Should a 6-year-old with a head laceration be sent to the emergency department for possible skull fracture or can it be repaired with staples at an urgent care without X‑ray capability?

Management of Head Laceration in a 6-Year-Old at Urgent Care Without X-Ray

You should risk-stratify this child using PECARN criteria before deciding whether to repair the laceration locally or transfer to the emergency department—the presence of a simple scalp laceration alone does not require transfer if the child meets very low-risk criteria. 1

Risk Stratification Using PECARN Criteria

For a 6-year-old child (≥2 years of age), assess the following clinical features to determine risk level 1:

Very Low Risk (Can Repair at Urgent Care)

The child can be safely managed at your urgent care if they have all of the following 1:

• Glasgow Coma Scale (GCS) = 15
• No loss of consciousness
• No vomiting
• No severe mechanism of injury (e.g., not a motor vehicle crash with ejection, death of another passenger, or rollover; not struck by high-impact object; not fall from >5 feet)
• No severe headache
• No signs of basilar skull fracture (hemotympanum, Battle sign, raccoon eyes, CSF otorrhea/rhinorrhea)
• No altered mental status (agitation, somnolence, repetitive questioning, slow response to verbal communication)

Children meeting these very low-risk criteria have <0.02% risk of clinically important traumatic brain injury and can safely forgo CT imaging. 1 You can repair the laceration with staples or sutures at your urgent care facility.

Intermediate Risk (Consider Transfer)

Transfer to the ED for possible CT imaging if the child has GCS = 15 but any of the following 1:

• History of any loss of consciousness
• Vomiting
• Severe mechanism of injury
• Severe headache

The risk of clinically important intracranial injury in intermediate-risk children is approximately 0.8%, and CT may be considered versus careful observation. 1

High Risk (Immediate Transfer Required)

Immediately transfer to the ED if the child has 1:

• GCS ≤ 14
• Signs of altered mental status
• Signs of basilar skull fracture

The risk of clinically important intracranial injury is approximately 4.3% in high-risk children. 1

Role of Skull X-Rays

Do not obtain skull X-rays—they are not indicated in the evaluation of pediatric head trauma. 1, 2 The ACR Appropriateness Criteria explicitly state that skull radiographs are insufficient to evaluate for traumatic injury because 1:

• Up to 50% of intracranial injuries occur without skull fracture
• Radiographs cannot detect intracranial hemorrhage, edema, or mass effect
• They have only 63% sensitivity for detecting skull fractures 2

The CDC guidelines give a high-level recommendation (Level B) that skull radiographs should not be used in diagnosis of pediatric mild traumatic brain injury or screening for intracranial injury. 2

Common Pitfalls to Avoid

• Do not be falsely reassured by the presence of only a scalp laceration—intracranial injury can occur with minimal external signs, especially in young children. 3
• Do not assume normal skull X-rays rule out intracranial injury—clinical examination using PECARN criteria is far more important than imaging for skull fracture. 4, 5
• Do not transfer all head lacerations reflexively—most children with isolated scalp lacerations and very low-risk PECARN criteria can be safely managed in urgent care. 1

Practical Algorithm

1. Assess GCS and perform focused neurological examination 1
2. Apply PECARN criteria systematically (check for LOC, vomiting, severe mechanism, severe headache, basilar skull fracture signs, altered mental status) 1
3. If very low risk: Repair laceration at urgent care with staples or sutures; provide head injury instruction sheet to parents 1
4. If intermediate or high risk: Transfer to ED for evaluation and possible CT imaging 1
5. Never obtain skull X-rays as they do not change management 1, 2
