Pathogenesis

Etiology

  • One of the most common causes of lameness in the shod and unshod horse.
  • Abnormal focal weightbearing on the sole of the foot.

Predisposing factors

General
  • Conformation   Musculoskeletal: conformation  - thin, dropped or flat soles; long toe/low heel.
  • Housing in wet conditions   →   soft soles.
  • Stony/rough ground.
  • Poor shoeing (shoe too small, too short, improperly positioned, loose)   →    weightbearing on sole, most commonly around the periphery of the sole, at the heels or at the junction of the bars and the walls at the heel ('corns').
  • Poor foot trimming   →    imbalance/hoof overgrowth   →    excessive impact at specific areas of the foot.
  • Unshod.
  • Overwork.
  • Heel pain   →    gait change   →    excessive impact or weightbearing at toe   →    toe bruising.
  • Some specific types of shoe may increase focal forces on the foot at particular sites, eg toe grabs.

Pathophysiology

  • Trauma to sole   →    damage to the soft tissues betwee the sole of the hoof and coffin bone (solar cushion and corium)   →    rupture of the small vessels in the area   →    inflammation, hemorrhage, swelling   →    pain.
  • Subsolar hematoma may result   →    increased pain and lameness.

Timecourse

  • Variable, may be acute or chronic.
