What is pedal osteitis?

• A. Demineralization of the solar margin of the distal phalanx
• B. Inflammation of the navicular bursa
• C. Deterioration of hoof wall keratin
• D. Fracture of the distal phalanx

Answer: (A)

Pedal osteitis is demineralization at the solar margin of the distal phalanx, meaning the coffin bone shows mineral loss in the area that bears the sole due to chronic inflammation or loading problems. This bone-focused pathology differentiates it from soft-tissue or surface issues, and it explains persistent hoof pain and lameness when the weight-bearing surface is affected. It’s not inflammation of the navicular bursa, not deterioration of hoof wall keratin, and not a fracture of the distal phalanx; those describe different structures or injury types. Understanding that the key change is loss of mineral density at the solar margin helps connect clinical signs to radiographic findings and appropriate hoof-care interventions.
