Broken Foot Recognition: Symptoms, Red Flags, and Immediate Actions

A foot fracture (any of 26 bones) presents with a cluster of signs — no single symptom is definitive.

Classic Presentation

• Pain: Immediate, severe, weight-bearing aggravates; may be localized or diffuse.
• Swelling: Rapid (minutes-hours), often significant; compare to contralateral side.
• Ecchymosis: Develops over hours-days; may track to toes/sole (plantar ecchymosis = high specificity for calcaneus fracture).
• Deformity: Angulation, shortening, rotation; absent in non-displaced fractures.
• Functional loss: Inability/unwillingness to bear weight; antalgic gait.
• Tenderness: Focal over fracture site (navicular, 5th metatarsal base, calcaneus, cuboid).

Red Flags for Urgent Care

• Open fracture (bone visible/protruding) — cover with saline-moistened gauze, IV antibiotics, urgent OR.
• Neurovascular compromise (pulseless, pale, paresthetic, cool) — emergency reduction.
• Crush injury / compartment syndrome (tense swelling, pain on passive stretch).

Imaging & Diagnosis

• X-ray 3 views (AP, lateral, oblique) — first line.
• CT for complex articular (Lisfranc, calcaneus, talus).
• MRI if occult fracture suspected (navicular stress fracture) and X-ray negative.

Initial Management

RICE (Rest, Ice, Compression, Elevation), immobilization (posterior splint or boot), non-weight-bearing crutches, orthopedic follow-up within 1–3 days. Definitive treatment: casting, ORIF, or percutaneous fixation per fracture pattern.
