widen the pelvic outlet and reposition the baby.

Risk Factors Every Obstetrician Should Recognize

New York obstetricians are trained to identify risk factors for shoulder dystocia. When these are present, the standard of care requires counseling the mother about the risks and, in many cases, recommending a planned cesarean section. Key risk factors include:

• Fetal macrosomia: Estimated fetal weight above 4,500 grams (9 lbs 15 oz) significantly increases risk. Ultrasound estimates of fetal weight in the third trimester should trigger discussion of delivery mode.
• Maternal diabetes: Diabetic mothers produce larger babies with disproportionate shoulder-to-head ratios (the shoulders are disproportionately large relative to the head, making impaction more likely).
• Prior shoulder dystocia: A history of shoulder dystocia in a previous delivery increases recurrence risk to approximately 10-15%.
• Prolonged second stage of labor: Extended pushing phases may indicate cephalopelvic disproportion.
• Post-term pregnancy: Deliveries beyond 40 weeks are associated with larger babies.
• Maternal obesity: BMI above 30 increases risk.
• Instrumental delivery: Use of forceps or vacuum extraction increases the risk of shoulder dystocia.
• Excessive maternal weight gain: During pregnancy, particularly in diabetic patients.

The Standard of Care: Recognized Maneuvers

When shoulder dystocia is identified, the standard of care requires the delivery team to follow a sequence of recognized maneuvers. The goal is to free the impacted shoulder without applying traction to the baby's head. The standard sequence includes:

• McRoberts Maneuver (first-line): Hyperflexing the mother's hips toward her abdomen, flattening the lumbar spine and rotating the symphysis pubis anteriorly. This widens the pelvic outlet and often frees the shoulder without any traction on the baby.
• Suprapubic Pressure (combined with McRoberts): An assistant applies pressure above the pubic bone (never fundal pressure on the top of the uterus) to push the anterior shoulder from behind the bone. The pressure is applied in a specific direction — typically laterally and posteriorly.
• Rubin Maneuver: The provider internally rotates the posterior shoulder to reduce the bisacromial diameter.
• Woods' Corkscrew Maneuver: Rotating the posterior shoulder 180 degrees to deliver it as the anterior shoulder.
• Delivery of the Posterior Arm: The provider reaches in and delivers the posterior arm first, which reduces the shoulder diameter and allows delivery.
• Last-Resort Maneuvers: Intentional clavicle fracture (to reduce shoulder width), symphysiotomy, or the Zavanelli maneuver (replacing the fetal head in the vagina and performing an emergency C-section).

When Shoulder Dystocia Becomes Medical Malpractice

Shoulder dystocia becomes medical malpractice when the delivering provider's actions — or inactions — deviate from the accepted standard of care and cause injury. Common breaches include:

• Excessive head traction: Pulling forcefully on the baby's head is the single most common cause of brachial plexus injury. The standard of care prohibits traction as a primary maneuver for resolving shoulder dystocia.
• Fundal pressure: Pushing on the top of the uterus is never appropriate for shoulder dystocia and increases the risk of both brachial plexus injury and uterine rupture.
• Failure to attempt recognized maneuvers: If the delivery record shows that the physician resorted to traction without first attempting McRoberts and suprapubic pressure, this is a deviation from the standard of care.
• Failure to recognize risk factors: If prenatal records show clear risk factors (macrosomia, diabetes, prior dystocia) that were not addressed through counseling or delivery planning, this may constitute negligence.
• Failure to call for help: Shoulder dystocia requires a team response. If the physician did not call for additional nursing staff, a second physician, or anesthesia, this may constitute a breach.
• Inadequate documentation: While poor documentation alone is not malpractice, it often accompanies poor care and makes it easier to prove negligence.

Injuries Caused by Shoulder Dystocia

Shoulder dystocia can cause a range of injuries to the newborn, depending on the force applied and the duration of impaction:

• Brachial plexus injury (Erb's Palsy): The most common injury — stretching or tearing of the nerves controlling the arm. Severity ranges from temporary weakness to permanent paralysis.
• Klumpke's Palsy: Injury to the lower brachial plexus nerves (C8-T1), affecting the hand and wrist. Results in a 'claw hand' deformity.
• Clavicle fracture: The collarbone may fracture during delivery, particularly if the physician applies excessive force or intentionally fractures it as a last-resort maneuver.
• Humeral fracture: The upper arm bone may fracture, particularly with rotational maneuvers.
• Hypoxic-ischemic encephalopathy (HIE): If the shoulder dystocia is prolonged and the umbilical cord is compressed, the baby may suffer oxygen deprivation leading to brain injury.
• Asphyxia and death: In the most severe cases, prolonged shoulder dystocia can cause fetal death from cord compression and asphyxia.

Diagnosing and Documenting the Injury

Proper evaluation of a shoulder dystocia injury involves multiple specialists:

- Pediatric examination: Assessment of arm movement, muscle tone, reflexes, and the presence of the classic 'waiter's tip' posture of Erb's Palsy. - Imaging studies: MRI or CT myelography to identify nerve root avulsions. - Electrodiagnostic testing: EMG and nerve conduction studies to assess nerve function and distinguish between stretch injuries and ruptures/avulsions. - Surgical consultation: If no recovery is seen by 3-6 months, evaluation by a brachial plexus surgeon for potential nerve grafting or transfer.

The delivery record itself is critical evidence. We look for documentation of: - The maneuvers attempted (McRoberts, suprapubic pressure, Rubin, Woods, posterior arm) - Whether fundal pressure was used - The time from head delivery to full delivery - Whether assistance was called - Apgar scores and cord blood gases - Any mention of traction or force applied to the head

Building a Shoulder Dystocia Malpractice Case

At MDLaw Firm, we build shoulder dystocia cases through a systematic, evidence-based approach:

1. Medical record collection: We obtain all prenatal, labor and delivery, pediatric, and neurology records. 2. Expert review: We engage board-certified obstetricians to evaluate whether the standard of care was breached. 3. Causation analysis: We work with pediatric neurologists to establish that the nerve injury was caused by the delivery, not by an in utero event. 4. Damages calculation: We work with lifecare planners and economists to quantify the full cost of the injury over the child's lifetime. 5. Litigation: We file the case, conduct discovery, take depositions, and prepare for trial — while remaining open to fair settlement.

We handle shoulder dystocia cases on a contingency fee basis — you pay nothing unless we secure compensation for your family.

Common Defense Strategies

Defense attorneys in shoulder dystocia cases typically argue:

• 'Shoulder dystocia is unpredictable.' We counter by showing that risk factors were identifiable and should have prompted preparation or C-section recommendation.
• 'The injury occurred in utero.' We counter with electrodiagnostic studies and imaging that distinguish traction injuries from in utero injuries.
• 'We used appropriate maneuvers.' We counter with the delivery record, which often documents excessive traction, fundal pressure, or failure to attempt standard maneuvers.
• 'The injury is minor and will resolve.' We counter with independent neurological evaluation and, if necessary, surgical consultation to document the true extent of the injury.

New York Legal Standards and Statute of Limitations

Under New York's CPLR § 214-a, the general statute of limitations for medical malpractice is 2.5 years. However, under CPLR § 208 (the infant tolling rule), the statute is tolled for minors until age 18, meaning the injured child has until approximately age 20 to file a claim on their own.

A parent's derivative claim for medical expenses is subject to the standard 2.5-year deadline and is not tolled. New York requires a certificate of merit (CPLR § 3012-a) confirming that a qualified medical professional has reviewed the case. New York does not cap non-economic damages in medical malpractice cases.
