II. Mechanism

  1. Concurrent Fracture dislocation (high energy injury)
    1. Talocalcaneonavicular joint
    2. Calcaneocuboid joint
    3. Naviculocuneiform joint
  2. Stress Fracture
    1. Tarsal Navicular Stress Fracture

III. Imaging

  1. XRay
    1. Avulsion Fracture
    2. Tarsal Navicular body Fracture
  2. Advanced imaging indications
    1. Tarsal Navicular Stress Fracture
    2. May be indicated per specialist recommendation to define Fracture lines and associated Soft Tissue Injury

IV. Management

  1. See Tarsal Navicular Stress Fracture
  2. Minor avulsion Fracture (low energy injury)
    1. Walking boot (CAM Boot) for 4-6 weeks
  3. Significant injury with suspected Ligamentous Injury
    1. Non-weight bearing and splint
    2. Orthopedic referral
  4. Surgery often required
