Thrush: eliminating degraded keratin

Introduction: The Crucial Role of Keratin in Equine Canker

Canker is a chronic hoof disease characterized by an abnormal proliferation of horn tissue in the frog area. At the heart of this pathology is a problem of degraded keratin: abnormal, spongy, and infected horn that presents a major obstacle to healing.

Understanding why and how to eliminate this degraded keratin is essential for effectively treating canker and allowing healthy horn to regenerate.

What is Keratin and What is its Normal Role?

Keratin: Structural Protein of the Hoof

Keratin is a fibrous protein that forms the main component of the hoof wall, produced by specialized cells called keratinocytes. It provides mechanical protection, impermeability, structure, and controlled flexibility to the hoof.

Degraded Keratin in Canker: A Pathological Tissue

In canker, the normal keratinization process is profoundly disrupted, producing abnormal horn: spongy texture (soft, friable, resembling cauliflower), whitish to grayish color, disorganized structure, excessive moisture, foul odor, and chaotic proliferation.

This disruption is caused by chronic bacterial infection (Fusobacterium, Treponema), chronic inflammation, an anaerobic and moist environment, and excessive cell proliferation.

Why Eliminating Degraded Keratin is Essential

1. Reservoir of Infection

Degraded keratin constitutes a breeding ground for bacteria: its porous structure protects pathogens from topical treatments and maintains a bacterial biofilm that is difficult to eliminate. No antiseptic treatment can be fully effective as long as this reservoir is not removed.

2. Obstacle to Oxygenation

Degraded keratin creates a physical barrier that prevents oxygen from reaching underlying tissues, maintains a moist environment favorable to anaerobes, and suffocates healthy tissues. Healing is impossible under these conditions.

3. Prevents Regeneration of Healthy Horn

The mass of abnormal horn compresses the keratin-producing tissues, maintains inflammation, and sends a continuous pathological signal. Healing cannot begin until the degraded keratin is removed.

4. Maintains Inflammation and Promotes Extension

If not removed, degraded keratin gradually extends to the sole, wall, and periople, increasing the infected surface and potentially leading to permanent hoof deformation.

Debridement: Technique for Eliminating Degraded Keratin

What is Debridement?

Debridement is the removal of all dead, infected, or abnormal tissues. It should not be radical but rather resemble regular exfoliation. Its objectives: eliminate the reservoir of infection, expose healthy tissues, allow oxygenation, and create an environment favorable to healing.

Who Can Perform Debridement?

Debridement must be performed by a qualified professional: veterinarian (ideally for severe cases), experienced farrier, or specialized equine podiatrist. Never attempt debridement yourself without training. However, you can use a rasp to regularly exfoliate necrotic tissues.

Debridement Technique

Required materials: hoof knife, nippers, curette, sterile compresses, INTENSIVE OZONE CARE (recommended for disinfection).

Procedure:

1. Initial Cleaning: Picking and cleaning the hoof
2. Assessment of Extent: Identification of the entire affected area
3. Removal of Degraded Keratin: Gradually trim all abnormal horn, without causing bleeding
4. Cavity Cleaning
5. Immediate Application: Bagging session or INTENSIVE OZONE CARE to disinfect and protect

Frequency of Debridement

Every 2-4 weeks depending on progress, for a total duration of 3-12 months depending on severity. Consult our natural care routine for canker for a complete protocol.

Treatment After Debridement: INTENSIVE OZONE CARE

Why Ozone After Debridement?

Once the degraded keratin is removed, INTENSIVE OZONE CARE is the treatment of choice:

• Powerful Antibacterial Action: Eliminates residual bacteria (Fusobacterium, Treponema), penetrates deeply, no resistance possible
• Tissue Oxygenation: Delivers oxygen to deprived tissues, creates a hostile environment for anaerobes
• Stimulation of Healthy Keratinization: Promotes the production of normal keratin, accelerates healthy horn regeneration
• Anti-inflammatory: Reduces residual inflammation

Post-Debridement Treatment Protocol

1. Immediately after debridement: Fill the cavity with OZONE HOOF CARE, apply INTENSIVE OZONE CARE generously to the entire area, cover with a soaked compress, and protect with a bandage.
2. Daily Care: Gently clean, dry, apply INTENSIVE OZONE CARE twice daily, change the bandage daily.
3. Duration: Continue until the next debridement and several weeks after the last one. Never stop too early (risk of recurrence).

Evolution and Signs of Healing

Short term (1-2 weeks): disappearance of odor, reduction of inflammation, pink and healthy granulation tissue, no reformation of degraded keratin.

Medium term (1-2 months): formation of new and firm horn, gradual reduction of the cavity.

Long term (3-12 months): complete filling, normal quality horn, functional frog, no recurrence.

Warning signs: reappearance of spongy tissue, return of odor, worsening inflammation, purulent discharge, no healthy horn after 4-6 weeks. Consult immediately.

Prevention of Degraded Keratin Reformation

To learn more about prevention, consult our hoof problem prevention guide.

• Absolutely Dry Environment: Daily absorbent bedding, drained paddock, permanent dry shelter
• Rigorous Hygiene: Daily picking, regular cleaning, disinfection of equipment
• Continuous Preventive Treatment: Daily INTENSIVE OZONE CARE during treatment, then OZONE MUD CARE for prevention (wet season)
• Regular Veterinary Follow-up: Control debridements every 2-4 weeks

Conclusion

Degraded keratin is at the heart of canker pathology. Its complete and regular elimination by debridement is absolutely indispensable for healing.

Keys to success:

• ✅ Light but regular debridements: Every week, without ever pulling on necrotic tissues or causing bleeding.
• ✅ Daily treatment with INTENSIVE OZONE CARE: Disinfection, oxygenation, stimulation of healthy keratinization
• ✅ Absolutely dry environment: A prerequisite for healing
• ✅ Patience and rigor: Treatment is long (3-12 months) but healing is possible
