  • Problems complained of by the owner: At showjumping competition horse injured the heel of the front hoof with his hind hoof and injured his coronary band.

  • Stabling: In the box

  • Feed : Common for a sport horse

  • Bedding : Straw with shawings

  • The surface on which the horse most often moves: Arena with sand and non-woven fabric, grassy paddock

  • Frequency of hoof treatment : Shoeing at the regular interval of seven weeks.

  • Lameness, possible diagnosis: Coronary band injury in the heel part and a large inward rotation of the phalanx caused a crack of the coronary band in the heel part of the hoof.

4. Anamnéza:
  • Conformation:

The forelimb has a large inward rotation of the phalanx. The horse lands on the medial heel and the medial half of the hoof.

5. Case description:
  • Selected trim:

A horizontal incision was made below the lower end of the crack.

 

  • Shoe preparation:

The hoof was shod with Equilibrium shoe. The inner branch of the horseshoe was narrowed. It will sink easier on a soft surface and the pressure on the overloaded foot will be decreased. Breakover the shoe has been directed to the outer toe, i.e. in the direction of movement of a limb.

Fig. No. 4.- 6 .: Before next shoeing the condition of the hoof deteriorated. The hoof wall cracked again and the ongoing crack widened and deepened. The hoof wall in the heels was almost separated from the hoof joint.

Changes in the shoe choice and shoeing 

The detached hoof wall in the heel part of the hoof had to be removed up to the coronary band. The hoof incision was moved higher to the crown edge.

 

The  "Equilibrium" with spider plate (mercedes) was chosen for shoeing.

Result of the care

Recommended convalescence during healing until a healthy wall grows to two thirds of the wall.

Controlled movement of a horse in a riding arena with geotextiles surface.

 

Fig. No. 8 .: 4 weeks after the last procedure, the coronary band dropped and the exposed corium healed.

7. Follow up – Development of changes

The balance of the limb and hoof should be constantly monitored. Large inward rotation overloads the medial heel. Due to the big  sporting work load of the treated horse (showjumping "T"), I recommend after the season and according to the health of the horse to make a preventive horizontal cut about 1.5 cm below the coronary band on the medial side of the hoof to release pressure on the coronary band.
