Approach to the Critical Patient

Immediate priorities

Neurovascular emergency recognition

Stabilization and analgesic priorities

Escalation triggers

Conditions requiring immediate orthopedic consultation

Key decision points

Non-accidental trauma (NAT) screening

Procedural sedation planning

History

Mechanism and onset

Mechanism of injury

Timing and functional status

Symptom characterization

Primary symptoms

Alarm symptoms

Risk factors

Host and demographic risk factors

Background conditions increasing fracture risk

Prior physeal injury to same bone

Collateral history

Caregiver and witness information

Family history

Physical Exam

Vitals and general appearance

Vital sign assessment

General appearance

Musculoskeletal exam

Inspection

Palpation

Range of motion

Neurovascular exam

Distal neurovascular status — mandatory before and after any reduction or splinting

Compartment assessment

PITFALLS

Examination errors

Differential Diagnosis

Physeal fracture spectrum

Pathologic fracture

Osteomyelitis or septic joint

Laboratory Tests

Routine fracture assessment
