Suspected Tibia Fracture with Numbness After a Fall: Immediate Steps

A fall with possible tibia fracture and numbness is a potential emergency. Numbness suggests nerve or vascular compromise.

Immediate Actions

1. Do not weight-bear. Use crutches or ambulance.
2. Immobilize: Splint knee and ankle if trained; otherwise keep leg still.
3. Elevate above heart level to reduce swelling.
4. Ice (wrapped) 15–20 min/hour.
5. Go to ER/Urgent Care immediately.

Why Numbness Is a Red Flag

• Compartment syndrome: Swelling in closed fascial compartments → nerve/vascular compression → irreversible damage in hours. Surgical emergency.
• Peroneal nerve injury: Common fibular nerve at fibular neck → foot drop, lateral leg numbness.
• Vascular injury: Popliteal artery damage → pale, pulseless, cold foot.
• Displaced fracture fragments compressing nerves.

ER Evaluation

• X-rays (AP/lateral tibia/fibula, knee, ankle).
• CT if intra-articular or complex.
• Neurovascular exam (pulses, sensation, motor).
• Compartment pressure measurement if suspected.

Treatment

• Closed reduction + casting (non-displaced, stable).
• ORIF (plates, nails) for displaced/unstable fractures.
• Fasciotomy for compartment syndrome.
• Vascular repair if needed.

Do not wait. Numbness + fracture = urgent orthopedic/vascular assessment.
