What is the treatment for a horse with a prolapsed frog?

Treatment of Prolapsed Frog in Horses

For a prolapsed frog in horses, gentle manual reduction under mild sedation is the recommended first-line treatment, followed by protective bandaging and addressing any underlying causes.

Assessment of Prolapsed Frog

Initial Evaluation

• Determine the severity and duration of the prolapse
• Assess for signs of:
  • Ischemia or necrosis of the prolapsed tissue
  • Secondary infection
  • Trauma to the surrounding structures
  • Bleeding from the affected area

Physical Examination

• Evaluate the horse's overall health status and vital signs
• Examine the affected foot carefully for:
  • Extent of prolapse
  • Presence of foreign bodies or penetrating injuries
  • Signs of infection (heat, swelling, discharge)
  • Associated lameness (grade severity)

Treatment Algorithm

1. Conservative Management (First-Line)

• For uncomplicated prolapsed frog without signs of ischemia or necrosis:
  • Administer mild sedation (avoid acepromazine which may worsen tissue prolapse) 1
  • Clean the affected area thoroughly with antiseptic solution
  • Gently reduce the prolapsed tissue manually 2
  • Apply protective bandaging to maintain reduction and prevent contamination

2. Wound Management

• If penetrating injury is present:
  • Clean and debride any necrotic tissue
  • Consider radiographs to assess depth of penetration and potential involvement of deeper structures 3
  • Grade the injury based on depth of penetration:
    • Grade 1: Superficial (involving only superficial corium)
    • Grade 2-3: Moderate depth
    • Grade 4: Deep (involving synovial structures) 3

3. Medical Management

• Administer appropriate antimicrobial therapy if infection is present or suspected 2
• Provide pain management with NSAIDs
• Consider tetanus prophylaxis if vaccination status is unknown

4. Surgical Intervention

• For complicated cases with:
  • Failure of conservative management
  • Extensive tissue damage
  • Deep infection
  • Synovial structure involvement
• Surgical options:
  • Debridement of necrotic tissue
  • Drainage of abscesses
  • Repair of damaged structures

Post-Treatment Management

Short-term Care

• Maintain clean, dry environment
• Change bandages regularly
• Monitor for signs of infection or deterioration
• Stall rest until healing begins

Long-term Management

• Consider therapeutic shoeing to reduce pressure on the frog 4, 5
• Gradually return to exercise as healing progresses
• Regular hoof care and maintenance

Prognosis

The prognosis depends on several factors:

• Severity of the prolapse
• Presence of complications (infection, synovial involvement)
• Timeliness of treatment

For uncomplicated cases treated promptly with conservative management, the prognosis is generally good with 91.4% of equids returning to previous level of soundness 3. However, cases involving synovial structures have a poorer prognosis, with only 29% regaining soundness 3.

Important Considerations

• Early intervention improves outcomes 3
• Hind foot injuries generally have better prognosis than forefoot injuries 3
• Frog pressure affects hoof expansion and should be considered when designing therapeutic shoeing 5
• Penetrating injuries to the central region of the foot without synovial involvement have favorable prognosis if managed early 3

Remember that proper hoof care and regular farrier visits are essential for prevention of recurrence and maintenance of hoof health.
