EpistemisLocalized bone pain after minor trauma
Specialty: Musculoskeletal.
Why it occurs
- Stress fracture of the second or third metatarsal (typical in military recruits or long-distance runners)
- Stress fracture of the tibia or fibula
- Fracture due to insufficiency of the sacrum or femoral neck in osteoporotic patients
- Cortical bone fissure after direct contusion
- Trabecular microfracture due to severe osteoporosis after a fall
- Silent bone metastasis that weakens the cortex and fracture due to minimal trauma (pathological fracture)
Initial workup
Plain x-ray (may be falsely negative in the first 2 to 4 weeks of a stress fracture) | Magnetic resonance imaging of the affected bone (gold standard for detecting early trabecular bone edema) | Triphasic bone scan with Technetium-99.
red flags
Exquisite localized pain on palpation and when supporting the limb, which progressively worsens until ambulation is prevented, accompanied by visible macroscopic deformity of the bone diaphysis or tension hematoma in the limb (risk of displaced fracture or compartment syndrome).
Standard management
- Paracetamol — 1 g every 8 hours orally, of choice since classic NSAIDs could delay or interfere with biological bone consolidation
- Tramadol — 50 mg orally every 8 hours in case of moderate uncontrolled pain
- Cholecalciferol (vitamin D3, 2000 IU/day orally) together with Calcium carbonate (1000 mg daily) to optimize bone remodeling.
