Approach to the Critical Patient

Immediate priorities

Limb threat screen

Analgesia and immobilization first-pass plan

Imaging decision points

Consultation triggers

History

Injury and risk context

Symptom and timeline

Mechanism

Baseline function and demands

Risk factors for delayed union or nonunion

Medication and bleeding considerations

Associated injury screen

Physical Exam

Focused foot and ankle exam

Inspection and skin

Palpation

Function

Neurovascular

Adjacent joint and injury patterns

PITFALLS

Differential Diagnosis

Lateral foot pain after injury

5th metatarsal tuberosity avulsion fracture

5th metatarsal diaphyseal stress fracture

Cuboid fracture

Lisfranc injury

Lateral ankle sprain

Peroneal tendon injury

Occult fracture

Coding anchors

Laboratory Tests

Selective labs only

Routine labs usually unnecessary

Procedural pathway labs

Open fracture or systemic risk labs

Bone health labs for recurrent stress pattern

Diagnostic Tests

Scoring Systems

Fracture zone classification

Stress fracture and nonunion classification

Radiographs

Standard imaging

Additional imaging considerations

Diagnostic pitfalls

MRI

Occult or stress injury pathway

Contraindications

CT

Surgical planning or complex morphology

Occult fracture clarification

Radiation considerations

Disposition

ED disposition and follow-up

Discharge criteria

Urgent orthopedics criteria

Follow-up timing

Weight-bearing plan

Treatment

Immediate life-saving interventions

Limb-threatening scenarios

Immobilization and Splinting

Lower extremity splint options

Immobilization principles

Post-splint checks

Reduction

Reduction usually not required

Analgesia and anesthesia support

Open fracture medications and timing

Antibiotics timing

Antibiotic selection for low-grade open fracture pattern

Tetanus prophylaxis

DVT prophylaxis when relevant

Routine pharmacologic prophylaxis usually not indicated for isolated foot fracture

High-risk features prompting individualized plan

Special Populations

Pregnancy

Imaging considerations

Analgesia considerations

Disposition and mobility

Geriatric

Higher complication risk
