"Hopper", a 10-year-old Morgan gelding, was evaluated for non-weight-bearing right thoracic limb lameness in June 2003. In April 2003, Hopper had been evaluated for left thoracic limb lameness. A diagnosis of white line disease affecting all four hooves was made, but laminitis was suspected to have been an initiating factor. Upon presentation in June, radiographs revealed severe, bilateral laminitis with hoof abscesses in the right hoof. Treatments included bilateral forelimb dorsal hoof wall resections, bilateral regional antibiotic perfusion, and administration of intravenous and oral antibiotics, analgesics and vasodilators. Serial radiography was performed to monitor the course of the disease and identify possible hoof abscesses. Contrast studies of the digital vasculature were performed. Hopper was discharged in August 2003 with a grave prognosis.
