The brachial plexus is the bundle of nerves running from the neck through the shoulder that controls the arm and hand. When it is stretched or torn during birth, the result can be weakness or paralysis in that arm, known as Erb's palsy when the upper nerves are affected.
Many of these injuries recover substantially in the first months. Some do not, and a child is left with a permanently weaker, shorter or less functional arm. The legal question is not whether the emergency happened — it is what was done when it did.
Shoulder dystocia, and the response that matters
Shoulder dystocia occurs when a baby's head delivers but a shoulder becomes caught behind the mother's pelvic bone. It is unpredictable, it cannot reliably be prevented, and it is a genuine emergency — nobody is blamed for it happening.
What obstetric teams are trained to do is respond with a recognized sequence of maneuvers designed to free the shoulder without pulling on the baby's head and neck: repositioning the mother's legs, applying pressure above the pubic bone, internal rotational maneuvers, and delivering the posterior arm.
The claim usually concerns traction. Where excessive lateral traction is applied to the head and neck instead of, or as well as, those maneuvers, the brachial plexus takes the force. That is the distinction between an unavoidable emergency and a departure from the standard of care.
Risk factors that should have been recognized
Dystocia cannot be predicted reliably, but risk can be assessed, and the assessment shapes what a reasonable plan for the delivery looked like:
- A large estimated fetal weight, and how that estimate was arrived at
- Maternal diabetes, including gestational diabetes, and how well it was controlled
- A previous shoulder dystocia in an earlier delivery
- Prolonged second stage of labor, and a labor that was not progressing
- Instrumental delivery, by forceps or vacuum
- Excessive maternal weight gain, or a post-term pregnancy
Where several of these were present and none of them changed the plan or the counseling given to the mother, that is part of the case too.
What the injury involves
The severity depends on how badly the nerves were damaged: stretched nerves often recover, while nerves that are torn, or pulled from the spinal cord itself, generally do not recover without surgery and sometimes not with it.
- Erb's palsy, affecting the upper nerves, with the characteristic weakness of the shoulder and upper arm
- Klumpke's palsy, affecting the lower nerves, with the hand more involved
- Global involvement, where the whole arm is affected
- Associated injuries, including fractures of the collarbone or upper arm sustained during the same delivery
Treatment usually begins with physiotherapy and occupational therapy. Where recovery stalls, nerve graft or transfer surgery may be considered, and the timing of that decision matters — which is why a delayed referral to a specialist center is sometimes part of a claim in its own right. Later surgery may address tendon and muscle function. Chronic nerve pain can persist regardless.
How these claims are proven
- The delivery record, particularly the account of the dystocia: how long the head-to-body interval was, which maneuvers were used, in what order, and by whom.
- Who was present, and when senior help was called.
- The antenatal record, including growth estimates, diabetes management and what was discussed about mode of delivery.
- The newborn examination, and when the arm weakness was first noted.
- The subsequent course, including referral timing and what function was recovered.
- Expert evidence from obstetrics on whether the response met the standard, and from pediatric neurology or surgery on causation and prognosis.
Maryland requires a certificate from a qualifying expert before the claim proceeds, and it is filed with the state health care dispute office first, as with any medical malpractice claim.
How long families have
Malpractice claims generally run five years from the injury or three years from discovery, whichever comes first, and claims on behalf of a child follow their own rules, which can extend the time available.
Families frequently wait to see how much function returns, which is entirely reasonable and can mean years pass before anyone thinks about a claim. That is a normal way for these cases to start, and it is worth asking rather than assuming the time has gone.
