(infectious pododermatitis) 

Definition:

• Infection in claw (mainly lateral claw of hind limb & rare in forelimb) & it's enzootic disease.

• Characterized by inflammation of proximal area of claw & surrounding tissue  & may be complicated with phlegmon,necrosis & fistulae.

  

Causes:

1.Predisposing causes:

Wounds or cracks in claw due to :

1.Complication of FMD

2.Long standing of animal in wet bedding area

3.Walking of animal in stony roads

 

 

2. exciting causes:

•spherophrous necropherous (main cause)

•anaerobic streptococcus.

•Coryne bacterium.

• Depend on degree of affections & types of foot rot:

1.Affect interdigital space – animal beat weight on heels.

2.Lamness varying from moderate to dead degree

3.Bad condition of animal

•Off food

•Decrease milk yield

•Rise in body temperature

•Increase pulsation& respiration rate.

•Recumbency in some cases

4.Local symptoms

•Cutenous form:

 Ulcers or dermatitis or fibroma at interdigital space with signs of inflammation (hot, swelling & painful)

•S/C form:

Phlegmon above coronet & interdigital space discharging yellowish watery exudates through skin.

  

• Tendenous form:

Necrosis of deep flexor tendon – cutting & hyperextension of pedal joint.

•Articular form :

Septic podoarthritis – characterized by purulent fistula at the coronet discharging pus.

• Osseous form:

Ostitis & osteoperiostitis of hoof joint characterized by multiple abscess or False fistula.

 

Treatment:

5. lateral incision of claw affected (longitudinal perpendicular to the circular ).

6. Medial incision .

7. Appear 2 flaps ( dorsal & palmer ).

8. by needle enter in pastern joint & above it cut between 1st & 2nd phalanges .

9. Massive legation by chromic catgut.
