    1. Metatarsal-phalangeal joint (MTP) inflammation
      1. Tenderness and swelling over the involved Metatarsal head
      2. Restricted Range of motion
    2. Metatarsal head palpably enlarged
  7. Imaging
    1. Weight-Bearing Foot XRay
      1. XRay Findings may lag symptom onset by 3-6 weeks
      2. Sclerosis and flattening of the involved articular surface of the Metatarsal head
      3. Widening and irregularity of Metatarsal head
      4. Flattening and collapse of MTP joint with cystic changes

      1. Consider when serial XRays fail to make the diagnosis
  8. Management
    1. NSAIDs
    2. Warm soaks
    3. Local Corticosteroid Injection
    4. Well padded shoes
    5. Stiff soled shoe or walking boot
    6. Anterior Metatarsal bar or pad
