What is an infant skull fracture?
An infant skull fracture is a break or crack in one of the bones of a baby’s skull, most often caused by pressure or trauma to the head during a difficult delivery. A newborn’s skull is not a single solid dome; it is several soft, flexible bony plates separated by sutures and the soft spots (fontanelles). That flexibility usually protects the brain during birth, but excessive or poorly directed force, particularly from a forceps or vacuum delivery, can crack the bone underneath.
Many birth-related skull fractures are simple linear cracks that heal on their own with no lasting harm. Others (depressed or basilar fractures, or fractures with bleeding underneath) are serious and can injure the brain. What separates a good outcome from a bad one is usually not the fracture itself but whether it was recognized, imaged, and monitored. This hub explains each fracture type and links to detailed pages on the signs of a skull fracture and on healing and long-term effects.
Types of infant skull fracture
Skull fractures are classified by their pattern and location. The type drives everything that follows: imaging, treatment, and prognosis.
| Type | What it is | Typical significance in newborns |
|---|---|---|
| Linear | A simple, thin crack through the full thickness of the bone, without displacement | The most common type; usually heals on its own, but needs imaging to rule out bleeding underneath |
| Depressed (“ping-pong”) | The bone is pushed inward, like a dent in a table-tennis ball | Can press on the brain; some elevate on their own, others need a procedure; requires specialist evaluation |
| Diastatic | A fracture that runs along or widens a suture line between skull bones | More common in newborns because sutures are not yet fused; associated with the rare “growing” fracture |
| Basilar | A fracture at the base of the skull | The most serious; risk of injury to nerves and blood vessels and of cerebrospinal fluid leak; a medical emergency |
A fracture is also described by whether it is closed (skin intact) or open, and whether it is displaced. Fractures frequently occur alongside a cephalohematoma (a collection of blood under the scalp covering) which can be the first visible clue that a fracture is present underneath.
Causes at birth
Most birth-related skull fractures involve mechanical force on the head. Common contributors include:
- Forceps delivery: the metal blades apply focal pressure to the skull; excessive or misapplied traction is a recognized cause of linear and depressed fractures.
- Vacuum extraction: the suction cup and traction can fracture bone and cause bleeding beneath the scalp or skull.
- Cephalopelvic disproportion: when the baby’s head is large relative to the mother’s pelvis, the head is compressed against the pelvic bones.
- Prolonged or obstructed labor: sustained pressure on the head.
- Difficult or precipitous delivery, malposition, or manual pressure during a complicated birth.
Instrument-assisted deliveries carry the clearest fracture risk, which is why the decision to use forceps or vacuum (and how they are applied) is central to many claims.
Signs and symptoms
Signs depend on the type and on whether the brain is affected. A simple linear fracture may show only a soft swelling; a serious fracture shows neurological signs. Warning signs include a visible dent or swelling on the head, a bulging or tense soft spot, unusual sleepiness or poor feeding, vomiting, a high-pitched cry, seizures, or bruising around the eyes or behind the ears. Our dedicated page on the signs of a skull fracture in a baby breaks these down by fracture type and by when to seek emergency care.
How an infant skull fracture is diagnosed
Diagnosis begins with a careful physical exam of a baby who had a difficult or instrument-assisted delivery, or who has a cephalohematoma or neurological signs. Imaging confirms it:
- CT scan is the standard for defining a fracture and, critically, for detecting bleeding inside the skull (such as an epidural or subdural hematoma) that can accompany it.
- Skull X-ray or ultrasound may be used in specific situations, but CT best shows both bone and brain.
- MRI may follow to assess the brain in detail when injury is suspected.
A recognized failure point in these cases is not imaging a baby who had clear risk factors (a difficult forceps or vacuum delivery with a cephalohematoma) and thereby missing a fracture with bleeding underneath.
Treatment
Treatment depends entirely on type and on whether the brain is involved:
- Linear fractures with no bleeding usually need only observation and follow-up imaging; they heal without intervention.
- Depressed fractures may be watched if mild; more significant depressions, or any pressing on the brain, may need a neurosurgical procedure to elevate the bone.
- Fractures with bleeding (epidural or subdural hematoma) can be an emergency requiring surgical evacuation.
- Basilar fractures require close monitoring for cerebrospinal fluid leak, nerve or vascular injury, and infection.
Was your baby’s skull fracture imaged, diagnosed, and monitored the way it should have been, especially after a forceps or vacuum delivery? A free records review will tell you honestly what the records show, including when there is no case.
Healing and long-term outlook
The reassuring reality is that most infant skull fractures, especially simple linear ones with no underlying brain injury, heal completely on their own, often within a few months, thanks to the extraordinary bone-healing capacity of infants. The concerning exceptions are the rare growing skull fracture (leptomeningeal cyst), and any fracture with brain injury, which drives the long-term picture. We cover timelines, growing fractures, when surgery is needed, and monitoring in depth on the skull fracture healing page.
Was it preventable? What the standard of care requires
Not every birth-related skull fracture is the result of negligence; some occur despite careful delivery. But many trace to preventable decisions: using forceps or vacuum when they were not appropriate or safe, applying excessive or misdirected force, continuing an instrument delivery that was failing instead of moving to cesarean, or, after delivery, failing to recognize and image a baby with obvious risk factors. The standard of care asks whether the instruments were indicated and correctly used, and whether an injured baby was properly evaluated and monitored afterward.
Legal options for families
A skull fracture claim is a medical-negligence claim: it asks whether the delivery or the follow-up care fell below the accepted standard and whether that failure caused lasting harm. These cases turn on the delivery records: the indication for and application of forceps or vacuum, the imaging that was or was not ordered, and the neurological monitoring afterward. Where a case is handled depends on where the birth occurred: Banville Law attorneys are licensed in New York and Washington, D.C.; The Weitz Firm attorneys are licensed in Pennsylvania and New Jersey; elsewhere, the alliance connects families with its vetted network of local birth injury attorneys.

Frequently asked questions
How common are skull fractures in newborns?
They are uncommon but well recognized, and the risk rises with instrument-assisted (forceps or vacuum) deliveries. Many are simple linear fractures that heal without complication.
Do infant skull fractures cause brain damage?
Most simple linear fractures do not. The risk of brain injury comes from depressed and basilar fractures, and especially from bleeding inside the skull that can accompany a fracture, which is why prompt imaging matters.
Are forceps and vacuum deliveries the main cause?
Instrument-assisted deliveries are the most common identifiable cause of birth-related skull fractures, though fractures can also result from cephalopelvic disproportion and prolonged or difficult labor.
Does a skull fracture always mean malpractice?
No. Some fractures occur despite appropriate care. A claim depends on whether the instruments were indicated and correctly used and whether the baby was properly evaluated afterward, questions the delivery records answer.
