                   Breed:                  Czech warmblood

                   Sex:                      Mare

                   Age:                      6 years

                   Color:                    Chestnut

                   Work:                    Recreation

  • Potíže, na které si majitel stěžuje – Reason why the owner complain: Klisna vykazuje bolestivost hrudních končetin, nekomfortní pohyb zejména na nerovném a tvrdém povrchu.

  • Doba trvání potíží – Length of the problems: Klisna se v pohybu během posledního roku výrazně zhoršila

  • Ustájení – Stabling conditions: V boxu

  • Stelivo Bedding: Sláma

  • Povrch po kterém se kůň pohybuje: travnatý výběh

  • Frekvence úpravy kopyt – Frequency of the hoof care: Korektura kopyt v pravidelném intervalu každých osm týdnů.

  • Typ kování – Type of shoeing: bez podkování

  • Kulhání, případná diagnóza – Lameness and diagnosis: Klisna se pohybuje hůře na zpevnělém nebo nerovném povrchu i v kroku

Reason why the owner complains: The mare shows uncomfortable movement and significant crookedness of forelimbs.

Length of the problems:   Problems were probabaly caused by neglected hoof care at an early foal age.                             

Stabling conditions: In last year 24/7, previous conditions not know to the owner.

Bedding: Straw.

Surface, on which the horse moves most often: Grassy field.

Frequency of the hoof care:   Trim in regular 8 weeks interval.

Type of shoeing: Barefoot.

Lameness and diagnosis: Combined deviations of the forelimbs. 

4. History:

Characterisation of the changes:

The mare shows uncomfortable movement, caused by combined deviations of the forelimbs conformation. 

Conformation:

  • base wide stance 

  • Off-set carpus on both forelimbs

  • significant outward rotation of the whole forelimbs and phalanx toed in from the fetlock

  • hoof broken out in pastern joints

Shape of the hoof and pathologic changes:

  • hooves are broken out  

  • due to overload of the outer heel in the stance phase, the outer wall is underrun 

  • mare has thrush

  • Evaluation of the hoof care and of the type of shoeing:

Trimming was slightly neglected.

5. Problem description

6. Choisen solutions

Trimming:

Trimming of the whole hoof levels as much as possible:

  • bearing edge lateromedially and also dorsopalmarilly

  • medial side of the hoof is leveled to have enough space to drive the shoe nails.

Shoe preparation: 

With regard to mare’s 24/7 turnout, we have chosen this type of shoeing:

  • standard horse shoe 25/8 mm on which we will create extensions, to better support center of gravity of the limbs and simultaneously won’t increase pressure on already overloaded outer hell

  • with the help of the shoes we will try to shift the whole center of gravity on lateral side of the hooves while maintaining the same width of the both branches of the shoe

  • toes of the shoes will respect the movement of the limbs and dorso palmar balance with the help of rocker toe 

  • outer branch: widen the outer edge of the shoe with fuller and narrow inner edge with grinder to 25 mm

  • outer branch : widen the inner edge of the branch and narrow the outer edge diagonally with grinder to 25 mm.

 

These adjustements are made on the shoe on the ground surface. Shape of the weight bearing surface of the shoe must respect the latero-medial balance and hoof mechanism.

Shoeing:

Shoes were fitted in order to make the inner branch edge of the shoes follow the shape of hooves, while the outer branch outreached the hooves perimeter to even the lateromedial balance and improve the load of the limbs on outer overloaded side.

7. Follow up – Development of changes

Trimming effect:

By trimming the sole surface and leveling the medial side of the hooves was achieved improvement of lateromedial balance and more even impact

Changes in shoe choice and shoeing:Re-shod after 5 weeks

Follow ups and re-shoeing is recommended in 5-6 weeks intervals. According to the evaluation of the results of the previous shoeing I recommend to suggest next measures.
