Prognosis

  • Good for return to soundness.
  • Guarded if sepsis present or extensive lesion.
  • Partial resection is now considered the preferred technique for keratoma removal because hoof wall stability is maintained, the complication rate is decreased and the convalescent time shortened. Preservation of as much hoof wall as possible is recommended, but at all times the entire lesion must be removed to minimize recurrence.
