query: What are the recommended baseline radiographs for horses at high-risk for laminitis?
answer: Baseline radiographs, especially for high-risk horses, are recommended to allow comparison should laminitis be suspected later.  This allows for objective evaluation of the episode using measurements like Coronary extensor distance (CE), Sole depth (SD), Digital breakover (DB), Palmar angle (PA), and Horn:lamellar distance (HL). Normal HL values vary by breed and age.
